Finally installed the (new to me floor model stove) myself yesterday ( with the wealth of information read on this site) First thing I did was to replace the hardwired "heat only" ceiling fire dectector w/ CO2 and heat detector that is adjacent to stove. As far as I can find in the Enviro manual there is no r value required for hearth pad. Just ember protection (I assume). I used a grey epoxy slab that is used for school science room countertops. Chemical and heat/fire resistant. Actual stone or slate would have been lighter weight LOL but the price was right ... FREE. Not crazy about grey but will replace w/ black in future. I decided to go with the ICC Excel Pipe and the built in OAK. Nice stuff. No smell of smoke.Install once and done. I did pitch the pipe up and out (per Smokey the bear ). I had constrictions w/ hearth footprint and locations of existing wall studs and I really needed the vent to protrude non wind ward side (left in pic) of house which forced me to have a 45 and a 90. Total I have stove adapter , 45, 90, 12" and the end fitting. I was assured this is OK from stove shop I purchased pipe. No cleanout but i will leaf blower trick and or take apart for cleanings. Another reason I decided to go w/ ICC. And yes I have this running through a tripp lite surge protector. As you can see there are no windows to contend with, I am right over 12" from outside corner outside (left to right) and 42" above cement patio with 8" projection from house. Thinking is if I have issue w/ burn I will add components to become up and out. It is burning nice w/ somersets. I have a friend w/ a Mag that I will adjust but it seams to be running fine.
