GENERAL PRODUCT INFORMATION
Principal of Operation
The Power Flame NOVA Plus™ Combustion System employs a patented, fully premixed,
surface stabilized combustion technology to provide proven ultra-low NOx solutions - Sub 9 to
12 PPM - for commercial, industrial, and process applications. Premixing fuel and air assures
complete combustion with minimal levels of CO and unburned hydrocarbons. The all metallic
firing head guarantees reliable and consistent performance at the operating conditions
necessary to provide single digit NOx emissions. The NOVA Plus is a simple, cost effective,
field proven system designed to meet today’s most stringent emissions requirements.
Power Flame provides a U.L. listed, factory tested package tailored to your job specific
requirements up to NVC10. The NOVA Plus is suitable for use on firetube and watertube boiler
applications, as well as process heaters. It will operate with uniform heat flux and excellent
flame stability over a broad range of operating conditions.
The modular concept that is the basis for all Power Flame burners keeps the initial investment
low and maintenance costs at a minimum across the life of the burner. The NOVA Plus is fitted
with a state of the art control system and integral panel.
Combustion air flow is controlled by a multi-louvered damper assembly. Combustion air is
supplied by an integral motor-driven blower, which discharges into the burner mixing spool
assembly. Gaseous fuel and air mix in the burner mixing spool. The premixed gaseous fuel
and air flow down the center plenum of the cylindrical element and through the metal material.
Ignition occurs on the outer surface.
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 and single digit NOx
emissions.
A Flame Safeguard Controller programs the firing cycle. The operating cycle is sequenced to
ensure normal and safe conditions before fuel can be introduced into the combustion chamber
area. The complete firing cycle is supervised to ensure that ignition of main flame is properly
established and maintained. Flame monitoring is provided by an ultraviolet type scanner.
The limit circuit includes the operating limit control to maintain a set operating pressure or
temperature, as well as a high limit control to guard against excessive pressure or temperature.
Low water and other similar safety controls can be interlocked into the burner control system to
satisfy specific job and/or code requirements.
The control circuit is normally 120 volts. A control circuit transformer may be furnished to
provide the 120 volt control circuit for a polyphase motor application.
The pre-wired Control Panel is mounted and wired as an integral part of the burner in
accordance with recommendations of Underwriters Laboratories, Inc. and The National
Electrical Code. Components are wired to numbered terminal strips. Panel and burners are
factory fire tested before shipment. Comprehensive wiring and gas piping diagrams are
furnished with each burner in accordance with individual job or application requirements. Wall
mounted or free standing control panels are also available.

adjustments without consulting with
the burner service company.
4.
Never attempt to light the burner if
combustion chamber contains any
unburned fuel or gases.
5.
Never throw waste paper, rags, garbage
or other waste materials into the
combustion chamber.
6.

without first covering the burner with
waterproof material.
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause injury or property
damage. Refer to the burner manual. For assistance or additional information consult a qualified
installer, service agency or the gas supplier.
Preparation for Start Up - All Fuels
1.
Ensure that the system is in working order.
If heat exchanger is a boiler, ensure that
proper water level is available.
2.
Set the burner control panel switch to the
OFF position.
3.
Combination Gas Burner – set the fuel selector
switch to the fuel to be burned.
Start Up
1.
Manually open and close the main gas shut off
cock, leak test cock and pilot cock to determine
that they operate freely. Open all three cocks.
(Reset low gas pressure switch if supplied).
2.
Set the main power switch and burner panel
control switch to the ON position. Wait 30
seconds and turn up thermostat or operating
control to the desired setting.
3.
The burner blower motor will start and after
a suitable pre-purge period (this will vary with
the type of flame safeguard control supplied –
but will usually be a minimum of 30 seconds),
the burner pilot will light, after which the main
flame will be established.
4.
If the system does not respond properly,
contact your qualified burner service company.
EXTENDED SHUT DOWN
1.
Place main power switch and burner control panel switch in the OFF position.
2.
Close all gas valves.
3.
Cover burner to protect it from dust and dampness.
