Quick Sizing.... Step 1
Determine the type of opening, measure and calculate.....
One-sided
A x B
Two-sided (See-through)
1.5 x A x B
Corner
A x B
Three-sided
( A + B ) x C
Free-standing
1.5 x A x B
Free-standing Round
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″ Flue Size)
NOTE: Clay liners are “called” by their OUTSIDE measurements, the INSIDE measurements may vary depending on the manufacturer and location.
EX. A 13×13 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 Exhausto fan required to fully exhaust the fireplace opening and flue system.
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.

RSHT High Heat Fan Wood / Gas Fireplaces
RSHT 009 - 016
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.
Wood stoves, coal stoves and fireplace inserts
If there are more than 2x90° elbows, a bigger fan may be necessary.

RS Chimney Adaptors will be necessary for any metal pipe installation.
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.

ASCA Air Cooled Steel Chimney Adaptor
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.
The adapter is designed to slide into the chimney for a tight fit. The outer diameter of the collar is 1/8″ smaller than the inner diameter of the chimney. The 5″ collar eliminates the need to secure the adapter externally.
