DM 54 Chimney System: Installation Instructions
44
DM 54 Chimney Alignment:
Where the chimney run is to be a straight vertical run
the DM 54 outer casing block sits directly onto the Isokern
smoke dome lid. The DM 54 outer casing block, properly set
is intended to be flush with the back face of the firebox smoke
dome assembly (Figures 89 and 90 ).
Set in this way the DM 54 outer casing block will sit
three and three fourths inches (3-3/4”) back from the front face
of the smoke dome. (Figure 89).
This total set-back distance makes it possible for a
three and one-half inches (3-1/2”) thick bearing header to pass
over the MAGNUM firebox smoke dome assembly and for the
DM 54 chimney to run straight up the back side of the bearing
header (Figure 91).
Installation of the DM 54 chimney:
Begin straight DM 54 chimney runs by setting a DM
54 outer casing block in a bed of mortar on top of the MAGNUM
smoke dome lid with the outer casing block centered on the lid
from side to side and flush with the back of the smoke dome
lid.
Be sure that the outer casing block aligns with the flue
hole in the smoke dome lid.
Next set the DM 54 inner liner’s six inch (6”) tall
starter piece (Figure 89) inside the first outer casing block. The
“factory” version of the six inch (6”) tall inner liner starter
piece has a female end and a flat end. Set this inner liner starter
with the flat end down.
Set the downward end into Earthcore Mortar so that it
is fully sealed to the smoke dome lid.
WARNING:
Do not mortar the air space between the liners
and the outer casing blocks.
Starting with the six inch (6”) tall inner liner starter
piece creates six inch (6”) staggered horizontal joints between
the inner liner and the outer casing block.
Both the outer casing block 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.
Notes:
If the “factory” 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.
DM 54 chimney inner liners can be stacked with
either the male or the female end up. In either case start the
inner liner stack with a six inch (6”) starter piece.
