Accessories to be connected:
- Expansion vessel (an option) precharged to
0.5 bar suitable for an installation up to 100 litres.
(For more than 100 litres provide for additional
expansion).
- Heating system safety pressure relief valve for
connecting to the waste water outlet via a funnel
and siphon trap.
- Condensate drainage siphon trap for connect-
ing via Ø 25 PVC pipe to the waste water outlet
via a funnel and siphon trap. When installing the
system, don’t forget to fill the siphon traps with
water before commissioning. These should be in-
spected twice a year.
-A circulating pump with an air vent. The silicon
tube from the purger should be slid inside the fun-
nel.
The heating flow and return pipes must be fitted with
stop valves so that work can be carried out on the
boiler if required without draining the installation.

The power delivered by the boiler depends on the
water flow rate through the exchanger. This can be
set to between 1200 and 2500 litres/hour according
to the installation’s rated power output.
To ensure that heat transfer operates correctly and
to avoid any risk of boiling, never use a flow rate of
less than 1200 litres/hour.
