Beckett CF2300 Nozzle capacities, ‰ Vent system, ‰ Verify burner components, ‰ Verify firing rate

‰Vent system

The flue gas venting system must be in good condition and must comply with all applicable codes.

‰Verify burner components —

yBurner box, Model CF1400 or CF2300A

yAir tube assembly

yMounting flange kit

yPedestal mounting assembly kit (recommended)

yOil nozzle, per Table 1 — Use only 45° to 70° solid pattern nozzles unless otherwise shown by appliance manufacturer or on the burner nameplate rating label.

Find the required firing rate in the 300 psig column (high fire rate).

Select the corresponding nozzle from column 1 (Rated gph @ 100 psig).

‰Verify firing rate

Refer to appliance manufacturer’s instructions (if avail- able) for firing rate and nozzle selection. Otherwise, the maximum recommended firing rate for the burner de- pends on the length of the firing chamber and the distance from the burner center to the chamber floor. Verify that the chamber dimensions are at least as large as the mini- mum values given in Figure 2. If the appliance dimen- sions are smaller than recommended, reduce the firing rate accordingly.
