Regency apparently won't stand behind their warranty for their fireplaces. Fireplace (Classic I1150 Wood Insert) worked great for about 30 days, then fire goes out when door closed. Complained to installer, just get excuses. Finally got installer to come out, they couldn't keep fire going either, another excuse. Excuses range from not building fire right, too warm outside, chimney/flue not tall enough, not to building code. I verified chimney/flue is correct. Called Regency and sent email (reference TICK 16905. Answer was no help, did not answer all my questions. Sent two letters certified mail in the last three weeks complaining. No response at all.
