already installed but was a little head scratchin........the kit i bought for my 25pvdc comes with an adapter that connects to the stove ....and the you use the twist lock pie......what is the best way to attach this to the stove........part of it is single walled so i just slide that over the cast aluminum outlet on the stove and put a band clamp on it........seems a little hokey and prone to leaking but i could find no info on the best way to attach.......any ideas? thanks
