Beckett CG10 manual Verify burner air tube assembly, Mbh

Section: Pre-installation Checklist

Verify burner air tube assembly

○The information in this section may be disregarded if the burner supplied by the appliance manufacturer is a matched component.

○Maximum firing capacity depends on the furnace pressure. Use the charts shown in Figure 3 and Figure 4, to verify the correct burner configuration for the input rate.

○Refer to Figure 5 to verify the air tube assembly length and mounting insertion dimensions.

The volume of the furnace also influences the combustion

process. R. W. Beckett Corp. recommends at least 1 cubic foot of furnace volume for each 150,000 BTU/Hr of firing rate.

Flames are shaped by their furnaces and by its flue locations.

Increased height and width can decrease the length requirement. When shaping is too severe flames impinge on the walls. Impingement causes CO and carbon deposits and may damage the wall. Maintaining these minimum dimensions should prevent impingement, but smaller furnaces may be acceptable depending upon the results of applications testing. We recommend factory testing of all new burner/furnace combinations by the furnace manufacturer and/or R. W. Beckett Corp.
