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 fi ring capacity depends on the furnace 
pressure. Use the charts shown in Figure 3 and 
Figure 4, to verify the correct burner confi guration 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 infl uences the combustion 
process.  R. W. Beckett Corp. recommends at least 1 
cubic foot of furnace volume for each 150,000 BTU/Hr of 
fi ring rate. 
Flames are shaped by their 
furnaces and by its fl ue locations.  
Increased height and width can decrease the length 
requirement.  When shaping is too severe fl ames 
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.
