I'm doing a new install of a pellet stove. After 7 years of using my Englander in a 1972, 14X70 mobile home, we replace it with a 2012 new modular home. We moved in on Christmas of 2012. I didn't hook pellet stove back up right away. When we placed order for new home, we had the heating system upgraded to the highest efficient system they had. It was a $1200 option, so we gave that a go for awhile. It did very well! Cost me about $1500 a year to heat verses using heating system in old mobile home, which cost damn near $4000 a year to heat. That's why I installed a Englander stove. It turned out to actually be my primary heat in mobile home, so after initial investment, which paid for itself the 1st year, it was just a 3 ton purchase of pellets ($700), per year. That was a good savings! Heating with new furnace in new home, I kept it at 70 degrees, it was ok, but didn't have that bone warming fell of a pellet stove. So now I'm installing a pellet stove. Since I have a new home, I wanted a new stove. Sold Englander to brother-n-law, helped him install yesterday and he is cooking away. Hope I don't miss that stove. Anyhow, I have my new install started for new stove and will post pictures when completed. I have a question for my install. When I had the Englander, it was a corner install with a 45 angle off adaptor, to a 2 foot section thru wall thimble to outside, then a clean out tee, 4 foot vertical with 90, then 1 foot section with termination hood. My new stove (USSC stove), is going to be a parallel to inside wall install, which will come straight out back thru wall thimble to outside. My question is; can I get away with straight out install with termination hood, or do I need that vertical rise. Manual shows either way, straight out or with a tee outside and some vertical rise. I WILL have a oak installed, had it on old install & swear by it, so I will have it on this install. With out that vertical rise, do you think it will burn just fine. Like I said, manual shows a diagram picture of a straight out install, and a diagram picture with a clean out tee and vertical rise. I want to make sure to get the best performance out of it. Do I need that vertical rise outside???
