OIL-FIRED, HORIZONTAL DELIVERY UNIT HEATERS
Modine model POR oil-fired unit heaters are built with time-tested and field-proven
components to provide optimum comfort and heating efficiency as high as 84%.
Standard features include:
• A long-life heat exchanger is made of corrosion-resistant, aluminized steel and roll-
formed to eliminate thermal stress. It contains a preformed, ceramic fiber fire-pot that
is lightweight, resilient, and resists both mechanical and thermal shocks.
• For ease of service, the heat exchanger is equipped with an inspection port,
two clean-out ports, and an amply-sized service door for removing fire pot when
replacement becomes necessary.
• A reliable, pressure-atomizing gun-type burner equipped with a stainless steel,
die-stamped flame-retention head that can increase combustion efficiency by as much
as 20 to 30 percent over non-flame retention-type burners.
• Beckett microprocessor-based ignition controller providing superior combustion and
safety monitoring.
• Onboard diagnostics with LED output for simplifying the lives of service personnel.
• Interrupted-duty ignition that disables the spark once ignition is proven. Older
technology uses a continuous spark that is noisy, prone to shorter lifespan, and not
energy efficient.
• Electronic oil igniter module with superior spark voltage (20kV) replaces traditional
bulky ignition transformers.
• Beckett CleanCut burner pump that uses a solenoid valve to instantly cut oil flow on
shutdown, eliminating soot formation from coasting stops.
• Two stage pump with PSC motor provides maximum fuel pressure delivery, even in
high lift applications.
• Finger-proof fan guard.
• The unit casing is treated for protection against corrosion prior to the application of
the attractive gray-green, baked-on polyester powder coat paint finish.
• Accessory Outside Combustion Air Kit converts the burner to accept outside
combustion air piping for tight building applications.
• Three Sizes • Pressure-Atomizing, Gun-Type Oil Burner • Cad-Cell Safety Shut-Off • Electric-Spark Ignition
• Fan and Limit Control
