1.1 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 1. The combustion air opening below the ashlip assembly
and the clearance at the sides of the case rear must not be
obstructed.
1.2 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 considerations 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 minimize dust and lint accumulation under the unit. The
recommended minimum hearth size is 32” wide x 15” 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 backdraft conditions may also activate the switch.
1.5 OPTIONAL ACCESSORIES:
The following kit can be used with this appliance:-
#401CVK Concealed Vent Kit required for use with a new zero
clearance type installation. It allows the heater to be installed with
type B metal vent concealed behind a wall or partition and/or in a
chase.
Full installation and operating instructions are supplied with the
kit.
For full details above this kit, contact your dealer.
1.6 POSSIBLE INSTALLATIONS
This appliance can be installed:
1.
As a retrofit
a.
To an existing masonry fireplace and chimney
b.
To an existing factory built zero clearance type fireplace with a
factory built chimney.
The fireplace must be built in accordance with the national, state,
provincial or territorial building code recognized by the authority
having jurisdiction, or the National Fire Protection Association
code in the USA
Any flue damper must be removed or locked open.
The chimney must be swept and both chimney and fireplace
checked for soundness before installation of the heater.
If local codes dictate or if condensation is a problem, a flue liner
must be installed. Use a flue liner that is approved by the
enforcing authority and that is installed in accordance with the
manufacturers instructions. If a flexible liner system is used,
ensure that no sags or dips are allowed to occur where the liner
connects to the heater (figure 2).
2.
Free standing with connection to an approved chimney or vent
maintaining the clearances shown in figure 1.
3.
As a zero clearance installation fitted with the optional
#401CVK Concealed Venting Kit.
This kit allows the heater to be installed with a type B metal vent
concealed behind a wall or partition and/or in a chase. The
venting kit is designed for a 4” round flue. The kit is shown in
figure 3.
Clearances to combustible materials are: Outside edges of
framing plate = 0”. From any part of the flue adapter box
= 1”. Clearances from the connecting elbow are
determined by local codes or, in the absence of local codes,
with the current CAN/CGA1-B149 Installation Code in
Canada or the current National Fuel Gas Code, ANSI
Z223.1 in the USA
