Broan, America’s largest manufacturer of residential ventilation products, is the exclusive provider of range hoods that interlock with the Broan Automatic Make-up Air Damper, a solution to meet the new International Residentail Code (IRC) provision concerning make-up air.
| The range hood is the most powerful exhaust fan in the home pulling between 100 to 1200 CFM of air out of the house. As we learned from 8th grade science, every action has a re-action thus, when the air is sucked out by a range hood, the same amount of air is pulled back in.”In order to decrease energy costs more homeowners than ever are weatherizing their homes. Unfortunately, in today’s ‘tighter’ homes, natural ventilation is drastically limited and fresh air is not able to flow in and out of the home, causing an increase in indoor air pollutants and allergens.” says Brian Wellnitz, marketing manager, kitchen ventilation, Broan-NuTone®. |  |
| The Broan line of make-up air dampers removes the unnecessary energy cost penalty from the equation. |
This in combination with an increase in range hood power has the IRC concerned that a large back draft of air through water heater flues and wood buring chimneys will bring carbon monoxide into the home every time the range hood is activated. To address the problem, the 2009 IRC provision requires all range hoods with a blower greater than 400 CFM must be accompanied by a make-up air damper.
In response to the new code, Broan is offering 6 series of Broan range hoods and three series of BEST® range hoods capable of interlocking with the Broan Automatic Make-up Air Damper. Without this combo solution for meeting the IRC code, builders, contractors, remodelers and cabinet installers would be required to install two separate products that require separate wall switches for the damper and hood.
The Broan Automatic Make-up Air damper is unique in that it only operates when necessary. By exclusively providing make-up air when a kitchen, bath or whole-house ventilation product is running, the damper helps prevent homeowners from superfluous and expensive energy usage. The damper equalizes air intake and exhaust, establishing the ideal balance in air pressure levels for proper ventilation fuction and increased energy savings.
