❏  
Verify firing rate
• 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.
❏  
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 –
Tube 
KG
 —   7.0 to 19.9 GPH per 
Table 2
Tube 
KS
 — 10.0 to 19.9 GPH per 
Table 2
• 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 
KS
 only when Tube 
KG
 cannot
provide the firing rate required.
• See 
Figure 2
 to verify the correct air tube length and air
tube combination code.

flue to 90% of its value.
