GAS APPLIANCE
Gas safety (Installation and Use) regulations
In the interests of your safety and that of others,
it is a legal requirement that all gas appliances
are installed and correctly maintained by a
competent person and in accordance with the
latest regulations.
ELECTRICAL SUPPLY
Please ensure that this appliance has been
properly connected to the electrical supply by
means of a double pole isolator or un-switched
socket and that the correct size of fuse – 3 amp
– has been fitted.
Warning: this appliance must be earthed!
EXPLANATION OF CONTROLS
The Vokera Compact has been designed for
simplicity of use, as a result there are only two
controls – the mode selector switch & the time
clock – that can be accessed by the user.
MODE SELECTOR SWITCH AT:
OFF: when the mode selector switch is in the
‘OFF’ position, the appliance will not function for
hot water or heating. However the appliance will
still operate in frost protection mode, and if unused
for a period of 24 hours, will momentarily activate
the pump to prevent seizure due to non-use.
NOTE
The appliance must have an electrical supply at
all times for the frost protection and anti-seize
modes to operate.
HOT WATER ONLY “
”: when the mode
selector switch is in the ‘HOT WATER ONLY’
position, the appliance will operate as above.
However when a hot water outlet is opened the
appliance will operate to provide hot water until
the demand for hot water has been satisfied.
NOTE
The appliance delivers a fixed maximum flow rate
of hot water, therefore if a hot water outlet is
turned on full, it is most likely that you will be
unable to obtain hot water from another outlet at
the same time.

1.3.4
1.4
1.4.1
1.4.2
”: when
HEATING AND HOT WATER “
the mode selector switch is in the ‘HEATING AND
HOT WATER’ position the appliance will operate
as above. However should the time clock be
switched on automatically or manually, the
appliance will operate to provide heat to the central
heating circuit until the demand has been satisfied.
NOTE
If a room thermostat is fitted it must be calling for
heat before the appliance will operate.
TIME CLOCK
The Vokera Compact is supplied with a built-in,
24-hour, time clock that can be set to operate the
appliance for central heating. However it may be
that your installer has fitted an external time clock
(usually because of the location of the appliance
i.e. loft, basement, outhouse, etc.) if so, please
disregard the following instructions and refer to
those supplied with the external time clock.
EXPLANATION OF FEATURES
Although the Vokera Compact has been designed
for simplicity of use, it utilises the latest in boiler
technology, enabling a host of functions to be
carried out simultaneously.
FROST PROTECTION MODE
Should the temperature of the appliance fall to 7
°C. the pump will be activated for a period of 15
minutes or until the temperature of the appliance
rises to 10 °C. This will be repeated every two
hours. Should the temperature of the appliance
fall to 5 °C. the burner will ignite until the appliance
temperature rises to 30 °C.
AUTOMATIC HEATING REGULATION
The boiler will automatically adjust its output
temperature to suit site conditions. However,
Setting the time
The time of day can be set by grasping the outer edge of
the black dial and turning it in a clockwise direction until
the correct time is in line with the white pointer.
Off’
Auto
On
Setting the ‘switching times’
The ‘ON’ periods are set by sliding the black tappets,
adjacent to the time periods required, to the outer edge
of the dial.
The tappets that remain at the centre of the dial will be the
‘OFF’ periods.
The smallest switching time (ON or OFF) is 15 minutes.
To select ‘Auto’ mode move the selector switch in central
position.
To select ‘On’ mode move the selector switch in the
bottom position.

of 24 hours, the pump will be activated for a few
seconds to prevent seizure.
APPLIANCE STATUS INDICATORS

a fault (see below).
GUARANTEE REGISTRATION CARD
Please take the time to fill out your guarantee
HOW TO...
2.1
2.2
USE THE APPLIANCE FOR THE FIRST TIME
Before switching the appliance on please
familiarise yourself on how to isolate the appliance
from the electricity, gas, and water supplies. If in
doubt contact your installer.
USE THE MODE SELECTOR SWITCH
Turn the mode selector switch to the OFF position,
switch on the electrical supply to the appliance.
The green LED should be illuminated, you may
now select either HOT WATER ONLY or HEATING AND HOT WATER.
2.2.1
OBTAIN HOT WATER
By turning on a hot water outlet (tap) the boiler will
fire to deliver hot water.
The appliance will have been commissioned by
your installer to deliver hot water at both a
reasonable temperature and flow rate, should
you wish to increase the temperature of the hot
water simply reduce the flow of water as it comes
out of the tap. Please consult your installer for
further advice if required.
2.2.2
OBTAIN CENTRAL HEATING
When the time clock is in an ‘on’ position, and
the room thermostat – if fitted – is calling for heat,
the boiler will fire to provide central heating.
2.3

RE-PRESSURING THE SYSTEM
The system will need re-pressurising if the red
LED is illuminated. Locate the filling valve and if
necessary connect the loop (fig. 3) slowly open
the valve until you hear the water entering the
appliance. The red LED will go out first. Go on
with re-pressuring until the pressure shown on
the manometer is between 1 & 1.5 bar (fig. 4). The
appliance must not be operated until the system
has been re-pressurised. If in doubt contact your
installer.
SHUT DOWN THE SYSTEM FOR SHORT
PERIODS
The system can be shut down for short periods by
simply turning the mode selector to the OFF
position. It is also advisable to turn off the main
water supply to the house.

gas should be turned off at the meter and the
main water supply should be turned off at the
stopcock. If necessary contact your installer for
further advice.
