The Direct Comfort GDS8 Gas Furnace provides effective home heating at an affordable price. Energy efficiency is key to controlling the cost of heating your home. This furnace's 80% AFUE rating means 80 cents of every $1.00 of heating energy expense warms your home. Some older central heating systems rate at 60% AFUE, meaning only 60 cents of every $1.00 of heating energy expense warms your home. The remaining 40 cents is lost energy wasteful and expensive. The heart of any furnace is the heat exchanger. Our aluminized-steel tubular heat exchanger has been tested to industry standards. Your Direct Comfort GDS8 Gas Furnace uses a multi-speed blower motor and sound- isolated blower assembly to reduce the noise levels common in other furnaces without these features. Add an insulated, heavy-gauge steel cabinet and the result is quiet comfort. The Direct Comfort GDS8 Furnace models are designed to minimize nOx emissions.

Standard Features:

  • Dual-diameter tubular heat exchanger
  • Single-stage combination redundant gas valve
  • Norton hot surface mini-igniter
  • Quiet multi-speed direct-drive circulator blower motor
  • Furnace control board with self-diagnostics and low-voltage terminal block
  • Quiet single-speed, induced-draft blower
  • Certain models available with low NOx emissions

Cabinet Features:

  • Foil-faced insulation lines the heat exchanger compartment
  • Factory sealed to achieve 2% or less leakage rate at 1.0 inches water gauge external duct static pressure
  • Designed for multi-position installation
  • GMS8 and GHS8: upflow, horizontal left or right
  • GDS8: dedicated downflow
  • Coil and furnace fit flush for most installations
