Description

InnoFlue increaser, 3" to 4". Steps a vent run up to a larger diameter. Eccentric, so one side of the run stays flush — useful where the vent follows a ceiling or wall. Polypropylene, UL 1738 listed for Category IV condensing appliances, where acidic flue condensate would attack a metal vent. Push-fit gasketed joints need no cement, primer or cure time.
