Pressure Relief Safety Valve
A pressure relief safety valve and discharge pipe is fitted to the
boiler. This valve must not be touched. Should there be any
discharge from the pipe, isolate the boiler electrical supply and
call your installer or Halstead Boilers using the telephone
number on the front cover of this booklet.
Condensate Drain
The condensate drain, see section 9.2, must not be modified or
blocked.
Cleaning
This appliance contains metal parts and care should be taken
when handling and cleaning with particular regard to edges.
The boiler casing can be cleaned using a mild liquid detergent
with a damp cloth, then a dry cloth to polish.
Do not use any form of abrasive or solvent cleaner as you may
damage the paintwork.
Pluming from flue terminal
Like all condensing boilers this appliance will produce a plume
of condensation from the flue terminal in cool weather. This is
due to the high efficiency and hence low flue gas temperature
of the boiler. It is normal and not a fault indication.
Replacement Parts
If replacement parts are required contact Halstead Boilers
using the telephone number on the front cover of this booklet.
Please quote the name of the appliance this infomation will be
on the front of the appliance.
To Operate the Boiler
1. Check that all five isolating valves are open, see diagram 8.1.
2. A sealed pressurised system must be filled and pressurised
by a competent person.
3. Check that the electrical supply to the boiler is ON at the
external isolator.
Only operate the boiler when you are sure that the system has
been filled and pressurised. Check this by looking at the
pressure reading on the digital display, which should read
1.0bar, see diagram 1. The digital display gives a pressure
reading when there is no demand or when the appliance is in the
domestic hot water mode.
4. Open a hot water tap, check that water flows, then close it.
5. If you are in any doubt about the boiler being filled with water
contact your installer or Halstead Boilers using the telephone
number on the front cover of this booklet.
6. Set any remote controls as required.
7. Turn the mains reset on/off switch to the ON position (I), see
diagram 1. The control light will illuminate (green) indicating the
boiler is lit.
User Controls
The temperature of the domestic hot water and the central
heating water can be set on the control knobs on the controls
fascia, see diagram 1.
Mains Reset Switch
0: Off.
I: On.
A fault is indicated by a RED flashing light on the control light
and flash fault code on digital display.
To reset:
Turn mains reset switch to O anti-clockwise.
Wait five seconds.
Turn mains reset switch to I clockwise.
Central Heating Temperature Control:
0: Temperature control is Off.
I: Temperature control is On. To adjust the temperature turn the
control to the desired setting between I ‘Min’ and
‘Max’.
‘Max’
is approximately 82
°
C (180
°
F).
Hot Water Temperature Control:
0: Hot water is Off.
Turn selector between 1 and MAX to adjust water temperature
between 40
°
C and 60
°
C.
The
ECO
setting, water temperature 55
°
C, is the recommended
optimum position for constant use.
Digital Display
If the digital display shows pressure less than 0.7bar, re-
pressurise the system to 1bar. If the system repeatedly looses
pressure, YOU MUST CONTACT YOUR INSTALLER OR
HALSTEAD BOILERS USING THE TELEPHONE NUMBER
ON THE FRONT COVER OF THIS BOOKLET.
Please note: The digital display will only indicate the system
pressure when there is no demand for heat.
To Turn the Boiler Off
There is a mains/reset switch on the right hand side of the
controls fascia, which will isolate the boiler. However, it is
preferable to leave the electrical supply on whenever possible
to permit operation of the built-in frost protection (see 'Protection
Against Freezing') and daily pump and valve exercise.
To turn off the central heating use the room thermostat or clock/
timer.
To turn off the domestic hot water turn the domestic hot water
knob to the minimum setting.
For holiday mode turn both of the temperature knobs to the
minimum setting.
To turn off the boiler for servicing, isolate it from the electrical
supply. To turn it on again follow the instructions given in ‘To
Operate the Boiler’.
