GENERAL PRODUCT INFORMATION
Principal of Operation
Power Flame Type C Burners incorporate the principles of
pressure atomization for oil and multiple orifice, venturi
operation for gas. The total package utilizes the forced
draft, flame retention concept. The Type C burner is listed
and labeled by Underwriters Laboratories, Inc. Capacities,
when fired at 0.2" w.c. positive combustion chamber
pressure, range from 3 to 136.4 GPH of commercial grade
#2 fuel oil and/or 98 to 19,100 CFH of natural gas. Air for
combustion is furnished by an integrally mounted combus-
tion air fan. The Power Flame packaged combustion
system can be operated under positive or negative furnace
pressures with clean, efficient combustion in a wide range
of combustion chamber conditions. (Consult page 6 for
appropriate ratings.)
Power Flame Type C Burners are designed to produce
greater flame turbulence and reduce flame size. As a
result, they require less combustion volume for complete
combustion and can be easily fired under positive furnace
pressure. Forced draft pressurized operation requires
stacks of smaller diameter and height.

28 General Oil Start Up Procedure
The Power Flame C Burner is a totally packaged and
factory tested combustion system offering single unit
responsibility. The package incorporates accurate control
of the fuel-air ratio throughout the firing range with the
resultant controlled flame patterns and clean combustion
for maximum efficiency.
Combustion air flow is controlled by a multi-louvered
damper assembly. The combustion air is supplied by an
integral motor-driven blower, which discharges into the
burner blast tube assembly. High turbulence flow is
controlled by means of an adjustable fan diffuser system.
Various system mode operations are obtained by
applying appropriate control valves and fuel/air actuators.
Units are capable of operating in modes consistent with
specific demand requirements, from fixed or on-off through
full modulation.
The air/fuel ratio is established at the time of start-up and
proven with combustion test equipment to provide the
lowest practical oxygen with a clean flame.
