The FireRock fireplace must be erected on a
noncombustible base with a noncombustible 20” hearth
extension in front of the firebox opening and at least 8” on
either side of the firebox opening (Figure 2.1 on page 12).
There are 2 types of foundations that can be used in this
type of installation.
1. Concrete Slab (Figure 3.1)
2. Concrete Pad Supported by Masonry (CMU)
Tower (Figure 3.2) : Typically used when the
fireplace is placed over a deck. The noncombustible
pad is best made from a 6” thick concrete slab with
#4 rebar tied together at maximum 12” intervals,
center poured on top of corrugated metal. Concrete
pad must be supported by a full masonry tower
with no combustible underpinnings to withstand
the weight of the firebox and flue system.
NOTE
: Use of the FireRock base plate is optional for either
of the above foundation types (concrete slab or concrete
pad)

This fireplace is not designed to sit directly on or abut a combustible surface. Installing this fireplace directly on a
combustible surface may result in a fire or explosion, causing property damage, personal injury, or loss of life.
Foundations and footings must meet local code and
be approved by the local building authority. For any
foundation design and load requirements, check
with a structural engineer. Failure to ensure adequate
foundations can cause significant property damage.
It is the responsibility of the general contractor to
ensure adequate foundations.
