EXTERIOR INSTALLATION OF THE VENTING
Attach 5" (127 mm) diameter air inlet tube onto the collar of air
drop assembly. Attach caulked, outside wall mounting plate into the
5" (127 mm) diameter air inlet tube. Flue outlet tube must be
tightly sealed against the heater and vent cap for safe and proper
operation.
NOTE: Flue outlet tube and air inlet tube should be measured and cut to the proper length from the back of the unit to the outside wall
of the house. There should be little to no venting showing on the outside of the house.
(4) #10 x 2 ½”
SCREWS
Place caulking (not provided) beneath the edge of the outside wall
mounting plate. Use additional caulking to correct uneven wall
surface, such as clapboard.
Position the outside wall mounting plate so that 5" (127 mm)
diameter air inlet tube has a slight downward slope to the outside.
The downward slope is necessary to prevent the entry of rainwater.
Attach outside wall mounting plate to exterior wall with (4) #10
x 2 1/2" (63.5 mm) screws provided.
