Burntech® Firebrick Liner
The firebrick lining is not supplied as part of your Burntech®
fireplace but can be purchased from Burntech®. They are
available in split herringbone and full running bond patterns.
(see
Figures 24
and
25
)
You also have the option to have custom firebrick installed,
but it must be at least 1-1/8” thick.
Before you install the lining, you will need to drill all the
required gas and electrical line feeds and the combustion air
supply access holes.
Disclaimer:
Burntech®
cannot be held liable for the way
firebrick or firebrick mortar performs. It is not unusual for heat
stress cracks to appear on the firebrick or firebrick mortar
during the life of the fireplace.

Fireplace Finishes & Combustible Trim Clearances
Mantel and Mantel Shelf Clearances – As with any radiant
heat fireplaces, all Burntech® Fireplaces must comply with
building code safety clearances, per units that have
openings of 6 sq. ft. (six square feet) or greater.
You must
keep combustibles such as trim 8” away from the firebox
opening (for mantel clearances, see
Figure 26
).

Mantel and side clearances
Attention:
The manufacturer suggests that when building
out a fireplace, that the owner and installer opt for complete
safety. Burntech®, therefore, advises that combustible
mantel shelves feature clearances that are more than the
12” (twelve inch) minimum equal to the projection of the
shelf. As a guide, figure that a 10” (ten inch) wide shelf
should be 20” (twenty inches) above the fireplace opening.
Walls That Adjoin – Safety codes and all practical outlooks
insist that your fireplace cannot be installed closer than 2 ft.
(two feet) to any walls in the room the fireplace is housed in
or to any walls of adjoining rooms.
