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).
B A condensate trap must be used for any vertical exhaust installations. See Drain Tee position options in Fig. 19 and Fig. 20.
BWhen installing the condensate tube at the bottom of the drain tee, 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.
The venting materials and accessories
irequired to properly install the water heater are available from CEC and their distributors.
Fig. 17 Horizontal side wall venting installation (combustion air piping not being shown)
A condensate trap (drain tee) must be used in any side wall installation if the total exhaust vent length is greater than or equal to 5 feet (1.5 m).
Fig. 18 Above the roof clearance requirements from rain cap (combustion air piping not being shown)
Fig. 19 Vertical venting installation (combustion air piping not being shown)
A condensate trap (drain tee) must be used for any vertical exhaust vent installation. The condensate trap should be positioned as near to the top of the heater as possible.
