Refractory panels and prefab fireplace parts replaced in Spring Lake

Clearances between the unit and the framing

Zero clearance describes a design, and the design still has clearances. One maker's model lists minimum clearances to combustibles at the back and sides of the fireplace, to the ceiling, in front of the opening and to the outer pipe of the chimney.

Remodels sometimes push framing, backer board or trim tighter than those figures. We compare what we can see with the manual for your model and list any clearance that needs correcting.

• Back and sides of the unit
• Ceiling above it
• Floor space in front of the opening
• Outer pipe of the chimney

Outside combustion air kits

Outside air reaches some factory-built fireplaces through a kit fitted during framing. One maker offers kits that draw air from a vented crawl space or through a sidewall, and warns that combustion air inlet ducts shall not end in an attic.

Crushed ducts, missing screens and closed inlets change how the fireplace burns. We check the kit where it can be reached and repair it with the maker's parts.

• Duct intact from inlet to fireplace
• Screen on the outside inlet
• Inlet clear and open
• No duct ending in the attic

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.

Parts for older and discontinued models

Factory-built fireplaces outlive their production runs. One maker states that it provides replacement parts, where practicable and if available, for a set period after the last date of manufacture of a model, which means some older parts do run out.

We check availability before scheduling the work, so your fireplace is opened only when the parts are in hand. When a part is gone for good, we explain the options, including replacing the fireplace as a separate installation.
