3.2.7.2. Measurement procedure
KR 55
The boiler is equipped with a tower connecting the air intake and flue gas discharge pipes (Figs. 16 and 17).
The tower comes with two openings for direct access to the combustion air and flue gas pipes (Fig. 17).
Remove the caps (A) from these openings (Fig. 16).
The following measurements must be made to determine combustion efficiency.
- measure combustion air taken from opening 1 (Fig. 17);
- measure flue gas temperature and CO
2
from opening 2 (Fig. 17).
The boiler must be working at a steady rate.

3.2.8. Connecting to the gas mains
The cross-section of the gas supply pipe must be equal to or greater than that of the boiler (3/4”).
The cross-section of the pipe depends on the length of the pipe, the layout pattern and the gas flow rate. This means the pipe must be
dimensioned accordingly.
Gas connections must comply with the applicable rules and regulations in the country of installations, which are intended as an
integral part of this handbook.
Please note that before activating an indoor gas supply system and before connecting it to a meter, it must be checked for
leaks.
If any part of the system is not visible, the gas leak test must be performed before the pipe is covered.
The test must NOT be performed with combustible gas. Use air or nitrogen.
If gas is present in the piping, do not use a naked flame to look for leaks. Use a specific product available on the market.
When connecting the boiler to the gas supply fitting, an appropriately sized sealmade of suitable material MUST be used
(Fig. 18).
Hemp, Teflon tape or the like are NOT SUITABLE for use with gas fittings.

The boiler is not equipped with a tower connecting the air intake and flue gas discharge pipes. In this case combustion air, flue gas tem -
perature and CO

are measured at the openings for the accessory pipes, or as close as possible to the air intake and flue gas dischar -
ge point on the boiler.
