I'm getting ready to install my new lopi 1750 and im gonna be using sure temp chimney pipe and support box. Im most likely gonna use selkirk dsp doublewall pipe and was wondering if anyone know if ill need a flue collar adapter to make this pipe work? Also is there anyway to connect the dsp pipe to the singlewall dripless adapter? Just wondering cause i already have it as it came with the kit i bought. Otherwise i see selkirk sells a telescopic kit that includes the pipe,finishing band and look lik3 an adapter from class a to the dsp. Any help is very appreciated thanks
