Ferroli f30 bypass. Advice please

[tinbasher]

moved in to new house last week
Going to fit a Spirotech mb3
System dirty
Flushing etc first
Below the boiler there is a manual bypass
Ie tee from flow to return pipe .tee on return pipe
Gate valve in middle (closed)
Struggling to fit spirotech with the bypass there
Can I not just take trv off one radiator
To create a bypass
Pipe work from boiler goes through concrete floor
Any advice would be appreciated

All rads got trvs one side ?

 

[tinbasher]

Yes all radiators have them install

22mm from boiler through floor
8mm microbore up to rads

Change one to a lockshield no need for an auto bypass then
