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

139647_29 GF 370 DV II IPI 10/23

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.

A vent shall not terminate where it could cause
hazardous frost or ice accumulations on adjacent
property surfaces.
