DM 54 Chimney System: Installation Instructions
30
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 49 & 50).
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 49).
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
STANDARD firebox smoke dome assembly and for the
DM 54 chimney to run straight up the back side of the bearing
header (Figure 50).
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
STANDARD smoke dome lid with the outer casing block cen
-
tered 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 48) 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 staggered horizontal joints between the inner liner
and the outer casing block.
Note:
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.
Both the inner casing block and the inner liner compo-
nents have tongue and groove type detailing on each end to
assure alignment and interlocking of the pieces as they are
stacked and glued together.
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.
