Installation

8Ussc
When Installing your heater in a window
• Select a window of adequate size and with the ap-
propriate clearances needed for a safe installation.
The mounting hardware supplied is designed for the
appliance to be installed in the approximate center
of the window. You will need to provide the attach-
ing hardware, (i.e. screws, wall anchors, etc.) of which
should be suitable for mounting to the outside surface
of your home or structure. You may choose to utilize
the supplied mounting system or a conguration of your
own. However, U.S. Stove shall not be liable for faulty
mounting congurations.
• Depending on your application, a solid resting surface
will need to be established on the window sill. If your
selected window’s bottom ange rises above the sill, a
board will need to be placed and should be level with
or just rise above that ange. Use the illustration to the
right for reference.
• The supplied support brackets will need to be mounted
before inserting the heater into the window. These
pieces will mount to the outside of the home or structure.
• Assemble the two Knee Braces to the Retention Bracket
using a washer (d) and nut (e) for each side. Tighten the
nuts then back them off to allow the bracket to slide
back and forth along the knee braces.
• Using a carpenter’s level or a straight edge, determine
the height of the retention bracket in relation to the
resting surface of the heater. Once you’ve determined
that mark, locate the mounting assembly 1/4” lower to
allow for precipitation runoff.
• Attach the Knee Braces to the home or structure using
the hardware that you have determined suitable for
your application.
• Once you’ve stabilized the Knee Braces, you’re ready
to insert the heater into the window/opening. Slide the
heater thru the window or opening. Insert item “a” in the
center hole of the bottom but don’t tighten fully. Allow
item “a” to engage the SLOT in the retention bracket
as shown in the illustration to the right. Slide the heater
into the window opening until it stops. The heater should
either stop on the window sash at the back of the hop-
per lid or on the window sill when it reaches the fan
enclosure, whichever comes rst.
• Align the holes in the retention bracket and heater bot-
tom. Insert a washer (b) and bolt (c), and tighten.
• Tighten the two nuts (e) on the knee braces.
• Using the window sill brackets, mount them to the side
of the heater, using the existing cabinet screws, then to
the top of the window sill with the screws provided. See
illustration on the following page.
• Lower the sash onto the top of the heater and proceed
to install the window insulation/ller panels.

Installing the ller panels
• Begin by assembling the left and right side ller panels together.
Slide part A into part B; Notice the range of adjustment. If the
openings on each side of the heater exceeds this range, you will
have to ll the gap by other means necessary to keep the window/
opening weather tight. Otherwise, proceed.
• Place the panel assembly against the bottom of the window sash
and bottom of the window frame. Slide apart the two sections
until the ange on part A meets the inside of the window frame
and the ange on part B meets the side of the heater. Using a drill
with a 5/16” socket bit, drive the self-tapping screw through the
hole in part A into part B. This sets the width of the panels.
• Peel away the protective coating from the two-sided tape on the
anges and adhere it to the window and framing.
• Measure the ller panel width and cut the foam insulation to size.
Peel away the coating on the tape strips and apply the foam to
the panels.
• Finish the install by sealing around the outside of the heater and
ller panels with a weatherproong silicone sealant.

When Installing your heater in an exterior wall
• Select a wall to the exterior of the building. This wall should
have the required clearance to combustibles inside and out
mentioned earlier in this manual. Make certain that electrical
wires, conduit, water or gas pipes do not pass through the area
you have selected
• USSC suggest the following installation illustrated to the right,
however, you may frame the hole cut out to your discretion.
A sturdy base for the heater to rest should be established.
• At the desired height, mark the hole location for your heater.
Measure and cut the appropriate size hole for your installation.
The cut out should border a wall stud. The next wall stud will
need to be cut.
Build a frame of 2 x 4’s at the dimensions suggested and secure
it in place by attaching it to the available studs.
• Before installing the heater, install the Knee/Support Braces.
• Install the knee/support braces supplied. See the previous page for installation. You may use the hardware
supplied or purchase the appropriate fasteners from your local hardware store for the type of material you
are securing into.
• Seal around the heater with silicone or caulking to protect against the weather.
