Pilot Gas Connection
Install fitting into pilot gas outlet (see Fig. 7), turning until finger-
tight. Insert clean, deburred tubing all the way through the fitting.
While holding the tubing securely, slowly tighten fitting until you
feel a slight "give." Tighten the fitting an additional 1-1/2 turns.
Conversion from Natural to L.P. Gas. Refer to conver-
sion 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 flow). 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. 7). For
testing pressure, the outlet pressure tap plug will need to be
removed and a separate hose fitting installed. After testing pres-
sure with a manometer remove hose fitting and re-install plug.
Tighten to 60 in-lb max.
1. Attach the manometer to the outlet pressure tap of the
valve.
2. Energize system to ignite main burner.
3. Remove barbed hose fitting.
4. To DECREASE outlet pressure, turn the adjusting screw
(beneath the barbed hose fitting) counterclockwise.
To INCREASE outlet pressure, turn the adjusting screw
clockwise.
5. Replace the barbed hose fitting. Cycle the valve two or
three times to verify regulator setting.
Pilot Gas Adjustment
This control was factory preset and will not normally require
additional adjustment of pilot flame.
If the pilot flame requires adjustment, remove the pilot adjusting
cover screw and gasket (see Fig. 5). To REDUCE pilot flame,
turn the pilot adjust screw (beneath the cover screw) clockwise.
To INCREASE pilot flame, turn the pilot adjust screw counter-
clockwise. Replace gasket and tighten cover screw.
