VENTILATION
WARNING: Follow the minimum fresh, outside air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poison- ing can occur. Provide proper fresh, outside air ven- tilation before running heater.
Provide a fresh air opening of at least three square feet for each 100,000 Btu/Hr rating. Provide extra fresh air if more heaters are being used.
OPERATION
WARNING: Review and understand the warnings in the Safety Information section, page 2. They are needed to safely operate this heater. Follow all local codes when using this heater.
TO START HEATER
1.Follow all installation, ventilation and safety information.
2.Locate heater on stable and level surface. Make sure strong drafts do not blow into front or rear of heater.
3.Plug power cord of heater into a
Extension Cord Size Requirement
Up to 50 feet long, use 18 AWG rated cord. 51 to 100 feet long, use 16 AWG rated cord. 101 to 200 feet long, use 14 AWG rated cord.
7.Thermostat Operation Only: During normal thermostat op- eration, heater will cycle off when air temperature rises to ther- mostat setting. When air temperature drops sufficiently below thermostat setting, the electric motor and fan will begin to run. After 15 to 60 seconds, heater burner should automatically ignite and provide heat to maintain temperature setting.
TO STOP HEATER
1.Tightly close propane supply valve on propane tank(s).
2.Wait a few seconds. Heater will burn gas left in supply hoses.
3.Turn on/off switch to the OFF position.
4.Unplug heater.
STORAGE
CAUTION: Disconnect heater from propane sup- ply tank(s).
1.Store propane tank(s) in safe manner. See Chapter 5 of Stan- dard for Storage and Handling of Liquefied Petroleum Gases, ANSI/NFPA 58 and/or CAN/CGA B149.2. Follow all local codes.
2.Place plastic cover caps over brass fittings on inlet connector and hose/regulator assembly.
3.Store in dry, clean, and safe place. Do not store hose/regulator assembly inside heater combustion chamber.
4.When taking heater out of storage, always check inside of heater. Insects and small animals may place foreign objects in heater. Keep inside of heater free from combustible and for- eign objects.
4.Plug extension cord into a 120 volt/60 hertz,
5.Open propane supply valve on propane tank(s) slowly.
Note: If not opened slowly,
6.Turn thermostat control knob fully counterclockwise to the "COOLER" position. Turn ON/OFF switch to the ON posi- tion. Turn thermostat control knob slowly clockwise until elec- tric motor and fan begin to run. Heater will start in approxi- mately 3 seconds. Adjust thermostat control knob to WARMER or COOLER setting as needed.
Note: If heater does not start after 3 seconds, the ignition con- trol will automatically attempt to start heater one time. If heater fails to start on this attempt, the safety control will "lock out" and no further automatic restarts will be attempted. This could occur if air remains in fuel line. If heater fails to start on this attempt, turn ON/OFF switch to OFF position. Wait ten sec- onds for safety control to reset, then turn ON/OFF switch back to ON position and try to start heater again.
MAINTENANCE
WARNING: Never service heater while it is plugged in, connected to propane supply, operating, or hot. Severe burns and electrical shock can occur.
1.Keep heater clean. Clean heater annually or as needed to re- move dust and debris. If heater is dirty or dusty, clean heater with a damp cloth.
2.Inspect heater before each use. Check connections for leaks. Apply mixture of liquid soap and water to connections. Bubbles forming show a leak. Correct all leaks at once.
3.Inspect hose/regulator assembly before each use. If hose is highly worn or cut, replace.
4.Have heater inspected yearly by a qualified service agency.
5.Keep inside of heater free from combustible and foreign objects.
