From doing some searching it sounds like it could be a silent flame stove? Does it say that anywhere? This company made stoves under that name, however, none with that model number.
I can find a manual for the 1661 and 1662 but not for the 1653 like you have.
Unless you can dig up something that I can't, this thing is going to need to be installed by NFPA 211 guidelines,,, if that is OK with your insurance company.
In general, clearances for this were 36 inches, but could be reduced with wall shields that are non-combustible and were left with a 1 inch air space behind them (screw to the wall but use a 1 inch piece of pipe behind the shield going through each screw, or strips of backer board to keep it off the wall). However, I'm not sure exactly what the specs are for a corner installation are without looking them up,,,, but it'd be best to make sure that installing by NFPA 211 guidelines is OK with them before putting much effort into things.
If the corner is 6 inches away from that hardy and the shield now, and both are sitting directly on top of the paneling, then it is NOT safe to operate the wood stove,,,, as that is far too close. There needs to be spacing between the shield and the wall, and even then, 6 inches may be pushing it.
Good luck,
