INSTALLATIONOPERATION

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.

WARNING: Test all gas piping and connections for leaks after installing 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.

1.Provide natural gas supply system.

2.Install plumbing to a low pressure natural gas source. The source must be regulated to a maximum 1/2 psi. The plumbing must be a minimum 3/4 inch i.d. hose or flexible connector not over 10 feet long.

3.Connect the hose to the heater at the 1/2 inch SAE flare fitting at the inlet.

4.Open natural gas supply valve slowly.

5.Check all connections for leaks.

6.Close natural gas supply valve.

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 three-prong, grounded exten- sion cord. Extension cord must be at least six feet long. Exten- sion cord must be UL listed.

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.

4.Plug extension cord into a 120 volt/60 hertz, three-hole, grounded outlet.

5.Open natural gas supply valve 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.

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.
