I love the look and functionality of the Progress Hybrid. We have an old (1980) wood stove that is having problems and needs to be replaced. The hearth it is sitting on is 54" wide. The Progress Hybrid would be a perfect fit for us except that the PH is 30.5" long and per the installation instructions, the hearth needs to extend 16" on the door side and 8" on the other, for a total length of 54.5" (1/2" longer than my existing hearth). Could a 1" wide tile border be added to extend the hearth dimensions? I've read that you can also raise the hearth to increase the effective clearance dimension (e.g. if the hearth is raised 6", then the hearth would only need to extend out 2" on one side and 10" on the door side (though 10" on each side might be preferable for aesthetics). Any thoughts on these options or other ways to address this?

What’s that hearth made of? Can you extend it just in the loading door side with the same material? Or maybe just lay a piece of steel on that side as an extension? Maybe even a hearth rug?

Cool looking old stove!
 
It is flagstone on top, the house was bought with the hearth in place, so I don't know what is below that. The flagstone is in large pieces, so I think adding a small section may look odd, thus my idea of just adding a border of tile (possibly composed of flagstone material) might add a non-combustible surface and also a finished look. I'm not sure what would need to be done to bring that to code however. I may need to have a Hearthstone dealer come out to take a look at it, hopefully they can give me suggestions or advice on this. I'm not sure a hearth rug would meet code - my understanding is that it must be more permanent, thicker and not a possible tripping hazard.
 
Personally, I would cut out as much of the wood floor around that hearth as you need to achieve clearance and add a border of steel flat bar on all three sides flush with existing floor and hearth. You can buy flat stock from metal suppliers in whatever thickness you need to match the floor and would just need to make sure any gap between the steel and stone was adequately sealed off to maintain fire proof-ness. There are also finishes and techniques to "age" the steel to make it fit the aesthetic more appropriately.
 
I know this thread is a couple months old, but as a progress owner, i wouldn't lose a minute of sleep if my hearth were half an inch narrower. The heat is not a factor that far out and on the door side the extra width is just for ember protection as far as I can tell.

The biggest concern for radiant heat is right were the stove pipe connects to the stove. My wall was getting uncomfortably hot even with double wall stove pipe before I added a heat shield.

Thanks Barnacle Bob. I don't really have much of a concern regarding the hearth either - it is just code per the manufacturer and my installer says we need to follow that...so...I went ahead and installed 4" of tile around the existing hearth. It actually looks much more better and only took a few hours to put in. So...problem solved, now just getting the stove hooked up and some tile put up around the larger entry hole for the double wall stove pipe that we are putting in. A little too late for this heating season, but all ready to go for October!
