Preserve the useful detail
Record model and serial, fuel or power, error code, affected fixtures, temperature behavior, first wet point, and recent service.
The decision on display
Do not transfer the hazard
Keep away from gas odor, combustion concern, hot discharge, wet electricity, and a leaking vessel. Use official safety channels.
Make the proposed work comparable
Separate diagnosis, component repair, replacement, gas or electrical work, venting, pan, expansion, permit, test, removal, and instructions.
