Gas log installation done by the manual in Signal Hill

When the damper clamp does not fit

Not every damper blade takes the supplied clamp. For that case, one maker gives three ways out, a permanent stop, taking the damper blade out altogether or cutting the damper back until it leaves the minimum opening in its table.

Each option has tradeoffs for how the fireplace behaves when the set is off. Our specialists explain them at your home, recommend the one that fits your damper and list it on the estimate with upfront pricing.

A vented set in a bedroom fireplace

Vented sets follow a different exception. An exception in section 303.3 of Florida's fuel gas code allows decorative appliances for installation in vented solid fuel-burning fireplaces in sleeping rooms when the room meets the volume criteria of section 304.5.

That makes the room's size part of the job. Our pros measure the bedroom and any spaces that open into it, check the result against the code and put the finding in writing before recommending a vented set.

Supply pressure the burner needs

A burner needs gas at the right pressure to light and run properly. One maker wants at least 5 inches of water column at the inlet on natural gas and at least 11 on propane, with ceilings of 10.5 and 13.

The same manual says not to install the set if the minimum pressure is not available, since low pressure affects the pilot. Our technicians measure the pressure at the set with the burner running and note the reading in your record.

The first light, done by the manual

The first time a new set is lit, our technician follows the lighting instructions printed for that set, step by step, with you watching. Each control has its own sequence, and doing it once together makes the next time easy.

We then let the set run, watch the pilot and the main burner, check for flames reaching toward the screen and confirm the shutdown works. Any adjustment the manual allows is made before we leave.

What the written gas log estimate lists

Our estimate names the log set by maker and model, the burner size, the damper clamp or stop, the media and embers and the controls. Repairs, removal of the old set and any gas piping by others each get their own line.

What you approve is what you pay, unless you agree to extra work. No fees hide in the fine print, and when you book within 72 hours after the inspection, 10% off is printed on it.
