WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH.
Follow these warnings exactly:
1. Disconnect power supply before wiring to pre-
vent electrical shock or equipment damage.
2. To avoid dangerous accumulation of fuel gas,
turn off gas supply at the appliance service val-
ve before starting installation, and perform
Gas Leak Test after completion of installation.
3. Always install sediment trap in gas supply line
to prevent contamination of gas control.
4. Do not force the gas control knob. Use only
your hand to turn the gas control knob. Never
use any tools. If the gas control knob will not
operate by hand, the gas control should be
replaced by a qualified service technician.
Force or attempted repair may result in fire or
explosion.
CAUTION
CAUTION
Never apply a jumper across or short the valve
coil terminals. This may burn out the heat antici-
pator in the thermostat or damage the electronic
direct ignition (DI) module.
IMPORTANT: These gas controls are shipped with pro-
tective seals over inlet and outlet tappings. Do not
remove seals until ready to connect piping.
Follow the appliance manufacturer instructions if avail-
able; otherwise, use the instructions provided on the fol-
lowing pages.
CONVERTING BETWEEN NATURAL AND LP
GAS
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH.
1. Do not use a gas control set for natural gas on
an LP gas system or a gas control set for LP gas
on a natural gas system.
2. When making conversion, main pilot burner
orifices must be changed to meet appliance
manufacturer specifications.
Refere to appliance manufacturer instructions for orifice
specifications and changeover procedure. Gas controls are
factory-set for natural (and manufactured) or LP gas. Do
not attempt to use a control set for natural (manufactured)
gas on LP gas, or a control set for LP on natural (manufac-
tured) gas.
Gas controls with standard or slow opening regulators
can be converted from one gas to the other with a conver-
sion kit (ordered separately). Order part no. 393691 to
convert from natural (manufactured) to LP gas; order part
no. 394588 to convert from LP to natural (manufactured)
gas. Controls with step opening regulators cannot be con-
verted.
INSTALL ADAPTERS TO CONTROL
If adapters are to be installed on the gas control, mount
them as follows:
Flanges:
1. Choose the appropriate flange for your application.
2. Remove seal over control inlet or outlet.
3. Assure O-ring is fitted in the groove of flange. If the
O-ring is not attached or is missing, do not use flange.
4. With O-ring facing control, align the screw holes on
the control with the holes in the flange. Insert and tighten
the screws provided with the flange. See Fig. 1. Tighten the
screws to 25 inch pounds of torque to provide a gas-tight
seal.
Fig. 1—Fasten flange to valve firmly, but do
not overtighten screws.
!
Bushings:
1. Remove seal over control inlet or outlet.
2. Apply moderate amount of good quality pipe com-
pound to bushing, leaving two end threads bare. On LP
installation, use compound resistant to LP gas. Do not use
Teflon tape.
3. Insert bushing in control and carefully thread pipe
into bushing until tight.
Complete instructions below for piping, installing con-
trol, and wiring. Make certain the leak test you perform on
the control after completing the installation includes leak
testing the adapters and screws. If you use a wrench on the
valve after flanges are installed, use the wrench only on the
flange, not the control. Refer to Fig. 5.
