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 ft (1.5 m) of horizontal vent.
IMPORTANT
When using the vent terminal configuration shown in 8c, the extra elbows must
be accounted for in the total vent length. See Table 5 or Table 6.
IMPORTANT
When using the concentric vent terminal, the maximum vent length is reduced
by 10 ft. See Figure 9a.
