hi folks, just got / installed a new quadrafire 3100 steptop. been burning 3 days now and have a few ?s. temps in single digits and below. no problem heating 2200 sq ft wide open house. i see some people post 8-12 hr. burn times. after 6 hrs all i have is a good bed of coals, air shut down before going to bed. seem normal? also when should i reload? i have been mostly playing (as it is a new toy) and burning wide open or very close for about an hour to raise the temp in stove room to 75-78 then shut down to 1/4 open for the rest of day. this seems to maintain a consistant temp. when i have room for a couple of logs, i reload and dont mess with the air.should i let i burn down more? burning mix of hardwoods all dry and seasoned. (so i am told) i have read that you should burn wide open for a bit every week to help clean chimney. if so how often and how long? my chimney is 5-1/2 ft double wall and 7 ft class a. straight up. this unit / chimney seems to work well no smoke, puffs of smoke or smoke from chimney after burning good. thanks in advance for the advice, oneway.
