CE LABEL
The appliance complies with the basic
requirements of the relevant European
directives.
Conformity has been substantiated by the
proper documents which, together with
the declaration of conformity, are filed
with the manufacturer.
FROST PROTECTION
The boiler has integrated frost protection.
The frost protection switches the boiler on at a CH flow
temperature of 7 °C and switches it off at a CH flow
temperature of 15 °C.
The central heating system is not protected against
frost.
If there is a risk of radiators or pipe sections
freezing up, we recommend setting the
pump over-run time to 24 hours.
See section 14.3, page 71.
PUMP TEST
If the boiler has not received a heat demand for
approximately 4 weeks, the pump will automatically
cycle for 10 seconds every 24 hours. This pump test is
first carried out for 24 hours when first switched back
on.
