The Benchmark initiative is a code of practice to encourage the

installer at the time of installation. It confirms that the boiler has
been installed and commissioned according to the manufacturers
instructions.
In Eire the declaration found in IS 813 must be completed.
Without completion of the checklist and/or declaration,
manufacturers may refuse to respond to a call-out request. It is
important that the checklist and/or declaration are fully completed by
your installer.
GENERAL DESCRIPTION
(See Fig.1.)
The WORCESTER 26CDi Xtra is a condensing, combined domestic hot water
and central heating appliance. It consists of a gas fired boiler with a secondary, high
efficient heat exchanger, having a varying output of between 6.7 kW and 26 kW. A
water to water heat exchanger to provide domestic hot water via the boiler,
circulating pump and water diverting valve. All the necessary controls to provide
mains fed domestic hot water and central heating.
The appliances are supplied as standard with a manual operating
switch. Alternatively a facia mounted programmer may have been fitted.
The appliance can operate in one of two modes. Hot water only or hot water
and central heating.
PLUMING: Because the appliance operates at high efficiency a white
plume of condensate will be emitted from the flue terminal which is fitted
outside the dwelling. The pluming will be more noticeable during cooler weather
and will occur every time the appliance is used. 3
