INSPECTION ACTIVITIES
PIPING
Near heater piping Check heater and system piping for any sign of
leakage; make sure they are properly supported.
Vent Check condition of all vent pipes and joints. Check for
any obstructions on intake and exhaust termination
points. Check clearances (see Venting Section for
further details).
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 heater or Anti-Scald Valve
Temperatures Verify programmed temperature settings
ELECTRICAL
Connections Check wire connections. Make sure they are tight.
Smoke and CO Verify devices are installed and working properly.
detector 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. If dirty, clean with compressed air.
Clean chamber with vacuum.
Spark Electrode Clean. Set gap at ¼". For natural, ¼" between probes.
For LP, a ¼" gap from single probe to burner.
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.

W.C.)
Check gas pipe for Check piping for leaks. Verify that all are properly
leaks 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.
/ Low cut-off)
Thermistors Check wiring. Verify through ohms reading.
