ling materials capable of withstanding
mechanical stresses and flue heat
over time.
At any point of the flue the burnt gas
temperature shall not exceed the dew
point temperature. Maximum three
changes of direction can be made,
including the union to the stack/flue.
For changes of direction, use only cur-
ved components.
