Verify Air Tube

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

○On the CF1400, there are two tube arrangements available –

-Tube A — 4.0 to 11.0 GPH per Figure 3.

-Tube B — 7.0 to 13.6 GPH per Figure 3.

○The CF1400 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 provide the firing rate required.

○On the CF2300, there are two tube arrangements available –

-Tube A — 7.0 to 19.9 GPH per Figure 3.

-Tube B — 10.0 to 19.9 GPH per Figure 3.

○The CF2300 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 provide the firing rate required.

○See Figure 3 to verify the correct air tube length and air tube combination code.

Note: 10% turndown indicates sufficient reserve air to reduce the CO2 in the flue to 90% of its value. The above ratings may vary 5% due to variations in actual job conditions.

*CF2300 can fire higher but is limited by UL requirements.
