Pre-Installation

spray cans, primers, cleaners, paint and glue).

NOTICE:
Damage to appliance:
Extreme temperatures may cause damage to the heating system.
▶ Ensure the ambient temperature is above 0 °C and below 35 °C.
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.
▶ Install a frost thermostat and pipe thermostat connected in series, to
protect the system pipe work.
We recommend that the frost thermostat is sited in the coldest
unheated area in which pipe work is located and that it is set to call for
heat at 5 °C. The Pipe stat should be located on whichever pipe is
furthest from the heated area where warmer water will be drawn from
considering the direction of flow, and set to end the demand at 15 °C.
▶ 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 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, 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 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 for checking
and topping up.
