Site preparation/portability
Greenstar Highflow CDi appliances are supplied with a 
floor mounted pre-plumbing jig. The jig enables all gas and 
water services to be pre-plumbed and tested prior to fitting 
the boiler.
For ease of installation the appliance has a roll-in boiler tray 
which allows it to be rolled into place once the connections 
have been made.
