Propane and natural gas fireplace repair in Bay Ridge

How the flame should look once warm

A gas flame changes as the fireplace warms. One owner's manual says blue flames at start-up are normal and begin to yellow as the fireplace keeps running. A direct vent manual from another maker describes the warmed-up flame on its models as yellow and slightly taller than the rear log, after about 15 to 30 minutes at full rate.

Those descriptions are model-specific, and the same manual notes that the type of installation, the vent layout and wind can make the pattern vary. So a flame that looks different from another fireplace is not a fault by itself. A flame that stays blue and short, one that leaves dark marks on the logs, or one that has changed from how it used to look is worth a check.

On a visit to your Bay Ridge home, the flame is watched from a cold start until fully warm and compared with what the manual for that model describes. Any gap between the two is traced to its cause and written into the estimate.

Cracked or chipped glass takes the fireplace out of use

The manuals are direct about damaged glass. One insert maker says not to operate the fireplace with the glass removed, cracked, broken or scratched, and to replace it as a complete assembly. A direct vent manual from another maker says to replace glass that is chipped, cracked or broken, and that replacement glass door assemblies must come from the fireplace maker, with no substitute materials.

The front on these units is ceramic glass fitted to a frame and gasket, not a pane cut to size at a hardware counter. The insert maker adds that its glass is ceramic, to be replaced only with ceramic glass obtained through the dealer. Until the new assembly is in, the fireplace stays off, even when the crack looks small.

Glass work belongs to our gas fireplace glass replacement service. On a repair visit, our technician confirms the damage, reads the model from the rating plate so the right assembly can be matched and looks at the burner and media for anything the manuals link to breakage. The glass then appears as a separate line routed to that service.

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

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 Bay Ridge 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
