GETTING STARTED
2.1
BEFORE SWITCHING ON
Before switching the appliance on please familiar-
ise yourself with:
●
how to isolate the appliance from the gas,
water, and electricity supplies
●
how to check and top-up - if necessary - the
system water pressure
●
the time clock or programmer
●
any external thermostats and their functions
●
the appliance controls.
2.2
APPLIANCE CONTROLS (see fig. 1)
The appliance controls are concealed behind the
front flap. To gain access to the controls simply lift
upward to engage the holding clip.
The appliance has a mode switch, variable ther-
mostat, system pressure gauge and an aperture
for an integral clock or programmer. The mode
switch has three positions:
●
Reset
●
Off
●
On
The variable thermostat allows you to set the
temperature of the water to your radiators and hot
water cylinder (not the hot water to your taps!)
between 40ºC (min) and 80ºC (max).
The pressure gauge shows the current pressure
of the system, the gauge should be set between
1 and 1.5 BAR. When the appliance is operating
the gauge may rise or fall slightly, this is quite
normal. The minimum permissible level for the
safe and efficient operation of the appliance is 0.5
bar. Should the pressure fall below 0.5 bar, the
boiler shuts off automatically.
Depending on the type of controls specified by
your installer you may have an integral Vokera
time clock or programmer fitted to the appliance,
if so, instructions can be found on pages 6-10. If
an external time clock or programmer has been
fitted, please refer to the instructions supplied
with such.
2.3
LIGHTING THE BOILER
Ensure the gas and electrical supply to the boiler
are turned on.
Turn the mode switch to the ‘on’ position. Refer to
the particular instructions for the type of program-
mer or time clock fitted and ensure there is a
demand for heating and/or hot water. If there is a
room thermostat and/or hot water cylinder ther-
mostat you should ensure these are also calling
for heat.
When there is a demand for heating and/or hot
water via the above controls the boiler will go
through an ignition sequence, whereby the burner
will light.
If the appliance fails to ignite during the ignition
sequence, allow a period of two minutes before
re-setting.
To adjust the output temperature of the appliance
turn the thermostat knob clockwise to increase or
anti-clockwise to decrease.
When the appliance reaches the set temperature,
the burner will go off for minimum period of ap-
proximately 3 minutes.
When the programmer/time clock or external ther-
mostats heating request has been satisfied, the
appliance will switch off automatically.
