Framing and Finishing
Check appliance to make sure it is levelled
and properly positioned.
The appliance should only be mounted on the following
surfaces:
•
A flat combustible (burnable) surface.
•
A raised wooden platform.
•
A concrete block or other solid object placed
beneath each of the four corners of the appliance.
To mount the appliance:
1. Choose unit location.
2. Four (4) nailing flanges are supplied with the fire-
place (found on the fireplace hearth). To level the

flanges from the hearth and install at the sides of the
fireplace as shown in Figure 4.
Finishing
CAUTION: All joints between the finished
wall and the appliance surround (top and
sides) may be sealed only with non-com-
bustible material. Only noncombustible
material can be applied as facing to the ap-
pliance surround (the black painted face).
Finish the wall with the material of your choice. Refer to

ing a combustible mantel or other combustible projec-

Moisture Resistance
This outdoor fireplace will shed moderate amounts of
water, but is not waterproof. Water and condensing wa-
ter vapor may enter the chase under certain conditions.
The fireplace will not perform as an exterior wall. Mois-
ture penetration must be considered for construction
that places the fireplace in structure walls or on mois-
ture sensitive surfaces.
When installed on exterior walls: MHSC recommends
the fireplace chase be constructed outside the struc-
ture's weather envelope. Where the platform meets
the wall, use a flashing detail similar to that required
for attached decks. Chase platforms, including hearths
should slope away from the structure at 1/4 in per foot.
The fireplace can be shimmed level.
When installed on surfaces where water may collect or
cause damage: MHSC recommends a slope of 1/8 in
to 1/4 in per foot towards the drain port suggested. The
fireplace can be shimmed level.
Hearths should slope away from the front of the fire-
place and chase at 1/8 in to 1/4 in per foot. Metal safety
strips must be on top of any combustible hearth materi-
als used for moisture management.
