Assembly Instructions
1. Place the Mason-Lite appliance hearth base parts on top of
your non-combustible floor, metal base or CMU blocks. For
concrete slabs, supporting floor must be ASTM 90 rated.
2. a)
Combustible Floor Installations:
Position hearth
slabs on top of 6” CMU blocks or Metal Base (Figure 15).
All-thread rods should stick up through the holes on the
hearth slabs when installing metal base.
b)
Non-combustible Floor Installations:
Position Hearth
Slabs in desired location, check that overall width
measures according to table in Figure 15. Draw an outline
and mark rebar center locations. Remove slabs and drill
holes at rebar centers 4” deep into concrete slab. Secure
rebar with epoxy.

Anchor Bracket All-Thread Rods are secured to the
bottom flange
of the Metal Base with eight (8) flat washers (2”OD x 9/16”ID x
0.10”) and eight (8) 1/2-13 UNC Nuts.

of the Metal Base with eight

3. Mix a batch of mortar and prepare bottom surface of Right
Side Hearth to be bonded (
Figure 16
), then lower the piece
into place on the outline created before. Align lower Right
Side Hearth on the outline created. The width dimension
allows for an approximate gap of 1/8” between slabs for the
additional mortar to unite the remaining slabs. Continue
process for remaining hearth sections while moistening and
adding mortar between joints at slab ends.

4. Apply mortar in like manner to the Center Hearth and place
next to the Right Side Hearth. Check that surface is LEVEL
and use shims if necessary.
5. Apply mortar to the remaining Hearth except this time apply
beading on surface to be facing floor as shown in
Fig. 17
.

Before installing side walls, confirm placement of outside
combustion air access (if required), this can be installed
either side depending on which side is accessible to
outside combustion air (all diagrams in this manual show
the combustion air inlet hole on the right side). Prepare side
wall mating surfaces with the prepared mortar as shown in
Figure 18
.

Keep the assembly of the next sections of the firebox side
walls moving up, keeping components moist, mixing mortar
as you need it and threading the mortar appropriately as you
stack each section, one onto the next. Constantly check for
squareness and levelness while building each course of
block. As you complete each section, make certain that you
adhere the mortar at each and every joint.
