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.
. This control must be installed or serviced only by a
. Apply pipe compound to the male threads of the pipe that goes
into the control, leaving the ﬁrst two or three threads clean.
. 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.
. 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.
. 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 ONYOUR
. 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.
. Make the main burner connection. Do not use pipe joint
compound or Teﬂon tape.
. 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
. DO NOT use joint compound or tape on the union
. Make the electrical connections to the control. There
are two plastic connectors that plug into the bottom of
the control. The connectors are “keyed” so that they can
only be inserted one way. Make sure that the connectors
are properly aligned before attempting to insert. DO
NOT FORCE THE CONNECTORS; DAMAGE TO THE
CONTROL WILL RESULT.
REMOVING THE OLD CONTROL
. Shut off the gas to the water heater
. Turn off electrical power to the water heater.
. Remove the two plastic wire connectors that plug
into the bottom of the control. The connectors have
latches which must be depressed. DO NOT FORCE
THE CONNECTORS, DAMAGE TO THE WIRING MAY
. To ﬁll the water heater with water:
a. Close the water heater drain valve by turning the
handle to the right (clockwise). The drain valve is on
the lower front of the water heater.
. Shut off the water at the cold water inlet.
. Connect a hose to the water heater drain cock. Drain the
water to a nearby drain. Open a hot water faucet for faster
b. Open the cold water supply valve to the water heater.
. Disconnect the gas line at the union (Figure 1). Remove
the piping from the old control.
The cold water supply valve must be left open when the
water heater is in use.
. Remove the control by turning it counterclockwise (
INSTALLING THE NEW CONTROL
c. To ensure complete ﬁlling of the tank, let air exit by
opening the nearest hot water faucet. Allow water to
run until a constant ﬂow is obtained. This will let air out
of the water heater and the piping.
All piping must comply with local and state ordinances or
with the National Fuel Gas Code (ANSI Z223.1-NFPA 54),
Dirt or contamination in the gas line can block the control
from operating creating a risk of explosion, injury, or death.
d. Check all new water piping for leaks. Repair as needed.
