Instruction Manual – Model CF1400 Oil Burner
❏Verify firing rate
Figure 2 - Air tube mounting dimensions
•Refer to appliance manufacturer’s instructions (if avail- able) for firing rate and nozzle selection. Otherwise, the maximum recommended firing rate for the burner depends on the length of the firing chamber and the distance from the burner center to the chamber floor. Verify that the cham- ber dimensions are at least as large as the minimum values given in Figure 1. If the appliance dimensions are smaller than recommended, reduce the firing rate accordingly.

•The information in this section may be disregarded if the air tube is supplied by the appliance manufacturer.
•Two tube arrangements are available –
Tube A — 4.0 to 11.0 GPH per | Table 2 |
Tube B — 7.0 to 13.6 GPH per | Table 2 |

①Install the burner with a 2° pitch as shown.
•Maximum firing capacity depends on the firebox pressure. Use Table 2 to verify the correct air tube type for the firing rate required. Use Tube B only when Tube A cannot pro- vide the firing rate required.
•See Figure 2 to verify the correct air tube length and air tube combination code.
