Firestop Radiation Shields also provide complete separation
from one floor space to another or attic space as required
by most codes. When the double wall pipe passes through
a framed opening into an attic space, the Firestop must be
placed into an attic floor as shown in

Firebrick Installation Instructions
Firebrick (sold separately) are required to complete
your Burntech® Fireplace Installation. Failure to
install firebrick
may cause immediate hazard, property
damage or loss of life and will void all liabilities to the
manufacturer and will void all warranties explicit or
implied.
Firebrick Options
Burntech® MODULAR FIREBOX KITS are available in
Herringbone and Running Bond Patterns (see figures 61
and 62) as well as color options. Refer to your Product list
at the back of your manual for proper sizing and patterns.
S
TANDARD MASONRY FIREBRICK may also be used
instead of Burntech® MODULAR FIREBOX KITS. Please
•
•
consult with your local masonry supply yard for approved
firebrick.
Firebrick thickness must be a minimum of 1 1/8” thick
and shall only be applied with Burntech® Mortar. Do not
leave any voids or gaps behind the firebrick or doing so
may result in the brick falling off when exposed to high
temperatures.
To ensure a good bond between the firebrick and the
Burntech® FIREPLACE, use a damp sponge to moisten
the firebrick and the Burntech® FIREPLACE prior to
installation of brick. Some installers have found it be
beneficial to place a 1/16”-1/8” skim coat of Burntech®
Mortar over the inside of the Burntech® FIREPLACE
firebox area prior to installation of brick as well as parge
coat the Firebrick before it is laid to ensure a strong bond
between the Modular components and the Firebrick.
Burntech® Mortar shall be used as the adhesive and as the
grout between the firebrick. The grout joints between the
firebrick shall be no more than 3/16” wide.
It is recommended that you use a licensed Masonry
Contractor to lay the brick to ensure a quality finish.
Your contractor may need to drill for gas, electrical or
combustion air kit access holes. Be sure to patch around
these holes with Burntech® mortar.
Make sure the fireplace is installed with the finished firebrick
floor of the fireplace so that it is
at least 11” (eleven inches)
above the combustible floor system.
Disclaimer: Burntech® Fireplace Solutions wishes to
express that as the manufacturer of Burntech® Fireplaces,
they cannot take any liability or responsibility for the way the
firebrick or the firebrick mortar performs. It is not unusual in
the course of the life of the firebrick, or the firebrick mortar, for
heat stress cracks to appear. Burntech® Fireplace Solutions
cannot be responsible for this and other wear and tear to the
firebrick and mortar.
Modular Firebrick Lining
If using our Burntech® Firebrick Liners, simply use an extra
bag of the mortar we supply. Install Hearth Liner first, rear next
and sides last. Consider if brackets for grates will be required
also if pre-drilling is required for gaslines, electrical or if the
outside combustion air kit is to be installed.
The rear Liner
Panel is straight from the bottom to the top front edge of the
Downdraft Diverter edge. The space behind does not have to
be filled (
Figure 60
).
Area behind
Rear Firebrick
Liner Panel can
remain empty
