Metal fireplace and chimney repair in Catalina

Offsets and elbows in the chimney

Factory-built chimneys can jog sideways with elbows, within limits. Section R1005.7 keeps every piece of a factory-built chimney within 30 degrees of vertical and allows four elbows at most in the run.

One maker's manual adds its own rules for the length of angled pipe between supports and for the straps that carry the weight above an offset. When a chimney has been rerouted, we check it against both before any repair.

Louvers and air slots stay open

Heat-circulating factory-built fireplaces move room air through channels around the firebox, drawing it in and sending it back through louvers or slots on the face. Those openings are part of the tested design.

Paint, facing material and furniture sometimes close them off. We check that every louver is clear and that nothing has been added in front of the openings the model depends on.

• Paint over the slots
• Facing material across the openings
• Furniture pushed against the grilles

Where the pipe passes through the roof

Where a metal chimney leaves the roof, a sloped metal cone is worked into the shingles and a storm collar wraps the pipe above it. One maker's manual calls for waterproof caulk around the collar's perimeter to seal it against the pipe.

The same manual warns against sealing the openings built into the rooftop cone. Split caulk, a collar that has slid down and a cone pulled loose by roof work are the leak points we find there, and each is repaired with listed parts.

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.
