USER INSTRUCTIONS

User Data
All user controls are situated on the front panel of the
boiler, there are no user controls inside the boiler
casing. The following instructions assume that the
boiler has been commissioned, and that the system is
filled with water and has been fully vented.
Setting Up
•Before switching on any electrical supplies to the
boiler ensure that the combined temperature and
pressure gauge reads at least 1 bar and the control
thermostat is set to the desired temperature.
•If an internal time clock is fitted ensure that this is
switched on (see “Optional Internal Time Clock”)
and if any other auxiliary controls are fitted e.g.
programmer, room thermostats, cylinder thermostats
etc, consult appropriate manufacturers' instructions
to switch these on.
•Switch on any local means of isolation to boiler.
•Switch the boiler on using the ON/OFF switch (the
red neon light on the switch should now glow).
•Turn on both power level switches - after a short
period of time the boiler temperature should start
to rise, indicated by the combined temperature
and pressure gauge. If the boiler fails to operate,
the overheat safety thermostat should be checked.
Access to the thermostat reset button is obtained
by unscrewing (anti-clockwise) the domed button
cover on the front panel (a screwdriver is not
required).The reset button can then be seen - press
the button, a click should be heard and the button
is reset. If no click was heard the device is not at
fault and further investigation is required by a
suitably qualified engineer.
•The internal clock or external programmer can
now be set to allow on/off periods as desired.The
ON/OFF switch and 2 power level switches should
be left in the ON position during normal use.
NOTE : the power level switches will automatically
switch on and off during normal boiler operation,
depending on boiler temperature.
•If the boiler is not in regular daily use during cold
periods, it is recommended that it be fitted with a
frost sensing thermostat to override the timeclock
and prevent the system from freezing.
•As with most boilers and heating appliances the
casing and pipework can get hot during normal
running so the boiler must not be covered and the
surrounding area must be kept clear.
Optional Internal Timeclock
•This operates on a 24-hour sequence. Around
the outside of the clock there are a number of
white tabs - these allow 15 minute switching
times. To set a boiler cycle simply push outwards
the number of tabs required for your heating
period.
Remember : tab OUT = BOILER ON
tab IN = BOILER OFF
The time of day is marked by an arrow on the
inner part of the clock - set the outer time to
coincide with this arrow.
On the centre part of the clock there is a switch.
This has three positions :
•Switch down - timeclock off
•Switch middle - timeclock timed (normal position)
•Switch up - timeclock on constant.
