CABINET ASSEMBLY
CABINET PANELS
There are five panels that comprise the cabinet assembly. The
ends of the cabinet allow access to all controls and plumbing.
Please confirm all joints are attached correctly and sealed to
prevent water leakage inside the cabinet, see Figure 26.

ADDITIONAL CONTROLS
GAS VALVE
The gas valve is used to supply the gas to the unit during heat up
periods. The ignition control board monitors the thermostat's call
for heat and sends a signal to the gas valve when to open to allow
gas flow, see Figure 27.
FIGURE 27
FLAME SENSOR
The flame sensor is used to sense the burner flame. When there
is sufficient flame, and the burner is properly grounded, the flame
sensor signals back to the ignition board that the burner is operating
properly and to maintain the operation of the gas valve until the
thermostat is satisfied.

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.
INSULATION BLANKETS
Insulation blankets available to the general public for external use
on gas water heaters are not approved for use on your State
water heater. The purpose of an insulation blanket is to reduce the
standby heat loss encountered with storage tank water heaters.
Your State water heater meets or exceeds the ASHRAE/IES 90.1b
1999 standards with respect to insulation and standby loss
requirements, making an insulation blanket unnecessary.
LOCATING THE HEATER
WARNING
THERE IS A RISK IN USING FUEL BURNING APPLIANCES SUCH
AS GAS WATER HEATERS IN ROOMS, GARAGES OR OTHER
AREAS WHERE GASOLINE, OTHER FLAMMABLE LIQUIDS OR
ENGINE DRIVEN EQUIPMENT OR VEHICLES ARE STORED,
OPERATED OR REPAIRED. FLAMMABLE VAPORS ARE HEAVY AND
TRAVEL ALONG THE FLOOR AND MAY BE IGNITED BY THE
HEATER’S IGNITER OR MAIN BURNER FLAMES CAUSING FIRE
OR EXPLOSION. SOME LOCAL CODES PERMIT OPERATION OF
GAS APPLIANCES IF INSTALLED 18 INCHES (46 cm) OR MORE
ABOVE THE FLOOR. THIS MAY REDUCE THE RISK IF LOCATION
IN SUCH AN AREA CANNOT BE AVOIDED.
THE HEATER SHALL BE LOCATED OR PROTECTED SO IT IS
NOT SUBJECT TO PHYSICAL DAMAGE BY A MOVING VEHICLE.
DO NOT LOCATE THE HEATER WHERE NOISE FROM THE
EXHAUST OR INTAKE WILL BE OBJECTIONABLE. THIS
INCLUDES LOCATIONS CLOSE TO OR ACROSS FROM WINDOWS
AND DOORS.
