GENERAL NOTES

GENERAL NOTES
Gas Safety Regulations (for installation & use) 1998
In your own interest and that of safety, it is law that
all gas appliances are installed by competent persons in
accordance with the above regulations. Failure to install
appliances correctly could lead to prosecution.
NB: The Confederation of Registered Gas
Installers, whose members are identified by the
emblem shown here, are all required to work to
the recognised standards.

Cleaning and Maintenance

The appliance should be inspected once a year by a
qualified company, and cleaned and/or repaired as neces-
sary.The inspection and maintenance must at least ensure
that the appliance is working correctly and safely.This
can be done by your own gasinstaller or a specialised
maintenance company. You are recommended to free the
heater of dust before and occasionally during the heating
season.Do not use abrasives when cleaning the heater.
Damage to the casing varnish, caused by anything being
put on the appliance, is not covered by the guarantee.
NB: When replacing the pilot light burner, the coupling
nut in the gas control block should first be tightened by
hand and then tightened a quarter-turn with an
open-ended spanner.

Discoloration of walls and ceiling

Brown discoloration is an annoying problem, which is
difficult 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 atmo-
sphere, 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 heat-
ing will precipitate on cold or damp walls. If you have a
newly cemented chimney or have had any other recon-
structions / 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.
3 / hour per m 2 floor
2 / hour for a room.

Lighting the heater for the first time

There can be an unpleasant smell when you light the
heater for the first time. This is caused by the varnish
evaporating and will disappear after a few hours. We
therefore advise you, on initial use, to heat the appli-
ance at the highest setting while ventilating the room it is
installed in well.

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
elderly, infirmed or handicapped people.

Disposal

When replacing or otherwise removing the appliance, it
should be disposed of in compliance with current regula-
tions.
Shut off the connecting tap with coupling before com-
mencing disassembly. Undo the coupling between the
connecting tap and the appliance. The whole appliance
can now be disassembled and removed.

Guarantee

The warranty for your DRU appliance will be provided by
your supplier. In case of malfunctions, you should always
contact him. You supplier will contact DRU if he feels this
is necessary. The factory warranty for your appliance is
valid for 2 years after date of purchase.
