CONVERSION OF Rectangular / Square to Round Flues

The "opening in square inches" refers to the fireplace or appliances over-all face opening. Example :  In a small wood burning fireplace, if the hearth opening is 18" x 24" with an 8" round ( INSIDE MEASUREMENT ) clay liner in a brick and mortar chimney we would... Multiply the length and width, in this case 18" x 24" = 432 square inches.  Being less than 600, on the wood burning chart above, follow the column to the 8" flue size.  Highlighted in orange, the chart shows an RS 9 to be the proper size chimney fan for this application.

The RED background indicates that the fan will most likely create some air-flow noise due to a high air velocity in the chimney.

The BLUE background indicates the fan base will not cover the chimney opening and a special adapter must be used.

If there are more than 2x90° elbows, a bigger fan may be necessary.

Short Flue System? The RSHT Chimney Fan is a high temperature exhaust fan that can handle 1000+ degrees at the termination.

Gas fireplaces will need additional controls...

PDS (Proven Draft Switch) Safety control that senses a draft.  A pressure sensor that ties into the log set or appliance controls and would shut the gas off if the draft became negative.

ADC100 -  A pre/post purge control that would extend the the fan cycle before and after gas is present for a fireplace or appliance.

Note: The RED background indicates that the fan will most likely create some air-flow noise due to a high air velocity in the chimney.

The BLUE background indicates the fan base will not cover the chimney opening and a special adapter must be used.

If there are more than 2x90° elbows, a bigger fan may be necessary.

SCA - Steel Chimney Adapter The ENERVEX Steel Chimney Adapter is used when installing the RS chimney fan on the top of a single, double or triple wall steel chimney. The adapter is designed to slide into the steel chimney for a tight fit. The outer diameter of the collar is 1/8” smaller than the inner diameter of the steel chimney, and has a 5” deep collar.  SCA Adaptor             Product Info PDF

ASCA - Air-cooled Steel Chimney Adapter The ENERVEX Air-Cooled Steel Chimney Adapters are used specifically when installing a chimney fan on the top of a double-walled, air-cooled chimney.
