HORIZONTAL AIR TERMINAL INSTALLATION
1. Cut or frame a hole in an exterior wall with a mini-
mum opening of (9.5" x 10.5" BGD36CF) or (10.5"
x 11.5" BGD42CF). Secure the fi restop spacer over
the opening to the interior wall.
2. Stretch the exhaust to the required length taking
into account the additional length needed for the
fi nished wall surface. Slip the liner a minimum of 2"
over the inner sleeve of the air terminal and secure
with 3 #8 screws. Apply a heavy bead of the high
temperature sealant (not supplied).
3. Using the air intake vent pipe, slide over the outer
combustion air sleeve of the air terminal and secure
with 3 #8 screws. Seal as before.

5. Apply a heavy bead of the high temperature sealant
to the inside of the exhaust approximately 1" from the
end. Slip the liner a minimum of 2" over the fi replace
vent collar and secure with 3 #8 screws.
6. Using the air intake vent pipe, apply sealant, slide
a minimum of 2" over the fi replace combustion air
collar and secure with 3 #8 screws.
7. If more liner needs to be used to reach the fi re-
place, couple them together as illustrated. The vent
system must be supported approximately every 3 feet
for both vertical and horizontal runs. Use noncombus-
tible strapping to maintain the minimum 1" clearance
to combustibles.
8. BGD42CF ONLY: The
heat sheild must be installed
only when terminating
horizontally with no verti-
cal rise. Remove the two
screws nearest the vent
collars on the top of the fi re-
place. Align the vent heat
shild (supplied) and secure.

to the authority having jurisdiction or
the optional roof support.
2. Stretch the exhaust to the required
length. Slip the liner a minimum of
2" over the inner sleeve of the air
terminal and secure with 3 #8 screws.
Seal using a heavy bead of the high
temperature sealant.
3. Repeat using air intake vent pipe.
4. Thread the air terminal pipe as-
sembly down through the roof. The
air terminal must be located vertically and plumb.
Attach the air terminal assembly to the roof support,
ensuring that a minimum 16" of air terminal will
penetrate the roof when fastened.
DO NOT CLAMP THE FLEXIBLE ALU-
MINIUM LINER.
