5. COMMISSIONING
5.1.
Checks before commissioning
For a cascade installation, check the hydraulic balancing of the boilers.
Check the water pressure on the manometer. This must be a minimum of 1
bar when cold.
Check that the gas pressure and type are suited to the products.
If the gas mains supply is at 300 mbar, check that a regulator is installed
upstream of the boiler on the gas supply pipe.
Check that the boiler and its installation are completely bled (check the boiler
levelling with a spirit level).
If this is a boiler renovation, ensure that the installation has been
correctly flushed and silt removed if necessary (see the section 1.5 of
this manual).
Check the exhaust connection according to the type of chimney (see section 4.2).
ATTENTION:
If there is a B23–B23P chimney connection, it is ESSENTIAL to use
the "Chimney adaptor" accessory consisting of:
- an air intake grille
- a filter sheet
- an adaptor duct
5.2. Commissioning
Before packing all boilers are subjected to a factory test using group H
(type G20) natural gas during which all the settings are done.
For commissioning perform the following operations:
1. Switch on the main circuit breaker.
2. Initiate a request for heat via the comfort mode using the customer
interface (see chapter
in the NAVISTEM B3000
boiler controller manual).
3. After starting the burner, check the gas tightness of the gas line connections
using a foaming product. Check combustion health using an exhaust gas
analyser.
4. Adjust the boiler setpoint (refer to the table summarising customer
parameters at the end of this manual).
ATTENTION:
Any work on a sealed component will lead to loss of the guarantee.
