Installation / Operation Instruction Manual

29
Maintenance continued-
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 annually
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.
WARNING
This water may be HOT.
