Gas fireplace repair and yearly service in Haralson Estates

The vertical restrictor and erratic flames

An insert owner's manual lists long vertical vent runs as a reason for erratic flames and says a restrictor may be needed. The installation manual sets how many restrictor openings are opened by the height of the vertical vent, and notes that opening them helps with cold start and sooting problems.

The owner manual's FAQ gives a cause worth ruling out first, a glass assembly that is not correctly installed with all four latches engaged. After that, the yearly checklist asks the technician to verify the restrictor setting against the installation manual.

We confirm the vertical vent length, compare the restrictor with the manual's table and check that the glass is latched. A restrictor change is a small adjustment when the manual calls for it and goes on the estimate with the vent length that justified it, while faults in the vent pipe itself are passed to our venting team.

Gas log sets in a wood-burning fireplace

A gas log set sits in a fireplace that was built to burn wood, and Florida's fuel gas code treats it as a decorative appliance. It is listed to ANSI Z21.60 and installed by the maker's instructions. Apart from manually lighted natural gas sets listed to ANSI Z21.84, a set must light its main burner with a pilot, an ignitor or a direct ignition device and carry a flame safeguard that cuts the gas if ignition fails.

That makes a log set repair a matter of the set's own burner, pilot and safeguard, checked against its maker's manual and label much like any vented gas fireplace. The code allows these sets only in approved solid fuel-burning fireplaces, so the fireplace around the set is part of the picture too.

Existing log sets are repaired here, starting with the label, the ignition type and the safeguard. If a set is beyond repair or you want a new one, that work goes to our gas log installation service and appears as a separate option on your estimate.

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

A gas fireplace that has been under water

Water and gas controls do not mix. The manuals we have read agree on this. An appliance with any part that has been under water stays off until a qualified service technician has inspected it and replaced each part of the control system and each gas control that got wet. That holds even when the unit looks clean and dry afterward.

One natural vent manual goes further and calls for arranging replacement of the unit. Another simply tells owners to keep the appliance dry, because water may damage controls. The state fuel gas code also sets rules for where appliances sit in flood hazard areas, which matters if the fireplace is replaced.

We read the model from the rating plate, find that model's instructions and list every control part the maker calls for, or the replacement option where the manual requires it. The fireplace is not lit until that work is done.
