Safety boundary: Use manufacturer instructions and qualified service; each appliance type has different hazards.
Gas
Inspect the glass and gasket, keep vents clear, replace remote batteries and arrange service for soot, odour, delayed ignition or pilot problems.
Electric
Vacuum accessible air inlets with power disconnected, inspect cords and plugs and keep fabric or furniture away from heat outlets.
Wood
Arrange chimney and appliance inspection, check doors and gaskets and store dry wood safely away from the appliance.
Shared habits
Keep children and combustibles away from hot surfaces, maintain alarms and retain model and service records.
Useful questions to record
- What appliance type and venting arrangement is installed?
- Does the issue involve controls, ignition, soot, odour or glass?
- Has the unit been inspected recently?
