OPERATION

WARNING: 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 exten- sion cord. Extension cord must be at least six feet long. Exten- sion 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, 3-hole, grounded outlet. Motor will start. Fan will turn, forcing air out front of heater.

5.Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on propane tank may stop gas flow. If this happens, close propane supply valve and open again slowly.

WARNING: Be sure motor and fan are running before pushingin automaticcontrol valvebutton. Flames could flash outside heater if motor and fan are not running.

6.Turn control knob to the low position and push in (see Figure 8 and 9, page 6). Hold knob in and push piezo ignitor button. You may need to push piezo ignitor button 3-8 times until the main burner lights. When main burner lights, keep automatic control valve knob pushed in. Release button after 30 seconds.

Note: If main burner fails to light, hose may have air in it. If so, keep control knob pressed and wait 20 seconds. Release control knob and wait 20 seconds for unburned fuel to exit heater. Repeat step 6.
