THROUGH THE WALL VENTING: (HORIZONTAL VENTING WITH
CONCENTRIC VENT).
Cut one 4 5/8 in. (11.7 cm) diameter hole in the wall at the point where the vent
connector is going to pass through the wall. Use the proper cement to secure
the vent terminal to the vent connector. Use the proper cement and assembly
procedures to secure the vent connector joints between the terminal and the
blower outlet. Provide support brackets for every 5 feet (1.5 m) of horizontal
vent.
When using the concentric vent terminal the maximum vent length is
reduced by 20 feet.
