Converting Between Natural and LP 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.
To convert a gas control from natural to LP gas or from
LP to natural gas, contact your Resideo representative.
Convert standard or slow opening gas controls from one
gas to another with a conversion kit (ordered separately).
Order part number 393691 to convert from natural to LP
gas. Order part number 394588 to convert from LP to
natural gas. Step-opening gas controls can not be
converted.
Install Adapters to Gas Control
Install adapters to gas control as follows:
Flanges
1. Choose the appropriate flange for your application.
2. Remove seal over gas control inlet or outlet.
3. Make sure the O-ring fits into the flange groove. If
the O-ring is not attached or is missing, do not use
the flange.
4. With the O-ring facing the gas control, align the
screw holes on the gas 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.
Bushings
1. Remove seal over gas control inlet or outlet.
2. Apply moderate amount of good quality pipe
compound to bushing, leaving two end threads
bare. See Fig. 3. On LP installation, use compound
resistant to LP gas. Do not use Teflon tape.
3. Insert bushing in gas control and carefully thread
pipe into the bushing until tight.
Using Adapters to Solve Swing Radius
Problems
In some field service applications, it is difficult or
impossible to thread the gas control onto the gas supply
pipe because of space limitations. This problem can be
resolved for many installations by using an adapter.
Install the 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 adapter is installed, attach the gas control to
the adapter as outlined above.
NOTE: Using an adapter increases the overall length of
the gas control.

Fig. 1. Install flange to gas control.
Location
The combination gas control is mounted in the appliance
vestibule on the gas manifold. If this is a replacement
installation, mount 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.
To safeguard 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.
• 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
corrosive chemical fumes or dripping water is
possible.
Install Piping to Gas Control
All piping must comply with applicable codes and
ordinances or with the National Fuel Gas Code (ANSI
Z223.1 NFPA No. 54), whichever applies. Be sure tubing
installation complies 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.
Fig. 2. Install sediment trap.
3. Thread pipe the amount shown in Table 4 for
insertion into the gas control or flange. Do not
thread pipe too far. Valve distortion or malfunction
can result when the pipe is inserted too deeply into
the gas control.
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. Refer to Fig. 3.
5. Remove seals over gas control inlet and outlet if
necessary.
6. Connect pipe to gas control inlet and outlet. Use
wrench on the square ends of the gas control. If a
flange is used, place wrench on flange rather than
on gas control. Refer to Fig. 4 and 5.

make sure all controls operate properly.
MAINTENANCE
WARNING
Fire or Explosion Hazard
Can cause property damage, severe injury, or
death.
Improper cleaning or reassembly can cause gas
leakage. When cleaning, be sure that the control
is reassembled properly and perform gas leak
test.
Regular preventive maintenance is important in
applications such as commercial cooking, agricultural
and industrial operations that place a heavy load on
system controls because:
• In many such applications, particularly commercial
cooking, the equipment operates 100,000 to 200,000
cycles per year. Such heavy cycling can wear out the
gas control in one to two years.
• Exposure to water, dirt, chemicals and heat can
damage the gas control and shut down the control
system.
The maintenance program should include regular
checkout of the gas control; see Startup and Checkout
section. To check out the control system, see the
appliance manufacturer literature. Maintenance
frequency must be determined individually for each
application. Some considerations are:
•Cycling frequency. Appliances that may cycle 100,000
times annually should be checked monthly.
•Intermittent use. Appliances that are used seasonally
should be checked before shutdown and again before
the next use.
•Consequence of unexpected shutdown. Where the
cost of an unexpected shutdown would be high, the
system should be checked more often.
•Dusty, wet, or corrosive environment. Since these
environments can cause the gas control to deteriorate
more rapidly, the system should be checked more
often.
If the gas control will be exposed to high ammonia
conditions; i.e., those used in greenhouses or animal
barns, contact your Resideo sales representative to
request a gas control with corrosion resistant
construction.
The gas control should be replaced if:
• It does not perform properly on checkout or
troubleshooting.
• The gas control knob is hard to turn or push down, or
it fails to pop back up when released.
• The gas control is likely to have operated for more
than 200,000 cycles.
Service
WARNING
Fire or Explosion Hazard
Can cause property damage, severe injury, or
death.
Do not disassemble the gas control; it contains
no replaceable components. Attempted
disassembly or repair can damage the gas
