Operating the water heater

29

Safety Precautions

   Do turn off manual gas shut-off valve if water heater 

has been subjected to over heating, fire, flood, physi-

cal damage or if the gas supply fails  

to shut off.

   Do Not turn on water heater unless it is completely 

filled with water.

   Do Not turn on water heater if cold water supply 

shut-off valve is closed.

   Do Not allow combustible materials such as newspa-

per, rags or mops to accumulate near  

water heater.

   Do Not store or use gasoline or other flammable 

vapors and liquids, such as adhesives or paint thinner, 

in vicinity of this or any other appliance.  

If such flammables must be used, open doors  

and windows for ventilation, and all gas burning 

appliances in the vicinity should be shut off including 

their pilot burners, to avoid vapors lighting.

NOTICE: Flammable vapors can be drawn by air 

currents from surrounding areas to the water heater.

   If there is any difficulty in understanding or following 

the Operating Instructions or the Care and Cleaning 

section, it is recommended that a qualified person or 

serviceman perform the work.

CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a 

long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such 

gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink 

before using any electrical appliance connected to the hot water system. If hydrogen is present, there will be an unusual sound 

such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame near the faucet at the 

time it is open.

!

DANGER: 

Hotter water 

increases the Potential  

for Hot Water SCALDS

Households with small 

children, disabled, or elderly 

persons may require a 120°F  

(49°C ) or lower gas control 

(thermostat) setting to 

prevent contact with unsafe 

water temperatures.

Water Temperature Setting

The temperature of the water in the water 

heater can be regulated by pressing the 

buttons on the front of the gas control 

(thermostat).
Safety and energy conservation are factors 

to be considered when selecting the water 

temperature setting of the water heater’s 

gas control (thermostat(s)). The lower the 

temperature setting, the greater the savings 

in energy and operating costs.
To comply with safety regulations, the gas 

control (thermostat) was set at its lowest 

setting before the water heater was shipped 

from the factory.  The recommended 

starting point temperature is 120°F (49

°C)

.

Water temperatures above 125°F (52

°C)

can cause severe burns or death from 

scalding. Be sure to read and follow the 

warnings outlined in this manual and on 

the label located on the water heater near 

the gas control thermostat.
Mixing valves are available for reducing 

point of use water temperature by mixing 

hot and cold water in branch water lines. 

Contact a licensed plumber or the local 

plumbing authority for further informa-

tion.
The chart on the next page may be used 

as a guide in determining the appropriate 

water temperature for your home.

Operating Procedure

This water heater is equipped with a hot 

surface ignitor to light the main burner. 

There is no pilot light to be lit, but on initial 

start-up, it is recommended that the outer 

door be removed (leave inner door in place 

for safety) to view through the sight glass if 

the hot surface ignitor and main burner are 

operating properly.
Once filled with water, it is only necessary 

to plug the power cord in and make sure the 

“ON/OFF” switch located on the blower 

assembly is in the “ON” position to put the 

water heater into operation. Within seconds 

the hot surface ignitor should heat up, then 

the gas valve should open and the main 

burner ignite. After the main burner ignites, 

replace the outer door. If no main burner 

flame is established, the gas control will go 

through three trials for ignition before going 

into a lock-out. A warning light will alert the 

user of this lock-out condition. If this hap-

pens, refer to “Troubleshooting Guide.”
TO SHUT OFF WATER HEATER – Turn 

switch on the blower assembly to the “OFF” 

position.
