INSTRUCTIONS FOR INSTALLATION
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
rubber sealing ring inside the pipe should be visible from
the top.
• Allow at least 5 cm between the outside of the
concentric pipes and the wall or ceiling.
Wall duct with concentric pipes
Ensure that the first 1,4 metre of pipe used for the wall
duct is assembled vertically.
• Determine the position of the appliance and the position
of the wall duct.
• Drill a Ø160 mm hole at the point where the wall duct is
required.
• Now vertically connect one or more concentric pipes to
the heater outlet. Press well and fit the strip(s) of clip
binding. The blue rubber ring will sufficiently seal the flue
system.
• Place the bend on top of this, fit any horizontal concentric
pipes required, and make sure the connections are
gastight.
• Connect the wall duct to the bend or the horizontal pipes
and make sure that this connection is also gastight.
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 position
of the chimney.
• Drill a Ø 160 mm hole at the point where the chimney is
required.
• Now vertically connect the concentric pipes to the
heater outlet. Press well and apply the clip binding. The
blue rubber ring will sufficiently seal the flue system.
• Determine the length of the pipes required and ensure
that the adhesive flashing or the universal tile fit properly.
• Saw the outside pipe off at the length required.
• Connect the roof duct to the concentric pipes.
NB: Alternatively, you can fit the concentric pipes before
installing the heater. In that case the connection to the
outlet of the appliance should be made using a length of
pipe that can be shortened later.
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.

works satisfactorily,
it will need to be adjusted
according to the
customer-specific pipe system.

Using a roof duct:
Adjusting the baffle.
The baffle is supplied separately and should be fitted into
the heater as indicated in fig. 6. Use the adjustment jig
provided (fig. 5) to adjust the baffle to the right size. Once
it has been adjusted, fix the damper in place with the
socket-head screw.
• Adjust the baffle according to the calculated total pipe
length of between 1 and 12 m, (figs. 1, 2 & 3), as follows:
1 - 3 m: adjust damper to 33 mm
4 - 8 m: adjust damper to 27 mm
9 - 12 m: adjust damper to 23 mm
Slide the baffle in as far as it will go, the opening will
automatically be 23mm.
NB: The maximum length of vertical pipe is 12 metres.
Using a wall duct:
For the following applications, the adjustments required
are:
• 1,4 metre vertical pipe with a 90° bend and a wall duct:
adjust damper to 39 mm
• 1,4 metre vertical pipe with a 90° bend and max. 3
metres horizontal pipe and a wall duct.
