SAFETY

INFORMATION IMPORTANT: Read this owner’s manual carefully and completely

beforetryingtoassemble,operate,orservicethisheater.Improperuse

of this heater can cause serious injury or death from burns, ﬁre,

explosion, electrical shock, or carbon monoxide poisoning.

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning

resemble the ﬂu, with headaches, dizziness, and/or nausea. If you have these signs,

the heater may not be working properly. Get fresh air at once! Have heater

serviced. Some people are more affected by carbon monoxide than others. These

include pregnant women, people with heart or lung disease or anemia, those under

the influence of alcohol, and those at high altitudes.

PropaneGas:Propanegasisodorless.Anodor-makingagentisaddedtopropane

gas. The odor helps you detect a propane gas leak. However, the odor added to

propane gas can fade. Propane gas may be present even though no odor exists.

WARNINGS

FOR YOUR SAFETY

Do not use this heater in a space where gasoline or other

liquids having ﬂammable vapors are stored or used.

102588

SAFETY

INFORMATION

Continued

•Not for domestic use (inside living areas). Use heater for space heating only.

•Intended for temporary heating of buildings under construction, alteration, or repair.

•Install and use heater with care. Follow all local ordinances and codes.

•Use only in a well-vented area away from combustible materials.

•Provide proper ventilation. If not, excessive levels of carbon monoxide (CO)

and carbon dioxide (CO2) will form. Provide two fresh, outside air openings

for ventilation. One opening should be near the floor, the other opening near

the ceiling. Each ventilation opening must be at least 130 cm2.

•Never use heater where gasoline, paint thinner, or other highly ﬂammable

vapors are present. Use only in places free of flammable vapors or high dust

content.

•Do not use heater in basements. Propane gas is heavier than air. If a leak

occurs, propane gas will sink to the lowest possible level.

•Keep heater away from strong drafts, water spray, rain, or dripping water.

•Check heater for damage before each use. Do not use a damaged heater.

•Use only propane gas, I3P.

•Keep propane tank(s) below 38°C.

•Do not pull or twist gas hose.

•Unhook heater from propane and electrical supply before moving or when not

in use.

•Use only the electrical voltage and frequency speciﬁed on model plate.

•Use only the hose and regulator provided with the heater.

•Inspect hose before each use. If cut, worn, or damaged, replace before using

heater. Use the replacement hose assembly speciﬁed in this manual.

•Keep heater at least two meters from propane tank(s). Do not point heater at

propane tank(s).

•Minimum heater clearances from combustibles:

Outlet: 3 meters Sides: 1 meter Top: 2 meters Rear: 1 meter

•Locate heater on stable and level surface if heater is hot or running.

•Keep children and animals away from heater.

•Never block air inlet (rear) or air outlet (front) of heater.

•Never move, handle, or service a hot, operating, or plugged-in heater.

•Do not alter heater. Keep heater in its original state.

•Do not use heater if altered.

•Never attach duct work to front or rear of heater.

•Use only original replacement parts. This heater must use design-specific

parts. Do not substitute or use generic parts. Improper replacement parts could

cause serious or fatal injuries.

•Electrical installer: Follow all national and local codes.

THEORY OF

OPERATION

The Fuel System: The hose/regulator assembly attaches to the propane gas

supply. This provides fuel to the heater.

The Air System: The motor turns the fan. The fan pushes air into and around

the combustion chamber. This air is heated and provides a stream of clean, hot air.

The Ignition System: The piezo ignitor lights the burner.

The Burner Control System: This system causes the heater to shut down if

the ﬂame goes out.

PROPANE

SUPPLY

User must provide propane gas and propane tank(s).

Use this heater only with a propane vapor withdrawal supply system. The amount

of propane gas ready for use from propane tanks varies. Two factors decide this

amount:

1. The amount of propane gas in tank(s)

2. The temperature of tank(s)

This heater is designed to operate with a minimum 9-kg propane tank. You may

need two or more tanks or one larger tank in colder weather. Use a 45-kg tank for

longer operation or in very cold weather. Less gas is vaporized at lower tempera-

tures. Your local propane gas dealer will help you select the proper supply system.

INSTALLATION

WARNING

Review and understand the warnings in the Safety Informa-

tion Section, pages 2 and 3. They are needed to safely oper-

ate this heater. Follow all local codes when using this heater.

Test all gas piping and connections for leaks after installation

or servicing. Never use an open flame to check for a leak.

Apply a mixture of liquid soap and water to all joints. Bubbles

forming show a leak. Correct all leaks at once.

WARNING

1. Provide propane supply system (see Propane Supply, above).

2. Connect fuel gas connector on hose/regulator assembly to propane tank(s).

Tighten ﬁrmly using wrench.

IMPORTANT:

Position regulator so that hose

leaving the regulator is in a horizontal position (see Figure 3). This places the

regulator vent in the proper position to protect it from the weather.

4. Open propane supply valve on propane tank(s).

5. Check all connections for leaks. Apply mixture of liquid soap and water to gas

joints. Bubbles forming show a leak that must be corrected.

Never use an open ﬂame to check for a leak. Apply a mixture

of liquid soap and water to all joints. Bubbles forming show a

leak that must be corrected. Correct all leaks at once.

6. Close propane supply valve.

Provide proper ventilation. If proper fresh, outside air ventilation

is not provided, carbon monoxide poisoning can occur. Provide

two fr esh, outside air openings for ventilation. One opening

should be near the floor, the other opening near the ceiling.

Each ventilation opening must be at least 130 cm2. Provide

proper fresh, outside air ventilation before running heater.
