1.1 Welcome
These instructions are an integral part
of the boiler and must, to comply with
the current issue of the Gas Safety
(Installation and Use) Regulations, be left
with the user.
Ensure that the installer has fully
completed the Benchmark Checklist
located on the inside back pages of the
installation instructions supplied with
the product and that you have signed it
to say that you have received a full and
clear explanation of its operation. The
installer is legally required to complete a
commissioning checklist as a means of
complying with the appropriate Building
Regulations (England and Wales).
All installations must be notified to Local
Area Building Control either directly or
through a Competent Persons Scheme.
A Building Regulations Compliance
Certificate will then be issued to the
customer who should, on receipt, write the
Notification Number on the Benchmark
Checklist.
Read these instructions and follow them
carefully for the safe and economical use
of your boiler.
Do not forget to read the
chapters “Safety” and
“Guarantee” where you will find
important information for your
safety.

9 Fault Finding
In this section fault codes that are
displayed, which CAN be carried out by
the USER to restore appliance operation
(Corrective action: ...). Other fault codes
MUST be solved by a competent person
only.
Like all condensing boilers
it 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.
It is normal and not a fault
indication.
If any fault persists, and your appliance still
does not work, leave it switched off and
contact your competent person.
9.1 Electrical Supply Failure
The boiler will not work without an
electrical supply and normal operation
of the boiler should resume when the
electrical supply is restored.
If the boiler does not resume normal
operation, check the external controls.
It may be necessary to restart your
appliance.
• To restart the boiler, press the reset
button, see chapter "How to use your
appliance ►Overview".
9.2 Appliance fails to light
The LCD will display a flashing 'F' and
code number,
• To restart the boiler, press the reset
button, see chapter "How to use your
appliance ►Overview".

10 Appliance safety devices
10.1 Boiler Shutdown
The boiler software is designed to
recognise the potential for an overheat
lockout and will shutdown before this
happens.
• To restart the boiler, press the reset
button, see chapter "How to use your
appliance ►Overview".
If the boiler fails to resume normal
operation and all external controls are
calling for heat, then call your Installation/
Servicing company or Glow-worm service.
10.2 Protecting against frost
Appliance Protecion
In case of the risk of frost:
• Make sure that the electrical and gas
supply to the appliance is turned on.
• For an absence of several days, you
can leave the appliance to run normally.
The appliance has a built in frost
protection device that protects the boiler
from freezing. With the gas and electric
supplies ON and irrespective of any room
thermostat setting, the frost protection
device will operate the pump when the
temperature of the boiler water falls
below 8OC. A timer is used so that the
temperature can be checked periodically.
After 10 minutes the pump will be stopped
if the temperature is higher than 10OC or
has already reached 35OC. The burner
will activate if the boiler temperature
does not reach 10OC after 30 minutes or
at any time if the temperature drops to
5OC. The burner will switch off when the
temperature reaches 35OC.
The appliance always has frost protection
active when the power and gas supply are
on.
System Protection
The boiler alone cannot ensure that the
installation is protected against frost.
NOTE: Any other exposed areas of the
system should be protected by a separate
frost thermostat.
In case of prolonged absence, where
power to the dwelling and the boiler is
switched off, contact your Installation/
Servicing company or Glow-worm Service
to have the installation drained or to have
the heating circuit protected by adding an
anti-freeze specially designed for heating
systems.
CAUTION: Your domestic
water circuit (hot and cold) is
not protected by the boiler.
10.3 Condensate Drain Blockage
As a safety feature the boiler will stop
working if the condensate drain becomes
blocked. During freezing conditions this
may be due to the forming of ice in the
condense drain external to the house.
• Release an ice blockage by the use of
warm cloths on the pipe.
The boiler should then restart.
• Contact your Installation/Servicing
company or Glow-worm service if the
fault persists.
10.4 Safety Discharge Valve
The safety discharge valve and discharge
pipe is fitted to the boiler.
• If there is any discharge from the pipe,
switch off the boiler electrical supply,
then call your Installation/Servicing
company or Glow-worm service.

12 Tips for saving energy
Your installer will be able to give energy
saving advice about your system and its
controls.
For energy saving advice you can contact
the Energy Savings Trust for advice or
visit www.energysaving trust.org.uk who
offer simple effective advice about saving
energy.
Regular servicing of your boiler will help
maintain its efficiency - servicing once a
year is recommended
Turn your thermostat down. Reducing
your room temperature by 1°C could cut
your heating bills by up to 10 percent. Set
your heating and hot water at the time
controller to come on only when required
rather than all the time.
