INSTALLATION
NOTE
1. This control must be installed or serviced only by a qualified
service person.
2. For your safety, this control is supplied with tamper
resistant screws. Do not attempt to repair or adjust the
control. If you experience problems, replace the control
immediately. Continuing to use a damaged control could
result in fire and/or explosion.
3. An odorant has been added to the gas to help you detect it.
Before lighting, search for the odor of gas by sniffing at
floor level around the water heater.
4. In some situations, the gas may lose its odor.To detect
unodorized gas, you must have a gas detector, which can be
purchased from your gas company. If you do not have a
detector and have the slightest suspicion that gas may be
present, get out of the house and call the gas company.
DO NOT RELY TOTALLY ON YOUR NOSE.
REMOVING THE OLD CONTROL
1. Locate the gas control. Before performing any maintenance,
turn the gas control thermostat knob to the OFF setting.
(Figure 3)
2. Close gas shut off valve.
3. Remove the two electrical connections that are plugged
into the control (Figure 2).
4. Shut off the water at the cold water inlet.
5. Connect a hose to the water heater drain cock. Drain the
water to a nearby drain. Open a hot water faucet for faster
draining.
6. Disconnect the gas line at the union (Figure 1). Remove the
piping from the old control.
7. Disconnect main burner tube fitting and pilot tube fittings
(Figure 2).
8. Remove the control by turning counter clockwise ( )if
needed, a short piece of 1/2" black iron pipe can be
screwed into the control inlet to increase leverage.
INSTALLING THE NEW CONTROL
All piping must comply with local and state ordinances or with the
National Fuel Gas Code (ANSI Z223.1-NFPA 54), whichever applies.
1. Apply pipe compound to the male threads that screw into
the tank, leaving the first two or three threads clean.
2. Install control in the tank. Turn clockwise ( ). Use a short
piece of pipe to help in turning. Align the control so that the
burner tube may be connected.
3. Reconnect the main burner and pilot tube connection. Do
not use pipe joint compound or Teflon tape.
4. Connect the gas line. Use new black iron pipe that has been
properly reamed. If old pipe is used, be sure it is clean and
free from rust and scale. Use pipe joint compound on male
threads only. (Use pipe joint compound approved for natural
and LP gas service.) Do not use Teflon tape.Do not apply
compound to the first two threads.
5. Reconnect gas line at the union. DO NOT use joint
compound or tape on the union connection.
6. Reconnect the electrical connections to the control. There
are three connections for the control. Connect the positive
lead from control to the thermal switch on the tank.
Connect negative lead (white) from pilot generator to the
negative terminal on control. Connect piezo spark connector
to igniter wire connector (Figure 2).
NOTE
The cold water supply valve MUST be left open when the
water heater is in use
WARNING
Dirt or contamination in the gas line can block the control from
operating creating a risk of explosion, injury, or death. To protect
the control from dirt and contamination, a drip leg or sediment
trap (see Figure 1) must be installed in the piping leading to the
control.
