Picked up my first stove, a Jotul #3 in great shape, and just got it installed. Any advice or feedback on this stove? Hoping $300 was a fair price. Also, the installation instructions indicate that the rear clearance can be reduced with an optional rear heat shield. Woodman’s Parts is no longer able to source the exact shield. Can I use an HYC Board on the wall, with air gap, to accomplish the clearance reduction? Thanks!
