Chimney Set-up
Since you have already preplanned the chimney run, you
should know exactly how the installation is to be accom-
plished - how much pipe is required, the number of elbows,
if any, and type of termination to be used.
CAUTION:
REPORT TO YOUR DEALER ANY PARTS
DAMAGED IN SHIPMENT, SPECIFICALLY CHECK THE
END CONNECTION OF CHIMNEY SECTIONS AND
ELBOWS.
NOTe:
The WMC36 may use Vermont Castings Group
model SK8, or Model S (three wall) chimney systems.
However, a TWABR adapter collar is required when using
the Model S (triple wall) chimney system on this unit. The
WMC42 is designed to use only the "S" triple wall chimney
system. Either chimney system may be used, but
must
not
be mixed.
NOTe:
To use the TWABR adapter on the WMC36, remove
and discard the cover plate on the top shield. (Fig.
8)
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace in final
position and measure out from the wall: 9
Z\v
" (235 mm).
Mark a spot on the ceiling directly above the fireplace.
Draw a line parallel to the back wall through this mark.
(Fig. 11)
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 11)
Offset Installation
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by us-
ing Vermont Castings Group elbows. Use the
30° Offset
Elbow
table on Page 5 to determine proper offset and
parts required.
Each offset requires two (2) elbows. The second elbow
is equipped with support straps. It is very important to
install the second elbow in each offset as close to the
ceiling or support as possible so the elbow straps can be
secured to framing members to help support the weight
of the chimney.
Determine offset distance of your chimney arrangement
from centerline of fireplace to centerline of chimney where
it is to pass through ceiling.
Locate center point of the chimney on ceiling as though a
straight up chimney arrangement is to be used. Measure
your offset dimension from straight up chimney center
point on ceiling.
Ceiling Chimney Hole/
Possible Obstructions
The size of the hole in ceiling will vary with the angle at
which the chimney passes through ceiling.
Drive a nail up through ceiling at marked chimney center
point. Go to floor above and see where hole will be cut.
Check to see where existing ceiling joists and other pos-
sible obstructions are located...i.e. wiring, plumbing etc...
If necessary, reposition chimney and/or fireplace to avoid
obstructions.
Cutting the Hole
Cover fireplace collar opening and cut proper sized chim-
ney hole in chimney. The SK8 pipe allows you to run pipe
through a typical 16” on center joist without cutting joists.
