Refractory panels and prefab fireplace parts replaced in Lake Formosa

Glass doors on a factory-built fireplace

Glass doors on a factory-built fireplace have to suit that fireplace. Section R1004.5 of the residential code says a gasketed fireplace door shall not be installed on a factory-built fireplace unless the fireplace system has been specifically tested, listed and labeled for that use under UL 127.

One maker offers its own door models for each size of fireplace. Before recommending any door repair or replacement, we identify what the listing allows, since a door that fits the opening may still be a door the fireplace was never tested with.

How often a factory-built chimney should be checked

NFPA 211 expects a yearly inspection of every chimney, fireplace and vent. One maker goes further for its wood-burning fireplaces, saying the chimney should be inspected at least twice a year during the heating season to see when deposits have built up.

The same maker says deposits of 1/8 inch or more should be removed. Cleaning is booked as its own service when it is due, and the repair visit notes what the flue looks like.

When the owner's manual is missing

Manuals go missing when homes change hands. Fireplace makers such as Heat & Glo keep manual libraries online, searchable by model, and the rating plate gives the model name to search for.

We look up the manual for your unit when the plate is readable and bring the relevant pages to the repair. You get a copy of what we used, so the next service visit starts from the same document.

• Model read from the rating plate
• Manual found in the maker's library
• Relevant pages brought to the repair
• A copy left with you

Same-day prefab visits

Same-day service is available when the schedule allows, which helps when a cracked panel or a stuck damper turns up just before you planned a fire.

A same-day visit covers the inspection and the written estimate. Parts for a factory-built fireplace usually come from the maker, so the repair itself is booked once they arrive.

• Inspection and written estimate the same day
• Parts ordered from the maker
• Repair booked when the parts arrive
