Gas fireplace repair and yearly service in Lawsona/Fern Creek

The glass seal plate behind the front

Some fireplaces have parts behind the glass that the owner never sees in normal use. On the Heat & Glo Supreme inserts, for example, a glass seal plate sits behind the fixed glass assembly. The manual repeats the same warning in several places. The seal plate must be properly installed, or components may run too hot and there is a risk of carbon monoxide exposure.

That plate comes out more often than people expect. On that model the barrier front, the glass and the seal plate are all removed to reach the control cavity, and the break-in cleaning in the owner's manual takes the glass off too. Each of those moments is a chance for the plate to go back crooked or be left on the floor.

Whenever the glass is off a model like this, our technician checks the seal plate for position and fit before the glass returns, and again before the unit is lit. A damaged or missing plate is priced on the estimate with the maker's replacement part.

Hot glass, children and pets around the fireplace

The glass on a gas fireplace gets hot enough to burn, and it stays hot for a while after the flame goes out. The manuals we have read warn that surfaces remain hot after shutdown and that toddlers, young children and others may be susceptible to accidental contact burns. Glass cleaning instructions from another maker also say to keep children and pets a safe distance away.

That concern runs through an insert owner's manual as well, which lists practical steps for households with small children or other at-risk people. Each one is easy to keep up.

Some remotes also have a child lock switch tucked inside the battery compartment. Before a serviced unit is lit again, the barrier's fit is checked.

• Keep the barrier in place whenever the fireplace runs
• Fit a switch lock or a remote with a child lockout
• Keep remote controls out of reach
• Never leave children alone near it, lit or cooling

Why the glass assembly is handled with care

A fixed glass assembly looks sturdy once it is latched in place, but the manuals treat it as a breakable part. The care instructions for one line say to avoid striking, scratching or slamming the glass, and they warn that scratches and nicks can lead to breakage when the glass is exposed to heat. Another maker adds that the glass is never removed while it is hot.

Removal is part of many service tasks, from cleaning to reaching the controls. The manuals describe supporting the assembly while the latches release and setting it down on a stable surface large enough to hold it. One of those manuals also notes that the glass and its gasket can carry residue that may stain carpet or flooring.

The glass comes off only once the unit has cooled, it is supported through the latch release, and its edges and gasket are looked over before it goes back. A chip found during that handling is referred for glass replacement rather than refitted.

Carbon monoxide alarms in a home with a gas fireplace

Burning gas indoors is one more reason to have working carbon monoxide alarms. The gas is colorless and has no odor, so it cannot be seen or smelled. The NFPA heating safety tip sheet says to install and maintain CO alarms, and CDC guidance calls for battery-operated or battery back-up alarms near every sleeping area.

The fireplace manuals describe what exposure can feel like. Early signs of carbon monoxide poisoning are similar to the flu, with headaches, dizziness or nausea. Some people are more affected than others, including pregnant women and people with heart or lung disease.

If a carbon monoxide alarm sounds, or those signs appear while the fireplace runs, move everyone out into fresh air and dial 911 from there. The fireplace stays off until a qualified service person has inspected it and found the cause.
