I have my new Enviro Milan insert ready to go and picked up my liner kit today. The liner kit was supposed to have a 4" Tee with a 3" takeoff to connect to the back of the stove but it is a 4" takeoff. Now I am sort of screwed, they tried to sell me a 4" to 3" appliance adapter to connect the Tee to the stove but it adds about 6" of depth that I don't have in the fireplace. Then they claim to never have seen the Tee with a different takeoff than the liner connection. Any suggestions or know where to get the Tee I am looking for?
