Replace Heatilator EC42 With Better System.

[mmmike]

Hello everyone.
My wife and I are purchasing a home next month that has a wood burning Heatilator EC42 factory fireplace in it.

We want to be able to install some kind of wood burning unit that will supplement the 1800-2000 square feet of living space in the home (currently heated with propane).

After doing hours of reading online, I'm not convinced on what we should do.

The Heatilator manual shows the use of double walled 8inch pipe UL 127 which i understand to be rated for lower temperatures, so my thought was to drop a 6 inch chimney liner down it and select a proper fireplace or insert.

Put after reading about inserts, I'm don't know if they have to be used with masonry fireplaces only. Then I started reading about Zero Clearance fireplaces and now I'm totally lost.

There must be thousands of houses with this same exact set up, but I can't find a definitive path to quality heat!

I'm attaching a picture of the current fireplace for what it's worth.

Any thoughts or ideas of how I can fit/replace a new heat source that would actually save me some money?
Mike

You are rightfully confused as what you are trying to do is kind of a grey area in the UL-listing. Most ZC fireplaces do not allow the installation of a fireplace in them unless they have specifically tested together. On the other hand, quite a few fireplace inserts have in their UL-listing that they can be installed in a ZC fireplace. It is essentially up to the local code authority, the home insurance, and the homeowner whether they ok the install or not. I feel, a better and safer way of using the existing fireplace is to put a hearth-mounted, rear-vented stove in front of it and run a liner down the chimney and connect it to a short horizontal run from the stove. The height of the fireplace opening (measured from the hearth) and the depth of the hearth will be critical for that kind of installation. While it will take up more space, you will also get additional benefits besides having a safer install: More radiant heat, often the ability to put a larger stove in, a cooking surface during power outages, and no need for a blower.

I have a superior BR42 with a Jotul 350 insert in it. The BR42 is a prefab zero clearance.

Some heatilators allow inserts but i cant find anything in the instructions for yours allowing it and this statement means at least how i look at it that inserts are not allowed in your unit

And rsnovi you may have an insert installed in your fp but superior is very clear about whether or not it is allowed.

My insert is in a Heatilator A36R, I believe, and it works great. It was installed by a local reputable stove shop. We had a Quadrafire in a zero clearance fireplace in our last house. I would consult your local stove shop. Get the biggest one you can.

The manual for my insert says this:
"The factory-built fireplace must be listed per UL 127 or ULC S610."

The manual for your zc fireplace says this:
"This fireplace system has been tested and listed in accordance with UL 127 and ULC-S610 standards, and has been listed by Underwriters Laboratories Inc. for installation and operation in the United States and Canada as described in this manual."

Consult your local stove shops.

This does not say it can't be done in my interpretation. It says not to install unless specified. My dealer sells both Jotul and Lennox who now own Superior.

He verified with both manufacturers that this was an acceptable install.

Enough of this. It's sounding like the old days of Elk's intractable dogma. We're here to help and inform, not to dictate. If the stove manual, your inspector and insurance is ok with the installation, then approval is documented.
