Checking CO
2
settings
The burner is factory set to natural gasE.
During commissioning or maintenance, check the CO
2
level on the boiler
adaptor.
Please note:
The MatriX burner is preset for the entire gas group. Therefore, the burner
requires no further setting or adjustment.
Subject to the Wobbe index, the CO
2
content ranges between
H
6.6 and 9.5
% for natural gasE and
H
7.0 to 9.0
% for natural gasLL.
Compare the actual CO
2
value with the above CO
2
value ranges for the
individual gas groups (check the gas group with your gas supplier).
If the actual CO
2
value deviates from the stated ranges by more than 1
%,
proceed as follows:
H
Check that the correct gas restrictor has been installed (see page9).
H
Carry out a leak test on the balanced flue system (see page14).
1.
Connect a flue gas analyser at
boiler adaptor
A
("flue gas"
port).
2.
Start up the boiler.
3.
Operate the boiler at its lower
rated output (see page26) and
check the CO
2
content.
4.
Operate the boiler at its upper
rated output (see page26) and
check the CO
2
content.
5.
Terminate the manual mode (see
page26), and enter actual values
into the service report (from
page46).
