If You Smell Gas; Electrical Work; Installation And Maintenance; Danger To Life From Carbon Monoxide - Worcester Greenstar 4000 Installation And Maintenance Instructions Manual

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 Risk to life from carbon monoxide poisoning.
There is a risk to life from escaping flue gases
▶ Do not modify the flue gas system.
▶ Ensure that flue pipes and gaskets are undamaged.
If flue pipes are damaged or leaking:
▶ Turn off and isolate the appliance.
▶ Open windows and doors.
▶ If necessary, leave the building and warn your
neighbours.
▶ Prevent anyone from entering the building.
▶ Rectify any damage to the flue system immediately.
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.
