Typical Venting
This combustion air intake has a built-in condensate collection
system. Condensate that may collect is drained by field supplied 1/2"
ID tubing. The tubing must be routed to form a trap and water seal
( see Figure 1, p. 32, Figure 2, p. 32, and Figure 3, p. 32).
A field supplied hose clamp is recommended but not be required. The
tubing is not under pressure.
Combustion air piping must be square cut and de-burred for proper
drainage. For side entry combustion inlet applications, ensure the
drain is pointed downwards.
