Bleeding the CH Pump
Posted: Wed Nov 21, 2007 3:15 pm
When bleeding a Gundfoss pump (Chrome center screw) should the boiler be fired up and the pump running? The pump is fitted in the return pipe underneath a wall hung boiler.
The pump has two speeds which speed is the best to use??
Many Thanks for any advise.
