CAUTION
Before manually operating the valve, make sure that a drain line has been attached to the valve to direct
the discharge to an open drain. Failure to take this precaution could mean contact with extremely hot water
passing out the valve during this checking operation.
If the combination temperature and pressure relief valve on the water heater discharges periodically, this may be due to
thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to
correct this situation. Do not plug the combination temperature and pressure relief valve outlet.
WARNING
Above all, do not plug the temperature and pressure relief valve. This is not a solution and can create a
hazardous situation.
VENT AND AIR INTAKE SYSTEM
Examine the vent and air intake system at least annually. Points of inspection are as follows:
1. Check for obstructions and/or deterioration of vent piping and vent terminal. Replace immediately where
needed.
2. Vent pipe and vent terminal screen should be cleaned of any foreign material. The screen is located inside the
vent terminal outlet and is accessible from the outside of the vent terminal elbow. Do not reach inside the vent
terminal when the water heater is in operation.
3. Check all venting system connections for leakage and reseal as required.
COMBUSTION SYSTEM INSPECTION
Inspect the operation of the combustion system annually. Use the following procedure to inspect the combustion
system.
1. Adjust the thermostat to the Min. setting.
2. Turn off the main power switch of the water heater.
3. Remove the top of the combustion surround by unlatching it.
4. While observing the water heater display, turn on the main power switch.
5. Adjust thermostat to the Max. setting.
6. Watch the water heater display status indicator as the control goes through the sequence of operation as
previously described.
7. Upon ignition, observe the main burner flame.
8. Readjust thermostat to previous setting.
9. Replace combustion surround top and latch it securely in place.
WARNING
Do not run out of propane gas. Damage to the water heater may occur.
