We have been burning since late Oct. and have used over 20 cord. Heating large building but not as large as some are heating with less wood use... Have replaced seal on door and have concerns about creosote building up on the damper. Has anyone removed pipes in the bottom of firebox for better air? Has anyone removed firebrick? How much of it? We are having problems getting water temps in the boiler up to 180/5. Using oil boiler to help it keep up. Something seems off- Also....on state of Maine woodstove and woodsmoke website I see they state that the E-Classic is rated at 160,000BTU's over an 8hr period whereas the Central Boiler website states the unit replaces 800 gallons of heating oil per month and has a heating capacity similar to the CL6048 - when looking at the CL6048 it states that it is rated at a max of 500,000BTU. Any thoughts on this? Would appreciate any suggestions for improving my E-Classics performance!
