By pressing the ‘INFO button three times, the Boiler Sequence Description Operating Sequence can be
witnessed, indicated by Large Number numeric notation on the display.
Having reviewed the Operating Sequence, press the ‘MODE’ button once to return to the standard screen.
The controller will also automatically return to the standard screen after approximately  seconds.
The adjacent table details the numeric notation of the ignition sequence.

The following procedure MUST be followed to ensure that damage does not occur to the boiler on
the initial  ring.
a) Ensure that the gas supply has been purged, and if so turn the gas isolation valve to the OPEN position.
b) Ensure that the electrical supply has been tested, and if so, turn ON.
c) Check that all pumps, both internal boiler pump and external pumps, are correctly bleed of air, and that
their impellors are free to turn.
d) Switch the boiler ON/OFF switch to the ON position. The boiler controller will then run though the prelimi-
nary safety checks. Check and record the LMU and Display software versions, as previously detailed.
e) Once the safety checks have been proven, the controller will then re-
turn to the STANDBY setting. Set the controller to the COMMISSIONING
HIGH mode, by pressing the ‘RADIATOR’ and TAP’ buttons together for
a minimum of ten seconds.
Arrows will appear next to the ‘SPANNER and ‘ENGINEER symbols on
the ‘Right-Hand’ side of the LCD display.
If an arrow appears next to the ‘ENGINNER’ symbol ONLY, then the
boiler will be at 100% output Only. Repress the ‘RADIATOR’ and ‘TAP’
buttons, holding for a longer period of time until the arrows appear
next tothe ‘SPANNER’ and ‘ENGINNER’ symbols.
f) With the arrows adjacent to the ‘SPANNER’ and ‘ENGINEER symbols, the boiler will operate under the
dictates of the ‘+’ and ‘-‘ buttons, and the
and buttons. The Output of the boiler will be displayed on
the LCD display as a percentage of the modulation output. (i.e.  = Max Burner Output,  = Min
Burner Output.
g) The burner will now operate at the indicated output on the LCD display, until the boiler temperature
reaches °C, at which point the burner will turn o . To monitor the boiler  ow temperature during the
burner commissioning, press the ‘INFO button once. Press the ‘MODE’ button once, to return to the Com-
missioning Output screen. Pressing the ‘MODE’ button once, to exit from the Commissioning mode.
h) Due to the Design of the Gas Valve, the HIGH FIRE setting should be made  rst, as this will have a marked ef-
fect on the LOW FIRE setting. A . mm Allen key will be required to undertake the necessary adjustments.
i) Remove the Flue Gas Sampling Test Point Cap and insert a  ue
gas analyzer into the Test Point. The stop on the analyzer probe
should be set to a depth of - mm . See  g .a.
j) If the burner is not already at  Output, use the ‘+‘ or
but-
tons to increase the burner output to , take a sample and
note the CO level.
k) Using the ‘-‘ or
buttons to decrease the burner output to ,
take a sample and note the CO level.
l) Check the CO levels recorded against those listed in the adja-
cent table. If the CO levels are not as listed, adjustments to the
gas valve ‘High Fire and/or ‘Low Fire will be required. See  g
.b for adjustment locations.
m) To adjust the HIGH FIRE setting, use the ‘+‘ or
buttons to set
the controller to  burner output. After the burner has sta-
bilized, adjustments can be made to ‘High Fire adjuster on the
gas valve (clockwise to decrease, anti-clockwise to increase the
CO). After each adjustment, let the burner stabilize for a minute,
then check the levels again. See Fig .b. Continue until the
CO levels are as listed in the adjacent table.
