Fitting The Fire To An Existing Chimney; Baffle/Sliding Air Valve; Connecting The Gas Supply - Dru Verwarming CELLO C11 Instructions D'installation Et Mode D'emploi

• 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.

fig. 4
Adjusting the baffle.
The baffle is supplied separately and should be fitted into
the heater as indicated in fig. 5. Use the adjustment jig
provided (fig. 4) to adjust the baffle to the right size. Once
it has been adjusted, fix the damper in place with the
socket-head screw.
Removing the sliding air valve, see fig. 6: remove the back
burner by unscrewing the two self-tapping screws (2).
Undo the three wing-nuts (3) and remover the two-part
sliding air valve (1). Replace the burner.

Connecting the Gas Supply

An approved connecting tap with coupling should be used
in the supply hose (In Belgium this must be B.G.V. approved).
Furthermore:
• Expel all air from the supply pipes/hoses before coupling
to the appliance.
• Do not turn the coupling tap when connecting it to the
gas supply.
• Avoid any pressure on the control tap and pipes.
• Check that all connections are gastight.
