1.6. WArNINGS
(a) Gas Leak or Fault
If a gas leak or fault exists or is suspected, turn the boiler mains electricity
supply off and turn off the gas supply at the meter. Consult your local gas
company or your local installation/servicing company.
(b) Clearances
If fixtures are positioned close to the boiler, space must be left as shown in
figure 4.3, section 4.4. Enough space must also be left in the front of the boiler
to allow for servicing.
(c) Sheet Metal Parts
This boiler contains metal parts (Case & components) and therefore care should
be taken when handling and cleaning, with particular regard to edges.
(d) Sealed Components
This boiler uses a fully premix burner with an air/gas ratio controller therefore
the burner input i.e. CO and CO settings and the burner off set pressure are
factory set and sealed and require no onsite adjustments during installation
or routine servicing.
Under no circumstances should the user should interfere with the sealed
components as this could result in a potentially dangerous situations arising. If
sealed components in the appliance are replaced and/or re-commissioned in
the field then these must be done strictly in accordance with manufacturer's
instructions and these components must be re-sealed.

1.9 PrOTEcTION AGAINST FrEEZING
(a) The boiler has a built in frost protection
programme as long as the electricity and
gas are left switched on. The boiler controller
operates the burner and the system pump
when the temperature inside the boiler falls
below 5ºC.
(b) Any other exposed areas of the heating and
hot water system should be protected as
normal by a separate frost thermostat / pipe
thermostat
(c) If the mains electricity and gas supplies to
the boiler system are to be turned off for
any long periods during severe weather,
it is recommended that the whole system
including the boiler should be drained to
avoid risk of freezing. In this case ensure that
the immersion heater in the cylinder (if fitted)
is also switched off.
(d) Contact your installation/service company as
draining, refilling and pressurising of a sealed
heating system MUST be carried out by a
competent person.
(e) As a safety feature, the boiler will stop working
if the condensate drain becomes blocked.
During freezing conditions this may be due
to ice forming in the condensate drain if this
has been installed external to the house. Ice
blockage should be released by use of warm
cloths on the pipe. Contact your installation/
service company if the fault persists.
1.10 BOILEr INSTALLATION IN A
cOMPArTMENT Or cuPBOArD

cupboard, it does not require ventilation openings.

incorrect fitting may result in incorrect operation
or failure to operate at all.
1.12 cONDENSATE DrAIN
The condensate drain must not be modified or
blocked. See section 4.4 (e) for further details.
