hi everybody. i have 2 choices to run my flue. #1 - direct vent , which would give me great air flow though out the 1st floor. i'm going to seal off the upstairs. the 1st floor is 1,200 sqf. the ceiling in open from the front of the house to the rear. no headers anywhere , just ceiling. so if i put the unit in the corner about 6' from the front door 2 ft from the wall , i should get great air flow with a 265 cfm blower and turn my kitchen fan on low , reverse. the kitchen is in the back of the house. #2 - tie into my chimney. i have a 6'' stainless steel liner. in the basement i have an oil boiler and a wood burner hooked up to T at the bottom. boiler has a barometeric damper , the wood burner has just a damper. been running it like this for over 8 years , with no problems. now the chimney flue is about 8''X14''. the chimney is about a 1/4 in to the house.
lol i was thinking of cutting a hole in it and hooking up the unit there , just to the flue. the unit will blow to a wall about 12' away. i will have to use some floor fans to move the heat. i need your ideas on 1 or the other. thank you
