I tried to get a pair of 6 1/4 inch legs from a f3 series jotul stove to put on my old 602 but they don't fit. The flange on the top of the leg from the f3 series is larger and won't fit. How or what can I use to cut the lenght of the 602 legs?

Bummer. The damper frame in my fireplace is cast iron and the easiest thing I found to cut it with was a plain old hacksaw. After trying three or four hi-tech powered methods. They make carbide hacksaw blade for doing it but in my case plain old hacksaw blades cut the stuff like cold butter and it was the same thickness as Jotul legs.

A little oil helps the blade do the job. If you have a cutsaw, you can get metal cutting blades for it also.
With metal cutting, the most important thing is to have the object held well in a vise or workbench. Otherwise, the blade catches and it is a pain to cut it.

For sure. With the damper frame I had the advantage of a few thousand pounds of chimney holding it in place.
And being madder than hell replacing the oil.
After you cut the legs do you have tested engineered specs to support the reduction to clearances below that stove? If you do not have them then the legs specs or stove can not be modified

engineered air space is designed into the space below the legs. Are you a combustion engineer and can you certify the ramification of modifying the stove? Do you have tested approved data to support the modifications? If not then, you are not qualified to make such recommendations

1. We are qualified to tell folks how to cut metal, just like we can tell them how to split wood.
2. The gentleman did not ask for engineering opinions.
In terms of "generic" older stoves such as this, NFPA addressed the length of legs, with 6" being the MAX height they cover, and they also specify the hearth protection for same....
If I were installing such a stove, and had an inadequate hearth, I would mount a sheet of 24 ga metal suspended on clips 1 or two inches below the stove. This would cut the downward radiation vastly.

Craig is right there is a section that details heart protection and thermal resistance in relationship to the height of the legs or pedestal
The problem here is not so much heat design but engineered free flowing air space is being modified I Can't find In the NFPA or the International Codes ,where IT is ok to modify
engineered designs without data re-engineering and support documentation. In order to meet the listing requirement it has to be installed per manufactures specs
IF they detail how much you can cut the legs,. then cut them to the specified length
what Craig is telling you there are guide lines for hearth protection specified in NFPA211, that you now will have to follow since your designed engineered space under that stove has been altered. What we can't tell you is the effects on the stove performance and safety due to the change in reducing designed air flow under that stove, which will effect the over all airflow around that stove
Really your question should be directed to the manufacturer. AFTER all they are the ones that engineered the leg height and wrote the specs.
OR direct your question to you local code official and ask him if he will accept cutting the legs.
No one here is qualified, to advise you to make stove modifications. No one should be doing so

In some cases, yes.......as a fireplace insert. You have to look at the manual.
In other cases, no - the stove just might have various leg height and style options, and you have to choose one. None is "standard".......I know this is true of most Avalon and Lopi stoves (and others)....
In no case is is OK to place a stove without legs on a combustible floor. I think NFPA shows 2" as the minimum height, and you have to do a fancy hearth setup to get away with that.
Note: this is 2003 NFPA. I have not read 2006-7 NFPA yet, so I don't know the changes, if any.
