Separated Combustion Gas-Fired Unit Heaters

Commercial Gas-Fired Heaters - 350/280K BTU
Modine�s PTS/BTS separated combustion unit is specifically designed for environments with hostile atmospheric conditions, such as chemicals, high humidity, or negative pressure. On these units, 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 make installation easier.
• Longer allowable vent lengths (up to 50? vs 30?) 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 communicated with the integrated circuit board
• The high limit control switch is mounted in the air stream and will shut off the gas supply in the event of overheating
• Designed, Engineered & Assembled in the USA

Accessories:

• Vertical Deflectors Blades
• 30, 60 and 90 degree air deflector hoods
• Horizontal Concentric Vent Kit
• Pipe Hanger Adapter Kits
• Natural Gas to Propane Gas Conversion Kits
• Single or Two-Stage Room Thermostats
• Room Thermostat Guard

Things To Consider

1. How many BTU�s do they need?
2. What type of heater do they need? (Natural Gas, Electric, Propane)
3. Do they have 240V power? Do they have Phase I or Phase 3 power?
4. Do they need a vent stack for separated combustion?
5. Do you need a thermostat or controller?
6. How are they circulating or moving heat in the space?
