main valve that controls gas ow to the main burner,

a pressure regulator to maintain a constant outlet

pressure, integral gas pressure switch and a two

position on/o switch for electrical shuto.

Type of Gas: Natural gas

LP gas (use conversion kit)

CAUTION

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.).

WARNING

Before beginning any modication, be sure ALL electrical disconnects are in the OFF position.

TAG THE DISCONNECT SWITCHES WITH A SUITABLE WARNING LABEL. Electrical shock can

cause personal injury or death.

PRECAUTIONS

WARNING

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

explosion may result causing property damage, personal

injury or loss of life.

1. Failure to turn o electric or main gas supply to heating system could cause personal injury

and/or property damage by shock, gas suocation, re, and/or explosion.

2. Do not use this control on circuits exceeding specied voltage. Higher voltage will damage

the control and may cause shock or re 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 natu-

ral gas. Personal injury and/or property damage, gas suocation, re, and/or explosion

may result.

DO NOT BEGIN INSTALLATION UNTILYOU READTHE FOLLOWING

PRECAUTIONS.

MAIN PIPING CONNECTIONS

NOTE

Refer to warnings and cautions on page 3 before

attempting installation. All piping must comply

with local codes, ordinances, and/or national fuel

gas codes.

1. Shut o power to the unit and install Lock-

Out tag on all disconnects and breakers.

2. Turn o main gas supply line valve.

3. Mark all wires going to the old valve with the

terminal description that they are attached

to.

4. If replacing an existing valve, disconnect all

plumbing and electrical connections from the

old control.

5. The control may be installed in any orienta-

tion except upside down (see gure 1). The

arrow on the valve indicates the direction of

gas ow through the control.

6. You should use new pipe that is properly

chamfered, reamed, and free of burrs and

chips. If you are using old pipe, be sure it is

clean and free of rust, scale, burrs, chips, and

old pipe joint compound.

All piping must comply with local codes, ordinances,

and/or national fuel gas codes.

NOTE

Figure 3. Typical Gas Valve Piping

7. Apply pipe joint compound (pipe dope) that

is approved for all gases, only to the male

threads of the pipe joints. DO NOT apply

compound to the rst two threads (see gure

3for typical piping connections).

8. Install gas valve by holding inlet boss with ad-

justable wrench. Do not tighten excessively,

as this may damage the valve (Torque: 375

in-lb maximum). Do not cross-thread during

installation as this may damage the valve.

9. If the original gas valve has a barbed hose

tting, install pressure tube on barbed hose

tting of the replacement valve. Ensure that

the pressure tube will not kink.

10. Do not remove barbed hose tting from

replacement valve even if the original valve

does not have it.

11. Some applications will require modication of

the pilot tube.

12. See SYSTEM WIRING when making electrical

connections. Connect wires per Fig. 4Diagram

and Fig. 5Chart.

13. After installation is complete, check the

operation of the unit and, with main burners

ring, check all joints for leaks using a leak

detection solution. Retighten all joints where

bubbles appear. DO NOT USE OPEN FLAME

TO CHECK FOR LEAKS

INSTALLATION

NOTE

All wiring should be installed in accordance with

local and national electrical codes and ordinances.

Always check that the electrical power supply used

agrees with the voltage and frequency shown on

the gas control.

Figure 7. Gas Valve, Side

Pilot Gas Connection

Install tting into pilot gas outlet (see Fig. 2),turning

until nger-tight. Insert clean, deburred tubing all

the way through the tting. While holding the tubing

securely, slowly tighten tting until you feel a slight

"give." Tighten the tting an additional 1-1/2 turns.

Conversion from Natural to L.P. Gas. Refer to

conversion kit installation instructions.

Outlet Pressure Adjustment

This control is shipped from the factory with the

regulator set to 3.5" W.C. (Natural gas full ow). If

required, the regulator can be adjusted for outlet

pressures normally ranging from 2.5 to 5" W.C.

(natural gas) or 7.5 to 12" W.C. (L.P. gas). Do not

force the adjusting screw beyond the limits that

it can easily be adjusted.

Inlet/Outlet pressure test ports are 1/8" NPT (see

Fig. 2). For testing pressure, the outlet pressure

tap plug will need to be removed and a separate

hose tting installed. After testing pressure with a

manometer remove hose tting and re-install plug.

Tighten to 60 in-lb max.

INSTALLATION

1. Attach the manometer to the outlet pressure

tap of the valve.

2. Energize system to ignite main burner.

3. Remove barbed hose tting.

4. To DECREASE outlet pressure, turn the

adjusting screw (beneath the barbed hose

tting) counterclockwise.

To INCREASE outlet pressure, turn the

adjusting screw clockwise.

5. Replace the barbed hose tting. Cycle the

valve two or three times to verify regulator

setting.

Pilot Gas Adjustment

Thiscontrolwasfactorypresetandwillnotnormally

require additional adjustment of pilot ame.

If the pilot ame requires adjustment, remove the

pilot adjusting cover screw and gasket (see Fig. 6).

To REDUCE pilot ame, turn the pilot adjust screw

(beneaththecover screw)clockwise.To INCREASE

pilot ame, turn the pilot adjust screw counter-

clockwise. Replace gasket and tighten cover screw.

FOR YOUR SAFETY READ BEFORE OPERATING

A. This appliance is equipped with an intermittent ignition device which automatically lights the

appliance. Do not try to light the pilot by hand.

B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the

oor because some gas is heavier than air and will settle on the oor.

FORYOUR SAFETY

“WHAT TO DO IFYOU 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 neighbor’s phone. Follow the gas supplier’s

instructions.

• If you cannot reach your gas supplier, call the re department.

C. Do not use this appliance if any part has been under water. Immediately call a qualied 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.
