hi guys,first timer and looking for a little help,recently bought the above for $100,read all about scandia here,junk etc,well this unit has not seen more than 10 fires when i bought it,for the first few times we lit it,we were able to get the downstairs front-to-back split ranch up to 64 deg with the upstairs at 68 deg,not too shabby,since then,i am having trouble breaking 60 down-64 up,any ideas would be great,btw,the unit looks exactly like a 325c insert pictured here on another page,only difference is my trim is rippled as opposed to his which is feathered,had a chimney guy come out to inspect and as far as he could tell everything is as it should be,i open the lower damper wide and leave the door cracked an inch until the fire gets going then close the lower damper while leaving the upper damper half open,thanks in advance for any help
