Floor protector’s come with various types of
specifications. To convert a floor protector’s specification
to an R-value, do one of the following:
•
If the R-value is given, use that value—no
conversion is needed.
•
If a K-factor is given with a required thickness
(T) in inches, use this formula: R-value = 1/K x
T
•
If a C-factor is given, use the formula: R-value =
1/C
To determine the R-value of the proposed alternate floor
protector:
•
Use either the K-factor or the C-factor formula
explained above to convert specifications not
expressed as R-values.
•
For multiple layers of floor protectors, simply
add the R-values of each layer to determine the
overall R-value of the layers.
If the overall R-value of your setup is greater than the
R-value of the specified floor protector, then your setup is
acceptable.

Handle Assembly
Locate the handle, bolt, and washers enclosed in the
envelope with the owner’s manual. Place the washers on
the bolt and then push it through the handle so that the
bolt threads extend through the bottom of the handle.
Using a slotted screwdriver, turn the bolt into the chrome
latch on the door, until snug.
Handle Operation
Front Door – when closed, the handle will be in the 7
o’clock position. To open the front door, rotate the latch
clockwise to approximately the 10 o’clock position.

counter-clockwise to approximately the 6’clock position.
Side Door – when closed, the handle will be in the 5

(Kit #90-53210)
An outside air source may be connected directly to this
stove using an optional outside air kit. The advantage of
providing outside air directly to the stove is that the air
used by the stove for combustion is taken from outside of
the residence rather than from within the room where the
stove is located. With outside air supplied directly to the
stove, drafts within the room and air infiltration within the
building are reduced. Use of the outside air kit may also
improve stove performance in a particularly airtight
house.
The outside air kit for this stove allows for the direct
connection of the stove's air intake to a minimum 3" (76
mm) diameter duct (supplied by others) which leads to the
outside of the house. When considering placement of the
duct from the outside of the house to the hearth, keep in
mind the need to avoid structural members of the house.
The outside air kit will attach to the back of the stove.
The termination of the duct on the outside wall of the
stove should be located in such a manner so as to preclude
the possibility of obstruction by snow, leaves or other
material and should be screened against animals and
insects. The termination should be screened using
¼” x ¼” mesh rodent screen and be covered with a
rain/wind proof hood (flex pipe, outside termination,
mesh, and hood supplied by others) Contact your dealer
for availability).
