The Lennox Burn Smart™ Guide

Burn Smart

Smart choices for practicing eco-responsible burning

Advancements in hearth technology at Lennox Hearth Products have produced a variety of options that allow you to burn cleaner and more efficiently than ever before. At Lennox, we call these Burn Smart products. With Burn Smart fireplaces and stoves, you can be confident you are doing your part to burn smarter and more responsibly at home for the good of your environment.

Leadership in Energy and Environmental Design (LEED)

Developed by the U.S. Green Building Council, the Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ provides a third-party certification program for sustainable building. It is the nationally accepted benchmark for the design, construction and operation of high-performance green buildings.

Logo USGBC
  • LEED has established a point system by which building design and construction can be rated to establish “best” practices.
  • Fireplaces appear in the LEED system under the category of Indoor Environmental Quality (EQ).
  • Fireplaces that conform to the requirements of this category would be considered to be contributing to the overall “green” rating of the home.
  • Fireplaces are mentioned in section EQ 2–Combustion Venting.
  • This section awards a maximum of two points to the builder of the home towards his overall rating for meeting the requirements of this section.
  • The intent of this section is to “minimize the leakage of combustion gases into the occupied space of the home.”

NAHB Green Building Guidelines

Developed by the National Association of Home Builders®, the NAHB Model Green Home Building Guidelines are designed to help systemize the green design and construction process for new homes. They provide a comprehensive resource for builders looking to implement green building practices. Debuting in 2005, these evolving and influential guidelines have helped bring more environmentally friendly building concepts into the mass market.

  • Similar to LEED, the Green Building Guidelines use a point system to determine green best practices.
  • There are three different levels of green building available to builders wishing to use these guidelines to rate their projects—Bronze, Silver, and Gold. At all levels, there is a minimum number of points required.
  • Fireplaces are covered under Section 5.1.3 Minimize Potential Sources of Pollutants.
  • The intent of this section is to “minimize the risk of smoke and combustion byproducts backdrafting into the home. Outdoor air is supplied directly to the combustion chamber so that indoor air is not required for combustion.”
  • Six points are allotted for hearth products that comply. These include direct-vent, sealed combustion gas fireplaces, sealed wood fireplaces or sealed wood stoves.

EPA Certification

The U.S. Environmental Protection Agency sets standards for air quality—including limits on the amount of particulate matter (microscopic particles) emitted by fireplaces and stoves. All wood stoves and fireplace inserts manufactured and sold today in the United States are required to be certified by the EPA.

  • All stoves must prove emissions of less than 7.5 grams of particulates per hour (compared to the 42 grams of particulates per hour from wood burners manufactured in the 70s and 80s).
  • All EPA-certified wood stoves and fireplace inserts have a permanent label on the back that bears the name of the United States Environmental Protection Agency.
  • Not all areas comply with these regulations and may have restrictions on the types of hearth products allowed.
  • In some areas, local jurisdictions have requirements about the types of fireplaces that can be installed.
  • Pellet stoves and fireplace inserts are exempt from EPA certification.

ENERGY STAR® Indoor Air Package

Created by the Environmental Protection Agency, the ENERGY STAR Indoor Air Package (IAP) helps builders meet an increasing demand for homes with improved indoor air quality and energy efficiency. These guidelines detail the EPA’s stringent specifications and help progressive builders and homeowners construct ecologically conscious buildings and homes.

  • ENERGY STAR Indoor Air Package guidelines were developed based on the best available science and information about risks associated with indoor air quality problems, and balanced with practical issues of cost, builder production process compatibility, and enforceability.
  • Fireplaces appear in the IAP guidelines under the category of Combustion Appliances.
  • Fireplaces are covered under Section 5.3 of the IAP Specification guidelines.

This section serves to educate consumers and builders about emissions requirements from various agencies and minimizing the risk of unhealthy internal air quality.

This section also includes detailed information about fireplace venting options for “minimizing the potential for spillage or ‘backdrafting’” by complying with specific design specifications.
