Overheat Safety Cutoff
If the cutoff operates on any other occasion than an electrical
failure, press the reset button as stated in “Electrical Supply
Failure”.
If the boiler fails to relight contact your installation/servicing
company.
To Turn the Boiler On
Sealed Water Systems.
CAUTION A sealed water system must be filled and pressurised
by a competent person.
Only light the boiler when you are sure that the system and
boiler have been filled and pressurised.
The pressure gauge should show at least 0.7bar, anything less
than this figure could indicate a leak and you MUST contact your
installation/servicing company.
If there is any doubt about the boiler and system being full of
water consult your installation/servicing company.
All Systems
Turn the electrical supply on to the boiler and check that any
remote controls are set to your requirements (refer to
manufacturer’s instructions for these items).
On demand, the orange light will come on.
Turn the left hand switch to “high” flame.
Turn the control thermostat knob, at the right, clockwise to any
position between “MIN” and “MAX., see diagram 1. The
maximum setting is about 82
o C (180 o F).
The boiler will not light between “O” and “MIN”.
The boiler lighting operation is now automatic as follows:
The fan operates, followed by an ignition spark until the burner
lights on low flame after a short period it will go to high flame and
the green light will come on.
The burner will remain alight until switched off by the control
thermostat or other remote control.
If the control thermostat is turned “Off”, by hand, wait at least 30
seconds before turning on again.
When the boiler thermostat is satisfied the burner and green
light will go out.
When the system controls are satisfied the burner, orange and
green lights will go out.
The automatic lighting sequence will operate again when heat
is required.
The “high/low” switch should be set to “high” for winter use, but
when domestic hot water only is required in the summer it can
be turned to “low”.
If no light comes on you should contact your installation/
servicing company, to check the controls, although the system
may be working.
To Turn the Boiler Off
For short periods, turn thermostat control knob anti-clockwise
until “O” is against the setting point. To relight the main burner,
turn the thermostat knob clockwise to any setting between ”MIN”
and “MAX”.
For longer periods, turn the thermostat control knob anti-
clockwise until “O” is against the setting point and switch off the
electrical supply to the boiler.
To relight follow the sequence given above.
Note: If the burner goes out for any reason, wait 30 seconds
before relighting.
Condensation Pluming
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.
