A. See page 2 for further model number information.
B. The flame sensor shown - UV (Ultra Violet) or CC (Cad Cell). Other flame
sensors such as Lead Sulfide and photo cell are available to comply with
specifications or codes.
C. If separate pump is supplied, HP may be reduced. For positive pressure
applications on C1 burners with integral pump firing over 8 GPH or some OEM
boilers, a 1/2 HP motor and oversized fan are required on oil and gas/oil burners.
D. Capacities listed are based on 0.20" W.C. positive pressure. Derate capacities
approximately 5% for each +.50" W.C. combustion chamber pressure,
except for C5-OB and C5-G(O)-30B, which are rated for 250 BHP at +1.2"
W.C. All capacities based on 2000' elevation. Derate capacity by 4% for each
additional 1000' elevation.
E. At inlet to main shutoff cock with burner operating at maximum input rate.
If auxiliary gas valves are used, C2-G(O)-20A through C4-G(O)-30 inlet
pressure of 28" (1#) are permitted when using optional 325-3 pilot regulator.
F. Model numbers will always reflect the standard U.L. listed gas train sizes
to correlate with U.L. input listings. The actual train size may vary, depending
on local gas supply pressures available.
G. and H. Suction line and oil filter must be sized to provide these suction capacities.
Do not size suction lines or filter capacities based on burner firing rates.
See page 11 for further information.
I. C2-OB will be supplied with a UV sensor if firing rate is above 20 GPH
(unless specified otherwise).
