Symptom field notes
Smoke entering the room
Smoke indoors is a reason to stop using the appliance and arrange qualified assessment. If there is an active fire, alarm or immediate danger, leave and contact emergency services.
Do not light another fire to reproduce the problem for a photo.
What to document
- Which appliance was operating?
- Did the symptom begin at startup or later?
- Did a renovation, appliance change or ventilation change precede it?
Keep dates and observations separate from guesses about the cause. Photographs from a safe location and earlier service records are useful starting material.
What to ask the contractor
- What parts of the appliance and venting system will you evaluate?
- What evidence would distinguish an obstruction from a draft or pressure issue?
- What must be addressed before further use?
Ask for findings, access limitations and recommended next steps in writing. A proposed product or repair method should follow an explanation of the observed condition.
Turn the observation into a comparable scope
Send the same brief to each company. Ask whether the appointment is an inspection, a diagnostic visit or a repair, and how additional work is approved. If proposals disagree, compare the evidence each contractor cites before comparing totals.
