Installation:
Step 1: Set the EPA Phase 2 qualified Standard Series fireplace
base plate in a full bed of Earthcore Mortar flat on a proper
concrete support foundation. Do not set the base plate so that it is
in span. Level the base plate by floating it in a bed of Earthcore
Mortar to full bearing against the underlying noncombustible
support surface.
Note: The bottom of the sidewall has a slightly smaller opening
than does the top (meaning when the sidewalls are made – the
board side of the sidewall has about a 1/8” narrower opening than
does the top. If the fireplace is stacked where the top sidewall is
placed upside down the clip will have a slight interference when
attempting to install. If this occurs, scrape away an area about
1.5” wide by the 1/8”.
Note: If the design preference is for a “flush hearth” (fireplace
floor flush with the room’s floor), the base plate can be omitted
from the assembly and the firebox walls built directly on the
concrete support slab. The fire brick floor of the firebox is then
set directly to the concrete support slab. This makes the fireplace
finished fire brick floor approximately one and one-half inches
(1-1/2”) above the top of the concrete support slab.
If the design preference is for a raised hearth (floor of
the fireplace elevated above the room’s floor), then the base plate
can be set on a noncombustible platform that is built up to the
desired raised hearth height on the concrete support slab.
When calculating raised hearth height be sure to allow
for the three inch (3”) thick base plate plus the one and one
half inch (1-1/2”) thick fire brick floor in addition to the height
of the platform. Whether a flush hearth is preferred or a raised
hearth, the combustible floor on front of the fireplace must be
covered with a noncombustible hearth extension set tight against
the fireplace front and extending at least 20 inches out from the
finished fireplace and at least 12 inches beyond the finished sides
of the fireplace opening.
For all “raised hearth” construction where concrete
blocks are used to create the raised platform, it is necessary to
use the base plate. Be sure to mortar the concrete block platform
together. CMU used for base plate support should be rated ASTM
90.
Note:
At all component placement, be sure to mortar all compo
-
nent contact surfaces with Earthcore Mortar. Check for complete
sealing of each contact joint while assembly progresses.
