Oil nozzle, per Table 1 — Only 45° to 70° solid pattern
nozzles are recommended unless otherwise specifi ed
by appliance manufacturer. (See specifi c appliance
recommendation sheet or refer to OEM Spec Guide). Find
the required fi ring rate in the 140 psig column (factory-set
fuel unit pressure). Select the corresponding nozzle from
column 1 (Rated gph @ 100 psig).

Verify fi ring rate
Refer to appliance manufacturer's instructions (if
available) for fi ring rate and nozzle selection. Otherwise,
the maximum recommended fi ring rate for the burner
depends 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 minimum values given in Figure 2. If the appliance
dimensions are smaller than recommended, reduce the
fi ring rate accordingly.
Verify air tube
The information in this section may be disregarded if the
air tube is supplied by the appliance manufacturer.
Two tube arrangements are available –
CF500
CF800
Maximum fi ring capacity depends on the fi rebox pressure.
Use Table 2 to verify the correct air tube type for the fi r-
ing rate required. Use Tube B only when Tube A cannot
provide the fi ring rate required.
See Figure 3 to verify the correct air tube length and air
tube combination code.
