NOTICE
Damage to system:
The heating system pipe work can be damaged by frost if installed in an
internal unheated area, such as a loft, basement or garage.
The appliance internal frost protection only monitors the system water
temperature within the appliance to provide protection for the
appliance.
▶ System frost protection can be achieved when using either Worcester
weather-compensating controls or via a hard-wired thermostat when
using external 230v controls (refer to figure 58, page 43).
▶ The system pipe work in the internal unheated area should be
insulated.
▶ If the appliance is to be shut down for an extended period, drain the
central heating system.
The appliance must be installed where:
▶ The area is well lit, allowing users to clearly see the appliance to carry
out any work or checks.
▶ An engineer can gain clear and safe access to work on the product or
component, including making adequate provision for visual
inspection of flues in voids.
▶ The homeowner can gain clear and safe access to the controls or to
check, top up or reset the appliance.
▶ Roof space installations must fully conform to BS 5410 part 1: roof
space installations.
▶ Products in roof spaces must have permanent fixed lighting, a
permanent fixed retractable ladder and a fixed floor area sufficient to
allow access for normal use and servicing around the product and
between the product and the access hatch.
We would also recommend that a remote pressure gauge and filling
loop are sited where the customer can gain easy access to assist with
checking and topping up.
