ANODE ROD REPLACEMENT
To replace the anode:
Turn off gas supply to the water heater.
Shut off the water supply and open a nearby hot-water
faucet to depressurize the water tank.
Drain approximately 5 gallons (20 litres) of water from
tank (Refer to “DRAINING THE TANK” for proper
procedures.) Close drain valve.
Remove old anode rod.
Use Te
fl
on® tape or approved pipe sealant on threads
and install new anode rod.
Turn on water supply and open nearby hot-water
faucet to purge air from water system.
Restart the water heater as directed under “Operating
Your Water Heater”. See the “Parts Reference
Illustration” for anode rod location.
TEMPERATURE-PRESSURE RELIEF VALVE
OPERATION
FIGURE 36
The temperature-pressure relief valve lever must be
operated at least once a year to ensure that the water
ways are clear. When checking the temperature-pressure
relief valve operation, make sure that:
No one is in front of or around the outlet of the
temperature-pressure relief valve discharge line.
The water discharge will not cause any property
damage, as the water may be extremely hot.
A discharge line is connected to this valve, directing
the flow of hot water from the valve to a proper
placement for disposal.
If water does not
fl
ow freely when the lever is in the open
position, replacement of the valve is required. Turn off the
cold water inlet heater and call a quali
fi
ed service man.
If after manually operating the valve (see Figure 36), it
fails to completely reset and continues to release water,
immediately close the cold water inlet to the water
heater, follow the draining instructions, and replace the
temperature-pressure relief valve with a new one.

If the temperature-pressure relief valve on the appliance
weeps or discharges periodically, this may be due to
thermal expansion. You may have a check valve installed in
the water line or a water meter with a check valve. Consult
your local water supplier or a quali
fi
ed service agency for
further information. Do not plug the temperature-pressure
relief valve.
MOTORS
Motors are permanently lubricated and do not need
periodic lubrication. Keep fan and motor free of dust and
dirt by cleaning annually.
SNOW ACCUMULATION
Keep the area around
fl
ue terminal free of snow and ice.
The appliance will not function properly if the intake air
or exhaust is impeded (blocked or partially blocked) by
obstructions.
CLEANING THE INLET WATER FILTER
The cold water inlet
fi
lter must be cleaned on a regular
basis. The frequency of this cleaning is dependent on the
quality of your local water supply. You will need to prepare
a bucket to collect some of the draining water. The cold
water inlet
fi
lter is located inside the door on the left-hand
side of the heat engine. To access the inlet
fi
lter:
