6.1 Heatingsystem
Install the CH-system in accordance with present legislation.
The pipe work headers are available in 2 dimensions, i.e. DN65 and DN100 and are
connected to one another by the ange couplings and gaskets, M12 or M16x55 bolts,
spring washers and nuts. The low velocity header and the complete installation can then
be connected to it.
Lowvelocityheader
There are 3 low velocity headers available:
0310335 Low velocity header for 1 or 2 XL boilers to max. 200kW (g. 6.1.a)
Boiler connections are 4x 1 1/2", installation connections are 2x 2". The low velocity
header must be suspended in the pipework. Supplied with automatic air vent, drain
valve and pocket for temperature sensor T10.
0310272 Low velocity headers DN65 to 452kW (g. 6.1.b)
0310273 Low velocity headers DN100 to 960kW
The low velocity headers comes standard with adjustable feet, automatic air vent,
drain valve, pocket for temperature sensor T10, M12 or M16x55 bolts, spring washers
and nuts. The low velocity header can be positioned on either the left or right hand
side of the pipe work headers.
0310290 Temperature sensor T3/T10 (g. 6.1.c)

header.
Setofbends
The low velocity header can be positioned at a 90° angle. A set of bends may be used
for that purpose.
0310274 Bends set DN65 ow/return (g. 6.1.d)
0310275 Bends set DN100 ow/return
Blankinganges
The ends of the pipe work headers have to be tted with blanking anges. The blanking
anges come standard with a fully congured delivery, including bolts, spring washers
and gaskets.
0310276 Blanking ange set DN65 ow/return 2 items (g. 6.1.e)
0310277 Blanking ange set DN100 ow/return 2 items
Welded-onanges
Upon request, welded-on anges are available to connect CH-pipe lines to the secondary
side of the low velocity header and to connect the gas line.
0310336 Welded-on ange set DN65 ow/return 2 items + DN50 gas 1 item (g. 6.1.f)
0310337 Welded-on ange set DN100 ow/return 2 items + DN65 gas 1 item
