CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 9.3 mbar, relatively to HELIS 2 GI710 2A model, is
measured (
M2
, see chapter 3.6, page 7) with the combustion chamber at 0 mbar using gas G20 with a net
heat value of 10 kWh/m
3
(8.570 kcal/m
3
).
3.
INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.
3.1
WORKING POSITION
The burner is designed for operation in position
1
only.
Installation in positions
2, 3, 5, 6
and
7
is not recommended as it is likely to hinder the unit’s proper operation
since air damper closure cannot be guaranteed when the burner is on standby.
Installation in position
5
is only possible using the “MULTIBLOC rotation kit”, to be ordered separately.
Installation
4
is prohibited as safety is compromised.
