BTU Capacity Versus Requirements

The amount of heat produced by a heating appliance is measured in British Thermal Units (BTUs). One BTU represents the amount of energy required to raise the temperature of 1 lb. of water by 1 degree F.

Generally, more BTUs correlate to greater heating potential. However, the amount of BTUs needed to heat a specific area varies, based on climate and home efficiency.

Maintenance

Get the most out of your hearth product by staying up-to-date on basic maintenance and care. Some maintenance activities you can perform include:

  • Inspecting and cleaning the glass with a non-abrasive cleaner weekly
  • Inspecting the firebox, and cleaning and removing any debris with a cloth or stiff brush monthly
  • Inspecting the door and lid gaskets every heating season
  • Inspecting the blower, exhaust path and all venting components for blockages, build-up or debris, and removing any obstructions every heating season

A certified hearth professional can help inspect your venting, and inspect or clean all other needed elements. Plan to have a local professional inspect your appliance annually. And always be sure your appliance is off and completely cooled before performing any maintenance.

Consult the installation/owner’s manual for more detailed information on maintenance.
