P I L O T  
compact package the functions of 3-position gas cock, a  
main gas valve and a pressure regulator. The pilot outlet  
is plugged, but will accept a 14” pilot line connection. This  
control can be mounted in any orientation except upside  
down.  
To permit replacement of a variety of valve sizes, this  
controlisfurnishedwiththreereducerbushings(two34to  
12” and one 12” to 38”). Also included is a conversion kit  
which allows this valve to be used at regulator settings of  
4.2” W.C. to 11.0” W.C.

NOTE  
All piping must comply with local codes, ordinances,  
and/or national fuel gas codes.  
1. Turn off electrical power to the system at the fuse box  
or circuit breaker. Also turn off the main gas supply.

4. 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.

5. Apply pipe joint compound (pipe dope) or teflon tape  
that is approved for all gases, only to the male  
threads of the pipe joints. DO NOT apply com-  
pound or teflon tape to the first two threads (see fig. 1  
for typical piping connections).

6. If you are using a vise or open-end wrench to hold the  
valve while installing piping, do not tighten exces-  
sively, as this may damage the valve.  
7. If additional clearance for the gas cock knob is re-  
quired when installing the new valve in an existing  
system, rotate the knob to the position between ON  
and OFF. Depress the knob while turning the valve.  
The knob will depress only while in this position.

If the pilot flame is low and does not engulf the bulb of the  
mercury flame sensor, the system will not energize the

To adjust the pilot gas pressure, remove the cover screw  
(see fig. 5). To REDUCE pilot pressure, turn the pilot  
adjust screw (beneath the cover screw) clockwise. To  
INCREASE pilot pressure, turn the pilot adjust screw  
counterclockwise. Replace and tighten cover screw.

PILOT LIGHTING INSTRUCTIONS  
AND PRECAUTIONS  
FOR YOUR SAFETY READ BEFORE LIGHTING  
If you do not follow these instructions exactly, a fire or explosion  
may result causing property damage, personal injury or loss of life.

for gas. Be sure to smell next to the floor because some  
gas is heavier than air and will settle on the floor.  
C. Use only your hand to push in or turn the gas control knob.  
Never use tools. If the knob will not push in or turn by  
hand, don't try to repair it; call a qualified service techni-  
cian. Force or attempted repair may result in a fire of  
explosion.
