We have a heatilator prefab wood burning fireplace and want to change over to a gas unit. We have had 3 estimates. Two companies want to tear out the existing unit; one wants to seal off chimney and vent to outside while the other wants to replace pipe in chimney with coax, insulate chimney, and vent thru chimney. The 3rd company wants to install a gas fireplace insert. We are so confused! From reading online, I notice that most inserts are used with masonry fireplaces. Is it common to install insert in prefab unit? What are pros and cons other than being less money for installation?
Gas Fireplace insert or replace existing prefab with new gas fireplace???

You CAN put a gas insert in a Zero Clearance wood burning fireplace. The problem
will be the size. Most ZC boxes will only accept a SMALL insert unless the manual for
your unit SPECIFICALLY states that SOME interior components can be removed in
order to enlarge the interior space. If it's not allowed, then the better option is to tear
it out & replace it. The size of a replacement will be determined by the existing structure
around the ZC box. If it's in an exterior chase the size of that chase (width & depth) will
be you restrictions. Interior installs are generally built closer to the finished dimensions of
the box & tend to only allow for similarly sized units or smaller.
