CONTROLS
All controls are pre-assembled at the factory. The normal
mani%td pressure should be 3.5" w.c. for Natural Gas and
10" w.c. tbr L.P. Gas. The maximum inlet pressure in the
gas supply pipe should never exceed 7.0" w.c. tSr Natural
Gas or 14" w.c. for L.P. Gas. The minimum inlet pressure
in the gas supply pipe should never be lower than 4.5"
w.c. for Natural Gas or 11" w.c. tbr L.P. Gas.

The appliance is orificed at the factory for elevations up
to 2,000 feet. If installed above 2,000 feet, the BTU input
must be reduced 4% per 1,000 feet. See the tbllowing
orifice chart for the proper orifice %r a specific elevation.
PILOT
ADJUSTMENT
Locate the pilot adjustment screw on the valve. The pilot
flame should surround at least the top 3/8" of the powerpile
(pilot generator) or flame sensor (see Figure 8). The pilot
is unregulated so it will be operating at inlet line pressure
(maximum
7" w.c. for Natural Gas and 11" w.c. %r
Propane Gas). To decrease the pilot flame, turn the screw
clockwise (approximately six full turns to bottom of pilot
light channel) until you produce sufficient flame at the
minimum noise level.
