BURNER LOCK-OUT
If the burner fails to light, it will go to
lock-out. If this occurs, wait about one
minute then remove the front panel and
press illuminated reset button to start
burner.
In the event of the burner not firing
wait a further minute and then press the
reset button again. If the burner still
fails to start, switch off the electrical
supply to the boiler.
WARNING -
DO NOT ATTEMPT TO START
BURNER MORE THAN TWICE
(See Simple Fault Finding before
contacting your Service Engineer).
SYSTEMS CONTROLS
ROOM THERMOSTAT
The room thermostat should not be
positioned near a source of heat such as
a radiator or exposed to the sun as this
will cause the central heating to switch
off before the room is up to tempera-
ture. Follow the manufacturer’s
instructions for best siting position for
the thermostat.
TIME-SWITCH/PROGRAMMER
When choosing the operating times for
your boiler, it is useful to remember
that central heating usually takes
between half an hour to an hour before
it becomes effective.
It is suggested that the Time Switch/
Programmer is set to bring on the heating
about an hour before heating is required.
It is also worth noting that the heating
system will usually remain effective for
up to half an hour after boiler shutdown.
The timer can therefore be switched
off earlier as an economy measure.

TRIANCO BOILER

Your Trianco boiler has been designed
and constructed to give years of trouble
free service and these instructions are
provided to assist you in obtaining the
best performance with the least trouble
and cost.
The boiler is fully automatic in operation
and requires little attention other than
the setting of the thermostat and any
system controls such as a room thermo-
stat and time-switch.
TO FIRE THE BOILER
Before firing the boiler, ensure the system
is full of water, there is sufficient oil in
the storage tank and all valves are open.
Check that the Timeswitch /
Programmer (if fitted) is ON and the
room thermostat is calling for heat.
Set the boiler thermostat to the
desired temperature.
Switch on the electrical supply to
the boiler and the burner should
fire after a few seconds of fan pre-
purge.
Set the Time-switch/Programmer
(if fitted) to the times and pro-
gramme required.
The boiler will now operate auto-
matically, cutting in and out accord-
ing to the heat demand.
TO STOP THE BURNER
The burner may be stopped by turning
the Boiler Control Thermostat fully
anti-clockwise to the OFF position ‘O’
If the boiler is to be off for a long time,
it is recommended that the mains sup-
ply to the boiler is switched off or the
Time-switch/Programmer (if fitted) is
switched to the OFF position.
BOILER CONTROL
THERMOSTAT
The boiler control thermostat enables
you to select the temperature of the
water leaving the boiler. It is calibrated
between High and Low in five interme-
diate settings, corresponding to a tem-
perature range of 82OC (high) to 55OC
(low).
Set the temperature by turning the knob
to the required temperature. However,
the installer should take into consideration
that the return water temperature
must not drop below 56OC when the
appliance is up to full operating temper-
ature.
The thermostat is switched off when
the knob is turned fully anti-clockwise
with pointer opposite ‘O’
HIGH LIMIT THERMOSTAT
(Hand Reset)
The high limit thermostat is factory set
and requires no adjustment. Should the
boiler thermostat malfunction, the limit
thermostat will take over and shut down
the boiler.
If the limit thermostat operates
frequently, consult your Service
Engineer as there may be a fault in
the system.
To reset the limit thermostat, remove
the front panel and push in button.
Note: The limit thermostat can only be
reset when the water temperature has
dropped at least 20OC.
