2. Inspect burner, pilot, and primary air inlet holes on injector holder for dust and dirt (see Figure 37). 3. Blow air through the ports/slots and holes in the burner. 4. Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle. 5. Blow air into the primary air holes on the injector holder. 6. In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4. Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 38). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

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. Remove blockage. Blocked burner flame holes will create soot.

OBSERVED PROBLEM WARNING: Turn off heater and let cool before servicing. Only a qualified service person should service and repair heater. POSSIBLE CAUSE CAUTION: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage ODS/ pilot unit. REMEDY When ignitor button is pressed, there is no 1. Ignitor electrode not connected to ig1. Reconnect ignitor cable spark at ODS/pilot nitor cable 2. Ignitor cable pinched or wet 2. Free ignitor cable if pinched by any metal or tubing. Keep ignitor cable dry 3. Broken ignitor cable 3. Replace ignitor cable 4. Bad piezo ignitor 4. Replace piezo ignitor 5. Ignitor electrode broken 5. Replace pilot assembly 6. Ignitor electrode positioned wrong 6. Replace pilot assembly When ignitor button is pressed, there is spark at ODS/pilot but no ignition 1. Gas supply turned off or equipment shutoff valve closed 1. Turn on gas supply or open equipment shutoff valve 2. Control knob not in PILOT position 2. Turn control knob to PILOT position 3. Control knob not pressed in while in 3. Press in control knob while in PILOT PILOT position position 4. Air in gas lines when installed 4. Continue holding down control knob. Repeat igniting operation until air is removed 5. ODS/pilot is clogged 5. Clean ODS/pilot (see Cleaning and Maintenance, page 18) or replace ODS/ pilot assembly 6. Gas regulator setting is not correct 6. Replace gas control 7. Depleted gas supply (propane/LP only) 7. Contact local propane/LP gas company ODS/pilot lights but flame goes out when control knob is released 1. Control knob not fully pressed in 2. Control knob not pressed in long enough 1. Press in control knob fully 2. After ODS/pilot lights, keep control knob pressed in 30 seconds 3. Equipment shutoff valve not fully open 3. Fully open equipment shutoff valve 4. Pilot flame not touching thermocouple, 4. A) Contact local propane/LP or natural which allows thermocouple to cool, causgas company ing pilot flame to go out.This problem could be caused by one or both of the following: B) Clean ODS/pilot (see Cleaning and A) Low gas pressure Maintenance, page 18) or replace ODS/ B) Dirty or partially clogged ODS/pilot pilot assembly 5. Thermocouple connection loose at con5. Hand tighten until snug, then tighten trol valve 1/4 turn more 6. Thermocouple damaged 6. Replace pilot assembly 7. Control valve damaged 7. Replace control valve Burner does not light after ODS/pilot is lit 1. Burner orifice clogged 1. Clean burner (see Cleaning and Maintenance, page 18) or replace burner orifice 2. Inlet gas pressure is too low 2. Contact local propane/LP or natural gas company 3. Burner orifice diameter is too small 3. Replace burner orifice 4. Thermopile leads disconnected or im4. Reconnect leads (see Wiring Diagram, properly connected page 32) 5. Burners will not come on in remote position 5.
