What do you think

Thursday I stuffed the damper area and sealed off the ss liner with Roxul and stuck some on both sides of the unit not covering up any air ports , I will add the sheet metal to the block off plate shortly. Well I thought I would have to watch out for an overfire more closely because prior to adding the insulation my insert stove top would hit 600 so fast. This is not the case, It seems like more of a chore to get the stove top to 600 post insulation, I can get there as measured with the IR gun just takes more time ( 250 at reload to 600 = 40 minutes or so) I just dont get it but I really like the fact its more of a controlled burn, the unit has great secondaries and Im burning clean with no smoke, I checked the liner for holes or dents and all looks good, my liner is spic and span because I cleaned againe today and the stove acts the same. Could the insert have been drawing in too much air before? , I dont know, but I like it.

With Green's advise i did check the appliance connector, I used a Bic lighter around it and found three spots where it sucked my flame down, I suffed it with Roxul for now and will cement it later. We were unsure if this was the issue. Just wanted to open it up to the forum

Right on Ed! You'll notice a big difference and like you stated, the stove will be more controllable.
