of the display and indicators is recommended.
Periodic maintenance should be performed once a year by a
qualified service technician to assure that all the equipment
is operating safely and efficiently. The owner should make
necessary arrangements with a qualified heating contractor for
periodic maintenance of the heater. Installer must also inform
the owner that the lack of proper care and maintenance of the
heater may result in a hazardous condition.
It is extremely important that whenever work is performed on
the plumbing system that either:
• The water heater is powered off, or,
• The water heater is valved off and isolated from the
plumbing system.
Failure to take these measures could result in a dry-firing
condition.
Piping
Check heater and system piping for any sign of leakage; make sure
Near heater piping
pipes are properly supported.
Check condition of all vent pipes and joints. Ensure the vent piping
Vent
terminations are free of obstructions and blockages.
Check gas piping. Test for leaks and signs of aging. Make sure all pipes
Gas
are properly supported.
System
Visual Do a full visual inspection of all system components.
Functional Test all functions of the system (Heat, Safeties).
Verify safe settings on heater or anti-scald valve.
Temperatures
Verify programmed temperature settings.
Electrical
Connections Check wire connections. Make sure connections are tight.
Smoke and CO Verify devices are installed and working properly. Change batteries if
Detector necessary.
Circuit Breakers Check to see that the circuit breaker is clearly labeled. Exercise circuit

Replace any gaskets that show signs of damage.
Spark Electrode Clean. Set gap at 1/4" Clean probe with plumbers cloth to remove
oxides.
Combination Ignitor Check ionization in uA (i04 in the Inquiry Mode menu). Record high
and Flame Probe fire and low fire. Clean probe with plumbers cloth to remove oxides.
Condensate
Neutralizer Check condensate neutralizer. Replace if necessary.
Condensate Pipe Disconnect condensate pipe. Clean out dirt. Fill with water to level
of outlet and reinstall. (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 10" WC for Natural Gas, 8" to
14" WC for Propane).
Pressure Drop Measure drop in pressure on light off (no more than 1" WC).
Check Gas Pipe for
Check piping for leaks. Verify that all are properly supported.

Inspection Activities
The water heater must be full of water and the system fully
purged BEFORE powering the water heater. Performing any
work in the plumbing system without either powering off
the water heater or isolating the water heater through the
use of shut-off valves could result in a condition referred to
as "dry-firing". Dry-firing the water heater will damage the
heat exchanger, and could result in property damage, serious
personal injury, or death. Such damages ARE NOT covered by
water heater warranty.
