Replacing gas logs that came with the house

A house bought with a gas log set in the fireplace often comes without its manual. Without it, nobody knows which set it is, whether the logs are in the right places or whether the damper clamp is still there. Logs from another set do not match the burner's layout, so the manual matters.

We identify the set from its rating plate, find its manual, reset the logs to it and check the clamp, pressure and flame. Where the set is past its life, a replacement is quoted. Inherited gas logs at a house in St. Nicholas? Have them checked at (904) 920-5495.

The oxygen sensing pilot on vent-free logs

Vent-free sets carry an oxygen depletion sensing pilot, which shuts the set off if the room's fresh air runs low. One maker's manual says the heater needs fresh air ventilation to run properly and points to its ventilation section if the set keeps shutting off.

Repeated shutoffs are a message about the room, not a nuisance to work around. We check the room volume, open connections and the house's tightness, and the sensing pilot is left exactly as the maker built it. The same maker notes that running above 4,500 feet of elevation can cause pilot outage. A shutoff after a long burn in a small room is the system doing its job.

Minimum firebox size for a vent-free set

Size tables for vent-free sets are separate. One maker's 18-inch set needs a firebox at least 24 inches high, 14 deep, 28 wide at the front and 20 at the rear, and its 24-inch set needs 32 and 22 inches of width.

The same manual sets clearances from the fireplace opening: 16 inches to a side wall and 42 inches from the top of the opening to the ceiling for both sizes. We measure the firebox and the wall around it together, since a set that fits the firebox can still miss the clearances. Both sets of figures go on the estimate.

Broken and chipped logs

Cracked or broken logs change the flame around them. One vent-free maker says not to run its set with a broken log or with a chip the size of a dime or larger, and another maker's vented manual says not to operate with any log broken.

Replacement logs come from the set's own parts list, placed where the originals sat. We do not mix logs from other sets, even when they look alike, because their shape and position are part of how the burner was tested. Ordering by the set's model number keeps the shapes right.

Gas log questions from St. Nicholas

What is the damper clamp for?

It fixes the damper partly open so exhaust from vented logs keeps a way out, even if someone reaches for the handle. Fitting it is part of our installation.

Is the gas log inspection free?

Yes. The measuring visit and the written estimate are free, and that price holds. Book the set within 72 hours of the measuring visit and 10% comes off the installation.
