Below are approved examples of vertical and horizontal venting
installations.
Fig. 13 Horizontal side wall venting installation (single pipe
penetration)
[1] Termination
[2] Minimum above ground or normally expected snow accumulation
level
[3] Appliance
[4] Drain tee
[5] Elbow (note: minimum 1ft of straight vent pipe required)
[6] Horizontal run ¼ " per foot down to termination
[7] Hanger strap
Fig. 14 Horizontal venting installation (combustion air piping not
shown)
[1] Termination
[2] Minimum above ground or normally expected snow accumulation
level
[3] Appliance
[4] Elbow (note: minimum 1ft of straight vent pipe required)
[5] Horizontal run ¼ " per foot down to termination
Fig. 15 Horizontal venting system (concentric vent)
Fig. 16 Horizontal parallel venting system (twin pipe direct vent)
[A] 3 ft minimum
[B] 26 ft with 3" venting
60 ft with 4" venting
Below are approved examples of vertical venting installations.
Important:
Note: Pitch horizontal runs down toward the heater, ¼ " per foot.
WARNING:
▶ Single pipe penetration should be used in non-
freezing climates only!
