Maintenance continued-
5. Annually remove the inner door and main burner assembly to clean orifices
and related parts of any dirt or other foreign material. Inspect the burner
ports for obstructions or debris and clean with a wire brush as needed. Wire
brush and/or vacuum clean the combustion chamber as needed to remove
scale deposits and debris. NOTE: It is imperative for proper operation of
the water heater that the inner door be replaced in the original location.
6. At least once a year, check the combination temperature and pressure
relief valve to ensure that the valve has not become encrusted with lime.
Lift the lever at the top of the valve several times until the valve seats
properly without leaking and operates freely.
7. Monthly drain off a gallon of water to remove silt and sediment.
8. If the combination temperature and pressure relief valve on the appliance
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.
9. A combination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected periodically
(every 2 years) and replaced when necessary to prolong tank life. Water
conditions in your area will influence the time interval for inspection and
replacement of the anode rod. Contact the plumbing professional who
installed the water heater, or the manufacturer listed on the rating plate for
anode replacement information. The use of a water softener may increase
the speed of anode consumption. More frequent inspection of the anode is
needed when using softened (or phosphate treated) water.
10. The blower has sealed motor bearings and does NOT require adding oil.
11. Vent pipe and vent hood screen should be cleaned of any foreign material.
The screen is located inside the vent hood outlet and is accessible from the
outside of the hood. Do not reach inside the vent hood when the water
heater is in operation.
