➀ Ratings shown are for elevations up to 2,000 Ft. For elevations above 2,000 feet, ratings should be reduced at the rate of 4% for
each 1,000 feet above sea level. (In Canada see rating plate.) Reduction of ratings requires use of a high altitude kit.
➁ Data taken at 65°F ambient and unit fired at full-rated input. Mounting height as measured from bottom of unit, and without
deflector hoods.
➂ Also certified for residential installations.

DO NOT LOCATE ANY GAS-FIRED UNIT IN AREAS WITH CHLORINATED,
HALOGENATED, OR ACIDIC VAPORS IN ATMOSPHERE.
At 93% thermal efficiency for all model sizes, Modine’s Effinity
93®
condensing unit heater
features the highest efficiency available in North America for commercial and industrial,
as well as residentially certified (sizes 110 and smaller) gas-fired unit heaters. This industry
leading efficiency is a result of the coupling of our Conservicore
®
secondary heat
exchanger technology with our robust tubular primary heat exchanger design. The
Conservicore
®
technology features a secondary recuperative heat exchanger fabricated
from AL29-4C
®
stainless steel. This material is superior to other lower grades of stainless
steel and aluminum, resulting in outstanding ability to withstand the corrosive environment
of condensing gas fired equipment.
Available in ten model sizes with input ranges from 55,000 to 310,000 Btu/Hr, Modine offers
application flexibility unmatched in the industry. The separated combustion units draw
combustion air from outside to ensure that the unit will always have plenty of fresh, clean
air for combustion while increasing the overall heating efficiency. Venting material to be
used is PVC, an extremely cost effective vent system.
• 93% thermal efficiency for fuel savings.
• Conservicore
®
secondary heat exchanger made of AL29-4C
®
stainless steel.
• A sealed compartment protects the combination gas valve, ignition control, manifold,
and burner from the environment.
• External gas connections.
• Uses natural or propane gas (field convertible from natural to propane gas).
• Certified for residential (55-110MBH), commercial, and industrial use.
• Standard Contractor Convenience Package with diagnostic LEDs, disconnect switch,
and condensate pump outlet.
• Standard power exhaust simplifies side-wall or roof venting with small-diameter pipe.
• Horizontal or vertical two-pipe or concentric venting options.
• Permanently lubricated motor for trouble-free dependability.
• Full 10-year warranty on both heat exchangers.

Heaters are designed for use in heating applications with ambient temperatures between 40°F and 80°F. Heaters should not be
used in applications where the heated space temperature is below 40°F. The combination of low space and combustion air
temperatures may result in condensate freezing in the secondary heat exchanger and/or condensate drain.
