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 efficient 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 effect two concen-
tric 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 instal-
lationt.
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!

5. Flame adjustment settings
Before initial setup, you need to clean the window (from outside and inside) and fire-
place 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.

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.

6. Insulation and nishing
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 wor-
king: 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 ap-
pliance is not too narrowly 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 product. Inflammable mate-
rials as well may not be used for the finishing.
Please , follow this instruction. The appliance can overheat if you do not fol-
low these instructions. Errorcode F02 will appear !
Masonry must be raised around the replace. Due to the expansion
of the replace during combustion, a gap of at least 5 mm must be
provided at the front of the replace and 4 cm on each side of the
appliance. The masonry must not rest on the replace. THE FIRE-
PLACE MUST BE FREE. Always leave 2 mm clearance between the
inner frame and the masonry.
min. 5 mm
A very essential point when setting up the Luna
Gold is that the distance has to be respected
inbetween fireplace and the finishing material for
the mantlepiece such as marble, gipsum,...
For this, a small bended metal sheet that is provi-
ded on the fireplace ( pic.1 ) , is to be used as the
minimal reference for the distance. The finishing
can only go as far as this metal sheet (pic.2 ).
Don’t remove this ( pic.3 ) ! This allows you to
take out the 4th side frame and to let the airflow
in the mantelpiece for natural convection

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 (office, kitchen, ...)
This system directs the heat inside the room using hoses (150mm dia.). It is neces-
sary 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 efficiency of the air outlets 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 applian-
ces 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

to clear the flexible and air inlets and outlets using a vacuum cleaner regu-
