FIG. 12
Installation of
B-W Gas Vent
for one story
buildings or for
first floor of
multi-story
buildings.
Header plate of
vented wall furnace.
(Also acts as firestop)
Use manufacturer's
method of fastening
pipe to base plate.
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.
STANDING PILOT
Honeywell VR8200H Series
Pilot Adj. Screw
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.
PILOT FLAME ADJUSTMENT
Pilot flame should envelop 3/8 to ½ inch of the tip of the generator.
INSTALLATION
Ceiling plate spacers
to center B-W gas vent
in stud space - nail
securely at both ends.
Plate cut away for full
width of stud space
to provide ventilation.
Studs on 16"
centers.
Sheet metal screw
base plate to header.

FIG. 13
Installation of B-W gas vent
for each subsequent ceiling or
floor level of multi-story
buildings.
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.
