IMPORTANT SAFETY INSTRUCTIONS
20. Keep control compartments, burners and circulating air passages clean. More
frequent cleaning may be needed due to excessive lint and dust. Turn off the
gas valve and appliance (OFF on remote control) before cleaning the appliance.
21. The venting system MUST checked annually by a qualified service person.
If needed, have the venting system cleaned or repaired.
22. When the appliance is installed directly on carpeting, tile or other combustible
material, it must be set on a metal panel or hearth pad extending at least the full
width and depth of the appliance.
23. DO NOT obstruct the flow of combustion and ventilation air in any way. Provide
adequate clearances around air openings into the combustion chamber along
with adequate accessibility clearance for servicing and proper operation.
24. DO NOT use the appliance if any part has been exposed to or has been under
water. Immediately call a qualified service technician to inspect the appliance and
replace any part of the control system and any gas control which has been
submerged in water.
25. DO NOT operate the appliance if any log is broken.
26. The installation must conform with local codes or, in the absence of local codes,
with the Natural Gas and Propane Installation Code, CSA B149.1.
27. This appliance, when installed, must be electrically grounded in accordance with
local codes or in the absence of local codes, with the Canadian Electrical Code,
CSA C22.1.
28. The appliance is equipped with a safety system, whereby the door (front glass
frame) will extract any over-pressure in a controlled way. In this, the door will
briefly open. A safety strip limits the maximum degree to which the door can be
tilted. To avoid any possible personal harm when the door opens due to an
over-pressure, always maintain a minimum distance of 40 in (100 cm) to the
appliance, when igniting and when burning. If an over-pressure situation occurs,
the appliance should be thorougly checked by the installer.
WARNING: Never connect unit to private (non-utility) gas wells.
This gas is commonly known as well-headed gas.
IMPORTANT:
Take care that no pipes get damaged and no compression !ttings come
loose when moving the gas regulator block. Prevent twisting the "exible
pipes# Check all compression !ttings for leaks afterwards#

PRE INSTALLATION INSTRUCTIONS
GENERAL
This ‘direct vent’ gas appliance must be installed by a qualified installer in accordance
with local building codes, or in the absence of local codes, with the current CAN/CSA-
B149.1 or .2 Installation Code
This appliance, when installed, must be electrically connected and grounded in accor-
dance with local codes, or in the absence of local codes, with the current CSA C22.1
Canadian Electrical Code. If you have any queries regarding the installation, please
consult your local gas company.
The appliance is supplied with a “Line Fire” double burner. This burner has a specific
flame image which is defined by the perforation pattern in the burner cover.
See Chapter “DIAGRAM ELECTRICITY AND GAS” and the Operating Manual.
The appliance is factory set to the correct nominal heat input. The pilot light is set to the
correct level of consumption.
The appliance will be delivered from the factory with a 5⅛" x 7⅞" concentric connection
for extracting the flue gases and supply of combustion air.
It is possible to install the appliance with either a wall or roof outlet. The roof connection
must be carried out using a Bellfires adapter (5⅛" x 7⅞" to 5" x 8") together with a
reducer (5" x 8" to 4" x 6⅝") or using a Bellfires adapter (5⅛" x 7⅞" to 4" x 6⅝"), and
the concentric flue system 4" x 6⅝". The fumes are exhausted naturally to the outside
environment through the inner 4" pipe whereas the combustion air supply passes
between the 4" and 6⅝" pipes.
The wall connection must be carried out using a Bellfires adapter (5⅛" x 7⅞" to 5" x 8")
and the concentric flue system 5" x 8". The flue gases are evacuated outside by means
of natural draft through the internal pipe of 5", whereas the combustion air is supplied
between the pipes of 5" and 8".
The appliance can be installed in a completely sealed or mechanically ventilated house
without extra ventilation and/or fume extraction.
IMPORTANT:
Before beginning the installation, check that the details on the rating
plate correspond to the gas type and pressure to which the appliance
will be connected.
WARNING: Due to high temperatures, the appliance should be
located out of traf!c and away from furniture and draperies.
IMPORTANT: This appliance is solely intended for installation
and use in Canada.

PRE INSTALLATION INSTRUCTIONS
The appliance can be installed as an insert into an existing open fire place or as a built-
in appliance in a new fire place. In order to prevent the fireplace heating up excessively,
it must be properly ventilated by installing vents at the top of the fireplace.
The provided barrier safety screen designed to reduce the risk of burns from the hot
viewing glass shall be installed.
If an existing chimney is to be used, please consult your installer first. If the chimney
was previously used for a wood or coal fire, then it should be cleaned by an expert.

The appliance, in combination with the concentric flue system [4” x 6⅝”] and/or [5” x 8”]
(rigid and/or flexible) for the brands, M&G DuraVent (Direct Vent Pro), Selkirk (Direct
Temp) or Metal-Fab (Sure-Seal) has been approved in accordance with the ANSI / CSA
standard for direct vented gas appliances and may therefore be used only with these
systems.
The permitted components for these systems are listed in Chapter “Vent Installation”.
The guarantee on the appliance lapses if it is installed, fully or partially, with other
components or a different flue system.
The concentric flue [4” x 6⅝”] and [5” x 8”] systems can be used with either a newly-built
or existing chimney.

CLEARANCES
WARNING: Follow these instructions carefully to ensure safe
installation. Failure to follow instructions exactly can create a !re hazard.
UNIT MUST SIT ON NON COMBUSTABLE SURFACE
The appliance must be installed on a non-combustible "oor. If installed on, for
example, carpet or vinyl "ooring, the appliance shall be placed on a plate of non-
combustible material extending the full width and depth of the appliance.
All clearances to combustible and non-combustible materials must be maintained as
described in this manual.
Clearances are in accordance with local installation codes and the requirements of the
gas supplier.
Never use combustible materials during the installation.
During installation of the appliance, a clearance of ⅛" (3 mm) should be maintained on
all sides of the appliance to allow for expansion of the appliance during operation.
Do not insulate the appliance! Only the top and sides may be fitted with a strip of white,
loose insulation wool (heat-resistant to 1832°F (1000°C)), width 6" (15 cm) max. to
protect the wall.
Do not use fibreglass or Rockwool, or any other sort of insulating material. These emit
a pungent odour. This is considered extremely unpleasant. They may also cause
discolouring of the column.
Combustible materials, such as curtains, should not be placed in the vicinity of the
appliance. Minimum safe distance: 40" (100 cm).
Never place the appliance directly to a combustible or non-combustible rear wall and
side wall.

Ventilation
Ventilate the fireplace/chimney breast:
• all spaces between the appliance and the insulation plates
• all spaces between the insulation plates an all surrounding walls
by allowing vents above.
With false ceiling:
Minimal required net vent openings above must be total 46 sq ins (300 cm2).
This can be done by ventilation openings or grills.
The design of the ventilation openings/grills is free to choose.
Place the ventilation opening/grills at minimal 5" (12.5 cm) distance under the ceiling,
to prevent discoloration.
See also figure 2 and 4.
Without false ceiling:
Between the top of the fireplace/chimney breast and the ceiling there must be a total
open space.
The minimal required sizes of this open space are given in figure 2 and 4.
Non-combustible insulation plate/board
Any used insulation plates must have a maximum thermal conductivity of
0.69 BTU / (ft2.h.°F/in) (0.10 W/m.K).
Suitable insulation materials are listed in table 1.
Do not use fibreglass or Rockwool, or similar material. These materials emit a pungent
odour, which is considered extremely unpleasant.
