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.

• Keep propane tank(s) below 38°C (100° F).
• Use only in well-vented areas. Provide at least a three-square-foot opening of
fresh, outside air for each 105.500 kJ/hr (100,000 BTU/Hr) of rating.
• Use only in places free of flammable vapors or high dust content.
• Keep heater away from strong drafts, water spray, rain, or dripping water.
• Use only the electrical voltage and frequency specified on model plate.
• Use only a three-prong, grounded extension cord.
• Use only the hose and factory regulator provided with the heater.
• Inspect hose assembly before each use of heater. If excessive abrasion or wear
is seen, or the hose is cut, replace before using heater. Use the replacement
hose assembly that is specified by the manufacturer.
• Keep heater at least six feet from propane tank(s). Do not point heater at
propane tank(s) within 6 m (20 feet).

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.
