I recently purchased a Hampton HI300 wood insert. It is scheduled for installation Friday. I did not take the time to read the fine print prior to my purchase. The salesman said I would need 16" of hearth in front of the door. My 24.5" hearth seemed sufficient. However, upon further review, code now requires 18". Additionally, my hearth is flush with the surrounding floor. This means I need 19.5" of hearth in front of the door. Therefore, my hearth is 3.5" too short. I could return it and get the HI200, but I really think it would be undersized. Also, I might be on the hook for some shipping fees.
Since I want to do this right, I have a couple questions for the experts here.
1. I have what appears to be a grout or mortar hearth. I have an unfinished basement, so I am able to measure the depth. The depth varies from 5.5" - 7.5" (7.5" close to fireplace). If it is mortar, I believe the resulting R value is 1.1 to 1.5. If it is concrete (though I see no aggregate, only sand), the resulting R value is .52 - .71. The minimum I need is .6. DOES THIS SEEM CORRECT TO YOU GUYS?
2. I think the easiest way to comply with code is to install the stove as planned and add some tile around the perimeter of my existing hearth. My floor plus subfloor is only 1.5". CAN I GET A .6 R VALUE WITH ONLY 1.5"?
3. I am considering using the stove for a few months while I figure things out and schedule a weekend to tackle the hearth extension. UNTIL I GET IT FIXED, WOULD I BE CRAZY TO USE THE STOVE? ALSO, IS THERE A BANDAID I COULD USE FOR A COUPLE MONTHS?
Thanks for your help with my questions.
