maximum Resistance Factor equal to 100. The maximum permissible Re-
sistance Factor corresponds to the resistance detected with the maximum
ES
permissible pipe length with each type of Terminal Kit installed. This
information enables calculations for verifying the possibility of various
configurations of fume exhaust systems.

Diaphragm installation. To ensure correct boiler operation, a diaphragm
(see figure) must be installed on the outlet of the sealed chamber before the
intake and exhaust duct. The choice of a suitable diaphragm depends on
the type of duct used and its maximum length: calculations can be made
