SECTION 5: AVOIDING INSTALLATION ERRORS
The Temp-Cast modular system was designed to be as "fool-proof" as possible and is easily and
properly installed when the instructions are followed. Unfortunately, every year, one or two installers do
not read or follow the instructions, resulting in a costly repair. This section reinforces the most
important installation points which cannot be ignored or altered
for a safe and effective heater.
Review this list before starting the installation and as the work progresses, especially if you are hiring
someone to do the installation. If both you and your installer follow this check-list, the likelihood of errors
is greatly reduced.)
1. ALL AIR-SPACES
BETWEEN THE MASONRY FACING AND THE CORRUGATED SPACER
MUST BE BACK-FILLED WITH MORTAR. (Air spaces between facing and corrugated spacer will
restrict the heating output of your unit to as little as 20% of its design capability. This is a very
costly error to fix – the entire facing must be removed and correctly re-installed.)
2. DO NOT USE CONCRETE BLOCKS AS A FACADE. (Concrete blocks are difficult to properly
back-fill behind without air spaces, especially if they are cut for fitting. We suggest only a brick,
natural stone or natural rock facing with a minimum 4” thickness but not more than 6”.)
3. A MASONRY FACADE MUST
BE INSTALLED ON ALL 4 SIDES AND TOP OF THE HEATER,
EVEN IF SOME AREAS WILL NOT BE VISIBLE. (Failure to have a continuous masonry
façade of at least 4” thickness on all 4 sides and top of the heater will create a fire hazard,
which could cause property damage, personal injury or death!!)
4. ENSURE THE CORRUGATED SPACER IS ATTACHED TO ALL 4 SIDES
OF THE CORE
BEFORE STARTING THE FACING. )
5. THE SPACE BETWEEN THE BACK OF THE DOOR FRAME AND HEATER CORE MUST BE
SEALED WITH CERAMIC WOOL. (This will prevent any combustion gases from leaking out
around the door frame.
6. DURING TRIAL FITTING, ENSURE THAT THE AIR SLOT IN THE BOTTOM OF THE DOOR
FRAME IS ALIGNED WITH THE AIR SLOT IN THE CONCRETE PAD. (This is the reason the
frame cannot be mounted on the outside of the masonry work when the facade is thicker than 4" -
the air slot will not line up properly. If you purchased the Temp-Cast “square” door system, a
special air-deflector will be included.)
7. THE AIR SLOT BETWEEN THE BOTTOM OF THE DOOR FRAME AND THE CONCRETE PAD
MUST NOT BE OBSTRUCTED. (The facing under the door frame must be “cut” to create a 2” x 15”
air slot & this space must be kept free of rough masonry, mortar, ceramic wool or other debris.)
8. PROVIDE ADDITIONAL COMBUSTION AIR AND A NON-COMBUSTIBLE HEARTH FOR BOTH
DOORS OF A "SEE-THROUGH" FIREPLACE. (8” dia. of air needed, divided between the 2 doors.
This creates an air-wash for each glass door. See Fig. 16.)
9. PROVIDE AN EXPANSION JOINT ON TOP, BETWEEN MASONRY CAP AND MASONRY
FACADE. (To prevent cracks caused by vertical expansion of the core.)
