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.
