rated for at least 500ºF, 260ºC, is suitable) or adhesion problems may result. Apply the
adhesive inside the door groove (gasket channel) and install the new gasket with a gentle
pressure. Let dry for at least 24 hours. To replace the glass gasket, simply remove the glass
retainers holding the glass to the door frame. Remove the glass and peel off the gasket
surrounding it. Replace it by a new, self-adhesive glass gasket. The proper replacement
gaskets are available from your Osburn dealer in the following dimensions:

FIREPLACE INSTALLATION
3.4.1 Locating the OSBURN STRATFORD
A. The best location to install your fireplace is determined by considering the location of
windows, doors, and the traffic flow in the room where the fireplace is located, allowing
space in front of the unit for the heart extension and the mantel, and taking into
consideration the location of the hot air ducts (optional), outside air kit and chimney. If
possible, you should choose a location where the chimney will pass through the house
without cutting floor or roof joists.
B. Usually, no additional floor support is needed for the fireplace. The adequacy of the floor
can be checked by first estimating the weight of the fireplace system. Weights are given in
the appendix. Next, measure the area occupied by the fireplace which is normally 36" ×
26". Note the floor construction and consult your local building code to determine if
additional support is needed.
C. The OSBURN
STRATFORD
may be installed directly on the floor or on a raised base (for
proper guidelines, refer to “Heart Extension Requirements”) and a minimum of 7 feet
(2.15 m) measured from the base of the appliance to the ceiling is required.
3.4.2 Heart Extension Requirements
The OSBURN
STRATFORD
may be installed directly on a combustible floor; however, the
combustible floor in front of the fireplace must be covered with a non-combustible material
(tile, marble, stone, etc.). The hearth extension floor area shall extend at least 16" in front and
at least 8" on each side of the fireplace opening. (see figure 4).
If the fireplace is to be used with
a fireguard, the floor protector in front of the fireplace must have a R value of 1.53 or greater.
