Vent system
 
The  fl ue gas venting system must be in good condition 
and must comply with all applicable codes.
Verify burner components —
Burner box, Model CF1400 or CF2300A
Air tube assembly
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.
