The Halstead Best db 30,40,50,60 and 80 are wall mounted, fan assisted
balanced flue, natural gas boilers incorporating a cast iron heat exchanger. The
appliance has the benefit of automatic direct burner ignition and electronic
temperature control. It features an attractive white enamelled case with a
removeable front panel, which when removed enables the appliance to be fitted
within a standard kitchen wall unit. (Refer to Installation Instructions).

LIGHTING THE BOILER
Ensure that all secondary controls (timer, room thermostat and cylinder
thermostat where fitted) are turned to maximum. Turn on the electrical supply
and check the pump is working and is circulating water through the system.
If fitted, remove the front boiler panel by lifting it approximately 10mm then
moving it away from the boiler.
Turn the boiler thermostat fully clockwise to its maximum setting. After a few
seconds the boiler will light. The burner flame can be viewed through the viewing
glass in the front of the sealed inner case.
Turn the boiler thermostat and all the external controls to their required setting.
If the boiler fails to light, and the ignition reset neon illuminates, wait 15 seconds
and reset the ignition by depressing the reset button once. Ensure all secondary
controls are turned to maximum before attempting to reset ignition.
Refit the front panel.

TO TURN OFF THE BOILER
If you wish to switch off for short periods, turn the boiler thermostat knob fully
anti-clockwise to the position marked 'O'. To restart, turn the knob clockwise to
the required setting. If you wish to switch off for longer periods, turn the boiler
thermostat knob fully anti-clockwise to the position marked 'O' and isolate the
boiler and system from the electrical supply. Refer to section 5 for frost
protection.

ELECTRICAL FAILURE
In the event of electrical failure the boiler will go out.
Normal operation of the boiler should continue when the supply is restored.
However, should the boiler fail to re-light, check the warning neons on the boiler
control panel.
If the ignition neon is illuminated allow 15 seconds then press the reset button to
restart the boiler.
If the ignition and over-heat neons are illuminated allow the boiler to cool, switch
the electrical supply off then on again, the over-heat neon will now be out, the
ignition reset button can now be pressed to restart the boiler.
Should the boiler fail to light and the over-heat neon become illuminated again
the boiler has not been allowed to cool sufficiently.
5
FROST PROTECTION
If the boiler is turned off during severe conditions, it is recommended that the
whole heating system be drained. If in doubt ask your Service Engineer.
If a frost thermostat is fitted, leave the boiler with the boiler thermostat turned to
position 1, and turn off the time control switch only.

OVER-HEAT NEON ILLUMINATION
When the over-heat neon is illuminated it shows that an over-heat situation has
occurred.
The boiler may be restarted, provided it has been allowed to cool, by pressing
the ignition reset.
The boiler may continue to run without further problems, although the over-heat
neon will still be illuminated. Ensure all secondary controls are turned to
maximum before attempting to reset the boiler.
A Service Engineer should be called to check the BOILER AND SYSTEM for any
possible faults.
The over-heat neon will stay illuminated providing the permanent electrical
supply to the boiler is maintained. It may be turned off by switching off the
electrical supply to the boiler. When the electrical supply is switched on again the
over-heat neon will be off.
