Preventative Maintenance
It is suggested for peak performance that the water heater be serviced annually.
1. Check for discharge from the T & PR valve. When the burner is off there should be no
discharge of water. When the burner is operating, a small discharge of water may be
evident. Operate the valve easing lever to ensure the valve opens and resets properly.
Always open and close the valve gently. The T&PR valve should be replaced at 5
yearly intervals.
2. Check that the pilot is burning with a small blue flame. Remove and clean the pilot
burner if there is a tendency for yellowing of the flame. Ensure the pilot ignites the main
burner with no delayed ignition.
Note: Water heaters operating on LP gases may exhibit a slightly yellow pilot flame;
this is a normal condition.
3. Check the main burner pressure and compare to that indicated on the rating label, a
reading within 10% is acceptable. Remember to replace the pressure test point screw.
4. Check main burner flame to ensure all parts ignite readily and that the flame is blue
with little or no yellowing of the tips. If necessary, adjust primary air shutter to eliminate
yellowing without introducing a harsh noisy blue flame.
5. Check operation of the piezo igniter. The pilot should light after two (2) or three (3)
operations of the piezo, if not, check for correct spark gap, burnt electrode or a cracked
ceramic insulator.
6. Check operation of the flame failure magnetic valve. The magnetic valve should be
held open within one (1) minute by the electric current generated by the thermocouple.
If not check the output of the thermocouple.
7. Check for signs of excessive corrosion on the jacket and inside the combustion
chamber.
8. Indoor Models Only – Clean the pilot viewing mirror.
9. Warn customer of the danger of using flammable materials or aerosol spray packs near
the water heater. Aerosols and harsh chemicals can cause premature failure of water
heater components.

“Rheem Plus Tempering Valve Annual Service” on page 37.
