Warning: Operate your Jøtul F 400  with the front door fully
open and the firescreen in place or fully closed. A partially
opened door may result in overfiring.  Also, if the door are
left partly open, gas and flame may be drawn out of the
stove opening, creating risks from both fire and smoke.

Jøtul recommends the use of a magnetic stove-top
thermometer to monitor the surface temperature of the
stove.  The optimum surface temperature range for the
most efficient, clean burn  is between 400° and 600°.

Your local building code may require that an outside air
supply be connected to the stove. Jøtul Outside Air Kit 154335
must be used in these installations unless otherwise
specified by the local code official. While the use of outside
air may be beneficial in some installations, in itself, such a
system does not guarantee proper chimney performance.
The Outside Air Kit includes an adapter collar to attach the
air duct to the stove. Installation will require these
additional materials not included in the kit:

1. 3” (80 mm) diameter flexible metallic Air Duct - of

appropriate length to reach from the stove to the
outside of the house.

2. Weatherproof Duct Cap for the duct termination on

the outside of the house.

3. Rodent Screen - no larger than 1/4” (5 mm) mesh.

Outside air should be considered if:
1. The stove does not “draw” steadily. Smoke rollout occurs

when the door are opened. Fuel burns poorly. Backdrafts
occur with or without a fire burning.

2. Other fuel-fired equipment in the house, such as

fireplaces or other heating appliances, smell, do not
operate properly, suffer smoke roll-out when opened,
or back-draft whether or not there is combustion
present.

3.  Opening a window slightly on a calm (windless) day

alleviates any of the above symptoms.

4.  The house is equipped with a well-sealed vapor barrier

and tight fitting windows and/or has any powered
devices that exhaust house air.

5.  There is excessive condensation on the windows in the

winter.

6.  A ventilation system is installed in the house.

If these or other indications suggest that infiltration air is
inadequate to supply sufficient air for the stove, additional
combustion air should be provided from the outdoor.
Outside combustion air can be provided to the appliance
by the following means:

1. Direct connection: The Jøtul F 400  has been tested and

approved for use with the outside air kit listed above.

2.  Indirect method: Outside air is ducted to a point no closer

than (12”) 300 mm from the stove, to avoid affecting

the performance of the appliance.

3. A mechanical ventilation system:     If the house has a

ventilation system (air change or heat recovery):
a. The ventilation system may be able to provide
sufficient combustion makeup air for the solid-fuel
appliance.
b. The homeowner should be informed that the
ventilation system might need to be rebalanced by a
ventilation technician after installation of the appliance.

Note:  Provision of outside air to the stove, directly or
indireclty, may fail to remedy the problems outlined above.
Chimney performance is determined by a variety of
interelating factors which may not be affected by the air
supply. Your local Jøtul authorized dealer is your best resource
for information regarding chimney and stove performance
issues.

Use of the Floor Bracket Kit is required in all mobile home
installations to secure the stove to the floor. Complete
installation instructions and diagrams are supplied with
each Floor Bracket Kit.

A stove rear heat shield has been specifically designed for
the Jøtul F 400  to reduce clearances off the rear of the
stove to combustible materials. Use of the heat shield does
not affect the clearance off the sides of the appliance. 

See

pages 8-9

 for specific clearance requirements. Complete

installation instructions are supplied with the heat shield.

No other type of heat shield may be used on the rear of the
Jøtul F 400 .

The bottom heat shield supplied with your stove has been
specifically designed for the Jøtul F 400 . It is required in all
alcove installations. Use of the bottom heat shield does not
affect the floor protection requirements described on 

page

6

 of this manual.

No other type of heat shield may be used on the bottom of
the Jøtul F 400 .
