Installation & Servicing
INSTALLATION
The condensate trap provided within the hardware pack must
be connected to the condensate drain on the bottom of the
boiler and then connected to a drainage point, preferably
within the building.
The pipe size from the condensate trap is 25mm.
The routing of the drain must be made to allow a minimum fall
of 1 in 20 away from the boiler, throughout its length.
IMPORTANT. Any external runs must be kept to a minimum
and insulated. This is to avoid freezing in cold weather
causing blocking.
All pipework and fittings in the condensate drain system must
be made of plastic. No other materials may be used.
Ensure condensate trap is full of water before lighting.

Note. This appliance is NOT suitable for use
with a direct hot water cylinder.
Plastic plugs fitted into the open ends of the
flow and return pipes must be removed
before connecting the system pipework.

29 FROST PROTECTION
The boiler has built into its control system the facility to
protect the boiler only against freezing.
If the boiler flow temperature T
1
, falls below 7ºC the pump runs
without the boiler firing until the temperature exceeds 10ºC.
If the flow temperature falls below 3ºC the boiler will fire at
minimum rate until the temperature exceeds 10ºC.
Central heating systems fitted wholly inside the building
do not normally require frost protections as the building
acts as a 'storage heater' and can normally be left at least
24 hours without frost damage. However, if parts of the
pipework run outside the building or if the boiler will be left
off for more than a day or so, then a frost thermostat
should be wired into the system, see Frame 48.
