STRAIGHT THROUGH WALL

1) Determine the exact position of the gas stove so that the direct vent
pipe is centered (if possible) between two building framing members.
This will avoid any extra framing.
2) Carefully measure up 23-inches from the finished floor and mark the
center of a 9-inch square or round hole. (See Figure #10)
IMPORTANT: When locating this hole it should be noted that the
bottom of the vent terminal must be a MINIMUM of 12-inches above
grade, the top of the terminal must be a MINIMUM of 24-inches below
combustible material such as a deck or roof overhang and the side
of the terminal must be a MINIMUM of 12-inches away from an
adjacent wall. (See Figure 15)
3) Cut a 9-inch square or round hole through the exterior wall of the
building.
4) Position the wall thimble spacer (WTS) from the inside through the 9-
inch hole . (Figure 10). For walls less than 11-inches thick, the thimble
must be trimmed back flush with the exterior wall.
5) Attach the trim collar to the flanges of the wall thimble with the screws
provided.
6) The coaxial starter pipe (SK 12) may have to be cut to length
depending on the wall thickness and/or rear clearance of the stove.
Measure the wall thickness from the finished trim collar surface to the
exterior mounting surface for the vent terminal. Add 1/4-inches plus
rear clearance to the wall thickness (i.e. rear clearance of 1", add 1
1/4" , rear clearance of 3", add 3 1/4" to wall thickness).
7) Cut both pipes to this length. Do not cut off the crimp-bead off the 5-
inch inner pipe.
8) The vent pipe must be attached to the collars of the gas stove with the
bead end towards the appliance. Slide the inner 5-inch flue pipe over
8
top of the collar up to the crimp-bead and attach with three sheetmetal
screws. Seal the joint with high temperature silicone. Next, slide the
7-inch outer pipe over the 5-inch pipe fully and secure to the pipe collar
with three sheetmetal screws. Assure that the vent pipe is level.
9) Slide the appliance into place, with vent pipe centered in wall pass-
through. When the unit is properly installed, the 7-inch vent pipe will
project 3/4-inch past the outside wall surface and the 5-inch inner pipe
will extend 1-inch past that. The coaxial vent pipe must be level.
10) Install vent terminal according to section VENT TERMINAL INSTAL-
LATION
