INSTRUCTIONS FOR INSTALLATION
General
The Diablo is equipped with a closed combustion cham-
ber.The combustion air is sucked in from outside by a
combined in- and outlet through the natural draught of the
appliance.Through the same natural draught the combus-
tion gases are discharged
Important
• Keep curtains and any other flammable materials at least
50cm away form the appliance.
• Caution! Touching the heater when hot can cause burns
and blisters!
• The appliance should be installed and maintained by a
registered installer.
• Do not install any so-called dust filter on or under the
casing.
• Do not hang wet clothes and towels etc. on the heater
to dry!
Type of gas
Check if the local type of gas and the gas pressure are
similar to those mentioned on the identification plate.
In the factory, the appliance has been adjusted and sealed
for natural gas.
Please keep to the gas installation regulations and any local
regulations. (Gas Safety (Installation & Use) Regulations
1998).
Positioning
• The temperature of the wall behind the appliance may
rise to 60ºC. Please keep this in mind when choosing the
wall and the wall covering.
• The sides of the appliance should be kept accessible
because of the heat the appliance may give off. For this,
allow for at least 50 cm on both sides.
• Allow for at least 50 cm free space to be available above
the appliance for the outlet of hot air.
• Take care that no curtains hang over the appliance
• The appliance should hang at least 10 cm above the
ground.
Possible Connections (fig. 2, page 44)
The heater duct can be connected either through the wall
or the roof, and should meet the following requirements:
• The first metre of pipe should always be fitted vertically;
• The length of horizontal pipe should never be more than
4 metres;
• The maximum length of pipe is 12 metres.
Allow 2 metres for a 90º bend, and 1 metre for a 45º
bend.When mounting the heater on a wall or the roof, the
thickness of the wall or roof does not have to be taken
into account.
The maximum total length is the sum of the pipe length
plus the substitute length for the bends (see the 4 exam-
ples in fig.2, page 44).
The roof duct, the air supply pipes / flue, concentric pipes
and bends are each packed separately and supplied com-
plete with a clip binding with sealing ring. An adjustable tile
or adhesive flashing is also available to seal ducts through
either a slanting or flat roof.
NB: This appliance may only be installed using the flue
material ø150/ø80 supplied by DRU.This has been
approved together with the appliance to comply with all
requirements. DRU cannot guarantee that the appliance
will work correctly and safely if alternative installation
material is used.
Preparations for the installation of the com-
bined inlet-outlet system
• Select the required connection from the options shown
in figure 2 (page 44).
• Erect the concentric pipes from the heater up. If the
structural situation requires that the first section of the
concentric pipe system be built in, take special note of
the required method of assembly.
• The appliance has a coupling section; fit the first metre of
pipe onto this.When correctly assembled, the blue rub-
ber sealing ring inside the pipe should be visible from the
top.
• Allow at least 5 cm between the outside of the concen-
tric pipes and the wall or ceiling.
