BOILER CONNECTIONS (
)
The boilers have 5 water connections:
2 x Rp1 (1 in BSP internal) return connections.
2 x Rp1 (1 in BSP internal) flow connections.
1 x Rp3/4 (3/4 in BSP internal) flow connection.
The 1 x Rp3/4 (3/4 in BSP internal) flow connection is for use when the pump is fitted inside the
outer case. For other installations this connection must be plugged. THE WATER SPREADER
MUST BE FITTED TO THE PUMPED RETURN CONNECTION ON ALL INSTALLATIONS. THE
MARKS ON THE SPREADER MUST BE BETWEEN THE TWO MARKERS ON THE
COMBUSTION CHAMBER (
).
The spreader has one mark on the 80, 70 and has two marks on the 60, 50, 40.
When installing the pipework ensure that:
a) Suitable union fittings are used at the first joint of all boiler connections.
b) The pipework will run through the cutouts provided in the outer case (
).
c) Drain off points are provided as appropriate.
d) Pipe sizes are suitable for the system design.
Pump (
A suitable pump e.g. Grundfos Selectric 4 or SMC Commodore with ball type isolating valves and
22mm compression fittings may be fitted inside the outer case.
The pump should be connected to the 3/4 in flow connection on the front of the heat exchanger
using the following standard fittings.
A
1 off
Elbow 3/4 BSP male x 3/4 BSP female
B
1 off
Conex straight connector 3/4 BSP male
x 22mm copper
C
3 off
22mm Yorkshire elbows
D
