Hi guys, I finally bought a regency alterra cs 2400, I am thinking of installing it myself. The guy gave me 2 6x48in dsp chimney pipe and the t pipe to get me started. The guy told me I needed a wall thimble and some other stuff. Upon looking online for a selkirk wall thimble I just could not find a good instruction on how to install it, I am planning a through the wall install. Do I pass a chimney pipe thru the thimble? Please be patient with my ignorance. I have ask a quote from the pro and he was asking $1300 for the labor alone. Thanks again guys for all your help. Sash
