H If you smell gas
A gas leak could potentially cause an explosion. If you
smell gas, observe the following rules:
▶ Prevent flames or sparks:
– Do not smoke, use a lighter or strike matches.
– Do not operate any electrical switches or unplug
any equipment.
– Do not use the telephone or ring doorbells.
▶ Turn off the gas at the meter or regulator.
▶ Open windows and doors.
▶ Warn your neighbours and leave the building.
▶ Prevent anyone from entering the building.
▶ Move well away from the building: call the National
Gas Emergency Service on 0800 111 999.
▶ L.P.G. boilers: Call the supplier's number on the
side of the gas tank.
H Danger to life from poisoning by flue gas
There is a danger to life from escaping flue gas.
▶ Never modify any parts through which flue gas is
routed.
If flues are damaged or leaking, or if you smell flue gas,
observe the following rules.
▶ Switch off the heat source.
▶ Open doors and windows
▶ Warn your neighbours and leave the building
immediately.
▶ Prevent third parties from entering the building.
▶ Notify an approved contractor.
▶ Have any defects rectified.
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 Combustion air/ambient air
The air in the installation location must be free of
flammable or chemically aggressive substances.
▶ Do not store or use any highly flammable or
explosive materials (paper, petrol, thinners, paints
etc.) within the vicinity of the heat source.
▶ Do not store or use any corrosive substances
(solvents, adhesives, chlorinated cleaning agents,
etc.) within the vicinity of the heat source.
H Inspection and maintenance
If there is a lack of cleaning, inspection or
maintenance, or if these are carried out incorrectly,
this may result in material damage and/or personal
injury, including possible loss of life.
▶ Have work carried out only by an approved
contractor.
▶ Have any defects rectified immediately.
▶ Have the heating system inspected once a year by
an approved contractor, and have any required
maintenance or cleaning work carried out.
▶ Have the heat source cleaned at least every two
years.
▶ We recommend that you enter into a contract
covering an annual inspection and needs-based
maintenance with an approved contractor.
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
system will invalidate the guarantee.
▶ Do not modify the appliance or flue system in any
way.
Worcester accepts no liability arising from any such
actions. This does not affect your statutory rights.
