CAUTION
Never apply a jumper across or short the valve coil
terminals. This can burn out the heat anticipator in
the thermostat or damage the electronic intermit-
tent pilot (IP) 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 following instructions.

GAS
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH
Do not attempt to use a gas control set for natural
gas on LP gas or a gas control set for LP gas on
natural gas.
Convert standard-opening gas controls from natural gas
to LP gas with the conversion kit included with this
®
TRADELINE gas control. Part number 393691 will con-
vert from natural to LP gas. Part number 394588 will convert
from LP to natural gas.
USE PIPE ADAPTER TO SOLVE SWING RADIUS
PROBLEMS
In some field service applications, space limitations make
it difficult or impossible to thread the gas control onto the gas
supply pipe. This problem can be resolved for many installa-
tions by using a pipe adapter. Install the pipe adapter on the
end of the supply pipe in place of the gas control by following
the same precautions and instructions that are used for
installing the gas control. After the pipe adapter is installed,
attach the gas control to the adapter as outlined in the Install
Pipe Adapters to Gas Control section.
NOTE: Using a pipe adapter increases the overall length of
the gas control.
INSTALL PIPE ADAPTER TO GAS CONTROL
Install adapter to gas control as follows:
Bushings
1. Remove seal over gas control inlet or outlet.
2. Apply moderate amount of good quality pipe com-
pound to bushing, leaving two end threads bare. See Fig. 1.
3. Insert bushing in gas control and carefully thread pipe
into the bushing until tight.
Fig. 1—Use moderate amount of pipe compound.

LOCATION
Locate the combination gas control in the appliance
vestibule on the gas manifold. In replacement applications,
locate the gas control in the same location as the old control.
Do not locate the gas control where it can be affected by
steam cleaning, high humidity, dripping water, corrosive
chemicals, dust or grease accumulation, or excessive heat.
For proper operation, follow these guidelines:
• Locate gas control in a well-ventilated area.
• Mount gas control high enough above the cabinet bot-
tom to avoid exposure to flooding or splashing water.
• Make sure the ambient temperature does not exceed
the ambient temperature ratings for each component.
• Cover gas control when the appliance is cleaned with
water, steam, or chemicals or to avoid dust and grease
accumulation.
• Avoid locating gas control where exposure to corro-
sive chemical fumes or dripping water is possible.
INSTALL PIPING TO GAS CONTROL
All piping must comply with applicable codes and ordi-
nances 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, make sure the ends are square, deburred and
clean. Make sure all tubing bends are smooth and without
deformation.
2. Run pipe or tubing to the gas control. If tubing is used,
obtain a tube-to-pipe coupling to connect the tubing to the
gas control.
3. Install sediment trap in the supply line to the gas
control. See Fig. 2.
INSTALL GAS CONTROL
1. This gas control can be mounted from 0 to 90 degrees
in any direction from the vertical position of the gas control
knob.
2. Mount the gas control so gas flow is in the direction of
the arrow on the bottom of the gas control.
3. Thread pipe the amount shown in Table 4 for insertion
into the gas control.
IMPORTANT: Do not thread pipe too far. Valve distortion
or malfunction can result when the pipe is inserted
too deeply into the gas control.

APPLY A MODERATE AMOUNT OF
PIPE COMPOUND TO PIPE ONLY
(LEAVE TWO END THREADS BARE).
