A Healthy Home Begins With a Healthy Hearth
The American Lung Association Health Houses are built to promote the best in indoor air quality for the health of consumers and thus only allow the use of direct-vent gas fireplaces in their Health House homes.

Direct vent fireplaces will not alter the quality of your room air in any way. Each direct vent fireplace utilizes a sealed combustion chamber that draws all combustion air from outside your home and discards all by-products of combustion back outside.
