Supporting the exhaust vent system and the use of an external condensate trap

External condensate traps

B A condensate trap must be used in any sidewall exhaust vent installations when the total vent length is 5 ft (1.5 m) OR the vent pipe passes through an unheated space (below 60F). See diagram below for connecting a condensate tube.

B A condensate trap must be used for any vertical exhaust installations. See diagram below for connecting a condensate tube.

BWhen installing the condensate tubing at the exhaust collar (see diagram below), be sure to form a trap by means of a 3" (76.2 mm) loop filled with water. This tube must be 3/8" ID high temperature silicone for at least the first 6 inches (152 mm) and attached with a gear clamp or hose clamp. The condensate must be disposed of according to local regulations.
