This table is designed
as a guide to the selection of combivent for the correct application.
Once the flue size has been calculated referring to the kilowatt rating
for that diameter, will indicate the suitable combivent size.
A square unit has more
free area available than a circular system, therefore, will be suitable for
higher appliance ratings than the equivalent circular units.
