B2HA boiler (see page 9 for maximum water flow rate of
boiler).
The use of a low-loss header is strongly recommended if
the maximum water flow rate in the application concerned
exceeds the values shown in the applicable table on page
10, or if the system flow rates are unknown.
The low-loss header is available as accessory part.
See following pages for installation examples with a low-
loss header.
