cm) from the end of the three (3) inch (7.6 cm) diameter tube that is part
of the vent-air intake terminal. Slide the direct vent-air intake terminal into
the three (3) inch (7.6 cm) diameter telescopic tube that extends through
the wall and position it so it is flush with the outer wall mount plate. Make
sure that the rain guard and the word “HOT” on the end of the direct vent-
air intake terminal are oriented properly. Secure the direct vent-air intake
terminal to the outer wall mount plate and wall with four (4) #10 x 1 inch
screws (supplied). (See Figure 18). Note: Certain construction of walls
may require the use of different type of anchoring means than supplied.
DO NOT modify the direct vent-air intake terminal or outer wall mount
plate.

elbow into the five (5) inch (12.7 cm) diameter telescopic tube(s) and
through the tubes where the small and large sections overlap. Fasten
with three (3) #8 sheet metal screws (supplied). Using the supplied RTV
silicone sealant, apply a sufficient amount to seal all joints. (See Figure
