PLEASE NOTE:
Initial Break-in
It is normal for smoke and odor to occur during the initial stages
of operation, depending upon temperatures generated over
time. This curing condition can be alleviated by promoting fresh
air circulation within the immediate vicinity of the appliance.
Operational Sounds
Please be aware that cast iron and steel components expand
and contract with temperature fluctuations that are often
accompanied by “creaking” or “pinging” sounds. This is the result
of natural thermal activity.
The optional blower fan will also
generate a slight hum at the low
setting and progressively increase
with the velocity of forced air.

5. Installation
Stove Location
In selecting a location for the stove, consider the following
points:
1) Heat distribution
2) Vent termination requirements
3) Gas supply routing
4) Trac areas, furniture, draperies, etc.
This stove may be located on or near conventional
construction materials, however, proper clearance to
combustibles must be maintained in order to provide
adequate air circulation around the appliance. Also, it is
important to provide adequate access around the stove for
servicing and proper operation.
The clearances specified in this manual are the
minimum requirements established as a result of safety
testing. A combustible material is anything that can burn;
i.e. sheet rock , wall paper, wood, fabrics, etc. These
surfaces are not limited to those that are visible and
also include materials that may be located behind non-
combustible materials.
If you are not sure of the combustible nature of a
material, consult your local fire ocials. “Fire-resistant”
materials are considered to be combustible. They may be
dicult to ignite, but will burn. “Fire -rated” sheet rock is
also considered combustible.

6. Venting
Requirements
There are three types of venting configurations approved
for use with this appliance:
• Vertical Venting / Vertical Termination
• Vertical Venting / Horizontal Termination
• Horizontal Venting / Snorkel Termination
This appliance is approved for use with the 4/6 direct
vent systems manufactured by the companies listed on
page 8. Use parts of one manufacturer only - DO NOT
MIX VENT COMPONENTS FROM DIFFERENT
MANUFACTURERS WITHIN THE SAME SYSTEM.
Installation of any components not manufactured
or approved by Jøtul or failure to meet all clearance
requirements will void all warranties and could result in
property damage or bodily injury.
The approved vent configurations described in this
manual are derived from extensive testing under controlled
laboratory conditions. Gas appliance performance can be
negatively aected by variables present in the installation
environment, i.e.; atmospheric pressure, strong prevailing
winds, adjacent structures and trees, snow accumulation,
etc. These conditions should be taken into consideration
by the installer and stove owner when planning the vent
system design.

GAS VENT HEIGHT: In no case shall any discharge
opening on the cap be less than 18” (457 mm) horizon-
tally from the roof surface. See fig. 6.4.
Maximum Vent Height: 35 ft. above the appliance.
Vertical Venting and Termination
The Jøtul GF 370 DV MV can be vertically vented
through a roof or ceiling. Follow these guidelines
Steep roofs, nearby trees, or predominantly windy
conditions, can promote poor draft or down draft
conditions. In such cases, an increase to the height of
the vent may improve performance.
If an oset or elbow is necessary in the vertical rise, the
vent pipe must be supported every three feet to avoid excessive
stress on the osets. Use listed Wall Straps from any of the
approved vent suppliers.
A maximum of two 90° or four 45° elbows may be
used in a vertical termination. Whenever possible, use
45° elbows instead of 90° elbows as they oer less
restriction to the flow of flue gases and intake air.
A listed firestop is required at any floor penetration.
The opening should be framed in according to the
manufacturer’s instructions.
Always maintain a minimum 1" clearance from all sides
of the vertical vent system to any combustible material.
Minimum vertical termination height: 6 ft. of vent
pipe.

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 oer 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 Stando 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.

Intake Air Adjustment
An Intake Air shutter plate allows further burner adjustment
for taller vent runs. It is located under the firebox floor and is
set fully open at the factory. See fig. 6.12.
The shutter has an adjustment range of 1 inch.
To change the setting, loosen the wingnut and slide the
gasketed shutter stem backward to the half or fully closed
positions, depending on which vent zone is appropriate.
Retighten the wingnut before lighting the burner to seal
the gasket. Allow the flame pattern to settle in for 10- 15
minutes between each setting change.

Figure 6.11. Exhaust Restrictor settings
Figure 6.10. The Exhaust Restrictor is located within the vent
adaptor collar.
Exhaust Restrictor Adjustment
1. Remove the Trim Rings from the Top Plate.
2. Loosen the locking screw and turn the restrictor pivot
plate to the appropriate indicator point as specified in the
vent window diagram, figure 6.13. After the burner has
been operating for 15 minutes, make any further adjust-
ment in 1/8” increments until the desired flame picture
is achieved. Do not exceed the fully closed setting as
shown in fig. 6.11.
Operate the burner for 10-15 minutes between addi-
tional adjustments.
3. Tighten the locking screw and replace the Trim Rings.
Vent Restriction Adjustments
The Jøtul GF 370 DV MV features adjustment controls
for both intake air and exhaust to accommodate a variety
of conditions that result from variables inherent in the
vent configuration and environment. Both controls can be
accessed from outside the firebox to allow the burner to be
“dialed-in” under operation. See figures 6.10 and 6.12.
Use the Vent Termination Diagram, fig. 6.13, to
determine which zone your vent termination falls within
and make the appropriate exhaust and air intake setting
adjustments. Use these settings as general guidelines to start
from. The final settings will ultimately be determined by the
individual characteristics of your particular installation.
There are no hard and fast rules.
Figure 6.12. Air intake shutter location.
Exhaust Vent Restriction
Exhaust restriction prevents overly strong draft that can
interfere with pilot function, cause poor combustion or
a weak flame picture. The shutter is set in the fully open
position at the factory. The final position of the restriction
shutter is determined by where the vent termination falls
within the vent window diagram.
For example, if the vent rise is 20 feet and includes one
elbow in a horizontal run of 5 feet, the appropriate exhaust
setting will be Full Restriction.

A maximum of two 90°
or four 45° elbows may
be used. Whenever
possible, use 45° elbows
instead of 90° elbows as
these oer less restriction
to the flow of flue gases
and intake air.
Reduce the overall
horizontal run by 5 feet
for each additional 45°
and 90° elbow.
When two or more
elbows are used in a
horizontal run, a less
restricted setting may
be more eective
than that indicated by

diagram.
Colinear Venting: Zone
A is reccommended for
all Co-linear vent runs.

2. Connecting the Gas Supply
Gas Supply Requirements
ALL INSTALLATIONS MUST COMPLY WITH LO-
CAL CODE OR IN THE ABSENCE OF LOCAL CODE,
MUST COMPLY WITH THE MOST RECENT EDITION
OF THE NATIONAL FUEL GAS CODE ANSI Z223.1/
NFPA 54 OR CAN-B149.
Shut-o Valve
All codes require a gas shut-o valve (gas cock) and
union to be installed in the supply line within 6 feet of the
appliance. This allows for the disconnection of the stove for
servicing and maintenance. See Fig. 7.2.
A THANDLE GAS SHUTOFF VALVE IS
REQUIRED IN MASSACHUSETTS IN COM
PLIANCE WITH CODE 248CMR.
THIS PRODUCT MUST BE INSTALLED BY
A LICENSED MASTER OR JOURNEYMAN
PLUMBER OR GASFITTER WHEN
INSTALLED IN THE COMMONWEALTH OF
MASSACHUSETTS.
The stove and gas control valve must be disconnected
from the gas supply piping during any pressure testing of the
system at test pressures in excess of 1/2 psig. For pressures
lower than 1/2 psig, isolate the gas supply by closing the
manual shut-o valve.
Control Valve Connection
The gas supply line connection to the stove flex line
can be made at the rear of the base plate or through the
floor. The gas supply line should be a minimum 3/8” inside
diameter, or the appropriate size to provide sucient gas
pressure to the valve regardless of the input setting.
The use of flexible gas appliance connectors is
acceptable in many areas in the U.S. In Canada, methods
vary depending on local code. If local codes permit, use
flexible gas line for ease of installation and service. For those
locales where flexible gas lines are not permitted, use the
3/8” iron fitting to make the connection at the top side of
the Control Valve. See fig. 7.2.
Secure all joints tightly using appropriate tools and
sealing compounds (for propane units, be sure to use com-
pounds that are propane resistant). Turn on gas supply and
test for gas leaks using a 50/50 soapy water solution or a
gas detector.

Soap Solution Leak Test
• Mix a 50-50 solution of water and dish soap.
• Light appliance - see lighting instructions on the back
cover of this manual or on the rating plate.
• Brush or spray all joints and connections with the soapy
water solution.
• If bubbles appear at any connection or seam or a gas
odor is detected, immediately turn gas control knob to
the OFF position.
Tighten or reconnect the leaking joint and retest for any
gas leaks.
The line must be disconnected from the gas supply line
by closing the main supply manual gas shut-o valve (gas
cock) during any pressure testing of the gas supply piping
system that is equal to or exceeds pressures of 1/2 psig (3.5
kPa).
4. Testing Gas Pressure
Proper gas pressure provides a consistent flow of gas to
the appliance and is instrumental in checking for gas leaks.
There are two pressure test points on the front of the stove
control valve where test gauge connections are made. See
Fig. 7.3. Gauge connections are identified by:
• E for inlet or supply pressure ( the amount of gas com-
ing to the valve.)
• A for manifold pressure (the amount of gas that is com-
ing out of the valve to the burner.)
WARNING
DO NOT ALLOW THE INLET GAS PRES
SURE TO EXCEED 14.0” WC OR 1/2 PSIG
AS SERIOUS DAMAGE TO THE VALVE MAY
RESULT.
NEVER USE AN OPEN FLAME TO CHECK FOR
GAS LEAKS.
ALWAYS REFER TO THE LIGHTING INSTRUC
TIONS ON THE INSIDE BACK COVER OF THIS
MANUAL WHEN LIGHTING THE STOVE.

Symptoms of incorrect gas pressure include:
Insucient gas pressure:
• Small pilot flame which can result in insucient milli-
volts.
• Little variation in flame picture between HI and LO
regulator settings.
• Insucient gas to support more than one appliance caus-
ing nuisance outages or gas surges.
Excessive gas pressure:
• Permanent damage to valve causing complete appliance
shut down.
• Too large a pilot flame resulting in overheating of the
power generator and consequent shut down.
• Sooting due to impingement and/or incorrect fuel to air
mix.

6. High Altitude Adjustment
The decreased atmospheric pressure of higher altitudes af-
fects heat value of gaseous fuels. Most gas suppliers derate
the gas intended for use at elevations above 2000 feet.
Check with your gas supplier before performing derate
adjustment to the burner.
This appliance may be adjusted for altitude over 2000 ft.
(610 - 1371 m) for natural gas.
If the gas supplier does not derate fuels, install High Alti-
tude Adjustment Kit 156822 for Natural gas.
DO NOT DERATE FOR PROPANE.
U.S & Canada per
ANSI Z21.88-2019•CSA 2.33-2019, CAN/CGA 2.17
For natural gas installations from 610-1370 meters
(2000-4500 ft.) the orifice size (DMS) is #39. See
data plate for additional information. For high altitude
installations consult the local gas distributor or the
authority having jurisdiction for proper rating methods.
If the installer must convert the unit to adjust for varying
altitudes, the information sticker must be filled out and
applied to the appliance at the time of the conversion.
