The Temp-Cast kit system consists of a high-temperature concrete (i.e. "refractory") core, assembled on your site from interlocking modules. This simplifies the assembly of the heater, so that specialized "heater-masons" are unnecessary. In fact, masonry skills are not needed to assemble the Temp-Cast core kit. A large number of our heaters are completed by masons and competent DIYers who have never seen one before, with the guidance of our detailed planning and installation material.

The modules in the Temp-Cast 2000 wood-fired heater are engineered for the most accurate fit possible. High quality aluminum molds and strict quality control measures produce parts with dimensions within narrow limits. The core parts have a unique male/female interlocking key system which makes the assembly smooth and fool-proof. A thin refractory cement is used between the parts.
The custom refractory mix produces a product with excellent serviceability at high temperatures, maximum heat retention and high thermal conductivity.
The following are some sample sections from the Wood Installation Manual:
Assemble the second course, parts #7, #8 & #9, using refractory mortar. Note that the parts are numbered in the order that they should be placed. (For a Temp-Cast "See-Through" fireplace, these 3 parts are slightly different, as in the accompanying illustration.)
Use the rubber mallet to seat the modules. Remove excess mortar and wipe inside and out with a damp sponge as work progresses.
NOTE: When installing the modules on this course and subsequent courses around the firebox opening, take care that the parts are flush at the front of the fireplace. This will produce the most level surface on which to install the door frame later.
Continue the smoke throat course with parts 19 & 20. (Note that the slightly beveled surfaces of these modules face in towards the firebox.)
Step 11 Thru 16: (Back Oven Installation)
Assemble the Bake Oven parts, in numerical order. Parts 22B and 23B are laid in a full bed of refractory mortar and seated with the rubber mallet. Use refractory mortar wherever one part joins another.
Step 18 Thru 20: (Corner Fireplace)
If the chimney connection is to be made in the side of the fireplace, dry assemble the first corner channel and mark the location of the flue hole on the designated surface. Mark a location for a clean-out (soot) door on the opposite channel. Cut these holes outside.
Re-assemble the first two corner channels, using a little refractory on their bottom edges. Use a temporary support around each pair of channels - wire, rope or "bungee" cord, so they do not fall during the next few steps. (They will be removed and replaced at Step 24 to apply the corrugated spacer.)
Continue with the other four corner channels, using refractory mortar between them. Wire or tie each pair as they are installed.
