Installation
Barometric Draft Control
Proper draft must be provided for your
ENERGY KING Wood/Coal Boiler. Draft is the
force that moves air from the boiler up through
the chimney. Draft is measured in inches of
water column.
The amount of draft in your chimney depends
on the length of the chimney, local geography,
nearby obstructions and other factors. Too
much draft may cause the fire to burn too fast,
while inadequate draft may cause smoke to
back up into the ENERGY KING heating
appliance, creating a possible hazard.
A barometric draft control must be installed into
the chimney connector. Please refer to
Figure
8: Venting Requirements
and
Figure 10:
Barometric Draft Control.
Barometric draft controllers limit the draft (the
suction pulling air into the solid-fuel heating
appliance burn chamber). A pivoted,
counterbalanced flap is pulled open by the draft
when the draft reaches a critical amount. This
permits air to enter the chimney, thus
preventing the draft in the heating appliance
from rising any higher.
After installation of the ENERGY KING
Wood/Coal Boiler is complete and a fire has
been built, the chimney draft should be
established and maintained from .04
″ to .06 ″
water column of draft. If this setting is
exceeded, it could cause a solid fuel fire to
burn out of control.
Risk of Fire: Do not operate with the flue draft
exceeding .06
″ (14.95 Pa) water column.
Figure 10: Barometric Draft Control
Moderate draft in
the chimney will
pull the
barometric draft
control open just
enough to
maintain the
appropriate draft
for your heating
appliance.
Excessive draft in
the chimney will
pull the
barometric draft
control further
open, allowing
more air into the
chimney and
reducing the draft.
With no draft in the
chimney, the barometric
draft control remains
closed, allowing no air
to enter.
