WHEN AN EXISTING CATEGORY I HEATER IS REMOVED OR

REPLACED, THE ORGINAL VENTING SYSTEM MAY NO LONGER

BE SIZED TO PROPERLY VENT THE ATTACHED APPLIANCES.

The effects of an improperly sized venting system can

include but not limited to: the formation of

condensate, leakage, spillage etc. The following test

procedure is required:

WARNING

CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each appliance connected

to the venting system being placed into operation could result in carbon

monoxide poisoning or death.

The following steps shall be followed for each appliance connected to

the venting system being placed into operation, while all other

appliances connected to the venting system are not in operation:

1) Seal any unused openings in the venting system.

2) Inspect the venting system for proper size and horizontal pitch, as

required in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the

Natural Gas and Propane Installation Code, CSA B149.1 and these

instructions. Determine that there is no blockage or restriction,

leakage, corrosion and other deficiencies which could cause an

unsafe condition.

3) As far as practical, close all building doors and windows and all

doors between the space in which the appliance(s) connected to

the venting system are located and other spaces of the building.

4) Close fireplace dampers.

5) Turn on clothes dryers and any appliance not connected to the

venting system. Turn on any exhaust fans, such as range hoods and

bathroom exhausts, so they are operating at maximum speed. Do

not operate a summer exhaust fan.

6) Follow the lighting instructions. Place the appliance being inspected

into operation. Adjust the thermostat so appliance is operating

continuously.

7) Test for spillage from draft hood equipped appliances at the draft

hood relief opening after 5 minutes of main burner operation. Use

the flame of a match or candle.

8) If improper venting is observed during any of the above tests, the

venting system must be corrected in accordance with the National

Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or Natural Gas and

Propane Installation Code, CSA B149.1.

9) After it has been determined that each appliance connected to the

venting system properly vents when tested as outlined above,

return doors, windows, exhaust fans, fireplace dampers and any

other gas-fired burning appliance to their previous conditions of use.

2.0 INSTALLER RESPONSIBILITY

WARNING:

FIRE OR EXPLOSION HAZARD

The heater and related gas piping and wiring must be installed only by individuals or firms well qualified and

licensed in the required field of work.

Read and understand this manual in its entirety BEFORE you install this heater. If you have any questions call

your local representative. Verify that the fuel on the installation site is the same as what is required for this

heater. Check heater for damage or missing parts. If damage has occurred, notify carrier or point of purchase

at once for reconciliation of damaged goods. We are not responsible for transit damage. Do not install if

heater is damaged.

If you do not understand any of the safety or hazardous warnings contained in this manual, or have

questions or concerns about the installation, operation, maintenance or service of this heater, or any other

questions or concerns relating to this heater, you MUST CALL THE FACTORY at the telephone number noted

on the front cover of this manual or as detailed on the rating plate on the heater before operating this

heater.

Verify that model, input & length is what was ordered and is appropriate for installation. If heater is too small

for the heating load of the building, property damage can occur due to freezing. If unit is too large, severe

heat damage call occur to the building and/or its contents, fire, explosion, injury or death. If in doubt compare

heat loss of building with unit on site. If you are unable to calculate heat loss, call your local representative

for assistance.

Installation shall be in accordance with local codes. (See ‘CODE COMPLIANCE’).

If installation requires tilting, DO NOT over tilt the unit. Units are certified for installations up to 45°; however,

the maximum recommended tilt is 25°.

Install unit according to the “Clearance to Combustibles” for that particular heater and type of installation.

Make sure that clearances are maintained from vehicles parked below or in front of heater. Take into

consideration hoists. Failure to do so could result in property damage, injury or death.

Make sure unit is adequately suspended from ceiling or roof. Select hanging location that has adequate

strength to support heater.

This heater needs fresh air for safe operation and must be installed so there are provisions for adequate

combustion and ventilation air. In the USA, do not operate this heater without installing air intake hood or

duct (pin #800209) and exhaust/chimney vent in a residential garage application. In Canada, the outside air

intake is optional for residential garages. This heater must not be connected to a chimney flue serving a

separate solid-fuel burning appliance. This heater must only be installed with the venting that it is certified

for. Refer to the installation instructions for installation details. See pages 34 & 35)
