The non cat intrepid, is it a pre 88 1302, with the brick baffle in the back as a secondary combustion chamber or a newer non cat model 1640 with no griddle, and gas burner tubes in the top?
VC made several different non cat intrepids. Pre 88’s have a 3 brick secondary combustion chamber, when ya close the damper the smoke runs thru it and burns.
The 1640 had no griddle, and gas burner tubes in the top and more complex air/smoke system.
Then there is the cat models which are pretty much the same, griddle, damper, cat assembly.
any of them work fine but the 1302’s are put together much more simply, the internal parts just interlock together and they are easy to clean and maintain.
The cat models have all those internal plates bolted and calked into place and taking one apart is not fun.
The 1640’s with the gas tube assembly is no picnic either.
if you have a 1302 in really good shape, be nice to it, it should last a long long time.
You can totally strip a 1302 down inside and reassemble it in no time, and all the seams can be checked and recalked from the inside easy.
