C53
Roof and wall terminals (see page 43) and expanders and/or condensate trap/collector must be obtained by M&G.
For pressure drop calculation of appliance type C53 use the table for pressure drop per component and the table for total pressure drop calculation.
See page 32.
For total available pressure drop see table on page 33.
6.5.5 C63
C63 appliances may only be equipped with Gastec QA materials and terminals or according NEN 14989-2
Note: When using a C63 type flue configuration, it is essential to ensure that C63 is allowed in the country where the boiler is installed.
It is recommended to use a full aluminium flue system. A PP (Temperature class T120) or stainless-steel flue system can also be used (See TPW table
below). In this case the condensate must be drained before it flows back into the aluminium parts of the boiler. Otherwise aggressive condensate
from the non-aluminium flue system can corrode the aluminium parts of the boiler. A condensate trap/collector must be mounted just before
entering the silencer(s) of the boiler (also see 6.6.1 general).
