Control module fault codes and lights

Electronic controls on the models we have read report their own faults with a light and sometimes a beep. Heat & Glo's IntelliFire Touch module, for example, blinks a red and green code with a beep when it locks out.

Each maker prints its own chart, so a code is read only against the chart for that exact control. A code also narrows the fault without finishing the job, since a spark fail still needs the wire, electrode and module checked.

Our technician notes the code at your Stone Crest home, confirms the cause behind it and lists that cause on the estimate. One maker's command center flashes its LED in a different pattern for faults such as these.

• Spark fail
• No sensor signal
• Pilot lockout after a failed trial or a lost flame
• Low battery or low thermopile power

A burner that has shifted out of line

The pilot lights the main burner across a small gap, so the two have to sit where the maker put them. The burner section of one yearly checklist opens by asking the technician to verify that the burner is secured and aligned with the pilot or igniter.

A burner can be disturbed whenever the logs and base pan above it are lifted out for service or cleaning, and it has to go back exactly as it came out. Next on that checklist come smooth lighting, carryover to all ports and no ignition delay, so alignment is confirmed before a slow or patchy start is blamed on another part.

Our technician checks the burner's mounting and its line to the pilot, then watches several starts of the fireplace in your Stone Crest home. Where alignment was the cause, correcting it is part of the repair, and missing fixings or a damaged burner are listed on the estimate.

Exhaust odor or a B-vent burner that goes out

A B-vent, or natural vent, fireplace relies on a draft hood and a vent that draws well. When the pilot and main burner both drop out while running, the troubleshooting table in a Vermont Castings Group natural vent manual names three causes, a leaking inner vent pipe that sends exhaust back into the system, a horizontal run sloped the wrong way, and a vent cap that is blocked or was put on wrong.

Exhaust that is not leaving the home properly can carry carbon monoxide. If a CO alarm sounds, or anyone feels unwell while the fireplace runs, get everyone outside to fresh air and call 911 from there. Leave the fireplace off until it has been inspected.

Vent faults belong to our gas fireplace venting service. On a repair call, our technician confirms whether a shutdown traces to the vent or to the pilot and valve, so each fault is sent to the right place.

Freestanding gas stoves and fireplace heaters

Not every gas appliance with a flame behind glass is a built-in fireplace. Freestanding gas stoves, inserts and wall units are often heaters as much as decorative fireplaces, and the state's fuel gas code treats them that way. Vented gas fireplace heaters, vented room heaters and wall furnaces each have their own listing standard in that code, and each is installed per the manufacturer's instructions.

The listing shows on the rating plate. Heat & Glo's Supreme inserts, for example, are listed as vented gas fireplace heaters rather than decorative fireplaces. Service follows the same order as on any fireplace, the plate first, then the maker's manual and the parts it names.

Units without a vent are different appliances under different rules, and they go to our ventless gas fireplace service. For vented stoves and heaters in your Stone Crest home, our technician handles the pilot, burner, controls and fan as on a fireplace, and the estimate names the listing with the model.
