Operation

Review and understand the

warnings in the Safety Information section, pages 2 and 3. 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 three- prong, grounded extension cord. Extension cord must be at least six feet long. Extension cord must be UL listed.

EXTENSION CORD WIRE SIZE

REQUIREMENTS

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 position. Turn thermostat control knob slowly clockwise until electric motor and fan begin to run. Heater will start in approximately 3 seconds. Adjust thermostat control knob to WARMER or COOLER setting as needed.

NOTE: If heater does not start after 3 seconds, the ignition control will automati- cally 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 seconds 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 operation, heater will cycle off when air temperature rises to thermostat 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 natural gas supply valve.

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.
