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.
• 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.
• Allow at least 5 cm between the outside of the concen-
tric pipes and the wall or ceiling.
Wall duct with concentric pipes
Ensure that the first metre of pipe used for the wall duct
is assembled vertically.
• Determine the position of the appliance and the posi-
tion of the wall duct.
• Decide where to place the appliance and the wall duct.
• To do so, use the backsheet of the appliance.The centre
of the hole for the pipe (when using 1 m of pipe) should
come at 1130 mm above the edge of the backsheet (see
fig. 3 page 27).When using a longer piece of pipe, this
extra length should be added.
• Subsequently, install the backsheet at the right heigth on
the wall (please note the desired level of sight, e.g. bot-
tom backside at 500 mm.The appliance will stick out 82
mm from under the backsheet).
• Then, make a hole of Ø 160 mm (Ø 180 mm max.).
Through flammable material Ø 230 mm.
• Now, connect one or more concentric pipes vertically
to the outlet of the appliance.When these pipes are
located in view, you may order matching varnished
pipes. Press the pipes together and apply the clamping
strip(s).
• Slide the flange over the curve and attach it at 70 mm
from the edge with a self-tapper on the curve.
• Now, slide the curve with flange through the hole and
attach the flange to the wall.
• From the outside, measure the distance between the
outer wall and the edge of the curve. Saw the wall duct
to the length to the measure mentioned below.
The length of the wallduct:
The outer pipe = measured length +30mm.
The inner pipe = measured length +50mm.
• Slide the wall duct into the hole and see to it that the
edge falls within the wall duct. Attach the outer flange
to the wall.
PLEASE NOTE: Level the assembly sheet (2), take care
INSTRUCTIONS FOR INSTALLATION
that the pipes fall to the outside (1cm to 1 m) and that
the outer flange lies directly against the outer wall. In this
way, it will be impossible for any condensation to run into
the heater.

Roof duct with concentric pipes

A duct through a roof can open out anywhere on the
roof, with an extension to the ridge if necessary.
Depending on which of the aforementioned options has
been chosen, the roof duct will be supplied with either
adhesive flashing for a flat roof or a universally adjustable
tile for a slanted roof.
• Determine the position of the appliance and the posi-
tion of the chimney.
• Drill a Ø 160 mm hole at the point where the chimney
is required.Through flammable material Ø 230 mm.
• Now vertically connect the concentric pipes to the
heater outlet. Press well and apply the clip binding.
• Determine the length of the pipes required and ensure
that the adhesive flashing or the universal tile fit properly.
• Saw the pipe off at the length required.
• Connect the roof duct to the concentric pipes.

Fitting the fire to an existing chimney

The fire can be fitted into an existing chimney providing
that the chimney / flue dimensions are 150 mm or more.
A special flue kit is required, which can be obtained from
Drugasar or a Drugasar agent. Do not use any other type
of flue system for this.
BS 5871 – 1 : 2001
Any chimney previously used for an appliance burning a
fuel other than gas shall be swept thoroughly before
installing any gas appliance.
Appliances shall be connected only to the types and sizes
of flue system as specified.
For any other information about this flue system please
contact Drugasar or Drugasar approved agent.
Baffle (fig. 4, page 44-45)
A baffle is needed to ensure the correct working of the
appliance.The baffle is supplied separately and should be
fitted into the appliance as indicated in fig.4a. Using the
adjusting jig provided, (fig. 4b) the baffle can be adjusted
as required. Once it has been adjusted, fix the baffle in
place with the socket-head screw provided.
Adjusting the baffle:
Horizontal wall duct (max. 4 meter)
• 1-meter vertical pipe.
No baffle.
Vertical roof duct
• If the total calculated length of the pipe system is
between 1 and 6 meters.
Baffle at 60 mm.
• If the total calculated length of the pipe system is
between 7 and 12 meters.
Baffle at 54 mm.
