absence of local codes, with the NATIONAL FUEL GAS CODE,

ANSI Z223, latest edition. If you cannot reference these codes,

DO NOT attempt to install this unit.

•Any safety screen or guard removed for servicing an

appliance must be replaced prior to operating the heater.

•The appliance and its appliance main gas valve must be

disconnected from the gas supply piping system during any

pressure testing of that system at test pressures in excess of

1/2 psig (3.5 kpa).

•The appliance must be isolated from the gas supply piping

system by closing its equipment shut-off valve during any

testing of the gas supply piping system at test pressures equal

to or less than 1/2 psig (3.5kpa).

•DO NOT use this heater in recreational vehicles, bedrooms or

bathrooms.

•If this is the ONLY gas appliance, we recommend a

minimum 200 pound cylinder with a fill gauge. Use of a 100

pound cylinder is not recommended. Other household gas

appliances may require the tank size to be larger. Do not

operate the vent-free heater if the fuel level in the propane

tank is below 1/4 full.

•DO NOT use this heater if any part of it has been submerged

under water. Immediately call a qualified technician to inspect

the appliance and replace any part of the control system and

any gas control which has been under water.

•Any outside air ducts in the fireplace shall be permanently

MUST BE CLOSED AND SEALED.

•Young children should be carefully supervised when they

are in the same room as the appliance.

•An unvented room heater having an input rating of more

than 10,000 btu per hour shall not be installed in a bedroom

or a bathroom.

WARNING: During manufacturing, fabricating and

shipping, various components of this appliance are

treated with certain oils, films or bonding agents. These

chemicals are not harmful but may produce annoying

smoke and smells as they are burned off during the

initial operation of the appliance, possibly causing

headaches and eye/lung irritation. This is a normal and

temporary occurrence.

For Installation of High Altitude

When installing this fireplace at an elevation above 2,000 feet

(in the United States), it may be necessary to decrease the

input rating by changing the existing burner orifice to a smaller

size. Input should be reduced four percent (4%) for each 1,000

feet above sea level, unless the heating value of the gas has

been reduced, in which case this general rule will not apply. To

identify the proper orifice size, check with the local gas utility.

Consult your local gas utility for assistance in determining the

proper orifice for your location.

Provisions for Adequate Combustion and Ventilation Air

The National Fuel Gas Code, ANSI Z223.1

defines a

confined space as a space whose volume is less

than 50 cubic feet per 1,000 Btu per hour (4.8m3per

kw) of the aggregate input rating of all appliances

installed in that space and an unconfined space as a

space whose volume is not less than 50 cubic feet

per 1,000 Btu per hour (4.8 m3per kw) of the aggre-

gate input rating of all appliances installed in that

space. Rooms communicating directly with the

space in which the appliances are installed, through

openings not furnished with doors, are considered a

part of the unconfined space.

WARNING: This heater shall not be installed in a

confined space or unusually tight construction unless

provisions are provided for adequate combustion

ventilation air.

Today's homes are built more energy efficient than ever. New

materials, increased insulation and new construction methods

help reduce heat loss in homes. Home owners weather strip

and caulk around windows and doors to keep the cold air out

and the warm air in. During heating months, home owners

want their homes as airtight as possible.

While it is good to make your home energy efficient, you need

fresh air. All fuel-burning appliances need fresh air for proper

combustion.

Supplying Adequate Ventilation

This appliance must be installed in an unconfined space.

The following information will help you classify your space

and provide adequate ventilation for complete combustion.

An Unconfined Space has a minimum volume of 50 cubic

feet for each 1000 BTU/Hr input rating of all appliances in the

space. (4.8 M3per kw), (cubic feet equals length x width x

height of space).

A Confined Space has a volume of less than 50 cubic feet

for each 1000 BTU/Hr input rating of all appliances in the

space, (4.8M3per kw), (cubic feet equals length x width x

height of space).

Determining if You Have a Confined or

Unconfined Space

Use this worksheet to determine if you have a confined or

unconfined space.

Space: Includes the room in which you will install heater plus

any adjoining rooms with doorless passageways or ventilation

grills between the rooms.

1. Determine the volume of the space (length x width x

height).

Length x Width x Height = _____cu. ft. (volume of space)

Example: Space size 25’ (length) x 25’ (width) x 8’ (ceiling

height) = 5,000 cu. ft. (volume of space)

If additional ventilation from adjoining room(s) is supplied

with grills or doorless openings, add the volume of these

rooms to compute the total volume of the applicable

space.

2. Divide the space volume by 50 cubic feet to determine the

maximum BTU/Hr the space can support.

________(volume of space) ÷50 cu. ft. = (Maximum BTU/

Hr the space can support.

Example:

5,000 cu. ft. (volume of space) ÷50 cu. ft. = 100

or 100,000 (maximum BTU/Hr the space can support)

3. Add the BTU/Hr of all gas burning appliances in the space.

Gas range BTU/Hr

Vented gas heater BTU/Hr

Gas fireplace logs BTU/Hr

Other gas appliances* + BTU/Hr

Total = BTU/Hr

Example:

Gas range 60,000 BTU/Hr

Vent-free logs + 29,000 BTU/Hr

Total = 89,000 BTU/Hr

*Do not include direct-vent gas appliances. Direct-vent draws

combustion air from the outdoors and vents to the outdoors.

4. Compare the maximum BTU/Hr the space can support

with the actual amount of BTU/Hr used.

__________ BTU/Hr (maximum the space can support)

__________ BTU/Hr (actual amount of BTU/Hr used)

Example:

100,000 BTU/Hr (max. the space can support)

89,000 BTU/Hr (actual amount of BTU/Hr used)

The space in the above example is an unconfined space

because the actual BTU/Hr used is less than the maximum

BTU/Hr the space can support. If the space had been

confined, your options would be as follows:

A. Rework worksheet, adding the space of an adjoining

room. If the extra space provides an unconfined

space, remove door to adjoining room or add ventila-

tion grills between rooms. See Ventilation Air From

Inside Building.

B. Install a lower BTU/Hr heater, if lower BTU/Hr size

makes room unconfined.

Converting Confined Space to Unconfined

Space

Additional volume to convert a confined to an unconfined

space could come from an adjoining space. When using an

adjoining space, you can provide two permanent openings:

one within 12" of the ceiling and one within 12" of the floor on

the wall connecting the two spaces (see options 1 and 3,

Figure 2), or remove the door into the adjoining room.

Ventilation Air From Outdoors for Unusu-

ally Tight Construction

WARNING: If the area in which the heater may be

operated is smaller than that defined as an unconfined

space or if the building is of unusually tight construction,

provide adequate combustion and ventilation air by one

of the methods described in the National Fuel Gas Code,

ANSI Z223.1/NFPA 54, Section 5.3 or applicable local

codes.

76683

Unusually tight construction is defined as construction

where:

a. walls and ceilings exposed to the outside atmosphere have

a continuous water vapor retarder with a rating of one perm

(6 X 10.11 kg per pa-sec-m2) or less with openings gasketed

or sealed and

b. weather stripping has been added on openable windows

and doors and

c. caulking or sealants are applied to areas such as joints

around window and door frames, between sole plates and

floors, between wall-ceiling joints, between wall panels, at

penetrations for plumbing, electrical and gas lines and at

other openings.

If your home meets all of the three criteria above, you must

provide additional fresh air.

You may provide two permanent openings: one within 12" of

the ceiling and one within 12" of the floor. Connect these items

directly to the outdoors or spaces open to the outdoors. These

spaces include attics and crawl spaces. Follow the

National

Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for

Combustion and Ventilation

for required size of ventilation grills

or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into

attic if attic has a thermostat-controlled power vent. Heated air

entering the attic will activate the power vent.

minimum of 2" clearance from any

part of the heater to any of the

ventilation openings.

76683

Installation

Unpacking

Open both cartons and remove the logs and the chassis.

Remove each of the logs by gripping at either end of the log

while avoiding any undue pressure. Please note that the logs

have been marked for positive identification.

The cartons for all models contain the following: grate/burner

assembly, front, middle and rear logs, top twig, 2 screws, 2

brackets and a bag of volcanic ash.

Fireplace Preparation

The fireplace needs to be prepared before installing the unit:

A. Turn off the gas supply if the gas line has been run to the

fireplace.

B. WARNING: Before installing logs in fireplace, the

chimney flue and firebox must be cleaned of soot,

creosote, ashes and loose paint by a qualified chimney

cleaner or sooting will occur.

Note: If your fireplace has been cleaned using chemicals or

solvents, these products may have been absorbed into the

fireplace hearth and walls and will be burned off during the

initial break-in period.

C. Any outside air ducts and/or ash dumps in the fireplace shall

be permanently closed and sealed at the time of appliance

installation. This will prevent drafts from disturbing the

flames and interfering with complete combustion of the gas

fuel.

Location

When gas logs are to be installed in a fireplace, inspect the

area surrounding it for possible air drafts that may affect the

flames and possibly cause sooting. Such drafts may be caused

by a ceiling fan near the fireplace, a hot air furnace register or

an open door. When burning the logs, carefully observe the

effect of possible drafts on the flames and take appropriate

measures to eliminate them. For example, the ceiling fan may

be cut off, the hot air register closed, etc.

Centrally locate the gas logs in the fireplace deep enough into

the firepit to accomplish an adequate draft (if use as a vented

appliance is planned). Ensure that the front feet of the grate sit

inside the front edge of the fireplace. Be sure fireplace meets

minimum fireplace dimensions.

To avoid any movement of the unit during operation, screw

the chassis to the floor of the fireplace using the screws

provided. Failure to do so could cause gas leaks.

Holes are provided just behind the front grate legs and should

be used for securing the log set. After locating the chassis

correctly in the fireplace, mark the hole positions on the

fireplace floor. Drill two 1/8” diameter holes approximately 1/2”

deep.

Use the two screws to secure the chassis to the fireplace floor.

(Fig. 3)

Clearances

NOTE: The following instructions regarding installation clear-

ances and the use and installation of a canopy apply to use of

the appliances as an unvented space heater in permitting

jurisdictions. When installed as a vented decorative gas

appliance, the clearances noted below and the use of a heat-

deflecting canopy are not required.

However, it is recommended that these instructions be followed

even when the appliance will be used as a vented decorative

appliance in case local codes change to allow unvented space

heaters or in the event that the flue damper is inadvertently

closed.

Clearances for unvented installation in existing fireplaces,

(jurisdiction permitting)

1. Sidewall Clearances: Clearances from the side of the

fireplace opening to any combustible wall should not be less

than 2”. (Fig. 4A and 4B)

2. Ceiling Clearances: The ceiling height should not be less

than 62" from the top of the fireplace opening. (Fig. 4A)

3. Mantel Clearances: The use of a canopy* is optional

depending on mantel clearances to the fireplace opening

and projection profile.

NOTE: Mantel clearances may differ for each vent-free

firebox. Refer to the firebox installation instructions for

clearances.

A. Mantel profile: The minimum distance above the

fireplace opening to combustible material projecting 1¹⁄₂"

(tile moldings, breast boards, etc.) is 12¹⁄₂".

Combustible material projecting 6" (a mantel shelf, for

example) requires a minimum clearance of 19" above the

fireplace opening. Required clearance varies with the

amount of projection. (Fig. 4C)

The mantel profile must fall within the cross-section

shown in Figures 4C or 4D.

B. Heat resistant material: Any heat resistant material

suitable for a continuous operating temperature of 120°C

(248°F) must cover the wall surface directly above the

fireplace opening and extend the full width of the

fireplace opening for a distance of 10" above the

opening. (Fig. 4C)

Fig. 3 Use two (2) screws to secure the chassis to the fireplace

floor.

Gas Connection

Check Gas Type. Use only the gas type indicated on the

heater's rating plate. If the gas type indicated on the plate is not

your type of gas supply, DO NOT INSTALL. Contact your

dealer for the proper model.

WARNING

DANGER OF PROPERTY DAMAGE,

BODILY INJURY OR DEATH.

Make sure the heater is equipped to operate on

the type of gas available. Models designated as

natural gas are to be used with natural gas only.

Heaters designated for use with liquefied petro-

leum (LP) gas have orifices sized for commer-

cially pure propane gas. They cannot be used

with butane or a mixture of butane and propane.

Gas Piping. The gas supply line must be of an adequate size

to handle the BTU/HR requirements and length of the run for

the unit being installed.

Determine the minimum pipe size from the piping size chart on

Page 9. The normal gas connection at this appliance is 1/2"

NPT made at the left of the unit.

Always use an external regulator for all LP installations to reduce

the supply tank pressure to a maximum of 14" w.c. This is in

addition to the regulator fitted to the heater.

WARNING: Connecting directly to an unregulated

LP tank can cause an explosion.

All piping must comply with local codes and ordinances or with

the National Fuel Gas Code (ANSI Z223.1), whichever applies.

Gas Line Connection

If installation is for L.P. gas, have L.P. installer use two-stage

regulation and make all connections from storage tank to

heater. Refer to the National Fuel Gas Code for the proper

supply tank size with the Btu's/Hr requirements. If this is the

ONLY gas appliance, we recommend a minimum 200 pound

cylinder with a fill gauge. Use of a 100 pound cylinder is not

recommended. Other household gas appliances may require

the tank size to be larger.

Use two pipe wrenches when making the connection to the

valve to prevent turning or damage to gas valve or regulator.

Connection between the manual shut-off valve and the gas

valve can be made with a CSA design certified flexible connec-

tor if allowed by local codes. A drip leg (sediment trap) must

be installed. (Fig. 5) Tighten all joints securely.

CAUTION: Failure to install a drip leg (sediment trap) may

result in improper combustion that will produce soot.

Under no circumstances should internally zinc alloy coated piping be used. According to the LP-Gas Code and National Fuel Gas

Code - If galvanized piping is used, it must be EXTERNALLY coated only! Galvanized water pipe used for gas installations will

result in reduced gas pressure and gas leaks.

76683

NOTE: To determine the size of the branch gas line from the main gas line to the fireplace, enter the tables below (for iron

pipe or copper tubing) using the distance from the gas meter or second stage regulator to the furthest appliance on the

gas system. Select a pipe or tube diameter which has enough capacity to meet the maximum input requirement of the

fireplace. Regardless, do not use less than 1/2" diameter for the branch line. For any distances required longer than

shown in these tables, refer to the National Fuel Gas Code.

NOTE: There may be a local gas utility requirement specifying a minimum diameter for gas piping. All units require a 1/2 inch pipe

connection at the gas valve.

Gas Pressure Check

The gas inlet pressure specified in Table 1 is the pressure

where the field-installed gas line connects to the gas control.

This is measured at the inlet test port on the gas valve in the

appliance. Ensure that pressure is as shown in Table 1.

The manifold pressure is controlled by the gas valve and should

be checked at the pressure test points as shown in Figure 9 on

Page 11. The pressure connections accept 1/4” I.D. hose or

tubing.

The pressure should be checked with the appliance burning on

high (highest setting) and all other appliances turned on. One

must then read the manometer and if pressures are not 10.0”

w.c. for LP or 3.5” w.c. for Natural gas the inlet pressure must

be adjusted or increased until the proper pressures are at-

tained. If these pressures are greater than 10.2” w.c. for LP or

3.7” w.c. for Natural gas, contact your gas supplier before

operating the appliance.

Pressure is tested by loosening (do not remove) the screw in

the test port and sliding tubing onto the test port.

CAUTION: If the appliance's operating pressures are not

checked and adjusted, improper combustion may result in

soot being produced. Record the results of the gas

pressure check on the appropriate documents.

Testing the Gas Piping. Test all piping for leaks. When

checking gas piping to the heater with gas pressure less than

1/2 psi, shut off manual gas valve for the heater. If gas piping is

to be checked with the pressure at or above 1/2 psi, the heater

and manual shut off valve must be disconnected during testing

to prevent damage to the regulator on the unit. (SEE WARN-

ING).

To ensure that the gas lines and connections do not have any

leaks, a pressure test should be performed. Only a qualified

installer should perform the pressure test to ensure that

the unit is not damaged by high pressures!

WARNING: Be sure that the gas type indicated on the

gas log rating plate concurs with the gas system in your

building.

If you connect natural gas to an LP gas unit, you may be

unable to ignite the pilot. If the pilot does ignite, the burner

flame on the low setting will be bright blue but only 1/4” to 1/2”

long and most likely lifting off the burner ports. If this is the

case, turn the unit off immediately.

If you connect LP gas to a natural gas unit, the burner flame

on the low setting will be about 6” - 8” long. On the high setting,

the burner flames will be bright yellow and about 10” in length.

Turn the unit off immediately! If the unit is allowed to run in

this condition, substantial amounts of soot will be generated

and emitted into the house.

Log Assembly

1. Unpack and identify the four (4) logs by referring to Figures

6, 7 and 8.

2. Position back log into “V” log retainers ensuring that back

grate uprights are positioned in log notches.

3. Position front log with front grate bars fitting into log notches.

Log must fit down onto grate bars. (No gap under log).

4. Position middle log so notches in log fit snugly onto log

retaining bars. NOTE: Pin on left hand side of grate

prevents log from moving forward which would create flame

impingement from the yellow flame burner.

5. Position log retaining clip parallel with back edge of middle

log. Push pointed end of clip into log and fasten clip to bar

with screw provided. NOTE: This clip maintains upright

position of middle log to optimize glowing ember front

surface. (See clip location in Figure 6)

When you have completed these steps, compare log positions

with Figure 6. The logs must be positioned as illustrated.

The top twig may be positioned as shown in either Figure 7 or

Figure 8.

The top twig must be placed in the notches provided on top of

the rear and center logs. The front of the top twig is to rest of

the large knot on the front log.

CAUTION: Proper location is critical. When positioning the log

set, make sure that the logs do not interfere with the sides of

the fireplace before securing the chassis.

Fireplace Screen

A fireplace screen must be in place when the appliance

is operating and unless other provisions for combustion air

are made, the screen must have openings for the introduction

of combustion air.

Decorative Volcanic Ash

The volcanic ash from the bag provided should be sprinkled

around the base of the logset DO NOT place any material,

including volcanic ash on burner, pilot or logs.

WARNING: Failure to position the parts in accordance

with this diagram or failure to use only parts specifically

approved with this heater may result in property damage

or personal injury. See instruction manual for further

information.

WARNING

DANGER OF PROPERTY DAMAGE,

BODILY INJURY OR DEATH.

Never use a match or open flame to test for leaks. Never

exceed specified pressures for testing. High pressures

may damage the appliance regulator which would

require replacement. Liquid petroleum (l.p.) is heavier

than air and it will settle in any low area, including open

depressions and it will remain there unless area is

ventilated.

Never attempt start-up of unit before thoroughly ventilat-

ing area.
