Turn off the electrical power supply and close the manual gas shutoff valve
and the manual water control valve before servicing.
ͻ
Failure to do so could result in severe personal injury, or death.
WARNING
ͻ
Clean the cold-water inlet filter. (Refer to the Unit Draining and Filter Cleaning Section in this page.)
ͻ
Be sure that all openings for combustion and ventilation air are not blocked.
ͻ
The venting system should be checked annually for any leaks, corrosion, blockages or damage.
ͻ
The burner should be checked annually for dust, lint, grease or dirt.

flammable vapors and liquids.
ͻ
If the relief valve discharges periodically, it 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.
ͻ
Visually check the burner flames (see below) through the burner window in the burner assembly
located at the middle of the water heater.

The manufacturer recommends having the unit checked once a year or as necessary by a licensed
technician. If repairs are needed, any repairs should be done by a licensed technician.

This water heater comes equipped with heating blocks to protect it from damage associated with
freezing. When the freeze protection thermostat senses air temperature below 36.5
°F
(2.5
°C
), the
blocks will heat up to prevent freezing of the unit.
ͻ
To operate these freeze protection systems, there has to be electrical power to the unit. Damage
to the heat exchanger caused by freezing temperatures due to power loss is not covered under the
warranty. In cases where power losses can occur, consider the use of a backup power supply.
ͻ
In any areas subject to freezing temperatures, the manufacturer highly recommends an indoor installa-
tion with an indoor model.
ͻ
The manufacturer also highly recommends the use of a backflow preventer (sold separately) to mini-
mize the amount of cold air entering through the exhaust venting when the water heater is off.
ͻ
It is the installer’s responsibility to be aware of freezing issues and take all preventative measures. The
manufacturer will not be responsible for any damage to the heat exchanger as a result of freezing.
ͻ
If you will not be using your heater for a long period of time:
1. Completely drain the water out of the unit. Refer to p. 51.
2. Disconnect power to your heater.
This will keep your unit from freezing and being damaged.
Only pipes within the water heater are protected by the freeze protection system.
Any water pipes (hot or cold) located outside the unit will not be protected.
Properly protect and insulate these pipes from freezing.
