Horizontal Termination - Jøtul GF 305 DV IPI Installation And Operation Instructions Manual

Horizontal Termination

Any horizontal termination must fall within the shaded

portion of the vent window matrix shown in fig. 6.3.
Any horizontally terminated vent run must include a

minimum vertical rise off the stove. See fig. 6.6.
SNORKEL TERMINATION:

14" (356mm) or 36" (914mm) snorkel termination is
approved in conformance with the vent specifications
published in this manual. See figs. 6.3 and 6.6.
The snorkel termination must comply with grade and
building clearance requirements per local and national
building codes. See fig. 6.7.
Horizontal termination requirements:

1) Maximum vertical run is 30 ft. (9.144m)
2) Maximum horizontal run is 20 ft. (3.05 m)
Up to two 45° elbows or one 90° elbow may be used in

addition to the first elbow. The horizontal run must be
reduced by 5 feet for each additional elbow, whether
45° or 90°.
The horizontal termination cap must maintain a 3"

clearance to any overhead combustible projections
2 1/2" or less. It must also maintain 12" clearance from
projections exceeding 2 1/2". See fig. 6.8.
Wall Cut-out Opening: A minimum 10" X 10" (250 mm

x 250 mm) square hole is required for proper pipe
clearances through a combustible wall.
Horizontal Vent Pipe Clearance to Combustible

Material:
From Top: 2" (51 mm)
From Sides: 1" (25 mm)
DO NOT FILL AIR SPACE WITH ANY TYPE OF INSULATION.
Any horizontal run of vent must be level or have a

1/4 in. rise for every foot of run toward the termination
cap. NEVER ALLOW THE VENTING TO RUN DOWNWARD
FROM STOVE TO TERMINATION; A DOWNWARD VENT
RUN TRAPS HEAT AND CREATES A FIRE HAZARD.
Install a Vinyl Siding Standoff (M&G Dura-Vent #950)

between the vent termination and an exterior wall
covered by vinyl siding material to prevent potential
heat damage to the siding.
A direct vent terminal may not be recessed into a wall

or siding.

Figure 6.6. Minimum vent required for horizontal
termination.
A: Any horizontally terminated vent run must include a
minimum vertical rise (A) off the stove:
Natural Gas - Min. 18 in. (45.7 cm)*
Propane - Min. 24 in. (61 cm)
* We strongly suggest a minimum 24 in. vertical rise for
any horizontally terminated vent run.
B: At those minimum vertical runs, the horizontal run (B)
must not exceed:
Natural Gas - Max. 6 in. (15.2 cm)
Propane - Max. 36 in. (91.44 cm)
RE-INSTALL THE TOP PLATE BEFORE
CONNECTING VENT TO THE STOVE.
