I have a Englander 49-TRCPM. I've had it for about 3 months. Lately, it's been going out in the middle of the night. It runs 24-7 and never does this during the daytime. I'm consistent about my daily and semi-weekly maintenance. I haven't burned a whole ton yet so I haven't preformed the leaf blower trick yet. I don't have a lazy flame or a performance issue, but I wake up in the morning to a full pot and no fire?? Any ideas where to start looking?
