Factory-built fireplaces repaired with listed parts in Signal Hill

Why only the maker's parts go in

Manuals for factory-built fireplaces are direct about parts. One maker tells owners to use only original replacement parts, and warns that using components it did not design and test for the fireplace system may cause a fire hazard.

A panel cut from generic board, a sheet metal patch or a pipe section from another brand can look close enough. We fit the listed part for your model, or explain why none is available before discussing other options.

Fuel that belongs in a factory-built fireplace

Manufacturers write their fuel rules plainly. One maker calls for solid wood only, preferably dry, well-seasoned hardwood, and warns against treated wood, charcoal, coal, trash, driftwood, plywood and other wood products made with binders.

The wrong fuel burns hotter or dirtier than the firebox was tested for, and the damage shows up as cracked panels and warped metal. When we repair a unit, we also go over what goes into it, so the new parts avoid the same fate.

• Dry, well-seasoned hardwood
• No treated wood or plywood
• No charcoal or coal
• No trash or driftwood

Cleaning a round metal flue

The inner flue of a factory-built chimney is thin stainless steel, round and smooth. One maker's troubleshooting advice for a dirty or blocked chimney mentions a properly sized chimney brush, since the brush has to fit the round pipe it cleans.

During a prefab repair we note the condition of the flue and whether deposits are present. Cleaning is scheduled with a brush that fits your flue, and dents or damage found along the way go on the repair list.

Air conditioning, fans and draft

One maker's warranty notes that it is not responsible for inadequate draft caused by air conditioning and heating systems, mechanical ventilation or construction conditions that create negative pressure in the room.

That note points to where many draft problems start. Before replacing any part for a draft complaint, we look at the fans, returns and air handling near the fireplace and explain what we find.

• Air conditioning returns
• Bath and kitchen exhaust fans
• Mechanical ventilation
• Tight construction
