BOILER WATER CIRCUIT DIAGRAM
INTRODUCTION
The icos system m3080
boiler is a fully automatically
controlled wall mounted, low water content, fanned flue
condensing gas boiler.
Note.
Due to the high efficiency of the boiler a plume of water
vapour will form at the terminal during operation.
The output is fully modulating with a range of:
8.8 to 23.4kW (30,000 to 80,000 Btu/h)
The boiler is supplied fully assembled with circulating pump,
pressure gauge, safety valve and expansion vessel.
Variable temperature control is fitted on the user control.
The boiler casing is of white painted zintec coated mild steel.
The boiler temperature controls are visible at the bottom RHS
of the front panel.
The heat exchanger is of aluminium.
The boiler is suitable for connection to fully pumped, sealed
water systems ONLY.
The system pipework MUST include drain cocks in appropriate
places.
Pipework from the boiler is routed downwards as standard, but
may be routed upwards behind the boiler using the stand-off
frame (supplied in a separate kit).
