Enjoy instant warmth plus lower heating costs with a traditional enclosed or fireplace look heater. New glass front "fireplace look" or enclosed vented hearth heaters provide comfort for hard-to-heat areas. Williams vented hearth heaters are designed to give you maximum efficiency, low fuel consumption and quiet operation. Unit comes from factory set up for natural gas. In order to operate on LP (liquid propane), the Williams 8948 LP Conversion Kit must be purchased seperately. Please read this Important Safety Notice.

Standard Features

  • No electricity required for heat ... great during power outages. 
  • Burners engineered for quiet ignition and maximum heat efficiency.
  • Louvered-top design and front grill for improved heat circulation.
  • Built in draft diverter to permit close-to-wall installation.
  • Factory-installed ceramic fiber logs (Fireplace model).
  • Natural and propane gas models (Conversion kit available).
  • "Matchless" pilot ignitor.
  • Automatic temperature and safety controls. Thermostat may be mounted on the wall or on the furnace cabinet.

Installation Note: 

For proper venting, do not attach a 90 degree elbow directly to the draft diverter. It is recommended to attach 2 feet (.6m) of straight vent pipe before an elbow is used. Use 45 degree elbows if possible. Run flue pipe as direct as possible; using no more than two elbows. 


Please note: a thermostat does not come with this unit; you can buy the thermostat separately under part number P32662016. Alternately, any standard millivolt thermostat can be used.
