Horizontal Termination - Jøtul GF 370 DV II Installation And Operation Instructions Manual

139467_03 GF 370 DV II June 2015

Horizontal Termination

Minimum vertical rise from the vent collar is a 24"

section vent pipe. See fig. 9. Minimum horizontal
run is 12" with natural gas and 18" with propane.
A maximum of two 90° or four 45° elbows may

be used in a horizontal termination. Whenever
possible, use 45° elbows instead a 90° elbow as
they offer less restriction to the flow of flue gases
and intake air. Reduce the overall horizontal run
by 5 feet for each additional elbow, whether 45° or
90°.
Snorkel Termination - ( 14" or 36"):

NATURAL GAS ONLY. DO NOT USE SNORKEL
TERMINATION WITH PROPANE FUEL.
A horizontal vent run may be made with a 90°
elbow directly to the rear of the stove only when
terminated by a 14 or 36 inch snorkel cap. Fig. 10
shows the minimum vent pipe requirements.
14" Snorkel: The maximum horizontal vent run
must not exceed a 24" section of pipe and must be
a minimum of 12".
36" Snorkel: The maximum horizontal vent run
must not exceed 5 feet and must be a minimum
of 12".
The termination cap must not be recessed into

the wall or siding. Do not fill air space in wall around
termination cap with any type of insulation.
Wall Cut-out: A minimum 10" X 10" square hole

is adequate for proper pipe clearance through a
wall, provided the vent is positioned to maintain
2" minimum clearance at the top. A 1" minimum
clearance must be maintained to combustible
material around the other sides. See fig. 11.
Any horizontal run of vent must have a 1/4" rise for

every foot of run toward the termination cap.
All horizontal terminations must comply with the

clearance specifications to adjacent structures as
indicated in fig. 12.
Installation of a Vinyl Siding Standoff is required

to prevent damage to vinyl siding between the
vent cap and the exterior wall.
A horizontal termination cap must maintain a 3"

clearance to any overhead combustible projections that
are 2 1/2" or less. It must also maintain a 12" clearance
from projections that exceed 2 1/2". See fig. 13.
Vinyl siding projections require a default clearance of
18" to the vent terminal.
