ELECTRONIC IGNITION CONTROL
Each heater is equipped with a Honeywell ignition module. The
solid state ignition control, fig. 4, ignites the pilot burner gas by
creating a spark at the pilot assembly. Pilot gas is ignited and
burns during each running cycle. The main burner and pilot gases
are cut off during the OFF cycle. Pilot gas ignition is proven by the
pilot sensor. Main burner ignition will not occur if the pilot sensor
does not first sense pilot ignition.

AUTOMATIC FLUE DAMPER DEVICE
All units are equipped with an automatic flue damper that reduces
heat loss during the OFF cycles. The automatic flue damper
drive assembly is a field replaceable part and may be obtained
by contacting State Water Heaters.
Each automatic flue damper drive assembly is equipped with a
“Service Switch”, as shown in figure 5.
FIGURE 5
The “Service Switch” has 2 positions: AUTOMATIC OPERATION
and HOLD OPEN DAMPER. For normal operation the switch
should be in the AUTOMATIC OPERATION position.
If there is a problem with the damper the “Service Switch” can be
placed in the HOLD OPEN DAMPER position. When the switch
is placed in the HOLD OPEN DAMPER position the damper disc
will rotate to the open position and the heater may be used until
vent assembly is repaired or replaced. DO NOT turn the damper
disc manually; damage will occur to the drive assembly if operated
manually. Refer to TESTING DAMPER OPERATION section of
this manual for additional information.
CIRCULATING PUMP
A circulating pump is used when a system requires a
circulating loop or there is a storage tank used in conjunction
with the heater. Refer to the piping diagrams in this manual
for electrical hookup information and install in accordance
with the current edition of the National Electrical Code ANSI/
NFPA No. 70.
Only all bronze circulators should be used with commercial
water heaters.
Although circulators are oiled and operated by the manufacturer
some circulators must be oiled again before operating. Please
refer to manufacturer’s instructions.
DISHWASHING MACHINE REQUIREMENT
These appliances meet the NSF Standard 5 for sanitary
installations when used with the following leg kits, Part No’s.
6570-0 and 6570-7.
All dishwashing machines meeting the National Sanitation
Foundation requirements are designed to operate with water
flow pressures between 15 and 25 psi (103 Kpa and 173
Kpa). Flow pressures above 25 psi (173 Kpa), or below
15 psi (103 Kpa), will result in improperly sanitized dishes.
Where pressures are high, a water pressure reducing or flow
regulating control valve should be used in 180°F (82°C) line to
the dishwashing machine, and should be adjusted to deliver
water between these limits.
The National Sanitation Foundation also recommends circulation
of 180°F (82°C) water. Where this is done, the circulation
should be very gentle so that it does not cause any unnecessary
turbulence inside the water heater. The circulation should be
just enough to provide 180°F (82°C) water at the point of take-off
to the dishwashing machine. Adjust flow by means of the plug
cock in the circulating line.
INSTALLATION INSTRUCTIONS
REQUIRED ABILITY
INSTALLATION OR SERVICE OF THIS WATER HEATER
REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED
TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR
SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK
ARE REQUIRED.
WARNING
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT
IN SERIOUS PERSONAL INJURY OR DEATH.
UNCRATING
The heater is shipped with the flue damper already installed . The
wiring conduit runs from the thermostat to the damper drive cover.
Before turning unit on, check to make sure the wiring conduit is
securely plugged into damper drive.
LOCATING THE HEATER
When installing the heater, consideration must be given to
proper location. Location selected should be as close to the
stack or chimney as practicable, with adequate air supply and as
centralized with the piping system as possible.
