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 5 using
blocking between the floor joist.
For floors supported by I-Joists, the method of anchorage is
illustrated in Figures 6 and 7. Figure 10 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.
The dead weights for the fireplace are noted in Table I. 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 10 for anchor rod
locations.
