Fog on the glass when the fireplace starts

Many owners see the glass fog up just after the burner lights and worry that something is leaking. The owner's manuals we have read explain it. Burning gas produces water vapor, and when the inside of the glass is cooler than the dew point, that vapor condenses on it. As the glass warms, the fog disappears.

One of them describes a second case. When air conditioning has cooled the glass, warm outdoor air inside the firebox can condense on it even while the fireplace is off. The manual answers it under the same normal-condensation heading.

Fog that clears on its own is normal operation, so it does not need a repair. It is worth mentioning at a service visit if it comes with something else, such as a flame that looks unusual or glass that sits loose. The glass seating and the burner are then checked together, since those are the parts the manuals connect to how the flame behaves.

The venting system gets its own yearly check

The flame gets most of the attention, but the vent carries the exhaust out of the house. One maker's direct vent and natural vent manuals both say the fireplace and venting system should be inspected before first use and at least annually by a qualified service person, and that the entire venting system should be inspected to confirm it works properly.

The seasonal venting checks in an insert owner's manual go beyond the cap. They include corrosion or separation, the seals where the vent passes through the building, a draft shield that is damaged or missing, and a screw that holds the vent collar's slide plate.

During service, our technician looks at the vent parts that can be reached at the appliance and at the cap from the ground. Anything that needs work is listed separately on the estimate as venting work for your Lake Hart home, so the burner service and the vent work stay distinct.

Keeping the space in front of the fireplace clear

Heat leaves the front of the fireplace and warms whatever is close to it. The NFPA heating safety tip sheet asks for a three-foot clear zone, at least, between heating equipment, the fireplace included, and anything that can burn. One owner's manual marks a clear space in front of its units and warns that clothing, furniture, draperies and other flammable materials must not be placed on or near the appliance.

The manuals add details that are easy to overlook. Most of them are about what ends up on or around the unit.

The louvers and openings get a look on a maintenance visit, and anything stored or hung too close is noted. For Lake Hart homeowners who have added a mantel or shelf since the fireplace went in, the maker's clearance table for that model is the reference.

• Nothing placed on top of the fireplace
• No decorations or clothing hung on or around it
• Louvers and air openings left unblocked
• Candles and heat-sensitive items kept off the mantel and hearth

Backed by our workmanship warranty

For Lake Hart homeowners, our gas fireplace repairs are backed by our workmanship warranty and by our 100% satisfaction guarantee. Before the visit ends, our technician runs the fireplace through its lighting sequence, as the manuals call for after service, and you get a written record of the work we did.

The appliance's own warranty is separate and belongs to the maker. Heat & Glo's terms, for example, set their own coverage and exclude damage from components the maker did not supply or approve and from repairs performed incorrectly. That is one more reason the parts on our estimates are the ones the maker specifies for your model.

If you have the original paperwork for the fireplace, keep it with the model and serial number, since it helps with any claim you make to the maker. We read both off the rating plate onto your estimate either way.
