and must comply with all applicable codes.
Verify burner components —
Burner box, Model CF1400 or CF2300A

Mounting fl ange kit
Pedestal mounting assembly kit (recommended)
Oil 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 fi ring rate in the 300 psig column (high
fi re rate).
Select the corresponding nozzle from column 1 (Rated
gph @ 100 psig).
Verify fi ring rate
Refer to appliance manufacturer’s instructions (if avail-
able) for fi ring rate and nozzle selection. Otherwise, the
maximum recommended fi ring rate for the burner de-
pends on the length of the fi ring chamber and the distance
from the burner center to the chamber fl oor. 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 fi ring
rate accordingly.
