Appliance / Fuel Change Review

Change the fuel or the appliance and the code asks for a Level 2 inspection — wood to gas, an open fireplace taking an insert, a new stove on an old flue. The reason is simple: a flue that was correct for the previous appliance is frequently wrong for the next one. Sizing changes with input rating, the liner material has to suit the new fuel’s condensate, and clearances and connector runs get re-measured against the new appliance’s listing. We camera-scan the flue, compare it against the manufacturer’s requirements, and hand you a variance list — each item naming the requirement, the measured condition, and what closing the gap costs. Do it before the appliance is bought, not after.

FAQ

Common questions about appliance / fuel change review.

What's the difference between Level 1, 2, and 3 chimney inspections?

They're tiers of access, defined in NFPA 211. Level 1 covers readily accessible areas — the routine annual check when nothing has changed. Level 2 adds a camera scan of the flue interior plus attics and crawl spaces, and it's required at property sale, after a fire, or when the appliance or fuel changes. Level 3 involves removing components or finish materials to reach a suspected hidden hazard. Each tier has to be justified by the one below it.

When is a Level 2 inspection actually required?

NFPA 211 names the triggers: sale or transfer of the property, after a chimney fire or operating malfunction, after external events like storms or seismic activity, and whenever you change the fuel type or connect a new appliance. If any of those apply, a Level 1 isn't sufficient — the standard wants the flue interior scanned, not just eyeballed from the top and bottom.

What do I actually get after an inspection?

A written report, standard turnaround 48 hours. It lists every checkpoint with a pass or fail verdict, a photo behind each finding, the relevant code or standard reference, and — when something fails — what correcting it involves. It's a document you can forward to an insurer, a buyer, or another contractor for a competing bid. Nothing we say on-site counts until it's in the report.

How often does a chimney really need sweeping?

The honest answer is: when measurement says so. NFPA 211 requires annual inspection, but sweeping is triggered by creosote depth — 1/8 inch is the threshold. A fireplace burning most nights all season usually hits that in about a year. Occasional weekend fires might take two or three. We measure at each inspection and only recommend a sweep the measurement supports.

My home inspector already looked at the chimney. Isn't that enough?

General home inspectors do visual checks from the ground and the firebox — their own standards of practice put chimney flue interiors outside scope. The failures that cost real money, like gapped flue tiles and hidden cracking, only show on a camera scan. That's why NFPA 211 specifies a Level 2 at property transfer. Plenty of chimneys pass; the point is knowing before you close, not after.
