HORIzONTAL AIR TERMINAL INSTALLATION
1. Cut or frame a hole in an exterior wall with a mini-
mum opening of (9.5" x 0.5" BGD6CF) or (0.5" x .5"
BGD42CF). Secure the firestop 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 finished wall
surface. Slip the liner a minimum of " over the inner sleeve
of the air terminal and secure with  #8 screws. Apply a heavy
bead of the high temperature sealant (not supplied).
3. Using the air intake vent pipe, slide over the outer com-
bustion air sleeve of the air terminal and secure with  #8
screws. Seal as before.

minimum of 2" over the fireplace combustion air collar and
secure with  #8 screws.
7. If more liner needs to be used to reach the fireplace,
couple them together as illustrated. The vent system must
be supported approximately every  feet for both vertical and
horizontal runs. Use noncombustible strapping to maintain the
minimum " clearance to combustibles.
