Performance Selection Data(cont'd.)

Airstream velocity across and through your burner's mixingplates must be kept uniform and within desired limits by use of asilhouette profile plate through which the burner fires. A 6" (mini-mum) profile plate should be installed surrounding the interior ductwalls at the leading edge of your burners mixing plates.

Optimum design ranges for the various burner types are shown

in the above graphs. Velocities (SFPM) are measured with avelometer directly in the duct at the plane of the profile plate andleading edge of burner mixing plates.

To determine profile opening areas, add burner displacementareas (Ft2/section) from Table 1 for your complete burner assemblyto "Net Free Area" of your duct:

"Net Free Area" of Duct (Ft2) = Fan Volume (SCFM)Velocity (SFPM)

Net Free Area (Ft2) + Burner Displacement (Ft2) = Profile Area (Ft2)

Various duct size/profile area relationships may give slightlydifferent field site data than is shown in Table 2. Velocities should

always be confirmed and established by use of a velometer onactual field site installation.
