Supporting Floor Systems
It is the ultimate responsibility of the installer to ensure that
proper concrete slab supports are used.
WARNING to the licensed design professional and/or
building contractor: It is your responsibility to be certain
that the Mason-Lite can be properly supported by the
combustible floor system on which the fireplace will rest.
Rebar locations
Lay-out the position of the fireplace and drill holes where
the rebar will be located. Secure the #3 rebar 4 inches into
the concrete foundation with ITW Epoxy or Simpson
Epoxy. Follow manufacturer’s instructions for installation of
rebar into slab.
Wood Floor
Anchorage of fireplace to wood floor construction is
required. Refer to Figure 4
for anchorage dimensions.
Four anchors are required to attach to the sub-flooring
framing.
Crawl Space or Upper Floor:
For installation of firebox over combustible crawl spaces
or upper floors, anchorage of the firebox is required.
Illustrations of examples of possible anchorage methods
are shown in Figures 1 thru 3 depending upon the type of
floor framing. Final method of anchorage is to be
determined by licensed design professional.
For conventional framing, where the floor joists are
parallel with the sides of the firebox, the addition of floor
joists to align with the anchor brackets allows the brackets
to be directly connected to the floor joists.
Note that additional floor joists may be required to
support the weight of the firebox and chimney. Where the
floor joists run parallel to the front of the firebox,
anchorage can be accomplished in like manner as shown
in Figure 1 using blocking between the floor joist.
For floors supported by I-Joists, the method of
anchorage is illustrated in Figures 2and 3. Figure 6
illustrates the general arrangement of anchorage to floor
framing.
It is important to take into consideration that the load for
the Mason-Lite Fireplace must be considered as additional
dead load that will have to be supported by the floor
framing. Additional floor joists or I-joists may be required
as determined by the licensed design professional.
It is the task and responsibility of the general
contractor/installer to see that the proper reinforcement for
weight loads are made by a licensed design professional
prior to the fireplace installation.
As stated above, it is desirable to place additional
framing for alignment of anchor rods. Refer to Figure 4 for
anchor rod locations.
Attach the firebox side wall anchors to steel support frame
by inserting all-thread rods through holes on the bottom
flange on the steel support frame as shown in Figure 7.
Secure with two Ø 2” o.d. x Ø 9/16” i.d. x 0.10” Washers
and two 1/2”-13 UNC Nuts.
