Flue gas system
2. Flue gas temperature
The flue gas temperatures are approximately the same for all AutoPellet Air covered in this manual.
The dewpoint of flue gas with wood pellets (max. 10% water content) is approx. 120°F.
It is possible to increase the flue gas temperature to prevent condensation inside the chimney and avoid
damage due to damp. Only authorised installers may increase the flue gas temperature.
Note:
The increase in flue gas temperature results in reduced efficiency and thus increases fuel
consumption.
3. Negative pressure of the chimney
The Furnace must be connected to a chimney or a vertical venting system that is capable of handling and
producing a negative breeching pressure of –0.4 “WC. Use a draft gauge to verify the indicated draft va-
lue, adjust barometric damper as required. Drill a small hole in the connection pipe at about 2in/ 50mm
from the Furnace flue outlet and use this hole as your measuring point.
Chimney draft
The suction effect of the chimney draft must extend all the way to the Furnace flue pipe connection. The
maximum flow rate that can be drawn through the chimney limits the maximum performance of the chim-
ney connection. The Furnace performance must be reduced if the chimney does not possess the necessa-
ry cross-section. This may only be performend by authorised personnel.
4. Power venter
AutoPellet Air are approved by the manufacturer for installation with the Field Con-
trols SWGAF power venter which is approved for wood pellet burning appliances.
Furnaces installed with SWGAF power venters must follow all manufacturer´s instal-
lations and must comply with all applicable codes from agencies having authority
over the installation.
5. Cleaning
Clean the flue gas tube and chimney regularly. Solid fuel burning appliances need to be cleaned frequent-
ly because soot, creosote, and ash may accumulate. The hotter the fire, the less creosote is deposited.
Cleaning intervals can vary in warm periods due to this and become more frequent.

Creosote-formation and need for removal:Low flue gas
temperature can cause creosote. Creosote can conden-
se in a relatively cool chimney. As a result, creosote resi-
due accumulates on the flue lining. If ignited, this
creosote will create an extremely hot fire. The chimney
and the chimney connector should be inspected at least
twice monthly during the heating season to determine if
a creosote buildup has occurred. If creosote has accu-
mulated it should be removed to reduce the risk of a
chimney fire.

Do not use metal brushes to clean chimneys made of
stainless steel.
Your state and local regulations must be observed.
