Indoor Separated Combustion Duct Furnace
Modine indoor separated combustion duct furnaces are designed and engineered to deliver superior performance in a variety of applications. Designed for use within a building’s ductwork with upstream air mover by others.
Separated combustion duct furnaces are specifically designed for buildings with hostile atmospheric conditions, such as high humidity or negative pressures.
Modine Model DFS
- ETL certification for use in the US and Canada
- 81% thermally efficient
- 20-gauge aluminized steel cabinet
- 115V control step down transformer with 24V gas controls
- 409 Stainless steel heat exchanger, drip pan
- Stainless steel burner with stainless steel separator strip
- Certified to 3.0” W.C. external static pressure
- Single-stage intermittent pilot with continuous retry control system for natural or propane gas operation.
- Right side access to burner and gas controls (when looking into the discharge) with slide-out burner drawer
- High limit safety control
- Control terminal board
- Separate electrical, venting, and gas control access with fully gasketed doors to seal components from the environment.
- Combustion air is drawn completely from outside to ensure that the unit always has plenty of fresh, clean air.
- Since combustion air is introduced from outside, off-cycle vent losses are essentially eliminated, further improving building efficiency.
- Horizontal or vertical two-pipe or concentric venting options.
