Propane and natural gas fireplace repair in Meridian Park

The flame safeguard shuts the gas off on purpose

The fuel gas code requires vented gas fireplaces, fireplace heaters and log sets other than the manually lighted kind to carry a flame safeguard device. Its job is narrow. When the means of lighting the main burner stops working, it shuts off the gas to that burner automatically.

So a fireplace that shuts down after its pilot fails may be doing exactly what it was built to do. On a standing pilot, the thermocouple and the pilot safety in the valve do this job, while on an electronic pilot the flame sensing rod and the module do it. Another maker's wiring page warns that incorrect wiring can override the safety lockout on its electronic pilot and may cause an explosion.

The repair is to find why the pilot or its sensing failed, and that cause is what goes on the estimate. We do not jump or bypass a safeguard to get a flame going in your Meridian Park home. The code asks for repairs that keep the listing, and one maker counts modification of the appliance among the actions that void its warranty.

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 Meridian Park 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

White film on the glass after the first burns

A cloudy white film on the inside of the glass is expected on a new fireplace. One maker calls it a normal result of the paint and logs curing and says to clean the glass within the first few hours of burning to remove the oily deposits. Another maker wants the inside of the glass cleaned after the first long burn and then as needed.

Both makers call for a non-abrasive cleaner and glass that has fully cooled. The direct vent manual describes a nontoxic, non-corrosive, mild cleaning solution wiped off with a damp cloth. Household scouring products are the wrong tool for ceramic glass.

What matters on a repair or service call is what the deposit says. A light white film is ordinary use. A dark deposit is a different finding, because the manuals trace sooting glass to flame striking the logs, and that sends the visit to the burner and log setup, written on the estimate as such.

Lint and pet hair in the air passages

Warm air leaves a gas fireplace through passages around the firebox, often pushed by a fan. The manuals say control compartments, burners and circulating air passages must be kept clean, and that more frequent cleaning may be needed where there is excessive lint and dust from carpeting, bedding material or pet hair.

Lint gathers where air is drawn in and around the burner injector. The cleaning section of a direct vent manual has the area around the injector checked and any lint or foreign material removed with a brush or vacuum. Verifying unobstructed air circulation is also on the yearly technician list in one owner's manual.

A fireplace next to carpet, a pet bed or a busy sofa can need this sooner than the calendar suggests. On a service visit in Meridian Park, our technician turns off the gas and power, vacuums the reachable passages and the burner area, and tells you whether the amount of lint points to shorter service intervals.
