3.0 Before installation

3.1 Distance to inflammable material
See fig. 1
3.2 Foundations
Make sure the floor is suitable for the entire installation. See «2.0
Technical Data» for specified weight.
Remember: If using a steel chimney that rests on the insert, the
weight of the steel chimney must be taken into account.
NB: It is extremely important to ensure that the product is stable.
It must be installed on a completely inflexible floor.
We recommend the removal of any flooring that is not attached
to the foundation («floating floors») from the installation area.
3.3 Floor plate
A plate made of steel or other suitable non-combustible material
is placed in front of the fireplace and possibly under the entire
installation.
The floor plate must comply with national laws and regulations.
Contact your local building authorities regarding restrictions and
installation requirements.

3.4 Air supply

There must be a flow of air between the burn chamber and the
surround. This is to prevent too much heat building up inside the
surround.
NB: It is extremely important not to cover air openings. See fig. 1
for distances.
3.5 External air
A flexible supply hose allowing external air to be fed directly into
the product can be passed through:
• The opening in the rear plate
• The bottom plate's knockout.
• See the manual for the product.
3.6 Steel chimney
If a top-mounted steel chimney is used, an uninsulated pipe is
fitted from the burn chamber to approximately 10 mm through
the top grate. Make sure that the gasket is properly seated
between the flue pipe and the smoke outlet. Then fit the steel
chimney in accordance with the chimney supplier's installation
instructions.

4.0 Installation
The product is heavy! Ensure you have help when positioning
and installing it.
The product comes with three manuals:
1. General use and maintenance instructions.
2. Jøtul FS 380 Series (surround).
3. Jøtul F 370 Series (burn chamber).
4.1 Preparations
The basic product comes in three packages:
1. Burn chamber.
2. Steel surrounding set.
3. Leg console.
NB: Check that there is no visible damage to the product when you
unpack it, and make sure that the control handles move freely.
Before installation, it is necessary to decide on:
• Possible use and location of external air supply. See separate
manual for installation.
NB: The burn plates are made of a porous material (yellow
vermiculite) and may be damaged if they are handled roughly.
1. When the burn chamber is unpacked, the burn plates, baffle
plate, exhaust deflector, base plate, ash pan and riddling grate
are removed. Also remove the small side burn plates and
gasket for flue pipe which are in the ash pan.
2. Lift off the top plate with the top grid and bowl. The top plate
is not to be used.
4. Check that the operating handles work.
5. Spread out the cardboard packaging on the floor, and put a
wooden pallet upon it. Lay the stove carefully on its side. See
fig. 3.
4.2 Chimney and flue pipe
• The fireplace can be connected to chimneys and flue pipes
approved for solid fuel fireplaces with flue gas temperatures
as specified in «2.0 Technical Data».
• The cross-section of the chimney must be at least that of the
flue pipe. When calculating the correct chimney cross-section,
refer to «2.0 Technical Data».
• Several solid fuel fireplaces can be connected to the same
chimney system if the chimney cross-section is adequate.
Contact your local building authorities regarding restrictions
and installation requirements.
• Connection to the chimney must be performed in accordance
with the installation instructions of the chimney supplier.
• Make sure that the flue pipe rises all the way up to the
chimney.
