I am Toronto based, and just installed a new high efficiency furnace (York YP9C 080 model) in November. Later on I smell odor in my house when the heat started. It is more apparent when it is a gusty windy night. I have called Enbridge to come and investigate if there is gas leaking from the pipe. But it isn't. the odor makes my eye dry and my throat feels bitter sometimes. I have checked my vent termination outside of my house; tried to do some diagnostic myself with advice from some friends.
I realize my back yard environmental conditions have been changed since the snow storm last year. My two neighbors have cut their trees down after the ice storm last year. My house is situated at the end of a crescent. The back yard looks as if it is the end of a tunnel. I am not sure if the vent termination is affected by wind gust factor. If is the case, a technician recommended me to move the vent to the other direction inside the house. It can be costly. Will you recommend I use a tee vent so the wind cannot directly impact the force back to the exhaust pipe. I had two nights ago when the wind was really strong, in the middle of the night, I even smell gas but it went away a few minutes later. I am not sure if the strong wind create the force that pressure the exhaust back to the furnace and caused this gas smell.
Please advise if a tee can put on the exhaust pipe can help? or other recommendations can be made?
