VERTICAL TERMINATION
WITH NO OFFSETS
Min. Vertical Pipe Length: 5 feet
Max. Vertical Pipe Length: 25
feet
VERTICAL TERMINATION
WITH 2 OFFSETS
Min. Vertical Pipe From Appliance to first
offset: 2 feet (*see note).
Min. Total Vertical Pipe Length: 5 feet
Max. Total Vertical Pipe Length: 25 feet
HORIZONTAL TERMINATION
WITH 1 OFFSET
Min. Vertical Pipe From Appliance to offset:
2 feet (*see note).
Max. Vertical Pipe Length: 25 feet
Maximum total offsets allowed: Not to exceed 180 degrees.
Maximum allowable horizontal pipe run is 16 feet.
With 2 feet of vertical pipe installed from the appliance (* see note), a 2 foot maximum horizontal run allowed. For installations with
more than 2 feet of vertical pipe, calculate allowable horizontal run as indicated in applicable illustration above.
See page 10 for Vent Termination Requirements.
Also see pipe manufacturers instructions for additional vent installation requirements.
Horizontal vent clearances
: 3“ minimum top 1“ minimum on bottom and sidewalls.
Vertical vent clearances
: 1” minimum.
Install vent support brackets every 4 feet of vertical pipe unless otherwise specified by vent manufacturer.
* Note: If using Propane Gas (LP), it may be necessary to install (as a minimum) 3 feet of vertical pipe from the appliance prior to an
offset to ensure optimum product performance. This may be necessary due to variations in vent configuration and other numerous
factors which affect exhaust flow and air delivery such as BTU value, ambient temperature, wind conditions, altitude, etc.
For every 1 feet of
vertical pipe (from
unit to first offset), 2
feet of horizontal
run is allowed (not
to exceed 16 ft.
Example – with a 6’ ver-
tical pipe off unit, 12’ of
horiz
o
ntal run is allowed.
At 2’ Min. V
