Near boiler piping
Check boiler and system piping for any sign of leakage.
Continual fresh make-up water will reduce boiler life.
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 at
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
Verify ON/OFF switch and convenience plug are both
functional
CHAMBER/BURNER
Combustion Chamber
Check burner tube and combustion chamber coils. Clean
according to maintenance section of manual. Vacuum
combustion chamber. Replace any gaskets that show signs
of damage.
Spark Electrode
Clean. Set gap at .156”. See Figure 34.
Flame Probe
Clean. Check ionization in uA (d7 on status menu in Start-up
Procedures). Record high fire and low fire.
CONDENSATE
Neutralizer
Check condensate neutralizer. Replace if necessary.
Condensate trap and
hose
Ensure the condensate trap is filled with water. Disconnect
condensate hose. Clean out dirt. Fill with water to level of
outlet and re-install. (NOTE: Verify the flow of condensate,
making sure that the hose is properly connected during final
inspection.)
GAS
Pressure
Measure incoming gas pressure (3.5” to 14” W.C.)
Pressure Drop
Measure drop in pressure on light off (no more than 1” 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.
SAFETIES
ECO (Energy Cut
Out)
Check continuity on Flue and Water ECO. Replace if
corroded.
Thermistors
Check wiring. Verify through ohms reading.
FINAL INSPECTION
