Floor Protection Requirements
The Oakwood must be installed on a non-combustible
floor or a non-combustible floor protector. Floor protection,
when not using the optional bottom heat shield, must be
a minimum 3/4" (19mm) thickness of material having an
insulating value equal to or better than 0.84k/in. (The lower
the k value, the better the protection.)
Another method for calculating floor protection is in R
value. This requirement would be for an R value of 0.89 or
higher. (The higher the R value, the better the protection).
In all installations, the area under and around the stove
must be protected from falling ash and live coals. The area
under a horizontal run of chimney connector must also be
protected, extending two (2) inches beyond the measurement
of the horizontal connector.
Further guidelines for floor protection are as follows:
In the U.S. the floor protector must be completely under
the stove, and extending 16" in front of the door opening,
8" to each side and 8" to the back.
In Canada, the floor protection must extend 18" (457mm)
in front of the door opening, 8" (203mm) to each side and
extend to the wall behind the stove.
Clearances
Clearance is the empty space required between the stove
or chimney connector and the nearest combustible surface or
object, such as walls, ceilings, floors, or furniture. Clearance
distances may only be reduced by using methods approved
by either the CAN/CSA B365 standard (Canada) or NFPA
211 (U.S.) Contact your building authority for information
if you are interested in reducing clearance distances other
than those presented here.
Parallel versus Corner Installations
A parallel installation is one in which the back and sides
of the stove are parallel to the walls behind and to the side
of the stove. A corner installation is one in which the back
of the stove is positioned diagonally across a corner of the
room. Each installation requires its own set of clearances.
InStallatIOn
For parallel installations, the required clearance dis-
tances from the stove are: (see next pages for more details,
including the use of double walled pipe and optional heat
shields)
1) to the side wall, 26" (661 mm);
2) to the back wall, 28" (712 mm).
3) From the flue connector to the wall, 33" (839mm)
4) Horizontal pipe to the ceiling, 15"(381 mm).
NOTE: For a vertical chimney connector in a parallel
installation the distance of the connector to the side wall must
be 32"(813 mm), due to the required side clearance of the
stove itself. Fireplace installations must meet these same
clearance requirements; specifically follow these guidelines
for mantel and trim clearances.
For corner installations, the clearance distances from the
stove are 24"(609 mm) from each corner of the stove mea-
sured straight back to the nearest combustible material, and
32" (813 mm) from the chimney connector to the walls.
From the front of the stove, clearance to combustible
materials such as furniture, curtains, fuel, etc., is: 48"(1220
mm) in the U.S. and 60"(1524 mm) in Canada.
