The Lennox Burn Smart™ Guide

Burn Smart

Smart choices for practicing eco-responsible burning

Advancements in hearth technology at Lennox Hearth Products (LHP) 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.

Burn Smart defined

Lennox has identified a select group of products that will help eco-inclined customers make buying decisions that better reflect their approach to responsible living. To qualify as an LHP Burn Smart product, it must fit within the following criteria:

Leadership in Energy and Environmental Design (LEED)

Developed by the U.S. Green Building Council, the (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 are 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 an 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.”

National Association of Home Builders®
(NAHB) Green Building Standard and Guidelines

The NAHB offers two important tools for builders: the NAHB Model Green Home Building Guidelines and the new NAHB Green Building Standard that has gained the recognition of ANSI (American National Standards Institute). These tools for home building, remodeling and renovation, allow builders to choose the program that best meets their needs. Both programs provide comprehensive resources for builders looking to implement green building practices.

  • Similar to LEED, the NAHB uses a point system to determine green best practices. Points are allotted for hearth products that comply. Among others, these include direct-vent, sealed combustion gas fireplaces, sealed wood fireplaces and sealed wood stoves.
  • There are four different levels of green building available to builders wishing to use the green building standard to rate their projects: Bronze, Silver, Gold and Emerald. At all levels, there is a minimum number of points required.
  • In the NAHB Green Building Guidelines, fireplaces are covered under
    (Section 5.1.3 Minimize Potential Sources of Pollutants).
  • In the NAHB Green Building Standard, hearth products are included in
    (Chapter 9, Section 901.2 Fireplaces and Fuel Burning Appliances).

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 1970s and 1980s).
  • 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.
  • In some areas, local jurisdictions have requirements and additional restrictions about the ypes of hearth products that can be installed.
  • Some pellet-burning stoves and fireplace inserts are exempt from EPA certification, however, our Lennox and Country™ Collection lines contain EPA-certified models.

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.
