Instructions for the Installer
- Always respect the rules in force in the country in which the device is installed. In France, the
drainage systems of the combustion products is in conformity with the DTU 24.1 in February 2006.
- Make sure the flue is in a good condition. Its role is crucial. It will influence the final result by
ensuring the supply of primary air in homes and extracting the gas combustion.
The most common problem experienced is due to chimney failures.
- A good chimney must be a poor conductor of heat and able to retain its heat well.
- The minimal diameter of the flue for operation with closed door is 150mm, can be subject to the
sizing of pipe smoke, according to EN 13384.1 authorizes this dimension. As soon as possible, we
recommend the use of a flue having an inside diameter of 180mm.
-Not a single reduction of the flue, even at the top outlet is permissible as it may cause a reduction of
fume exhaust, which can provoke some down draught in the room when opening the door.
-The chimney must originate from the same place in which the unit is installed.
- Check the air intakes are free from obstruction.
- The flue must be perfectly sealed.
-The flue pipe or tubing used must be designated G, that is to say of fire resistant material. Equipment
must be connected to the designated 50deg C above the temperature declared for the device
regardless of the connected mode.
-The height must not be lower than 5 meters with a reasonable upper clearance in fresh air of 0.40m
minimum above the pitch of the roof or from any other obstacle at a distance of no less than 8m from
the conduit.
-The draught should be between 1.5mm CE and 2mm CE during normal functioning, and dropping to
0.5mm CE on slow running. The draught must not come down below 1.2mm CE in normal running
mode.
.-If the cross section of the flue/chimney is oversized, heating up the volume will be too large and the
draw will not establish itself normally.
All casing shall be consistent with the DTU 24.1. The design responds to the precise rules for
calculating (EN 13384.1) that only a professional is able to define.
-Do not use clay flue accessories having an outlet section of 2.5dm2 minimum.
-It is recommended to fit a well sealed cleaning trap at more or less 50cm below the heater outlet.
-Before connecting, make sure that the chimney is perfectly clean; if necessary have the chimney
swept.
-The appliance to be installed according to the current DTU specifications in force, and installation by
a qualified professional. All local and national regulations must be respected.
-The extractors used in the same room or in the same space that the heater is situated, can
dangerously disrupt the operation of it.
-The simultaneous operation of other devices in the same space as the unit can generate
disturbances of circulation.
-Never block the air intake of the room and install it in a manner that it cannot be obstructed, the
heater takes air from the room therefore it is necessary to ensure sufficient air intake from outside.
-The factory fits the spigot at the rear of the appliance. It can be connected directly to a chimney by a
horizontal pipe. It can also be connected on top and in that case, interchange the plate and the
spigot.
