INSTRUCTIONS FOR INSTALLATION
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
concentric 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 position
of the wall duct.
• Drill a Ø160 mm hole at the point where the wall duct is
required.Through flammable material Ø 230 mm.
• Now vertically connect one or more concentric pipes to
the heater outlet. Press well and fit the strip(s) of clip
binding.
• 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.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 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.
