CAUTION: The burner chamber is a sealed area. If

the burner access door is removed, the burner

access door gasket must be replaced. This should

only be done by a qualified service technician.

Inspect the area of the installed water heater for the

presence of materials that could produce flammable

vapors (Ex: gasoline, cleaning compounds, paints/

solvents) or the presence of bleach or ammonia.

Remove any of these materials and thoroughly ven-

tilate the area where the water heater is located. If

the area is not clear of flammable vapors, the

Flammable Vapor sensor (FV Sensor) will trip

immediately.

Parts Included in this Kit: Inspect contents of this kit for

possible missing or damaged components. See Figure 1.

ADDITIONAL INSTRUCTIONS:

Refer to the Use and Care Manual supplied with the water

heater for complete information on the installation, lighting

instructions, operation and maintenance of the water heater.

DETERMINE THE TYPE OF COMBINATION

CONTROL GAS VALVE (THERMOSTAT)

Before you can proceed with these instructions you need to

determine which type of Control Gas Valve is on the water

heater. If the water heater was built before October 2007 it may

have an Invensys/Robertshaw Control Gas Valve. If the water

heater was built after October 2007 it will have the White

Rodgers Control Gas Valve. See Figure 2 and 3 to determine

which Control Gas Valve you have and follow the instructions

for that type of Control Gas Valve.

INVENSYS/ROBERTSHAW CONTROL GAS VALVE

INSTRUCTIONS ONLY:

1. TO TURN OFF ELECTRIC POWER AND GAS SUPPLY

TO THE WATER HEATER:

Unplug the power cord to the water heater and turn off the

blower switch on top of the water heater. Shut off the gas sup-

ply at the main gas supply line. Set the Control Gas Valve dial

to the lowest setting “Vacation” by rotating the dial counter

clockwise until it stops. Depress the manual lever on the top

of the Control Gas Valve until it snaps clockwise to the “Off”

position. Do not force the manual lever. See figure 4.

REMOVAL OF THE FV SENSOR:

Remove the outer door cover from the jacket. Detach the flam-

mable vapor sensor from the bottom of the jacket located under

the opening for the outer door cover. Disconnect the two FV

sensor wire terminals from the male tabs on the FV Sensor.

Leave the FV Sensor wire harness in place it will be re-used

for the new FV Sensor. See Figure 5.

3. (INVENSYS/ROBERTSHAW CONTROL GAS VALVE)

FLAMMABLE VAPOR SENSOR INSTALLATION:

Insert the FV Sensor into the FV Sensor cap plug. See Figure

6. Connect the FV Sensor wires to the FV Sensor through the

sensor hole from the back side to the front side of the jacket.

Connect the two sensor wire terminals to the male tabs on the

sensor. Note: Either terminal may connect to either tab. Install

6. (Invensys/Robertshaw Control Gas Valve) Temperature Setting: Danger: Hotter water increases the potential for Hot Water SCALDS. Set the thermostat dial to the recommended temperature setting of 120 deg. F (49 deg.C) or less by rotating the thermostat dial clockwise. Note: The large white triangle left of the text “Vacation” on the dial is the 120 – deg. F setting. Check to see if the main burner has flames by looking through the sight glass.
