FLUEWAY

The stove requires a CE listed pellet vent.So the venting system shall be approved for pellet stoves by a certified
testing Laboratory. PL Vent must be used for venting all Freestanding stoves.
Do not use to vent pellet appliance these venting materials and products:
- Dryer vent
- Gas appliance (Type B) vent
- PVC (plastic) pipe
- Single wall stovepipe.
The pellet stove is not the same as other stoves. It has a forced draught of flue gas by a fan, which keeps the firebox in a vacuum
and the entire flueway slightly pressurize. For this reason the flue must be completely airtight and correctly installed to ensure both
trouble-free operation and user safety.
• The flueway must be made by specialized personnel or firms, as outlined below.
• Thefluemustbeinstalledinsuchawayastoguaranteethatperiodiccleaningcanbecarriedoutwithoutdismantlinganypartswhatsoever.
• Pipes should always be sealed with silicone (not cement-based sealants) or specially adapted gaskets/seals, which retain their strength
and elasticity at high temperatures(>450°F /230°C),and should be fixed with at least three sheet metal screws.
Using the relative pipe clips, fix the flue to the wall so that it does not weigh on the smoke fan.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
Do not connect to a flueway into which extractor hoods discharge vapours.
The very hot exhaust gases may cause skin burns: keep a considerable distance away from the appliance. The exhaust gases
from the combustion of pellets fuel may dirty the outside of the walls. To avoid such possibility terminate the vent
above the roofline.
Pipes and maximum usable lengths
The exhaust pipe on all stoves is 3" (76 mm) O.D. so the stove was designed to accommodate a 3" stove pipe adaptor but the diameters of the
pipes dependsonthe typeofinstallation.Your installation may require the use of 4" vent as shown in Table1.

TYPE OF INSTALLATION

Maximum length (with three 90° elbows)
For installations more than 4000' (1200 m) above sea level
Maximum number of elbows
Length of horizontal sections with minimum 3% gradient
Losses in pressure associated with a 90° elbow can be compared to those incurred by three feet of pipe. An inspectable union-tee
can be considered equivalent to a 90° bend.
EXAMPLE: if installing a section greater than 20' in length with 3" diameter pipe, calculate the maximum usable length in the following ways:
• If a maximum of three 90° elbows are used,the maximum length of the section will be 25'.
• If a maximum of two 90° elbows are used and bearing in mind that a 90° bend can be replaced by 3' of pipe,the maximum length of the section
will be 25'+3' = 28'.
• If a maximum of one 90° elbows is used and bearing in mind that a 90° bend can be replaced by one meter of pipe, the maximum length of the
sectionwillbe25'+3'+3'= 31'.
