Dimensional data
Mounting burner to appliance
Positive overfire pressure applications: When firing with
positive overfire pressure, do not exceed the pressure
specified in the appliance manual.
Positive overfire pressure reduces maximum burner ca-
pacity. See Table 1 notes for estimated reduction in burner
capacity with pressurized firing.
When using the adjustable flange, follow the steps in Fig-
ure 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
appliance and burner (see page 7).
If using the adjustable flange (Figure 14), measure the appliance inser-
tion 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.
