Combustion Air Supply System
Installation Requirements
An intake grill will have to be installed with the same size of the total opening
as the combined air supply ducts on the unit. Make sure you have calculated
the restriction and selected the proper grill size.
The
BF-SS
fireplace is supplied with two or more combustion air duct
connection points. Do not reduce the size of the air supply system, or
restrict the air supply in any way. On any combustion air supply run longer
than 10 feet the duct should be increased in size to prevent a restriction.
A vacuum safety switch, located under the burners, will monitor the combustion
air supply pressure and will prevent the burner from igniting, or continuing
to burn if the pressure is negative, past 0.08WC.
For extremely long air supply runs the combustion air supply will have to
be power assisted.
