INSTALLATION
HORIZONTAL INSTALLATIONS
1)
Set the unit in its desired location. Check to determine if
wall studs are in the way when the ven^ng system Is
attached, if this Is the case, you may want to adjust the
location of the unit.
2)
Assemble the desired combination of pipe and elbow to
the appliance adaptor with pipe seams oriented down.
Offset the pipe seams as double seams in one place will
cause the outer pipe to take an oval shape. Kit comes
complete with 18" of straight vent - 6-5/8'' dia. black outer
pipe and 4" dia. inner vent.
3)
With the pipe attached to the stove, slide the stove into its
correct location, and mark the wall for a
9-1/2" {inside dimensions) round hole. The center of the
round hole should line up with the centerline of the
horizontal pipe, as shown in diagram 1. Cut and frame the
9-1/2 round hole in the exterior wall where the vent will be
terminated. If the wail being penetrated is constructed of
non-combustible material, i.e. masonry block or concrete,
a 7" diameter hole is acceptable.
Diagram 1
Note:
a)
The horizontal run of vent should have a 1/4 Inch rise for
every 1 foot of run towards the termination. Never allow
the vent to run downward. This could cause high temper¬
atures and may present the possibility of a fire.
b)
The location of the horizontal vent termination on an
exterior wall must meet all local and national building
codes, and must not be blocked or obstructed. For Exter¬
nal Vent Terminal Locations, see diagram on page 10.
c)
Snorkel Terminations:
For installations requiring a vertical rise on the exterior of
the building, 14-inch and 36-inch tali Snorkel Termina¬
tions as shown in Dia. 2 are available, as well as the
standard Riser Vent, see Dia. 3. Follow the same instal¬
lation procedures as used for standard Horizontal Termi¬
nation. NEVER install the snorkel upside down.
Below Grade installation
If the Snorkel T ermination must be installed below grade,
i.e. basement application, proper drainage must be pro¬
vided to prevent water from entering the Snorkel Termi¬
nation. Refer to Dia. 4. Do not attempt to enclose the
Snorkel within the wall, or any other type of enclosure.
Diagram 4
4)
Install wall penetration heat shield in the center of the 9-
1/2" round hole and attach with wood screws. The four
wood screws provided should be replaced with appropri¬
ate fasteners for stucco, brick, concrete, or other types of
sidings. Dia. 5.
