Fig. 11 Combustible supporting timbers (A) may lie beneath
fireplace hearths; such situations require additional floor
protection.
Floor Protection for Fireplace Installations
You may install your Dutchwest Convection Heater in
an existing fireplace as a fireplace insert with no legs,*
or with the standard legs attached.
To install the heater without legs as a fireplace insert,
the floor must be completely noncombustible, such as
an unpainted concrete floor over earth.
Many fireplaces do not satisfy the “completely non-
combustible” requirement because the brick or con-
crete hearth in front of the fireplace opening usually is
supported by heavy wooden framing as in Figure 11.
Hearth rugs do not satisfy the requirements for floor
protection.
REMINDER- FIREPLACE INSERT INSTALLATIONS
WITHOUT LEGS ARE PERMISSIBLE ONLY IF THE
HEARTH IS COMPLETELY NONCOMBUSTIBLE,
SUCH AS UNPAINTED CONCRETE OVER EARTH.

Because heat passes readily through brick or concrete,
it can easily pass through to the wood. As a result,
such fireplace hearths are considered a combustible
floor.
You may not install a heater on a combustible
hearth without legs. Standard leg installations must
include the bottom heat shield.
The floor protector
must also meet standard requirements for freestanding
installations.
Floor Protection for Fireplace
Installations with Standard Legs
Fireplace installations with the standard legs and the bot-
tom heat shield must have a floor protector of the same
construction as that specified for freestanding installa-
tions. The floor protector must extend at least 300 mm
(12”) from the front of the stove and from the left (loading
door) side, and at least 150 mm (6”) from the right side
and rear. It must also provide protection beneath any
horizontal runs of the chimney connector, including 51
mm (2”) to either side.
Many raised hearths will extend less than the required
distance from the front of the heater when it is installed.
In such cases, sufficient floor protection, as described
above, must be added to extend the hearth 406 mm
(16”).
Keep the Stove a Safe Distance
From Surrounding Materials
Both a stove and its chimney connector radiate heat
in all directions when operating. A safe installation re-
quires that adequate clearance be maintained between
the stove and nearby combustible materials to ensure
that such materials do not overheat.
Clearance is the distance between either your stove or
chimney connector, and nearby walls, floors, the ceiling,
and any other fixed combustible surface. Keep furnish-
ings and other combustible materials away from the
stove as well. In general, a distance of 1220 mm (48”)
must be maintained between the stove and moveable
combustible items such as drying clothes, furniture,
newspapers, firewood, etc. Keeping those clearance
areas empty assures that nearby surfaces and objects
will not overheat.
