IMPORTANT
For ease of installation, it is recommended that none of the joint(s) in the
vent-air intake system are located inside a wall. However, if a joint does
end up inside a wall, conduct the following steps before installing the five
(5) inch (12.7 cm) diameter telescopic tube(s) into the flared end of the five
(5) inch (12.7 cm) diameter elbow. Drill three (3) 1/8 inch diameter holes,
120
o apart, through the five (5) inch (12.7 cm) diameter telescopic tube(s)
at the joint that will be located inside the wall. Fasten the joint with three
(3) #8 sheet metal screws (supplied). Apply a sufficient amount of the
supplied RTV silicone sealant to seal the joint.
