Near appliance
piping
Check appliance and system piping for any sign of leakage. Leaking
pipes could cause property damage. Make sure all piping is properly
supported. Flush tankless heat exchanger annually (more in hard water
conditions). See User’s Information manual for instructions.
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 (central heat, water heating, Safeties)
Temperatures Verify safe settings on appliance 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 Ensure 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.
Spark Electrode Clean. Set gap at 1/8”.
CONDENSATE
Condensate Trap Clean debris from the condensate trap. Fill with clean water.
Neutralizer Check condensate neutralizer. Replace if necessary.
Condensate hose Disconnect condensate hose. Clean out dirt and re-install. (NOTE:
Verify the ow of condensate, making sure that the hose is properly
connected during nal inspection.)
GAS
Pressure Measure incoming gas pressure (3.5” to 14” W.C.)
Pressure Drop Measure drop in pressure on light o (no more than 1” W.C.)
Check for leaks Check gas piping for leaks. Verify that all are properly supported.
COMBUSTION
CO/CO2 Levels Check CO and CO2 levels in Exhaust. Record at high and low re.
SAFETIES
ECO (Energy Cut Out) Check continuity on Flue and Water ECO. Replace if corroded.
CH AND DHW LOOPS
It is recommended to ush the CH and DHW heat exchangers annually
if water hardness exceeds 12 grains per gallon (considered extremely
hard water). If water hardness falls below 12 grains per gallon it is
recommended to ush the heat exchanger every two to three years.
It is also recommended to clean the CH and DHW inlet lters annually.
FINAL INSPECTION
Check list Verify that you have completed entire check list. WARNING: FAILURE TO
DO SO COULD RESULT IN SERIOUS INJURY OR DEATH.
