DM Chimney Installation - Straight Run
Where the chimney run is to be straight run the DM chimney by setting
a DM outer liner in a bed of Earthcore Adhesive on top of the MAGNUM
top plate where the outer liner is centered from side-to-side and flush
with the back of the top plate. Be sure that the outer liner aligns with the
flue hole in the top plate. Set in this way the DM outer liner will sit three
and three-fourths inches (33/4”) back from the front face of the top plate.
This total set-back distance makes it possible for a three and one-half-
inch (3½”) thick bearing header to pass over the MAGNUM firebox
smoke dome assembly and for the DM chimney to run straight up the
back side of the bearing header
(Figure 31)
.
Next, set the DM chimney inner liner’s six-inch (6”) tall "starter" piece
inside the first outer liner. The six-inch (6”) tall inner liner has a female
end and a flat end. Set this inner liner with the flat end down. Be sure
that the starter piece is set into the Earthcore Adhesive so it is fully
sealed to the top plate.
IMPORTANT:
Earthcore Adhesive all outer liners together, and Earthcore
Adhesive all inner liners together. Do not Earthcore Adhesive the air
space between the liners and the outer casing blocks.
For every 12' of DM54 Flue, you should order a bucket of Earthcore
Adhesive MP50.
Starting with the six-inch (6”) tall inner liner starter piece, create six-inch
(6”) staggered horizontal joints between the inner liner and the outer
liner as the chimney is built up.
Both the outer liner and the inner liner components have tongue and
groove type detailing on each end to assure alignment and interlock of
the pieces as they are stacked and glued together.
NOTE:
If the six-inch (6") inner liner starter piece is broken or otherwise
unavailable, then a full twelve-inch (12”) tall inner liner piece can be cut
to six inches (6”) in height to make an inner liner starter piece.
After setting the DM inner liner starter piece, apply Earthcore Adhesive
to the top of the starter liner. Continue the straight chimney run by
placing a full height inner liner onto the six-inch (6”) starter liner. The top
of this full height inner liner will sit 6” above the top of the outer casing
block that was previously set.
This six-inch (6”) offset between joints of the inner liner stack and the
joints of the outer casing stack continues to the top of the chimney run.
Continue the straight vertical DM chimney by setting an outer liner
onto the Earthcore Adhesive top surface of the preceding outer liner.
The grooves on the bottom end of the upper outer liner fit onto the
tongues on the top of the lower outer casing block. This assures proper
alignment of the two components.
Next, place a full height inner liner onto the Earthcore Adhesive top end
of the previously set inner liner. Proceed this alternate stacking of outer
liner and inner liners until the desired height of the flue is attained.
