4.2 Wall
Distance to combustible wall protected by
insulation (fig. 1)
The Jøtul I 520 can be installed inside an open structure/surround,
provided that the distance from the wall (both combustible and
non-combustible) is at least 700 mm on the sides with glass,
and at least 362 mm on the sides without glass. These distances
must be observed because of the heat that is transferred onto
the ceiling and adjacent walls (Fig. 1 e and f). With this type of
installation, the convection holes in the front and sides of the
surround can be omitted since there are convection slots in the
top.
Note: Do not place a solid plate on the top of the stove. There
must be at least 750 cm
2
of free air space at the top and at least
500 cm
2
of free opening at the base.
Insulation requirements
When installing the insert in a home-built surround with
combustible walls protected by insulating material, the following
types and thicknesses of insulation can be used:
• 50 mm Jøtul JGFW-5 fireproof board (specific thermal
conductivity = λ value = 0.06 W/mK)
• 50 mm Rockwool Fire Protective Bats (λ value = 0.046 W/mK)
• 150 mm Siporex (λ value = 0.144 W/mK).
Other materials may be used. The insulation properties must
then always be equal to or exceed the thermal resistance* (R)
requirements for the 50 mm Jøtul JGFW-5.
* Thermal resistance (R) is an indication of how well a material
insulates with respect to its thickness. Thermal resistance (R)
is calculated as the thickness (d) of the material divided by the
thermal conductivity of the material. R = d/λ value.
The thermal resistance (R) for the Jøtul JGFW-5 is 0.83 m2*K/W.
Distance to combustible wall protected by
firewall (Fig. 1)
Requirements for regulation firewalls
The firewall must be at least 100 mm thick and made of brick,
concrete or lightweight concrete. Other materials and structures
with satisfactory documentation may also be used.
Contact your local building authorities regarding restrictions and
installation requirements.
Distance to non-inflammable wall
“Non-inflammable wall” here means a non-bearing wall of
continuous brickwork/concrete.
Requirements for fireplace surround
Fireplace surrounds must be made of a non-inflammable material
Note that the entire back wall and, if any, side walls within the
surround must be covered with insulation/firewalls.
If the cowl is built up to the ceiling and the ceiling is of
inflammable material, extra panelling must be installed above
the top of the heating chamber and above the cowl’s vents in
order to prevent the ceiling becoming hot. Use for example:
Rock wool, 100 mm thick, on a steel plate (min. 0.9 mm). See Fig.
1 e and f. Ensure there is adequate ventilation in the top of the
cowl – e.g. a gap under the ceiling.
NB: Remember that it must be possible to sweep and inspect
the installation.
4.3 Air supply
Air must flow between the insert and the brickwork, and it is
extremely important that there is an unimpeded air supply to
the air inlets.
The air inlet dimensions specified in the text are minimum
requirements.
Required air vent sizes (for air circulation):
Base: Minimum of 500 cm
2
free opening.
Top: Minimum of 750 cm
2
free opening.
Note: See fig. 1 e and f
4.4 Ceiling
The fireplace can be fitted with the top edge of the hot air
opening of the surround at least 400 mm below a ceiling of
inflammable material. See Fig. 1 e and f. Ensure there is adequate
ventilation in the top of the cowl – e.g. a gap under the ceiling.
4.5 Chimney
The chimney is the engine that drives the fireplace and it’s
essential to have a good chimney in order for the fireplace to
function properly.
The draught in the chimney creates a vacuum in the stove. This
vacuum draws the smoke out of the stove and takes in air through
the combustion air baffle to fuel the burning process.
The combustion air is also used for the airwash system that keeps
the window clear of soot.
The draught in the chimney is caused by the difference in
temperatures inside and outside the chimney. The greater the
temperature difference, the better the draught in the chimney.
It is therefore important to allow the chimney to reach operating
temperature before adjusting the air vents to restrict combustion
in the stove (a brickwork chimney takes longer to reach operating
temperature than a steel chimney).
It is particularly important to reach operating temperature as
quickly as possible on days on which the draught in the chimney
is poor due to unfavourable wind and weather conditions. Make
sure the fuel ignites as quickly as possible. Practical tip: Chop
the wood into much smaller pieces and use an extra firelighter.
NB: If the stove has not been used for some considerable time, it
is important to check the chimney pipe for blockage.
