Mounting burner to appliance
Positive overfire pressure applications: When firing with posi-
tive overfire pressure, do not exceed the pressure specified
in the appliance manual.
Positive overfire pressure reduces maximum burner capacity.
See Table 1 notes for estimated reduction in burner capacity
with pressurized firing.
When using the adjustable flange, follow the steps in Figure 14
to prepare for pressurized firing.
Failure to comply could result in severe personal injury, death
or substantial property damage.
When using a welded flange burner, verify the insertion depth on the ap-
pliance and burner (see page 7).
If using the adjustable flange (Figure 14), measure the appliance insertion
depth to the set the position of the flange on the air tube. Tighten the flange
locking screws firmly. Prepare the appliance opening to the dimensions
shown in Figure 14. Also read page 7.
