all piping is properly supported.
Vent
Check condition of all vent pipes and joints. Ensure all
vent piping is properly supported. Check for obstructions
exhaust and intake termination points.
Gas
Check Gas piping, test for leaks and signs of aging. Make
sure all pipes are properly supported.
SYSTEM
Visual
Do a full visual inspection of all system components.
Functional
Test all functions of the system (Heat, Safeties)
Temperatures
Verify safe settings on boiler or Anti-Scald Valve
Temperatures
Verify programmed temperature settings
ELECTRICAL
Connections
Check wire connections. Make sure they are tight.
Smoke and CO
detector
Verify devices are installed and working properly. Change
batteries if necessary.
Circuit Breakers
Check to see that the circuit breaker is clearly labeled.
Exercise circuit breaker.
Switch and Plug
