The following directions may vary, depending on regional or national directives.
Applicable legislation in the country in which the stove is being installed must always be respected.
If in doubt, contact your authorised Heta dealer.
4.6. The stove’s flue gas system
The flue gas system is dependent on a slight underpressure in th e combustion chamber, and it is
very important that the chimney exhausts to outside air and not to an enclosed or semi-enclosed
room such as a garage, corridor, attic or anywhere else where the flue gases could become
concentrated.
The chimney must always be installed in accordance with national and regional
regulations
4.7. Chimney draught.
Operation of the Greenfire pellet stove is partly independent of the chimney draught, as the flue
gas vacuum pump assists in removing smoke from the combustion chamber. However, if there is a
strong chimney draught, we recommend a draught stabiliser be installed. Otherwise the chimney
will overrun the flue vacuum pump, resulting in too much combustion. The stove operates best with
a chimney draught of 11 pascals (used for testing/approval) in a
chimney with a diameter of
80 mm
4.8. External air supply.
In hermetically closed environments with little air replacement it can be difficult to supply enough air
for the combustion and it may be necessary to supply extra air to the room.
4.9. No ignition in the burn pot.
During the ignition phase, it may be the case that the stove fails to develop a flame.
If the stove fails to ignite, the control system will shut down the stove and report an error (no pellets)
(See section 8.6.5.)
