Installation Instructions for the Trained Service Technician.
Application
These direct ignition gas controls are used in gas-fired
appliances with up to 200 cfh capacity on natural gas. They
include safety shutoff, a manual valve, one or two automatic operators and a pilot adjustment. See Table 1 for
model differences and Table 2 for temperature ranges and
regulator types.
BODY PATTERN: Straight through with 1/2 in. inlet
and 1/2 in. outlet.
PIPE ADAPTERS: Angle and straight adapters available
for 3/8, 1/2 and 3/4 in. pipe. See Table 3.
TABLE 1—DIRECT IGNITION COMBINATION GAS CONTROL MODELS.
These gas controls are factory-set for natural (and manu-
factured) gas 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 (manufactured) gas.
Controls with standard or slow opening regulators can be
converted from one gas to the other with a conversion 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 converted.

Installation
WHEN INSTALLING THIS PRODUCT…
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out product operation as provided in these instructions.
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH.
Follow these warnings exactly:
1. Disconnect power supply before wiring to prevent electrical shock or equipment damage.
2. To avoid dangerous accumulation of fuel gas,
turn off gas supply at the appliance service valve 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 anticipator 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 available; otherwise, use the instructions provided on the following pages.

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 (manufactured) gas.
Gas controls with standard or slow opening regulators
can be converted from one gas to the other with a conversion 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 converted.
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.

DO NOT OVERTIGHTEN SCREWS. TIGHTEN TO

Bushings:
1. Remove seal over control inlet or outlet.
2. Apply moderate amount of good quality pipe compound 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 control, 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.

LOCATION
The combination gas control is mounted in the appliance vestibule on the gas manifold. If this is a replacement
application, mount the gas control in the same location as
the old control.
Locate the combination gas control where it cannot be
affected by steam cleaning, high humidity, or dripping
water, corrosive chemicals, dust or grease accumulation or
excessive heat. To assure proper operation, follow these
guidelines:
• Locate gas control in a well-ventilated area.
• Mount gas control high enough above the cabinet
bottom to avoid exposure to flooding or splashing
water.
• Assure the ambient temperature does not exceed the
ambient temperature ratings for each component.
• Cover gas control if appliance is cleaned with water,
steam, or chemicals or to avoid dust and grease
accumulation.
• Avoid locating gas control where exposure to corrosive chemical fumes or dripping water are likely.
Install Piping to Gas Control
All piping must comply with local codes and ordinances
or with the National Fuel Gas code (ANSI Z223.1 NFPA
No. 54), whichever applies. Tubing installation must comply with approved standards and practices.
1. Use new, properly reamed pipe free from chips. If
tubing is used, assure the ends are square, deburred and
clean. All tubing bends must be smooth and without deformation.
2. Run pipe or tubing to the control. If tubing is used,
obtain a tube-to-pipe coupling to connect the tubing to the
control.
3. Install sediment trap in the supply line to the gas
control. See Fig. 2.
Install Control
1. This control can be mounted 0-90 degrees, in any
direction, from the upright position of the gas control knob,
including vertically.
2. Mount the control so gas flow is in the direction of
the arrow on the bottom of the control.
3. Thread pipe into control. Do not thread pipe to far.
Valve distortion or malfunction may result if the pipe is
inserted too deeply, refer to Table 4.

4. Apply a moderate amount of good quality pipe compound (do not use Teflon tape) to pipe only, leaving two
end threads bare. On LP installations, use compound resistant to LP gas. See Fig. 3.
5. Remove seals over control inlet and outlet if necessary.
6. Connect pipe to control inlet and outlet. Use wrench
on the square ends of the control. If a flange is used, place
wrench on flange rather than control. Refer to Figs. 4 and 5.
