ROOF VENT WITH STEEL CHIMNEY FLUE
In installation of the chimney fl ue, always guarantee an inspection door to enable periodic cleaning
of soot and a condensate collector with drainage to evacuate any condensate.
If the smoke pipe is installed completely externally, you should make it fully in stainless steel with a
double wall to guarantee better resistance to atmospheric agents and adequate temperature of the
smoke vent.
