5.9 Commissioning
General
Commissioning requires the use of a CO/CO
2
flue gas analyser with an inaccuracy < 0.1% and
two pressure gauges.
For measuring gas pressure a resolution of 0.1
mbar or better is recommended.
For measuring offset pressure a low range
gauge with a resolution of 1 Pa or better is
required.
M Series Heaters
Modular M Series heaters have two burners
which must be commissioned sequentially, a
Master controlled by contact T1 in the control
section and a Slave controlled by contacts T2A
and T2B.
T1, T2A and T2B contacts all closed
The Master burner MUST be commissioned first.
To commission the master burner, isolate the
Slave burner by opening contacts T2A and T2B.
T2A and T2B contacts open, T1 closed
Once the slave burner has been isolated,
commission the master burner following the
commissioning procedure given overleaf.
Once the master burner has been
commissioned, the slave burner must be
commissioned. To commission the slave burner,
the master burner must be isolated. To isolate
the Master burner and commission the Slave,
open contact T1 and close T2A and T2B.
T1 contact open, T2A and T2B closed
Once the master burner has been isolated,
commission the slave burner following the
commissioning procedure given overleaf.
When the Master and Slave have individually
been commissioned, the correct operation of
the complete appliance must be verified in the
following manner:-
1. Ensure T1, T2A and T2B are all closed and a
heat demand is present.
2. The Master burner will fire first followed by
the Slave after a short delay.
3. Check the CO/CO
2
values to ensure safe
operation of the appliance.
Isolate power supply before
opening and closing contacts T1,
T2A and T2B.
Master and Slave burners are
interlocked. If one burner does not
fire or proceeds to lockout, the
other burner will cease to function.
