Power Gas Burners
MPG Series
Power Gas Burners
The MPG series of gas burners have been developed
with modular construction to make them adaptable to
many applications. The MPG series is available with
the blower on top as standard and also available for the
tighter applications with the blower on the bottom. The
burners have been UL and UL-C approved. We can
provide optional valve trains and controls to meet
ASME CSD-1, Factory Mutual, NFPA and GAP
(formerly IRI) specifications.
At the heart of the MPG burner efficiency is the
innovative burner gas manifold and its stainless steel
retention plate, precision engineered to thoroughly mix
gas fuel and combustion air for increased combustion
efficiency. With less excess oxygen required for
combustion, combustion efficiencies can be increased.

MPG 2.5G
with Optional Control Cabinet
The MPG series comes standard with a 120V electronic
microprocessor flame safeguard and flame rod sensing
or is available with optional UV sensing.
The MPG series of burners can be applied to numerous
applications. The standard product is completely factory
assembled and fire tested. The standard burner style of
firing is on-off with slow opening diaphragm gas valve
and fixed air shutter. We have available Hi-Lo-Off firing
or 3-1 and 10-1 turndown modulation capabilities. For
OEM models, we offer numerous options as well as
unassembled valve trains and welded flanges to fulfill
many application requirements.
The Unipower MPG GB burners are provided with a 24
volt electronic intermittent pilot ignition module with self
diagnostic features employing the flame rectification of
flame detection. A 120 volt ignition transformer insuring
reliable pilot ignition is standard.
