It is simple as the Mysteryman says.
Use a simple diverter 3 port valve and away you go.
WBIB is optional for pump overrun, but this is the open vent model only.
We recommend this boiler for all open vent applications below 26kw. It has a number of advantages over the competition;
1. No compartment ventilation needed
2. Small size
3. Heavyweight unique heat exchanger, not thin steel like the Giannoni commonly used by competitors
4. No requirement for a 22mm inlet (as per Bosch)
5. Simple weather comp if a customer desires it
6. Pump overrun cable not mandatory
7. Multiple flue options inc chimney liners
8. 5 yr parts and labour
Disadvantages;
1. Flow switch
2. Flueing a bit flimsy
3. Condense trap difficult to clean without spilling contents at the annual service
4. Casing top retaining insert clips are usually found broken if the box has been transported upwards by the merchants.
