The Importance of Proper Venting of Orphaned Water Heaters
The importance of proper venting of gas appliances cannot be understated. With the increased efficiency of today’s furnaces and water heaters, venting into older masonry chimneys designed for low efficiency furnaces and water heaters, can create unsafe conditions. In many older homes, new high efficiency furnaces are being installed which no longer use the old masonry chimney, leaving the orphaned water heater to vent into a flue that is over sized. This condition can result in exhaust fumes entering teh home each time the water heater is used. For more on this we have attached a report from WSSC.
