ROUTINE SERVICING
To ensure continued safe and efficient operation of the appliance it is recommended
that it is checked and serviced as necessary at re_gular intervals. The frequency of
servicing will depend upon the particular installation conditions and usage but in
general once a year should be regarded as a minimum even if only occasional usage
nas occurred.
It is the law that any service work MUST be carried out by a competent Gas Safe
Registered Engineer.
SAFETY
It is essential that these instructions are strictly followed for the safe and economical
operation of this appliance. The appliance is a fan-assisted room sealed gas boiler and
therefore the flue terminal MUST NOT BE OBSTRUCTED under any circumstances. If
it is damaged, turn off the appliance and consult your installer, or service engineer. If it
is known or suspected that a fault exists on the appliance it MUST NOT be used until
the fault has been rectified by a competent Gas Safe Registered Engineer.
THERMOSTATS/TIMERS/PROGRAMMERS
This appliance may be fitted with one of the above devices to control the central heating
function in the home. These devices may override the controls of the boiler. For
example: the boiler will not fire in CH mode when a room thermostat senses its set point
temperature has been reached or a time clock is outside of the time zone selected for
CH to operate.
If the boiler is installed in a Caravan Holiday Home, refer to the user manual for the
home, for the positions of all drain plugs.
Note: There are no drain plugs fitted to the actual boiler.
-Leave all taps and plugs open until the boiler is next needed for service. This will allow
any residual water to continue to drain.
NOTES ON FROST PROTECTION
The heating circuit and radiators should contain the correct level of antifreeze to
prevent damage during freezing conditions and should not be drained down.
Opening the hot and cold water drain cocks should be sufficient to drain all the
water from the boiler.
However in some installations it rna}! be necessary to blow through the system with
air to ensure the water has drained. The filling loop valve below the boiler may also
be used as an extra drain point.
ALL FROST DAMAGE IS OUTSIDE OF THE WARRANTY
