If needed, keep pressing ignitor button until pilot lights. Note:If pilot does not light, contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure on page 16. 7. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Note: If pilot goes out, repeat steps 3 through 7. • If control knob does not pop out when released, contact a qualified service person or gas supplier for repairs. 8. Slightly depress and turn control knob counterclockwise to the HIGH position. The burner should light. Set control knob to any heat level between HIGH and LO.

Even the lowest setting provides realistic, dancing yellow flames. Selecting higher settings produces greater heat output. This results in increased heating comfort. TO TURN OFF GAS TO APPLIANCE CAUTION: Do not try to adjust heating levels by using the manual shutoff valve. Shutting Off Heater 1. Press in and turn control knob clockwise to the HIGH position. 2. Turn the control knob clockwise to the PILOT position. 3. Press in control knob and turn clockwise to the OFF Position. Shutting Off Burners Only (pilot stays lit) 1. Turn the control knob clockwise to the HIGH position. 2. Press in and turn control knob clockwise to the PILOT position. MANUAL LIGHTING PROCEDURE 1. Follow steps 1 through 5 under Lighting Instructions, page 15. 2. Depress control knob and light pilot with match. 3. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8, page 15. INSPECTING BURNERS Check pilot flame pattern and burner flame patterns often. PILOT FLAME PATTERN Figure 20 shows a correct pilot flame pattern. Figure 21 shows an incorrect pilot flame pattern. (Note: Appearance of pilot assembly may vary by model.) The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 21 • turn heater off (see To Turn Off Gas to Appliance, column 1) • see Troubleshooting, pages 17 through 19 Thermocouple Pilot Burner Pilot BurnerThermocouple Figure 20 - Correct Pilot Flame Pattern Figure 21 - Incorrect Pilot Flame Pattern BURNER PRIMARY AIR HOLES Air is drawn into the burner through the holes in the fitting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot. MAIN BURNER Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with yellow flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Either remove blockage or replace burner. Blocked burner flame holes will create soot. 16 OWNER’S MANUAL TROUBLESHOOTING Note: For additional help, visit DESA International’s Technical Service web site at Note: All troubleshooting items are listed in order of operation. OBSERVED PROBLEM When ignitor button is pressed, there is no spark at ODS/pilot WARNING: Turn off and un- plug heater and let cool before servicing. Only a qualified ser- vice person should service and repair heater. POSSIBLE CAUSE 1. Ignitor electrode not connected to ignitor cable 2. Ignitor cable pinched or wet 3. Piezo ignitor nut is loose 4. Broken ignitor cable 5. Bad piezo ignitor 6. Ignitor electrode positioned wrong 7. Ignitor electrode broken CAUTION: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage ODS/ pilot unit. REMEDY 1. Reconnect ignitor cable 2. Free ignitor cable if pinched by any metal or tubing. Keep ignitor cable dry 3. Tighten nut holding piezo ignitor to base panel of log set. Nut is located behind base panel. 4. Replace ignitor cable 5. Replace piezo ignitor 6. Replace ignitor 7. Replace ignitor When ignitor button is pressed, there is spark at ODS/pilot but no ignition 1. Gas supply turned off or manual shutoff valve closed 2. Control knob not in PILOT position 3. Control knob not pressed in while in PILOT position 4. Air in gas lines when installed 5. ODS/pilot is clogged 6. Gas regulator setting is not correct 1. Turn on gas supply or open manual shutoff valve 2. Turn control knob to PILOT pos...
