HORIZONTAL INSTALLATION (cont.)
Step 3.
With the adapter and pipe attached to the stove, slide the stove into its correct location,
maintaining minimum clearance to combustibles, and mark the wall for a 10 x 10 (254mm
x 254mm) square hole. The center of the square hole should line up with the centerline of
the horizontal pipe, as shown in Figure 6. Cut and frame the hole in the exterior wall
where the vent will be terminated. If the wall being penetrated is constructed of
noncombustible material, i.e. masonry block or concrete, a 7 (178mm) diameter hole is
acceptable.
NOTE:
(1)
The horizontal run of vent must be level, or have a ¼ (6mm) rise for every 1 (305mm) of
run towards the termination. Never allow the vent to run downward. This could cause
high temperatures and may present the possibility of a fire.
(2)
The location of the horizontal vent termination on an exterior wall must meet all local and
national building codes, and must not be easily blocked or obstructed.
(3)
For installations requiring a vertical rise on the exterior of the building, 14 (356mm) and
36 (914mm) tall snorkel terminations are available. Follow the same installation
procedures as used for standard horizontal terminations. If the snorkel termination must
be installed below grade (i.e. basement application), proper drainage must be provided to
prevent water from entering the snorkel termination. Do not backfill around snorkel
termination.
NOTE:
Only one
90° elbow is permitted per side wall (horizontal) installation. An additional 45°
elbow is permitted for corner installations.
