Discoloration Of Walls And Ceiling; Lighting The Heater For The First Time; Extra Protection; Disposal - Dru DIABLO Instructions D'installation

GENERAL NOTES

Discoloration of walls and ceiling

Brown discoloration is an annoying problem, which is diffi-
cult to solve. It can be caused by dust burning as a result
of poor ventilation, for example, or by cigarette smoke or
candles.
These problems can be avoided by ensuring that the room
the heater is in is properly ventilated. A good guideline for
ventilation is:
New buildings : 3.24 m
surface of the room.
Existing buildings : 25.20 m
Use candles and oil lamps as little as possible, keeping the
wick as short as possible.While they enhance the atmos-
phere, candles and oil lamps also cause the formation of
large quantities of unhealthy soot particles in your home.
Cigarette and cigar smoke contains tar, which upon heating
will precipitate on cold or damp walls. If you have a newly
cemented chimney or have had any other reconstructions
/ renovations done, you are advised to wait at least 6
weeks before lighting your fire, to allow the walls, floor
and ceiling to dry out completely.

Lighting the heater for the first time

During the first use, an unpleasant smell may occur, caused
by the vapour of the varnish.This will vanish after some
hours.
That is why we advise you to use the appliance for the
first time on its highest setting, while at the same time
thoroughly ventilating the room in which the heater is
placed.

Extra protection

This heater meets the normal safety standards regarding
surface temperatures, but physical contact with heated
surfaces should be avoided where possible. An additional
guard is recommended to protect young children and eld-
erly, infirmed or handicapped people.

Disposal

When replacing or otherwise removing the appliance, it
should be disposed of in compliance with current
regulations.

mencing disassembly. Undo the coupling between the con-
necting tap and the appliance.The whole appliance can
now be disassembled and removed.
