Section 4 – Installation of Door Frames & Facades
Temp-Cast 2000 Installation Manual

ARCHED FIRE DOORS - Step Four
When the facade is complete and the
masonry has fully set, remove the 2
temporary bolts from the frame. (If the 2
small brackets were used, this will detach
the frame from them.) The door frame is
now independent of the fireplace core and
will not be affected by the thermal
expansion of the core.
Replace the doors on the frame and check
for proper fit and operation.
ALTERNATE ATTACHMENT METHOD
If cutting or chipping masonry around the
bolts is not possible, an alternate (but more
difficult) attachment method can be used.
(See Fig. 15.)
Remove the 4 permanent bolts from the
door frame. Build the facade around the
door frame (or around the flange, as the case
may be) and complete the masonry work.
When the masonry work is fully set, (i.e.
after 1 or 2 days) make a mark on the
masonry where the 4 bolts will go, using the
bolt holes as a guide. Care must be taken
at this point so that the threaded holes on
the outside of the frame are not damaged.
Now unbolt the frame from the 2 temporary
brackets and take the door frame out. (If the
"coreflex" spacer comes out with the frame,
replace it before the frame is re-installed.)
Using a masonry drill of the same thickness
as the permanent bolts, drill holes into the
masonry at the marks made earlier. These
holes should be at least 1" (25mm) deep and
on a slight angle (about 5 degrees) towards
the firebox. (Fig. 15)
Re-install the door frame and attach with the
four permanent bolts - the slightly angled
holes will draw the frame tight to the
ceramic wool gasket. (Do not re-bolt the
frame to the temporary brackets.)
AIR SUPPLY DOORS
If an air supply door is to be installed, its
frame is installed in the facade when it
reaches the desired height. (See Fig. 1b).
The installer can use mortar, lead anchors or
"tap-con" screws to secure the door frame.
CLEAN-OUT DOORS
Similarly, clean-out (soot) door frames are
installed when the facade reaches the height
of the clean-out holes in the heat exchange
channels. The soot doors should be located
on both sides of the heater, at the bottom of
both heat exchange channels, in line with the
cross-manifold, Part # 3.
When a side chimney connection is made,
one of the two clean-out doors should be
placed at the bottom of the chimney, so that
the bottom of the heat exchange channel on
that side can also be accessed from the same
door. In the case of a rear chimney
connection, a third clean-out door will be
required for the chimney itself. (Standard
chimney clean-outs are available at brick
supply yards or a third Temp-Cast clean-out
can be ordered.) Cover all door frames
immediately after installation to keep them
clean.
