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 1110 mm above the edge of the backsheet (see
fig. 3 page 45).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.).
• 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).The blue rubber ring will supply sufficient sealing
of the combustion gas discharge system.
• 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
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 ∆ 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.
INSTRUCTIONS FOR INSTALLATION

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.

Restriction

To ensure that the heater works properly, a restriction
should be fitted in the top of the combustion chamber.
The restriction is a small square of metal sheeting with a
hole in it, supplied with the roof duct. If the total height
of the pipes is more than 4 metres, the 40 mm restriction
should be used. If the total height is 4 metres or less, the
49 mm restriction should be fitted.
The second drawing in fig. 2 page 00 illustrates how to
calculate the total height. In the example the horizontal
lengths have been disregarded so that the total height is 5
metres. In this case the 40 mm restriction should be fit-
ted. Fix the restriction with the sheet metal screws pro-
vided.
For a horizontal wall duct with one metre vertical pipe,
no restriction is necessary.

Glass window

For the placing of the logs, the window should be
removed.To do so, proceed as follows:
• Remove the four screws of the safety strip of the win-
dow
• Take away the strip and subsequently the glass window.
• Make sure that the standing corner strips do not fall.
To re-assemble the glass window please follow the proce-
dure in reverse order.
When doing this, make sure that the glass window
securely seals the combustion chamber.
Broken or otherwise damaged glass should be replaced
immediately.
For safety reasons a guard should be placed in
front of the fire at all times.
