SAFETY

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

before trying to assemble, operate, or service this heater. Improper

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

explosion, electrical shock, and carbon monoxide poisoning.

Carbon Monoxide Poisoning: Some people are more affected by carbon

monoxide than others. 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.

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.

THEORY OF

OPERATION

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

supply. The propane gas moves through the solenoid valve and out the nozzle.

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 burner control sends voltage to the ignitor. The

ignitor ignites the fuel and air mixture.

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

flame goes out. The motor will continue to run, but no heat is produced.

PROPANE

SUPPLY

Propane gas and propane tank(s) are to be furnished by the user.

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)

The chart below shows the number of 45-kg (100-pound) tanks needed to run this

heater. Do not operate this product with any tank smaller than 45-kg (100 pounds).

Less gas is vaporized at lower temperatures. You may need a larger tank in colder

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

system.
