Verify Air Tube
The information in this section may be disregarded if the
air tube is supplied by the appliance manufacturer.
The following tube arrangements are available –
CF2500 - Tube KP -17.0.0 to 19.9 GPH
CF2500A - Tube KP -17.0 to 25.0 GPH
CF3500A - Tube KM -17.0 to 35.0 GPH or
Tube KR -17.0 to 35.0 GPH
Maximum fi ring capacity depends on the fi rebox
pressure. Use Table 2 to verify the correct air tube type
for the fi ring rate required. (Tube KR [CF3500A] is an
optional air tube combination for maximum capacity rate.
It requires a larger I.D.
fl ange Number 51631.)
See Figure 2 to verify the correct air tube length and air
tube combination code.
