  • Multiple product options available

    Heaters provide 83% thermal efficiency and are outfitted with a tubular heat exchanger and a direct spark inshot burner ignition which requires no gas/air mixture regulation adjustments. Power venting allows horizontal venting through side walls; use single- or double-wall vent pipe for vertical venting, single-wall for horizontal venting.

    Propeller-Type—A sturdy 2-point suspension provides balanced installation.

    Blower-Type—Heaters feature a fan time delay to help eliminate cold air at startup, while a removable burner access panel provides fast, easy maintenance and inspection. Field-adjustable for vertical or horizontal venting

  • Dayton Gas Unit Heaters, Separated Combustion Dayton Gas Unit Heaters, Separated Combustion
  • Multiple product options available

    Heaters pull in outside air for combustion, which enables them to operate in areas having slight negative pressures (near exhaust fans, etc.), with no adverse effect on combustion or venting. Burners are isolated from dust, humidity, and nonhazardous chemicals, to allow heating of special environments. LED diagnostic control board provides simple operation. 24V thermostat required (sold separately). Direct spark inshot burner ignition, except on select models.

    Propeller-Type—Heaters offer slightly higher air flow than Blower-Type models.

    Blower-Type—Units can overcome up to 0.2 in. External Static Pressure (ESP).

    Heaters use outside air for combustion, enabling operation in areas having slight negative pressures (near exhaust fans, etc.), with no adverse effect on combustion or...More
