I. SAFETYFIRST!!!

This heater is suitable for both mobile home and conventional home installation. Read all

instructions carefully before starting installation. Save this manual for future reference.

1. Read these instructions carefully. Failure to follow them could cause a

malfunction of the heater, damage to the heater, property damage, bodily

injury or even death.

2. Familiarize yourself with the heater’s operation. (See “Operation” section)

If you are not sure, ask your dealer for explanations on your heater’s

proper operation.

3. The burn pot of this heater is designed to burn premium grade wood

pellets. Pellets with too much fines and saw dust must be screened before

use. DO NOT USE WET PELLETS. Refer to the “Fuel Requirements”

section for more information.

4. Oil the circulation fan motor bearings every 6 months. See “Maintenance”

section for more details.

5. Check your local building codes regarding restrictions or installation

requirements. All installations must comply with local building codes.

6. This heater requires a floor protector beneath the heater and extending a

minimum of 6 inches (150mm) in front of the heater. This is to catch any

spillage which may occur during opening and closing of the doors. See

figure 1 for more information.

7. Use only UL/ULC listed Type PL or Type L venting for the exhaust

system. This heater is designed for use with 3-inch (76 mm) vent pipe.

Avoid long runs and too many bends. It may be necessary to increase the

size of the vent pipe to 4 inch (102 mm) if long runs and too many bends

are unavoidable. See “Venting System” section for more information.

8. Combustion of wood pellet fuel leaves ash in the heater and venting

system. These ashes must be removed from the heater and venting on a

regular basis (approximately once a week, more frequently for high ash

content fuels). See “Maintenance” section for more information. The

entire system must also be cleaned at the start of each heating season. A

yearly inspection of the venting is highly recommended.

Page 6

9. The heater must be turned off and allowed to cool before cleaning. Make

sure there are no hot ashes or embers present. Use a brush and scoop to

clean. Only use vacuum cleaners specifically designed for use with hot

ashes. Place all ashes in a sealed metal container with a tight, non

flammablefitting lid.

10. Store all pellet fuel in a sealed metal container at a safe distance (at least

36 inches / 1 meter) away from the heater. DO NOT place the fuel

within the installation clearances of the stove or within the space needed

for ash removal and start up.

11. This heater is POWER VENTED. The vent pipes have positive pressure

during operation. It is IMPERATIVE that all joints in the venting system

be SEALED to prevent any leakage of exhaust gases inside the house.

All joints must be sealed using high temperature silicone sealer (RTV).

Aluminum tape is not an adequate sealant.

12. Use of outside combustion air is highly recommended and is mandatory

in mobile home installations. Connect the air intake of the heater to the

exterior of the building with a noncombustible metal pipe with a

minimum diameter of 2 inches (50 mm) (Use APR Part No AK100). Use

of plastic pipe is not permitted.

13. This appliance is wired and grounded according to the CSA C22.1 code

for Canada and the NFPA70 code for the USA. Also, this heater meets

the fuel burning appliance installation codes NFPA 211 in the USA and

CSA B365 in Canada.

14. Do NOT operate the heater with the door open. Make sure the door and

any other opening in the stove are closed tightly during operation.

Inspect the gaskets of the door and other openings periodically to make

sure they are in good condition.

15. Replace broken or defective components only with parts provided by the

manufacturer. See WWW.KOZISTOVES.COM or contact your local

dealer to find out how to purchase replacement parts.

16. Follow this manual carefully for proper installation. If you are uncertain,

call your dealer. Most dealers have qualified and trained installers. We

highly recommend the use of their services.

Additional installation information can be found in the “Typical Installation Configura-

tions” section and your venting manufacturer/supplier’s literature.

INSTALLATION COMMENT: We recommend sufficient space be

provided (minimum 20 inches/500 mm) on each side of the heater to service

the equipment area. If this is not possible, a provision must be made to pull

the heater out for service.

1.2 Other Clearances and Recommendations

1. This heater must be mounted on a noncombustible material, placed

underneath the heater and extending a minimum of 6 inches (150 mm) in

front of the heater.

2. Clearances can ONLYbe reduced by means approved by local building or

fire officials in your area.

3. A safety certification label has been attached to the back of the heater. A

sample label is shown here to help you locate this label on your heater.

Please read all information on your heater’s label. All information on the

certification label supersedes any information contained in this manual.

Figure 5 Certification Label

2. ElectricalRequirements

1. This heater is an electrical appliance. The NorthAmerican versions of

this appliance require 120 Volts, 60 cycle and 3 Amps of electrical power.

The European versions of this appliance require 230 Volts, 50 cycles and

2Amps of electrical power. All heaters with an electric igniter require an

additional 300 watts of electrical power during the start up sequence.

2. The heater comes with a 5 ft. (1.5 M) long, grounded, electrical cord

suitable to plug into any standard residential electrical outlet. The

electrical outlet must be grounded.

3. When installed in a mobile home, the heater must be grounded to the steel

chassis of the home (unless this is not required by local code).

3. Fuel Requirements

3.1 Physical Properties

Your heater is very sensitive to fuel quality. Every effort should be made to use only the

best pellet fuel available in your area. This heater is designed for premium grade, 1/4 inch

(6.35 mm) or 5/16” (7.94mm) diameter wood pellets only. The following should assist

you in selecting the proper fuel.

If you find your fuel has too much fines and saw dust, the fuel may be screened before

use. DO NOT USE WET PELLETS under any circumstance. Longer fuel may cause

bridging of the auger and result in erratic feeding or jamming. Fines, binders, ash, moisture

will all cause your heater to plug up and not burn efficiently. “Poor” fuels require more

frequent cleaning; the ashtray must be emptied and the burn pot must be cleaned on a

weekly/possibly daily basis. Please refer to the “Maintenance” section for further

instructions on cleaning your heater.

3.2 Fuel Storage

All pellet fuel should be stored in a clean dry place and at a safe distance (at least 36

inches / 1 meter) away from the heater. DO NOT place the fuel within the installation

clearances of the heater or within the space needed for ash removal or starting of the

heater.

Burning any fuel other than wood pellets as described above

will void your heater’s warranty and may void any insurance.
