Modine Commercial Workspace Heater - 150K BTU/Direct Spark Ignition/NG/Separated Combustion/Single Stage w/Aluminized Steel Heat Exchanger - PTS150AS0111

Modine Commercial Workspace Heater - 150K BTU/Direct Spark Ignition/NG/Separated Combustion/Single Stage w/Aluminized Steel Heat Exchanger - PTS150AS0111

Features

• Specifically designed for environments with hostile atmospheric conditions, such as chemicals, high humidity or negative pressure
• Combustion air is brought in from outside the heated area - either from outdoor air or from an adjacent room - eliminating the need to use contaminated indoor air for combustion
• In-shot burners fire each heat exchanger tube for reliable performance, ease of service and decreased noise on ignition
• Same-size vent and combustion air inlets throughout product line makes installation easier
• Longer allowable vent lengths (up to 50′ vs 30′) versus previous line, providing greater installation options
• Round vent pipe and combustion air inlet pipe connection
• Automatic reset vent pressure switch is designed to prevent operation of the main burner in the event there is restricted venting of the flue
• Integrated direct spark control board provides digital control of the air mover, inducer, ignition, gas valve and flame sense
• Control Step Down Transformer used to step down from 115v to 24v for the gas controls, fan delay relay, field supplied motor start and more
• Remote flame sensor verifies ignition of all burners, monitors the flame single and communicates with the integrated circuit board
• High limit control switch is mounted in the air stream and will shut off the gas supply in the event of overheating
• 4" vent & combustion air connection
