H Danger to life from carbon monoxide
Carbon monoxide (CO) is a poisonous gas, which
arises during the incomplete combustion of fossil fuels
such as oil, gas or solid fuels.
Dangers arise, if carbon monoxide escapes from the
heating system due to a fault or a leak and collects
unnoticed in enclosed spaces.
You can neither see, taste nor smell carbon monoxide.
To avoid danger from carbon monoxide:
▶ Have the heating system inspected and serviced
regularly by an approved contractor.
▶ Use a CO detector, which gives an alarm in good
time if CO escapes.
▶ If you suspect a CO leak:
– Warn your neighbours and leave the building
immediately.
– Call an approved contractor.
– Have any defects rectified.
H Inspection, cleaning and maintenance
The user is responsible for ensuring the heating
system is safe and environmentally compatible.
Non-existent or improper inspection, cleaning and
maintenance may result in personal injury, including
danger to life or material damage.
We recommend that you enter into a contract covering
an annual inspection and responsive cleaning and
maintenance with an approved contractor.
▶ Have work carried out only by an approved
contractor.
▶ Have the appliance and heating system inspected
by an approved contractor at least once a year.
▶ Have any required cleaning or maintenance work
carried out immediately.
▶ Have any defects in the appliance and heating
system remedied immediately, independent of the
annual inspection.
H Fittings and modification
Only a competent engineer can remove the appliance
case and carry out any work, in accordance with the
relevant Installation Regulations.
Any misuse or unauthorised modifications to the
appliance, flue or associated accessories and heating
