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

130102- 1 GF 370 DV MV 2/22

Horizontal Termination


Minimum vertical rise from the vent collar is a 24"
section vent pipe. See fig. 6.5. 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. 6.6 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. 6.7.
 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. 6.8.
 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. 6.9.
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.
