BTU Output for SF1500

 BTU/Hour Output

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.

Recommended Maintenance 

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

  • Inspecting the chimney and termination cap (where the exhaust exits the home) for blockages, build-up or debris, and removing any obstructions
  • Inspecting and cleaning the glass, doors, fronts and surrounds with a non-abrasive cleaner
  • Removing ashes into a sealed container until disposal, and inspecting the fire grate
  • A certified hearth professional can help clean the chimney, and inspect all other fireplace elements. Plan to have a local professional clean/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.
