Buderus GB 142 & GB 162

I am getting conflicting information, I am hoping someone can help. My understanding was on both the GB 142 & GB 162 models, you could run 100 ft of vent and 100 ft of exhaust(except for the GB 142/60 - which I believe is 60 ft) obviously taking into account elbows, 45's and concentric vent kit. I have been told this morning by my supplier that this only applys to the GB 142 15, 30 & 45. When you go to the 162 series you can only use 50ft of vent and 50 ft of exhaust. Could anyone advise me? For obvious reasons this could cause some real problems. I called Buderus Tech again this morning and they say it is definately 100 ft each. Can anyone clarify for sure.

Thanks in advance.

Go to the

Installation manual for the boiler. If it is wrong then the manufacturer needs to address the issue not you. http://www.buderus.us/files/201004161718400.7746800103_GB162_Installation%20Instructions_en_2-2010.pdf

Vent Length

Charlie hit the nail on the head and I read it as to not exceed 100' for either the intake or exhuast. I don't read it as 120' for the exhuast and 80' for the intake. It specifically states 100' is the max for both.

Thanks guys. This is the newest manual I got from Buderus yesterday, it clearly states that it is 100 ft each - I guess my supplier is mistaken.
