I’ve used it almost 24/7 for almost 5 months a year here in Anchorage, AK since purchased new in ‘92. My complaints would be that the draft is not thermostaticly controlled and the catalyst only lasts a few years even with recomended cleaning. I’m on my fifth now. I don’t have a surface thermometer, but with the catalyst working well the combustor thermometer reads between 800 and 1500 F controlled by setting the front drafts only at the first hash mark. Side draft is always closed except to start fire or raise temp. on cat. if has fallen to low. I fill it about every 4 hours during the day. It has always been difficult to get an overnight burn out of it. It drops below 500 and probably causes some creosote problems with cat. I clean a 1/4” of fluffly deposits from the 18’ flu each summer.
My current problem is it burns to hot with my new condar steelcat combustor. I’ve used the ceramic in the past. I have to keep the front drafts down to a 1/4” opening so the glass air wash doesn’t work as it always has. I’ve had to use box fan to keep the cat thermometer below the to hot mark at times.
