Venting & air — general
Venting and air piping — DIRECT VENT ONLY — OPTIONS and PIPING LIMITS
The table below lists the acceptable vent/air pipe terminations described in this manual. Follow all instructions provided to install the
vent/air system.
For these applications, use ONLY the manufacturers' parts listed and follow all instructions provided by the pipe manufacturer.
(All applications include allowance for the termination fittings plus one elbow in air piping and one elbow in vent piping).
See Figure 27, page 23 for material specifications | See Figure 125, page 137 for part/kit numbers
If using 2" pipe, provide 3"x 2" tapered reducers at boiler connections and at Weil-McLain vent/air cap or at concentric terminations.
Boilers will derate as vent/air pipe length increases — see rating data on Figure 138, page 149 for derate amounts.

Maximum vent and air pipe length (for each)
80/110/150 - 2" & 3" = 100 feet
199 - 3" = 100 feet / 199 -2" = 50 feet
(Minimum length for all applications is 2 feet)
