CLEARANCES
Make sure that the minimum clearances to
combustible materials are maintained during
installation including adequate space for the
proper operation and servicing of the heater.
The minimum clearances from the heater to
combustible materials are shown in
figure
7.
The combustion air opening below the apron
and the air intake slots at the sides of the case
rear must not be obstructed.
FLOOR
Do not place the heater on carpeting, vinyl or
other soft surfaced floor coverings. Install only
on hard surfaced materials.
It is recommended for aesthetic considera-
tions and ease of maintenance that the
heater is installed on a hearth finished with
brick, ceramic tile, marble etc. Raising the
hearth slightly will help to minimise dust and
lint accumulation under the unit. The
recommended minimum hearth size is
32"
wide x 12" deep.
If however, the heater is installed directly on
flooring of combustible material other than
wood, it must
be
installed on a metal or wood
panel extending the full width and depth of
the heater.
1.3. DRAFT
HOOD
This heater has a draft hood built into its back
and draws its air from either side. It must not
be altered or obstructed. The draft hood must
be in the same atmospheric pressure zone as
the combustion air inlet to the heater.
1.4.
VENTING
This heater is a vented appliance and must
be connected to a chimney or flue in
accordance with the national and local codes.
For added safety, this heater is equipped with
a vent sensor system which will react to
incorrect venting by shutting down the gas
supply. The thermally activated sensor switch
is located within the draft hood to detect either
a blocked or disconnected vent. Certain back-
draft conditions may also activate the switch.

ance type installation. It allows the
heater to be installed with type B metal
vent concealed behind a wall or partition
andlor in a chase.
iii)
#SO1
PVK
Power Vent Kit
Allows the heater to be vented through
a sidewall (horizontally).
