1. General remarks
This is an appliance using the closed combustion system, designed for the atmosphere and
comfort of your living-room. It constitutes an ecient source of heat and gives the
impression of a real fire.
The balanced flue appliances are based on the principle of natural extraction from the
firebox, which eliminates flue gas outside and brings in air (oxygen) from outside the house
which is necessary for combustion of the gas. It uses to this eect two concentric pipes.
The internal pipe ensures the elimination of burned gases and the external pipe brings in
combustion air. The advantage of this principle is that the equipment works independently
of the atmosphere which predominates in the house.
2. Connection
This appliance must be connected by an approved installer in accordance with the most
recent
regulations in force. On the basis of your order specifications, this appliance is designed for
natural or propane gas.
Read the instructions before installing and using this appliance. Before installing the
appliance, please check the local regulations about this type of appliance (identification of
the type of gas, etc.) and check that the furnace is adapted to your means of installationt.
It is imperative that the installer sees to the following:
•The appliance must be subject to an air tightness test of the gas and elimination of flue
gases.
•The concentric pipe, if already available, must be working correctly.
•The running of the control valve, lighting of the pilot light, the main burner and the
thermocouple must all be checked.
This appliance has been programmed and factory sealed. The sealed parts cannot be
modified. The appliance may therefore also be installed in airtight accommodation and
accommodation equipped with mechanical ventilation. It constitutes ambient heating even
in accommodation equipped with a closed ventilation system.
The appliance must be connected to the type of gas mentioned on
the appliance. Never connect a propane burner to natural gas or vice
versa!

Before initial setup, you need to clean the window (from outside and inside) and fireplace of any dust
and grease. If you do not clean the glass properly, after lightning up the fireplace it can
remained still on the glass. After installing the fireplace correctly on the concentric tube or chimney
system, you must make a flame adjustment according to the draft (see chapter 4 page9. Installing the
chimney + use restriction rings).
The air intake for flame can be adjusted in fireplaces. Setting element is situated on the left side of the
bottom plate in the combustion chamber. Adjustment of air intake may only be set out by a specialist.

6. Insulation and finishing
Once installation is complete, the appliance can be fitted. Before doing so, check the tightness of the gas
pipe one more time. Light the appliance and check that it is working: check the tightness of the gas pipe
and the smoke pipe. Once you have checked everything, you can perform the final insulating and finishing
operations.
The built-in part of the appliance tends to be very warm. Please check that the appliance is not too nar-
rowly fitted and that there is adequate space for the elimination of hot air. For insulation of the appliance,
we advise you to use M Design insulating plates. You are advised against using any other insulation pro-
duct. Inflammable materials as well may not be used for the finishing.
Please , follow this instruction. The appliance can overheat if you do not follow these
instructions. Errorcode F02 will appear !
Masonry must be raised around the fireplace. Due to the expansion of the fireplace
during combustion, a gap of at least 5 mm must be provided at the front of the
fireplace and 4 cm on each side of the appliance. The masonry must not rest on the
fireplace. THE FIREPLACE MUST BE FREE. Always leave 2 mm clearance between
the inner frame and the masonry.

VISION, VENUS GAS. Setting element is situated on the left side of the bottom
plate in the combustion chamber. Adjustment of air intake may only be set
out by a specialist.
It is needed to wait 30-60 minute until the setting is fully showen up in the
fired fireplace. . Natural gas is first burning by blue colour and it will turn
yellow in time, LPG burning become quicker yellow.
If the flame is blue, it can mean that there is too much air in the combustion
chamber but also that there is too little air. If there is too much air, the flame
move very quickly.
Attention, burner have to burn continuously evenly in the whole
length included secondary burners.
By adjusting the flame cannot remove up from burner (cannot be
separated flame from burner), it is really dangerous. Then there is
too little air in combustion, in this case, add air by moving the
regulation element to the right side.
By adjustment must be taken to account that the more yellow the flame is the
quicker glass can get dirty.

7. Convenction current
It is MANDATORY to equip the fireplace with a convection kit consisting of inlets and outlets which are
connected to stretchable hoses from 3m to 5m.
In this way is created a circualtion and evacuation of the heat by convection.
This is very important to avoid overheating in the firebox casing and also to distribute the air hot air in the
room or in another adjacent room (oce, kitchen, ...)
This system directs the heat inside the room using hoses (150mm dia.). It is necessary to open minimum
2 hot air outlets. For the installation of these ducts, limit their lengths, avoid as much as possible elbows
and changes of direction, because the losses of speed generated, decrease the eciency of the air out-
lets at the end of travel. We advise you to install the hot air grilles at the same height to have the same
heat provided. M-Design has developed hot air and ambient air outlet grilles available from your dealer (see
page 16).
Outlet grids have two or four hose connections (2/4 hoses on 1 grid!).
The air inlet grilles (not to be connected with a hose) must be placed as low as possible at the bottom of
the fireplace.
Please, follow this instructions. The appliance can overheat if you not apply those instructions.
Errorcode F02 will appear!
ATTENTION : A house is never completely 100 % dustfree, heating appliances and warmth
circulation create dust particles. During the periods where you are not using the fireplace,
dust is accumulated in the flexible pipe and and the grills
This could cause a problem with a smell, so we would certainly advise you to clear the
flexible and air inlets and outlets using a vacuum cleaner regularly. The smell caused by
these dust particles will disappear after you have used the fireplace again a few times.
(This phenomenon is very common and can be compared to the gray traces
appearing above your radiators.) Optionally you can order design metal lids to cover the
inlets and outlets during the summertime .
