Rinnai EX38DTWN Direct Vent Wall Furnace, 38,400 BTU, Natural Gas, White

The Rinnai EX38DTWN is an EX DT Series ductless wall furnace that burns natural gas and vents directly outdoors through a concentric pipe. It modulates between 13,200 and 38,400 BTU/h and comes in a white cabinet, suited to zone or supplemental heating or to working alongside an existing heating system.

Modulating control matches burner output to the heat the room calls for, which saves energy. A programmable thermostat reads in Fahrenheit or Celsius and responds to temperature shifts under 1 degree. The control panel can be locked against unintended operation, especially by children, and the cabinet surface stays cool to the touch while running.

Ignition is direct electronic, power is 120 V AC at 60 Hz, and gas enters through a 1/2 in. FNPT connection. Built-in self-diagnostics help a technician pinpoint faults during service. The cabinet measures 26.40 in. high, 36.63 in. wide and 12.60 in. deep and weighs 108 lb. Heated area depends on climate and where the unit sits in the home, and professional installation is recommended.
