The 25M series gas control is a compact, multifunctional

valve, with a direct-acting regulator ideal for use in pilot valve

applications, thru-the wall heaters, RV heaters, gas clothes

dryers, hearth products, radiant heat systems, water heaters,

cooking applications, agricultural heaters/ dryers, or other

high-efﬁciency equipment. The 25M valve, provided with a

straight inlet, has various outlet conﬁgurations

that, when coupled with the various pipe sizes available,

make for easy adaptation to a given application.

Optional features, such as the inlet pressure tap, increase the

ﬂexibility in adapting this valve.

Available conﬁgurations include:

• Appliance (Series valve is a combination gas pressure

regulator and dual

automatic gas valve. These valves are designed for use on

gas clothes dryers.)

• Manifold (The manifold type 25M series valve is a

combination gas pressure regulator and redundant

automatic gas valve. Two-Stage version (for applications

requiring both high-ﬁre and low-ﬁre settings)

• Quiet-Type (series manifold gas valve is typically a

combination of gas pressure regulator and dual automatic

gas valve suitable for applications requiring EN approval.)

INSTALLATION

1. Before attempting to service device, unplug power

cord, turn off main gas supply and consult device

manufacturer's instructions for accessing gas valve.

2. Disconnect gas line form the device.

3. Remove the access panel if is need it as the

manufacturer’s instructions indicate it.

4. The gas valve/burner assembly should now be visible.

5. Disconnect the wiring harness from gas valve. If the gas valve is not using ﬁtting and oriﬁce

screw go to step 15. (see ﬁgure 1)

6. Remove screw(s) fastening the mounting bracket.

7. Remove the gas inlet pipe as Manufacturer’s instructions

indicate it.

8. The gas valve should now be free to slide out of burner

and off of mounting bracket. Take care not to disturb the

air shutter.

CAUTION

WARNING

!If you do not follow these instructions exactly, a fire or explosion may

result, causing property damage, personal injury or loss of life.

DO NOT BEGIN INSTALLATION UNTIL YOU READ THE

FOLLOWING PRECAUTIONS.

1. Failure to turn off electric or main gas supply to

clothes dryer could cause personal injury and/or

property damage by shock, gas suffocation, ﬁre,

and/or explosion.

2. Do not use this control on circuits exceeding

speciﬁed voltage. Higher voltage will damage the

control and may cause shock or ﬁre hazard.

3. NEVER USE FLAME OR ANY KIND OF SPARK TO

CHECK FOR GAS LEAKS–COULD CAUSE FIRE

AND/OR EXPLOSION.

4. Do not use a control set for natural gas with LP gas,

or a control set for LP gas with natural gas. Personal

injury and/or property damage, gas suffocation, ﬁre,

and/or explosion may result.

1. Do not short out terminals on gas valve or primary

control to test. Short or incorrect wiring can cause

equipment damage, property damage, and/or

personal injury.

2. This control is not intended for use in locations

where it may come in direct contact with water.

Suitable protection must be provided to shield the

control from exposure to water (dripping, spraying,

rain, etc.).

INSTALLATION

9. Remove inlet ﬁtting from old gas valve and set it aside.

Take care not to damage the sealing surfaces. This part

could be reused (if is need it).

10. Clean the threads of the inlet ﬁtting. Apply pipe sealant

(approved for all gases) to the threads. Install the ﬁtting into

the inlet of the new valve and tighten to 200 lbf-in (16.6 lbf-

ft) using a 3/8 inch hex head wrench (if it is needed).

11. Remove oriﬁce screw from old gas valve and set it aside.

Take care not to damage the sealing surfaces. This part

will be reused.

12. Inspect the threads of the oriﬁce screw and clean if

necessary.

13. Inspect the oriﬁce hole and remove any foreign material.

Install oriﬁce screw into new valve and tighten to 40 lbf-in.

Do not use any pipe sealant.

14. Slide the outlet boss of the new valve into the burner. Take

care not to disturb the air shutter.

15. Fasten the gas valve to the mounting bracket using the

screw(s) removed earlier.

16. Connect the gas inlet pipe to the inlet ﬁtting by threading

the union together and tightening to 150 lbf-in (12.5 lbf-ft).

17. Reconnect the wiring harness to the gas valve.

18. Apply pipe sealant to the threads of the inlet gas pipe and

reconnect the gas line to the device.

19. Turn on gas supply and Check for leaks.

20. Remove the outlet pressure tap from the gas valve (see

ﬁgure 2). Apply pipe sealant to the 1/8-inch NPT threads

of a hose barb. Install the hose barb into the outlet

pressure tap and tighten to 40 lbf-in (see ﬁgure 3).

21. Connect a manometer to the hose barb. Manometer

should be capable of measuring pressure from 2.5" WC

up to 14.0" WC.

22. Plug dryer power cord into electrical socket.

23. Energize device and verify ignition. Also observe the

reading on the manometer. It should read the same outlet

pressure as stated on the rating plate on the old gas

valve. If it does not, see section on Pressure Regulator

Adjustment.

24. De-energize the dryer.

25. Remove the hose barb.

26. Apply pipe sealant to the 1/8 inch NPT used hex pipe

plug. Install the 1/8 inch NPT hex pipe plug into the outlet

pressure tap and tighten 40 lbf-in. (Could ﬁnd BSP thread

depending of the model)

27. Check for leaks.

28. Reinstall the cover of the device if it is needed.

PRESSURE REGULATOR

ADJUSTMENT

This control was shipped from the factory with the regulator

set as speciﬁed on the control label. Consult the appliance

rating plate to ensure burner manifold pressure is as speciﬁed.

If outlet pressure adjustment is required, follow these steps.

NOTE

If a valve has been factory-adjusted for the 2.5 to 5 inches W.C.

range, it cannot be ﬁeld-adjusted outside that range. This is

also true for valves adjusted to the 7.0 to 12 inches W.C. range

for LP gas.

1. Unplug power cord to the appliance.

2. Slide device away from wall.

3. Close manual shut-off valve for device, if none present, shut off gas supply line where it enters the building.

A. This appliance does not have a pilot. It is equipped with an

ignition device which automatically lights the burner. Do not

try to light the burner by hand.

B. BEFORE OPERATING smell all around the appliance area

for gas. Be sure to smell next to the ﬂoor because some gas

is heavier than air and will settle on the ﬂoor.

FOR YOUR SAFETY

“WHAT TO DO IF YOU SMELL GAS”

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use any

phone in your building.

• Immediately call your gas supplier from a neigh-

bor’s phone. Follow the gas supplier’s instruc-

tions.

• If you cannot reach your gas supplier, call the

ﬁre department.

C. Do not use this appliance if any part has been under

water. Immediately call a qualiﬁed service technician

to inspect the appliance and to replace any part of

the control system and any gas control which has

been under water.

WARNING

!If you do not follow these instructions exactly, a fire or explosion

may result causing property damage, personal injury or loss of life.

LIGHTING INSTRUCTIONS

ADJUSTMENT

If your valve has a regulator blocked open (see

ﬁgure 1) it is a non-regulable valve.

1. Unplug dryer power cord.

2. Attach a hose and manometer to the hose barb in the tap

of the valve (see ﬁgure 4).

3. Turn on system power and energize valve.

4. Remove regulator cover screw and turn regulator

adjust screw clockwise ( ) to increase pressure,

or counterclockwise ( ) to decrease pressure

(see ﬁgure 5). Always adjust regulator to provide the

correct pressure according to the original equipment

manufacturer’s speciﬁcations listed on the appliance

rating plate.

5. Replace regulator cover screw and tighten securely.

6. Turn off all electrical power to the system.

7. Remove manometer hose from outlet pressure hose barb.

8. Remove hose barb and replace plug. Use pipe sealant.

9. Plug in power cord.

10. Using a leak detection solution, check for leaks at

pressure boss screw. Bubbles forming indicate a leak.

SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY.
