EXISTING

MASONRY CHIMNEY

The RFS22/RFS32/RFS42 may be installed using 4" diameter single wall vent up to an existing masonry chimney.(Fig. 10) This vent should then be connected to a 4" liner running the full height of the chimney, as it is mandatory in most jurisdictions that the chimney be lined.

Another option is 4" "B" vent directly off the fireplace(Fig.9

&11), going up to the chimney liner or up through the roof if no chimney exists.

A minimum 12 foot vent height is required to effectively vent this fireplace.
