hearth extension


Recommended Posts

I have not inspected this house yet but its on the schedule. I dont know what kind of fireplace that is yet or what the fuel is. The floor tile appears to be ceramic but I don't know that for sure either. I do not know the sub floor material but since there is an HVAC register in the floor near the wall I assume its a wood sub floor and structure.

My question is, if this fireplace is a type that requires a hearth, is ceramic tile suitable as hearth material?

Before Mike said gas, I was thinking electric fireplace. They don't have a bottom door usually, just glass and trim. Remote control.

They are the most idiot-proof of all, why I like them. No hearth required.

The heat element is near the top.

That is my guess. Electric FP and vinyl floor.

Then there is this requirement.

R1004.2 Hearth extensions. Hearth extensions of approved

factory-built fireplaces shall be installed in accordance with the

listing of the fireplace. The hearth extension shall be readily

distinguishable from the surrounding floor area

"The hearth extension shall be readily

distinguishable from the surrounding floor area"

Why do you suppose this sentence?

Let's say the entire floor in the room were ceramic which would probably be an approved extension material.

It's a wood burning steel insert. There's no hearth and it's a vinyl floor covering.

That settles it; it's dicked up.

Is that vinyl on a slab or a wood floor? On a slab, a properly sized tile hearth should do it but if it's over a wood sub-floor you need a hearth there that is not only large enough in area it must be thick enough to meet the requirement as well.

you've got enough to punt it to someone to figure that out and fix it.

ONE TEAM - ONE FIGHT!!!

Wow! All this...and John hasn't even done the inspection yet.[;)]

No..did it today and writing the report now.

It's vinyl over a wood sub floor. Nice huh? Chimney cap is rusted real bad and the damper was so loose at the hinges it was a bear to operate.

That rule is to prevent people from walking right into the fireplace and burning their feet. Because anyone dumb enough to have a vinyl floor up against a wood burning fireplace just might do that. [:)]

What Mike said. If there's a wood subfloor, there needs to be a fireproof layer under the tiles.
