Well, it took almost a week from getting the Blaze King 1107 in the house and having the first fire. Decided against the single wall connector pipe, and it took a number of days, and three separate shipments, to get all the double wall pieces I needed. Ordered two 45 degree elbows in the first order and one came in damaged. Got the double wall from Hart's Hearth and they were great to deal with. Every order was received within 48 hours and they had no qualms replacing the damaged 45 elbow. In a previous post, I expressed alarm regarding a change in the manual for the Blaze King where they were now recommending double wall pipe and at least a 36 inch vertical rise from the top of the stove. I wrote them an e-mail last Sunday night and at 9:00 am the next morning I received a telephone call from Chris at Blaze King. Now, there is a three hour time difference from Charlotte, NC and the west coast. That means it was 6:00 am there when he called. (I'm still waiting on a response from Vermont Castings regarding a question I posed to them over eight weeks ago! Of course I'm not expecting a response now and nor do I care, as I now have a Blaze King that is heating the entire 1500 sq. ft. house [ranch] and keeping all areas at or above 75 degrees). I do use a small 10 inch plastic fan located in the upper corner of one door way to get heat circulated to the back bedroom and bath. After my initial fire I had a few operational questions and called Blaze King. They had someone on the phone with me within three minutes. Just want to say that I am extremely pleased with the Blaze King, the manufacturer, and Hart's Hearth. Highly recommend both.
