Leaking pipes could cause property damage. Make sure
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.

CHAMBER/BURNER
Combustion Chamber
Check burner tube and combustion chamber coils. Clean
according to maintenance section of manual. Vacuum
combustion chamber.

W.C.)
Check gas pipe for
leaks Check piping for leaks. Verify that all are properly
supported.
COMBUSTION
CO/CO2 Levels
Check CO and CO2 levels in Exhaust (See Start-up
Procedures for ranges). Record at high and low fire.
