Boiler and venting options
I'm hoping to replace a 1940's coal now oil hot water boiler to natural gas. Looking at the different models offered by the gas company; they are all Burnam. Possible boilers are Series 2 (81% eff - cast iron); ES2 (85% eff - cast iron); SCG (85% eff - cast iron); Alpine (95% eff - stainless steel). I rejected the aluminum boilers because of the age of my system and sensitivity of aluminum to air and rust particles.
Foot thick stone foundation, so if want to use side vent and not chimney for SCG or Alpine, it would be easiest to run through a blocked off small basement windows. But this is close to ground level and has a window above it, so would need to take the vent pipe out and snorkel it up and off to the side to get above snow line and far enough from 1st floor window.
The SCG shows a snorkel vent in its IOS manual, but it goes straight up. Alpine doesn't discuss snorkel vent at all in its manual. Does anyone know if a snorkel vent would be allowed with an Alpine; and can the snorkel be placed at a 45 degree angle for either one of them? If I can't work this out I may have to go with a Series 2 and ES2 and chimney liner.
Thanks for any help!
