Modine Commercial Effinity Heater - 260K BTU/High-Efficiency Condensing/Direct Spark Ignition/LP/Separated Combustion/Single Stage w/Aluminized Steel Heat Exchanger - PTC260AS0121

Features

• Made in the USA
• Separated combustion - drawing 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
• Helps promote a clean air growing environment - combustion fumes are vented outside, away from your plants
• Fuel savings - up to 97% efficiency allows you to save otherwise wasted energy and money
• Dependable and consistent performance accompanies Modine’s Conservicore Technology - providing power exhauster and dual heat exchangers
• Secondary heat exchanger is made of AL29-4 stainless steel and comes with a 10-year warranty - eliminating corrosion concerns and extending the life of your investment
• Building Management System integration capabilities allow these units to be added easily to any existing system
• Energy Saver Controls - as the temperature increases, the gas is disabled and stratified ceiling air is used to heat the space below. Once the ceiling air temperature decreases, the gas re-engages and heats the air
• Contractor Convenience Package featuring a condensate pump convenience outlet, unit on/off switch, heater function status indicator lights, and external terminals for thermostat wiring
• Just one Effinity heater can lower CO2 output by thousands of pounds annually
• 4" vent & combustion air connection
• Liquid Propane
• 260,000 BTU
• Direct spark ignition
• Single Stage Energy Saver Controls
• Aluminized steel heat exchanger
