Prerequisites for installing a pellet boiler
11
3. Negative pressure of the chimney
The boiler must be connected to a chimney or a vertical venting system that is capable of handling and producing a
negative breeching pressure of –0.020 “WC (-5Pa). Use a draft gauge to verify the indicated draft value, adjust
barometric damper as required. Drill a small hole in the connection pipe at about 2” from the boiler flue outlet
and use this hole as your measuring point.
Chimney draft
The suction effect of the chimney draft must extend as far as the pellet boiler. The maximum
flow rate that can be drawn through the chimney limits the maximum performance of the
pellet boiler. The boiler performance must be reduced if the chimney does not possess the
necessary cross-section. This may only be performend by authorised personnel.
Too strong a chimney draft increases heat loss while
idling and reduces the efficiency of the heating system.
We recommend installing a chimney draft regulator
(barometric damper). Chimney draft regulators are installed
directly into the flue gas tube or chimney.
Your state and local regulations must be observed.
4. Power venter
AutoPellet boilers are approved by the manufacturer for installation with the Field Controls
SWGAF power venter which is approved for wood pellet burning appliances.
Boiler installed with SWGAF power venters must follow all manufacturer´s installations and
must comply with all applicable codes from agencies having authority over the installation.
5. Cleaning
Clean the flue gas tube and chimney regularly.
Risk of chimney fire
Creosote-formation and need for removal:Low gas flue
temperature can cause creosote. The creosote condense
in the relatively cool chimney. As a result, creosote residue
accumulates on the flue lining. When ingnited, this creosote
makes a 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 accumulated it should be removed
to reduce the risk of a chimney fire.
Oxidation of chimney
Do not use metal brushes to clean chimneys made of
stainless steel.
Your state and local regulations must be observed.
