Maintain Chimneys and Flues
New England Gas Company urges you to have a licensed heating contractor periodically inspect your chimneys and flue pipes for safe operation. Chimneys and flue pipes should be checked for soot, residue or any other obstructions that could disrupt the flow of escaping gases and cause improper venting of carbon monoxide (CO).
Maintain Exhaust Vents
High efficiency furnaces, water heaters and other energy-saving appliances may have exhaust vents that exit your building through an exterior wall rather than through a chimney. These vents can become blocked in the winter months by snow and ice, which can affect the safe operation of the appliance. Therefore, please ensure that all snow, ice and other obstructions are removed from your venting systems.
