Up to 97% thermal efficiency for all model sizes, Modine’s
Effinity
®
condensing unit heater features the highest efficiency
available in North America for 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.
This catalog describes the design benefits, construction
features, performance data, unit selection procedure, and the
optional and accessory devices available for the Modine Effinity
®
Condensing Unit Heater, Models PTC & BTC.
WARNING
1. Do not locate ANY gas-fired unit in areas where chlorinated,
halogenated, or acidic vapors are present in the atmosphere.
2. Appliances must not be installed where they may be
exposed to a potentially explosive or flammable atmosphere.
CAUTION
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.

Based on a natural gas rate of $1.10/Therm. Actual realized savings can vary
significantly based on a number of changing factors including, but not limited to,
fuel prices, climate, building use or construction, etc.
Compares 93% efficient against 65% seasonal efficient gravity vented and
78% seasonal efficient power vented.
Use 3500 for Alaska and Canada.
