Power (Side-Wall) Venting-Important Note Regarding
cCAUTION: Crown Boiler Company will NOT assume responsibility for damage to, and
deterioration of, exterior building materials, e.g. brick, siding, clapboards, and etc., in close
proximity to the vent terminal due to operation of a power vented, oil furnace. This policy
is applicable regardless of the cause of sooting.
Two (2) problems typically arise when power venting any oil-fired appliance.
1) Soot buildup may occur at an accelerated rate on critical components of the
furnace oil burner, e.g. the primary control flame sensor ("cad cell"), the burner
head, oil nozzle, and etc.
2) Severe damage may occur to external surfaces of the structure in the event the
furnace continually produces a high level of smoke in the flue gases. Excess
smoke and soot can be produced for many reasons, some of which cannot be
successfully controlled by the installer and the appliance manufacturer.
NOTICE: Crown Boiler recommends the use of a chimney to vent our residential oil
furnaces. If a power venter must be used, it is the responsibility of the installer and power
venter manufacturer to design and assemble a satisfactory power vent system.
A. VENTING:
NOTE: On the CSHB60-90 it is possible to rotate the flue elbow (which is factory installed for vertical discharge)
90° counterclockwise from the vertical position to adapt to various venting systems.
c CAUTION MUST BE TAKEN NOT TO EXCEED 90° ROTATION (OF THE FLUE
ELBOW) COUNTERCLOCKWISE OR RIGHT FROM THE VERTICAL POSITION.
ROTATION OF FRONT FLUE ELBOW
When an installation requires that the flue exit out the left hand side casing on a front flue unit, remove screw
securing the 90 deg. elbow and rotate it 90° counterclockwise. Then, remove knock-out in side casing and extend
vent through the opening.
NOTE: ROTATION OF FLUE PIPE IS ONLY ALLOWED FOR LEFT HAND SIDE VENTING
APPLICATIONS.
The CSHB60-90 may be vented through a standard correctly sized chimney.
The CSHB60-90 may also be horizontally vented through a side wall. Crown has available the Field model FDVS-
45/FVOP-415 side wall vent kit for such applications. When installing the FDVS-45/FVOP-415 side wall vent kit,
outside combustion air must also be applied to the burner. The following table identifies application order
information.
