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 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 500, on the wood burning chart above, follow the column to the 8"
flue size. Highlighted in red, the chart shows an RS 9 to be the proper
size chimney fan for this application. |

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.
EBC5 A pre/post purge control that would extend the
the fan cycle before and after gas is present for a fireplace or appliance.
