Prepare burner and components
Do not install or operate the burner if any component is dam-
aged or if burner does not comply with the specifications of
Table 1b and other guidelines in this manual.
Combustion chamber minimum dimensions
• For applications that have not been specifically tested (OEM applications),
verify that the combustion chamber provides the minimum dimensions
shown in Table 1b and Figure 3b. For specific OEM applications,
the appliance testing ensures suitability of the chamber.
• Chamber dimensions may be larger than listed in Table 1b, but should
not be excessively large.
Air tube insertion length (UTL)
• Usable air tube length (UTL) is the distance from mounting flange to end
of air tube. Verify that the end of the air tube will be flush with, or no more
than ¼ inch short of, the inside of the appliance combustion chamber
front wall when the burner is mounted. See Figure 3b and Table 1b for
further information.

Note 1
Some tested appliances may operate satisfactorily with dimensions less than the above.
Note 2
Horizontal cylindrical chambers — diameter must be no less than column “W” above
Horizontal stainless steel cylindrical chambers — diameter at least 1 to 4 inches larger than column “W” above.
VC is the minimum diameter for vertical cylindrical chambers (refractory or refractory-lined chambers only).
Note 3
A corbel may help heat transfer in a larger boiler or furnace, provided it is recommended by the appliance manufacturer.
