OPERATING YOUR WATER HEATER
Before Using
1.  Make sure the water heater has been properly    installed. See “Installing Your Water Heater”  section.
2.  Make sure the air filter is correctly seated, as it may shift  during shipping or installation. 
NOTICE: Make certain that there are no obstructions on 
top of the unit that may block inlet or exaust air flow. See 
“Repair Parts Illustration” section.
3.  Completely fill the tank with water (See “Water Piping”  section).

Adjusting the User Interface Module/Operational Modes
Water Temperature Adjustment
The water temperature can be adjusted from 95°F / 35°C to 
140°F / 60°C. Use the Up and Down Buttons  
 
on the front panel to set the desired temperature. The 
setting temperature will blink on the display, press Mode/
Enter button to confi  rm.

Operational Conditions
Water Odor
In each water heater there is installed at least one anode 
rod (see parts sections) for corrosion protection of the tank. 
Certain water conditions will cause a reaction with this rod 
and the water
. The most common complaint associated 
with the anode rod is one of a rotton egg smell in the 
hot water. This odor is derived from hydrogen sulfide gas 
disolved in the water. The smell is the result of four factors 
which must all be present for the odor to develop:
A....

14ANODE ROD INSPECTION
Each water heater contains at least one anode rod, which 
will slowly deplete (due to electrolysis) prolonging the life 
of the water heater by protecting the glass lined tank from 
corrosion. Adverse water quality, hotter water tempera-
tures, high hot water usage, hydronic heating devices and 
water softening methods can increase the rate of anode 
rod depletion. Once the anode rod is depleted, the tank 
will start to corrode, eventually developing a leak.
Certain water...

MAINTENANCE OF YOUR WATER HEATER
Temperature and Pressure
Relief Valve
Manually operate the temperature and pressure relief valve  
once a year to make sure it is working properly (Figure 14). 
To prevent water 
damage, the valve 
must be properly 
connected to a 
discharge line which 
terminates at an 
adequate drain.
Standing clear of the 
outlet (discharged 
water may be 
hot), slowly lift and 
release the lever 
handle on the 
temperature and 
pressure relief valve to allow the valve to operate...

Draining and Flushing
It is recommended that the tank be drained and 
fl ushed 
every 6 months to remove sediment which may build up 
during operation. The water heater should be drained if 
being shut down during freezing temperatures. To drain the 
tank, perform the following steps: 
1.  Turn off the power to the water heater at the circuit  breaker/fuse box.
2.  Open a nearby hot water faucet until the water is no  longer hot.
