Signs the cap install can't wait
The most reliable early warnings on St. Catharines homes: smell changes near the appliance, staining above the firebox or on interior ceilings, unusual soot at the cap, and any water inside the smoke chamber. Any one of these is a call — two together is a stop-use.
The 90-second self-check
Look at the cap for gap or crushing, walk the crown for hairline cracks (68 freeze-thaw days a year here will find any weakness), and shine a light up the flue for glazing. Photograph anything unclear and text it over.
When to stop using the appliance
Any active water ingress, visible flame licking outside the firebox opening, or the smell of gas products in the room means shut down and call. Insurance coverage on damage during "known unsafe operation" is thin.
