Enervex Chimney Fans
Model RS Chimney Fan Selection
Wood and Gas Fired Fireplaces and Stoves

QUICK SIZING....  STEP 1      Determine the type of opening, measure and calculate.....

         
One-sided   Two-sided (See-through)   Corner   Three-sided   Free-standing   Free-standing Round
A x B   1.5 x A x B   A x B   ( A + B ) x C   1.5 x A x B   1.185 x A2

QUICK SIZING....  STEP 2
Determine the type of flue and measure the INSIDE measurement... use the chart below to convert square and rectangular to round.

CONVERSION OF Rectangular / Square to Round Flues

Measure the INSIDE ( side to side ) measurements of the clay liner.

Ex...  The INSIDE measurement of 6 x 10" on a clay liner is equivalent to

10 (dim. A) - 6 (dim. B) = 8 (8" Round)

NOTE:  Clay liners are "called" by their OUTSIDE measurements, the INSIDE measurements may vary depending on the manufacturer and location.
EX. A 13x13 clay liner may only have an INSIDE measurement of 10" x 10"


QUICK SIZING....  STEP 3   
Use of the following fan selection tables below to calculate the Enervex fan required to fully exhaust the fireplace opening and flue system.

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.

Check that there are no more than 2x90 elbows and no more than 30 of height. If there are more than 2x90 elbows, use a bigger fan.


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.


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.

Check that there are no more than 2x90 elbows and no more than 30 of height. If there are more than 2x90 elbows, use a bigger fan.

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.

ADC 100  A pre/post purge control that would extend the the fan cycle before and after gas is present for a fireplace or appliance.

MFD Mechanical Fireplace Damper. Prevents excess heat from escaping through the chimney when the fireplace is not in use.
