at least 1/” to provide a positive joint. The safety strips
must also extend at least 1

sides of the fireplace. (Fig. 13)
NoTe:
Safety strips are not required over noncombus-
tible floors where all supports at the base of the fire-
place are noncombustible.
Nailing Flanges
1. This unit is shipped with four (4) nailing flanges pre-
mounted on either side of the fireplace to accommo-
date two () different drywall thicknesses. The 1/”
drywall flanges are shown in Figure 13 while the top
and bottom flanges are for 5/8” drywall.
. Bend the desired flanges out 90° on both sides of
the fireplace. Slide the fireplace into the framed
opening until the flanges contact the front surfaces
of the framing. Level the unit and secure firmly in
place.
waRNiNg:
Risk of fire may occur if a 1/” minimum
spacing is not maintained between the fireplace and
framing members.

Internal Outside Air Cover Plate
(Shown in the closed position for
use with AKMST)
installing outside air kit
An outside air kit may be installed on the Stratton. The
AK-MST allows for 100% of required combustion air to
come from a source outside of the house. If desired, or
if local codes mandate the use of an air kit, then an AK-
MST is required to complete the installation (from air kit
to the outdoors). If the outside air kit is to be used, the
AK-MST MUST be installed BEFORE the fireplace is
enclosed.
also, the internal outside air cover plate
must be closed by moving to the up position as
shown in Figure 14. This will prevent cold air from
entering the home.
NoTe:
Four (4) inch Class 1 air duct, material or metal
duct (not supplied) may be used with AK-MST.
(For
installation in New york State, only aluminum, non-
combustible flexible or type “o” metal ducting is
permitted.)
installation precautions
The duct termination should be located so it is exposed
to an out-of-doors opening of at least 100 square inch-
es. If the duct termination must be located in a crawl
space or basement, be sure the termination area has
100 square inches of ventilation opening to outside air.
The duct termination must be located so it does not
compete for air flow with exhaust fans, gas vent hoods
or other air consuming devices or appliances. It must
not be blocked by rafters, insulation materials or other
obstructions. The less restrictive the air supply, the bet-
ter the AK-MST will perform.
It is a good practice to protect your hands and eyes
during installation by wearing work gloves and safety
glasses.
caUTioN: Do not install the air kit termination into
a garage or other area that could contain flammable
liquids or fumes, or into an attic space.
installation instructions
Determine the location of the fireplace as described
in the fireplace Installation Manual. Then plan location
of the duct termination and the route of the duct run
between the fireplace and the duct termination.
The duct run must be limited to a maximum distance
of 40 feet (1 m) from the fireplace pipe collar to duct
termination. This will provide the least restriction to air
flow. No more than four (4) 90° elbows may be used.
