3.2.7.2. Measurement procedure
The boiler is equipped with a tower allowing for air intake/flue gas discharge duct connection (fig. 19 and 20). The tower is designed with two pre-
arranged openings directly accessing air and flue gas ducts (fig. 20).
Remove cap A from the pre-arranged openings on the tower, before starting combustion checking procedure (fig. 19).
In order to verify combustion performance the following measurements must be implemented:
- assess combustion air from no. 1 opening (fig. 20).
- assess flue gas temperature and CO
2
from no. 2 opening (fig. 20).
Allow boiler to reach working temperature before performing any measurement.

3.2.8. Gas mains connection
Gas supply pipe cross-section must be equal or greater than boiler gas pipe.
Cross-section gas pipe size calculation depends on its length, layout pattern, gas flow rate. Gas pipe size is to be dimensioned accordingly.
Comply with installation standards enforced in the installation country which are considered as fully transcribed in this booklet.
Remember that before operating an indoor gas distribution system and before connecting it to a meter, it must be checked
for leaks.
Adhere to the following leak test instructions:
- leak test is to be carried out before pipes are covered;
- leak test is NOT to be carried out employing flammable gas: use air or nitrogen for this purpose;
- when gas is already in the pipes supplying the boiler, leak testing by naked flame is forbidden, use specific products
available on the market.
When connecting the boiler to gas supply network, it is COMPULSORY to install an appropriately sized and made gasket (fig.
21). The boiler gas inlet thread configuration is NOT appropriate for hemp, plastic tape or similarly made gaskets.
