8. Using software, Select device 1 and open
“Service / Special operation” (Select devices 2
& 3 as you begin to commission further heat
engines).
9. Using software, select line 7145 “Controller stop
set point” and set it to 100%
10. Using software, select line 7143 “Controller stop
function” and set to “on”. The heat engine will
now run at 100% loading.
11. Once the heat engine has ignited a “
fl
ame”
symbol should be visible on the user display and
/ or a
fl
ame should be visible through the heat
engine sight window.
12. Allow
fi
ve minutes for the Heat engine to warm
up before checking the combustion.
13. The CO
2
fi
gure should be within the range 9.0%
to 9.3%. If adjustment is required, pull o
ff
the
black rubber cover from the Throttle Screw and
adjust. Screw clockwise to reduce CO
2
, anti-
clockwise to increase the CO
2
. (Fig. 5.3)
14. When the correct combustion readings are
achieved, replace the cover over the Throttle
Screw.
15. Press the DHW demand button to turn o
ff
the
appliance and when the burner has stopped
fi
ring remove the Gas Valve electrical connector
of the heat engine and then replace the
connector on the next to be tested.
16. Remove the gas analyser probe from the
fl
ue
elbow and replace the sample point plug.
17. Press the RESET button on the front of the
control panel.
18. Repeat procedures 6 – 17 until all heat engines
have been tested.
19. Finally: Switch o
ff
appliance power. Re
fi
t all gas
valve electrical connectors and ensure all sample
point plugs have been replaced into each
fl
ue
elbow.
NB. This appliance is optimised to provide Space
Heating and DHW in equal quantities. However,
if this appliance is used primarily for the supply
of DHW and has very little or no Space heating
demand, there is a small e
ffi
ciency bene
fi
t if the
circulation pump on each heat engine (see
fi
g 7.3) is
moved from speed 3 to speed 2

The casing is
fi
nished with a polyester coating and
will mark if abrasive cleaners are used. It should
be cleaned using standard non abrasive cleaning
products.
3.4 FINAL CHECKS

ANDOVER
When commissioning is satisfactorily completed the user
must be instructed on the use and operation of the appli-
ance and in particular detail:
- Hand over to the user the “User’s Instruction
Guide” as well as all other lterature relating to the
appliance.
- Explain the importance of air vents and the
fl
ue
outlet system, and that they should not be altered
or interferred with in any way.
- Explain to the user the importance of internal
water pressure and how to restore it to the correct
value.
- Explain and demonstate to the user the correct
function and adjustment of the temperature,
thermostats and radiators for the economic use of
the system.
- Remind the user that in order to comply to the
regulations in force the appliance has to be
inspected and serviced regularly as indicated by
the manufacturer.
Finally these instructions should be handed over to the
user.
3.5 FROST PROTECTION & LEGIONELLA

ROST
P
ROTECTION
The Heater is
fi
tted with automatic Frost Protection. Pro-
vided there is Mains and Gas, if the LLH sensor reads less
than 8°C a Heat Engine will
fi
re to bring the temperature
up to 16°C. NB
Other Frost protection levels can be set
according to customer requirements.

EGIONELLA
The Heater is provided with an Anti-Legionella pro-
gramme. It set by default to be o
ff
but can be set to be
started manually or periodically. Lines 1640 to 1647
control how, and when this function will operate.
