Anyone out there have a blaze king ultra. I have burned one for the last 5 winters. Love it, until this week we fired it up and when I close the bypass handle the fire seems to die immediatlly and totally out in about an hour or so. Thinking its probably the catylist. Needs a cleaning or replaced but wanted to see what experience you guys might have. It has 5 winter seasons and I burn 24/7 for about 7 months out of the year, Thanks for any thoughts.
