To clean these parts we recommend using compressed air no greater than 30 psig. This can be done by using a vacuum cleaner in the blow position, using compressed air in a can, please follow the directions on the can. If you don’t follow directions on the can you could damage the burner or pilot assembly. In addition, the directions that follow should also be followed. 1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes. 2. Inspect burner and pilot for dust and dirt. 3. Blow air through the port/slots and holes in the burner. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. To clean the pilot assembly find the small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see figure 25). 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. Figure 25 CLEANING HEATER CABINET Air passageways • Use a vacuum cleaner or pressurized air to clean Exterior • Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust. TROUBLESHOOTING NOTE: All troubleshooting items are listed in order of operation and likely occurrence. WARNING: Only a qualified service person should service and repair heater. CAUTION: Never use a wire needle, or similar object to clean ODS/pilot. This can damage ODS/pilot unit. Make sure grille guard is in place before running heater. If screen or grille guard is removed for servicing it must be replaced prior to operating the heater. OBSERVED SYMPTOMPOSSIBLE CAUSEREMEDY 1. Ignitor electrode positioned wrong. 2. ignitor electrode is broken. 3. Ignitor electrode not connected to ignitor. 4. Ignitor cable pinched or wet. 5. Broken ignitor cable. 6. Bad Piezo ignitor. 7. Low Battery. 1. Gas supply turned off or equipment shutoff valve closed. 2. Control knob not fully pressed in while pressing ignition button. 3. Air in gas line when installed. 4. ODS/pilot is clogged. 5. Gas regulator setting is not correct 6. Control knob not in pilot position 1. Control knob not fully pressed in. 2. Control knob not pressed in long enough 3. Equipment shutoff valve not fully open 4. Thermocouple connection loose at control valve 5. Pilot flame not touching thermocouple, which allows thermocouple to cool, causing pilot flame to go out. This problem could be caused by one or both of the following: a. Low gas pressure b. Dirty or partially clogged ODS/pilot 6. Thermocouple damaged 7. Control valve damaged 1. Burner orifice is clogged 2. Burner orifice diameter to small 3. Inlet gas pressure is too low 1. Manifold pressure is too low 2. Burner orifice is clogged When ignitor button is pressed in, there is no spark at pilot 1. Reposition electrode 2. Replace electrode 3. Reconnect ignitor cable 4. Free ignitor cable if pinched by any metal or tubing. Keep ignitor cable dry. 5. Replace ignitor cable 6. Replace control valve (Piezo is part of control valve on 10K units). 7. Replace battery 1. Turn on gas supply turn off or open equipment shutoff valve closed 2. Fully press in control knob while pressing ignition button 3. Continue holding down control knob. Repeat ignition operation until air is removed. 4. Clean ODS/pilot (see Cleaning and Maintenance page 13). 5. Replace gas regulator 6. Turn Control knob to pilot position 1. Press in control knob fully 2. After ODS/pilot lights, keep control knob pressed in for 30 seconds 3. Fully open equipment shutoff valve 4. Hand tighten thermocouple nut until snug, and then tighten 1/4 turn more. 5. - a. Contact local gas company b. Clean ODS/pilot (see Cleaning and Maintenance, page ?). 6. Replace thermocouple 7. Replace Control valve. 1. Clean burner orifice (see Cleaning and Maintenance on page 13), or replace burner orifice 2. Replace burner orifice 3. Contact local gas company 1. Contact local gas company 2. Clean burner orifice (see Cleaning and Maintenance on page 13), or replace burner orifice ODS/pilot lights but flame goes out when control knob is released When ignitor button is pressed in, there is a spark at the ODS/ pilot but no ignition Burner does not light after ODS/pilot is lit Delayed ignition of burner TROUBLESHOOTING WARNING: If you smell gas: • Shut off gas supply • Do not try to light any appliance • Do not touch any electrical switch; do not use any phone in your building • Immediately call you gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. • If you cannot reach your gas supplier, call the fire department. IMPORTANT: Operating heater where impurities in air exist may create odors. Cleaning supplies, paint, paint remover, cigarette smoke, cements and glues, new carpet or textiles, etc., create fumes. These fumes may mix with combustion air and create odors and possible discoloration of walls and ceilings.
