Air supply
The Worcester Greenstar FS CDi Regular is a room sealed
appliance; the room in which it is installed does not
therefore require a purpose provided combustion air vent.
Natural gas supply
The appliances when on full output demand will require up
to 3.27m
3
/h (FS 30CDi) or 4.4m
3
/h (FS 42CDi) of gas. The
gas meter and supply pipes must be capable of supplying
this quantity of gas in addition to the demand from any
other appliance being served. Under no circumstances
should the size of the gas supply pipe be less than that of
the appliance inlet connection (22mm diameter). The meter
outlet governor should be capable of ensuring a dynamic
nominal pressure of 20mbar (8in wg) at the appliance.
Particular consideration should be given to the resistance
to gas flow created by elbows, bends etc. Pipework should
be sized to overcome this resistance, and details of this are
given in the following table.
Liquid Petroleum Gas (LPG) supply
The Greenstar FS CDi Regular appliance is available in an
LPG version. The appliance, when on demand at full output
will require 2.3kg/h for the FS 30CDi Regular and 3.3kg/h
for the FS 42CDi Regular.
The gas tank or bottles must be capable of supplying this
quantity of gas at a nominal pressure of 37mbar (14.8in wg)
at the appliance. The table below shows the LPG discharge
through varying lengths of pipe and the resistance to flow
created by elbows, bends etc. Pipework should be sized to
overcome this resistance.
Electricity supply
A 3 amp fused three pin plug and unswitched shuttered
socket outlet (both complying with BS 1363) or preferably a
double pole isolator with a contact separation of 3mm in all
poles supplying the appliance should be used.
The appliance electrical circuits are also protected by an
internal 2.5 amp fuse. The appliance must be earthed.
