Can I put gas insert into wood burning Heatilator HB42A1?

[cinderellaNJ]

We have a wood burning Heatilator from 1996 that we rarely use (HB42A1) and finally want to get a gas insert. Is the heatilator considered a wood insert? Is the whole thing going to have to be demolished including the marble surround and hearth (floor level hearth-not raised). I was so excited until I realized they are huge compared to the size of the firebox I see. Can the front just sort of be cut out? Was hoping to spend under 5k and probably get a heat-n-glo mid level. I'm in New Jersey. Thanks.

If you have the manual for your zero-clearance wood burning fire place (not an insert), it may tell you if it’s approved for a gas insert & what you can or cannot remove if it IS approved. If you choose an insert & Heatilator says it’s ok, you should not have to change any part of your surround (I. e. stone or mantle).

It doesn't mention inserts in the installation & operating instructions.. it does mention gas logs. Photo of section attached.
