‰Verify firing rate

yRefer to appliance manufacturer’s instructions (if available) 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 chamber 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.

‰Verify air tube

yThe information in this section may be disregarded if the air tube is supplied by the appliance manufacturer.

yTwo tube arrangements are available –

Tube A — 1.65 to 2.00 GPH

Tube B — 2.00 to 3.75 GPH

yMaximum firing capacity depends on the firebox pressure. Use Table 2 to verify the correct air tube type for the fir- ing rate required. Use Tube B only when Tube A cannot provide the firing rate required.

ySee Figure 2 to verify the correct air tube length and air tube combination code.
