What are some common issues and solutions for the HEATILATOR CD4842R?

ISSUE SOLUTIONS
Condensation on the glass This is a result of gas combustion and temperature variations. As the appliance warms, this condensation will disappear.
Blue flames This is a result of normal operation and the flames will begin to yellow as the appliance is allowed to burn for 20 to 40 minutes.
Odor from appliance When first operated, this appliance may release an odor for the first several hours. This is caused by the curing of materials from manufacturing. Odor may also be released from finishing materials and adhesives used near the appliance. These circumstances may require additional curing related to the installation environment.
Film on the glass This is a normal result of the curing process of the paint and logs. Glass should be cleaned within 3 to 4 hours of initial burning. A non-abrasive cleaner such as gas appliance glass cleaner may be necessary.
Metallic noise Noise is caused by metal expanding and contracting as it heats up and cools down, similar to the sound produced by a furnace or heating duct. This noise does not affect the operation or longevity of the appliance.
Is it normal to see the pilot flame burn continually? In an IntelliFire ignition system (IPI), the pilot flame should turn off when the appliance is turned off. Some optional control systems available with IPI models may allow the pilot flame to remain lit. In a standing pilot system, the pilot will always stay on.

How do I troubleshoot the Standing Pilot Ignition System on my HEATILATOR CD4842R?

Symptom Possible Causes Corrective Action
1. After repeated triggering of the red or black piezo ignitor button, the spark ignitor will not light the pilot. Check for spark. A. No gas or low gas pressure. Check the remote shut-off valves from the appliance. Usually, there is a valve near the gas main. There can be more than one valve between the appliance and the main.
B. No LP in tank. Check the LP (propane) tank. You may be out of fuel.
C. Ignitor. Check the spark at the electrode and pilot. If no spark and electrode wire is properly connected, replace the ignitor. Verify that there is no short in the electrode wire.
D. Pilot or misaligned electrode (spark at electrode). Using match, light the pilot. If the pilot lights, turn off the pilot and trigger the piezo ignitor button again. If the pilot lights, an improper gas/air mixture caused the bad lighting and a longer purge period is recommended. If the pilot will not light, ensure the gap at the electrode and pilot is one-eighth inch to have a strong spark. If the gap is OK, replace the pilot.
2. The pilot will not stay lit after carefully following the lighting instructions. A. Thermocouple. Check that the pilot flame impinges on the thermocouple. Adjust the pilot for proper flame impingement. Ensure that the thermocouple connection at the gas valve is fully inserted and tight (hand tighten plus 1/4 turn). Verify proper voltage output from the thermocouple to the valve. The millivolt reading should read 8-16 millivolts. If less than 8 millivolts, replace the thermocouple.
B. Improper gas inlet pressure. Natural gas should be 5-7 in. w.c. LP should be 11-14 in. w.c. Verify pressure with a manometer.
C. Valve. If the thermocouple is producing 8-16 millivolts, replace the control valve.
3. The pilot is burning, there is no burner flame, the valve knob is in the ON position, and the ON/OFF switch is in the ON position. A. On/off switch or wires defective. Check the ON/OFF switch and wires for proper connections. Place jumper wires across the terminals at the ON/OFF switch. If the burner comes on, replace the ON/OFF switch. If the switch is OK, place the jumper wires across the ON/OFF switch wires at the gas valve. If the burner comes on, the wires are faulty or connections are bad.
B. Thermopile may not be generating sufficient millivoltage. Check that the pilot flame impinges the thermopile properly. Be sure the wire connections are tight. Check the thermopile with a millivolt meter. At the TH-TP&TP terminals, the meter should read 350 millivolts minimum. Replace the thermopile if the reading is below the minimum.
4. Frequent pilot outage problem. A. Pilot flame may be too high or too low, or blowing out. Clean the thermocouple and adjust the pilot flame for proper flame impingement. Follow lighting instructions carefully.
5. The pilot and main burner extinguish while in operation. A. No LP in tank. Check the LP (propane) tank. Refill the fuel tank.
B. Improper gas inlet pressure. Verify with a manometer. NG should read 5-14 inches w.c. LP should read 10-14 inches w.c.
C. Inner vent pipe leaking exhaust gases back into the system. Check the venting system for damage. Replace/repair improperly assembled pipe sections.
6. Glass soots. A. Flame impingement. Adjust the log set so that the flame does not excessively impinge on it. Refer to log instructions.
B. Improper air shutter setting. Refer to the manual for shutter set points. If the unit has an adjustable shutter, it may be necessary to increase the shutter opening.
C. Debris around air shutter. Inspect the opening at the base of the burner. NO MATERIAL SHOULD BE PLACED IN THIS OPENING.
7. Flame burns blue and lifts off burner. A. Insufficient oxygen being supplied. Ensure that the vent cap is installed properly and free of debris. Ensure that the vent system joints are tight and have no leaks. Ensure no debris is at the base of the air holes. Ensure the glass is tightened properly.

How do I troubleshoot the Intellifire Ignition System on my HEATILATOR CD4842R?

Symptom Possible Cause Corrective Action
1. Pilot won’t light. The ignitor/module makes noise, but no spark. A. Incorrect wiring. Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are connected to correct terminals on the module and pilot assembly.
B. Loose connections or electrical shorts in the wiring. Verify no loose connections or electrical shorts. Verify connections underneath the pilot assembly are tight and not grounding out.
C. Ignitor gap is too large. Verify the gap of the igniter to the right side of the pilot hood. The gap should be approximately .17 inch or 1/8 in. (3 mm).
D. Module. Turn the ON/OFF switch to OFF. Remove the ignitor wire “I” from the module. Place a grounded wire about 3/16 in. (5 mm) away from the “I” terminal. Turn the switch ON. If there is no spark, the module must be replaced. If there is a spark, inspect the pilot assembly for a shorted sparker wire or cracked insulator.
2. Pilot won’t light, there is no noise or spark. A. No power or power supply installed incorrectly. Verify the power supply is installed and plugged into the module. Check the voltage of the power supply under load; acceptable readings are between 3.2 and 2.8 volts AC.
B. A shorted or loose connection in wiring. Remove and reinstall the wiring harness. Verify a tight fit. Verify the pilot assembly wiring to the module. Check continuity of each wire.
C. Improper wall switch wiring. Verify that 110/VAC power is “ON” to the junction box.
D. Module not grounded. Verify the black ground wire from the module wire harness is grounded to the metal chassis of the appliance.
E. Module. Turn the ON/OFF switch to OFF. Remove the ignitor wire “I”. Turn the switch ON. If there is no spark at the “I” terminal, the module must be replaced. If there is a spark, inspect the pilot assembly for a shorted sparker wire or cracked insulator.
3. Pilot sparks, but Pilot will not light. A. Gas supply. Verify that the incoming gas line ball valve is “open”. Verify that inlet pressure reading is within acceptable limits.
B. Ignitor gap is incorrect. Verify that the spark gap from the ignitor to the pilot hood is .17 in. or 1/8 in (3 mm).
C. Module is not grounded. Verify the module is securely grounded to the metal chassis of the appliance.
D. Module voltage output / Valve/ Pilot solenoid ohms readings. Verify battery voltage is at least 2.7 volts. Replace batteries if the voltage is below 2.7.
4. Pilot lights but continues to spark, and main burner will not ignite. (Flame rectification has not occurred). A. A shorted or loose connection in flame sensing rod. Verify all connections to the wiring diagram. Verify connections underneath the pilot assembly are tight and not grounding out.
B. Poor flame rectification or contaminated flame sensing rod. With the fixed glass assembly in place, verify that the flame is engulfing the flame sensing rod on the left side of the pilot hood. The flame sensing rod should glow shortly after ignition. Verify the correct pilot orifice is installed and gas inlet is set to pressure specifications.
C. Module is not grounded. Verify the module is securely grounded to the metal chassis of the appliance. Verify that the wire harness is firmly connected to the module.
D. Damaged pilot assembly or contaminated flame sensing rod. Verify that the ceramic insulator around the flame sensing rod is not cracked, damaged, or loose. Clean the flame sensing rod with emery cloth. Verify continuity with a multimeter. Replace the pilot if any damage is detected.
E. Module. Turn the ON/OFF switch to OFF. Remove the ignitor wire “I” from the module. Turn the switch ON. If there is no spark at the “I” terminal, the module must be replaced. If there is a spark, the module is fine.
