Important - Rational CPC Serie Manual De Instalación

Important!

To ensure that the burner settings made at the factory conform with the actual installation conditions, the
waste gas (C0, C0 2 ) from the steam and hot-air burners must be analysed during commissioning. The
corresponding values must be documented inside the unit. If the undiluted C0 values are above 1000 ppm,
the burner settings must be checked and if necessary adjusted by engineers trained and certified by the
company.

Gas connection
Comply with local gas authority regulations!
Follow installation instructions!
• Check that the gas type supplied is suitable for the unit.
• The diameter of the pipe must comply with local regulati-
ons (DVGW-TRGI ´86 or TRF 1988).
• External thread of gas connection:
• Gas stop valve supplied for each unit.
• Gas connection with gas outlet socket only possible on
6x1/1 GN units.
• All gas supply connectors must comply with local regulati-
ons (DIN-DVGW).
• The unit must be secured against movement.
• Check the gas supply line for leakage.
The unit is only to be connected to the gas supply
by a locally approved gas installer. It is vital to ensue
that the gas connection pipes as well as the
connection pipes for the associated gas metering
systems match the stipulated pipe widths.
Warning!
If the flow pressure deviates from the specified flow pressure
(see table), inform the gas authorities. If the flow pressure of
natural gas exceeds 30 mbar, the unit must not be switched
on and the gas supply must be disconnected.

• Check that gas exhaust pipes are leakproof, in accordance
with local regulations (DVGW-TRGI ´86 or TRF 1988).
• Aluminium exit pipes should be avoided due to exit gas
temperatures in excess of 200°C.
Gas exhaust system can be connected to the following in
compliance with DVGW Instruction Sheet G634:
pic. 3 1. Extractor hood
2. Fan roof
3. Directly to the flue
Room ventilation
The rooms in which these appliances are installed must be
well ventilated, in order to prevent an unacceptable build-up
of harmful combustion products.
We recommend that your gas installation is serviced
once a year in accordance with the specified
standards.
