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.
