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

STEP FOUR
The facing material can now be applied, up
to the bottom of the door. The façade
should be planned so that the firebox
opening will be approx. 1” bigger than the
inner flange of the door frame – creating an
opening of approx 18 ½” high and 20 ¾”
wide. (This ½ “ space will eventually be
filled with ceramic fibre to create an
expansion & smoke gasket.)
(Note: follow the guidelines for installing
the facing material, as described in the
section "INSTALLING THE FACADE")
In addition, a ¼” steel angle iron must be
used as a lintel to support the masonry over
the door. Note the placement of ceramic
fibre around the doorframe and the steel
lintel, in order to create expansion gaskets.
The ends of the angle iron must also be
wrapped with ceramic fibre, so that
horizontal expansion of the angle iron will
not affect the facing material adjacent to
the ends of the lintel.
STEP FIVE
Lay a strip of ceramic fibre on top of the last
course below the door opening & position
the door in the opening, resting on the
ceramic fibre.
The door is attached to the facing
material (never to the core
), using the
brackets provided. When using brick or
block facing, the attachment bolts can be
laid in a mortar joint, or the back of the
brick or block can be cut & re-filled if a
mortar joint is not convenient. (The
bracket has a slot for the bolts, so in most
cases it can be moved to line up with a
joint.) When using other materials, which
cannot be easily cut or chipped (such as
river rock), then joints will have to be
more carefully planned to line up with the
slots in the brackets. (Alternately,
another hole could be drilled in the frame
to move the bracket in line with the rock
joints.)
When the facing material is complete,
loosely pack some ceramic fibre between the
doorframe and the facing on the remaining 2
sides and the top, to act as an expansion
gasket and smoke break. (It should be
slightly compressed, but do not pack the
ceramic fibre tightly into this opening,
which will prevent the gasket from
compressing as the door heats up. A small
amount of refractory mortar can be used to
hold the gasket in place, applied to the
firebox side of the gasket.)
SEE-THRU DOORS
The installation of a second square door will
be required with the See-thru option. It
should be installed in the same manner as
the first door, except that the rear door will
be about 1.5” higher than the front door. In
addition, the rear air deflector will rest on
Part #7ST, but will positioned in a similar
manner as the front deflector, in relationship
to the doorframe and the air slot from below.
(i.e. It must also direct air onto the bottom of
the door glass and into the firebox.) (See
Fig 16).
