INSTALLATION
CONTROLS
All controls are pre-assembled at the factory. The normal
manifold pressure should be 3.5” w.c. for Natural Gas and 10”
w.c. for Propane Gas. The maximum inlet pressure in the gas
supply pipe should never exceed 7.0” w.c. for Natural Gas or
14” w.c. for Propane 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. for Propane Gas.
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 14)
. The pilot
is unregulated so it will be operating at inlet line pressure
(maximum 7” w.c. for Natural Gas and 11” w.c. for 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.
The appliance equipped only for altitudes 0 - 2,000 feet. If
installed above 2,000 feet, the BTU input must be reduced 4%
per 1,000 feet. Orifice change must be completed by a qualified
installer or service technician. See the following orifice chart for
the proper orifice for a specific elevation.
