Periodically check the unit's condition and eliminate any potential cause of premature deterioration. Fireplace inserts and freestanding stoves have specific installation requirements based on manufacturer's recommendations, unit design, and local regulations. Due to the variability of these requirements, it is not possible to properly evaluate these units as part of a standard home inspection. Special attention should be paid to providing adequate flue and unit clearances from combustibles and maintenance of an approved and properly installed flue. Obtain additional information from the manufacturer and local authorities on units present.
Dampers can warp or become damaged with usage, or, in some cases, be lacking.
Smoke chambers and flues are generally lined with a smooth heat resistant material to prevent damage to the chimney interior or leakage of combustion products and to facilitate cleaning. If deterioration exists or if heavy usage of the unit is anticipated, a company specializing in this type of work should be contacted. Birds and animals often nest in seldom-used chimney flue pipes. Creosote residue accumulates on relatively cool chimney linings, and, when ignited, causes an extremely dangerous fire. Never burn trash, coal, charcoal or polystyrene packaging materials in a fireplace.
