The secondary side can provide either 20%u00b0 or 11%u00b0 DT depending upon which low loss header is selected.Dimensions in mm with DN100 collector pipes2 boilers 3 boilers 4 boilers 5 boilers 6 boilers 7 boilers 8 boilersA Total width 1,060 1,590 2,120 2,650 3,180 3,710 4,240B Free space required for mounting the blanking flanges (1)50 50 50 50 50 50 50C Total height for a cascade with %u2264 70kW boiler models1,579 1,579 1,579 1,579 1,579 1,579 1,579C Total height for a cascade with %u2265 90kW boiler models1,748 1,748 1,748 1,748 1,748 1,748 1,748D Free space above the boilers (recommended minimum)(2)700 700 700 700 700 700 700E Free space in the front of the boilers (recommended)1,000 1,000 1,000 1,000 1,000 1,000 1,000F Total depth for a cascade with %u2264 70kW boiler models560 560 560 560 560 560 560F Total depth for a cascade with %u2265 90kW boiler models631 631 631 631 631 631 631G Flow connection DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6H Return connection DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6 DN100 PN6I Gas connection DN65 PN16 DN65 PN16 DN65 PN16 DN65 PN16 DN65 PN16 DN65 PN16 DN65 PN16J Free space required for expansion vessel102 102 102 102 102 102 102(1) When fitting a blanking flange with an expansion vessel connection, make sure there is enough space for fitting the vessel.(2) Make sure there is enough space for the flue gas system.Dimensions in mm with DN65 collector pipes2 boilers 3 boilers 4 boilers 5 boilers 6 boilers 7 boilers 8 boilersA Total width 1,060 1,590 2,120 2,650 3,180 3,710 4,240B Free space required for mounting the blanking flanges (1)50 50 50 50 50 50 50C Total height 1,579 1,579 1,579 1,579 1,579 1,579 1,579D Free space above the boilers (recommended minimum)(2)700 700 700 700 700 700 700E Free space in front of the boilers (recommended)1,000 1,000 1,000 1,000 1,000 1,000 1,000F Total depth 560 560 560 560 560 560 560G Flow connection DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6H Return connection DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6 DN65 PN6I Gas connection DN50 PN16 DN50 PN16 DN50 PN16 DN50 PN16 DN50 PN16 DN50 PN16 DN50 PN16J Free space required for expansion vessel102 102 102 102 102 102 102Note: Cascades up to 460kW are DN65, anything over 460kW is DN100.70 Gas Boilers
