Baffle; Connecting The Gas Supply - Dru Verwarming CONCERTO Instructions D'installation Et Mode D'emploi

Baffle

To ensure that the heater works properly, the baffle should
be fitted in such a way that the heater can be adjusted
according to the customer's pipe system.
The baffle is supplied separately and should be fitted into
the heater as illustrated in fig. 7. Once it has been adjusted,
fix the baffle with the socket screw.
Adjusting the baffle:
• If the total length of the pipe system has been calculated
to between 1-12 m (examples 1, 2 & 3).
Baffle at 40 mm.
Slide the baffle in as far as it will go, the opening will
automatically be 40 mm.
• If connected with 1-1.5 m vertical pipe, a 90° bend and a
wall duct.
No baffle.
• If connected with 1-1.5 m vertical pipe, a 90° bend and
then 1-4 m horizontal pipe, as shown in example 4.
No baffle.
Fig. 3 illustrates how to calculate the total lengths.
INSTRUCTIONS FOR INSTALLATION

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.
