I will be having a PE Alderlea T6 installed to replace my current stove and I have a question about clearances and my hearth. The T6 requires a minimum hearth protection of 48”. I’m unsure of where to measure this on my hearth… (see attached pictures)
Do I measure from the brick to the edge of the hearth?
Or, since brick is non-combustible, do I measure from the (assumed) combustible wall behind the brick? Like in picture 3 below
I ask because, if I’m able to measure from the wall behind the brick, my hearth is exactly 48”. If I need to measure from the outside edge of the brick, then I’m short by about 3” and need to get a hearth extender. This is fine but I’d prefer not to if it’s not necessary.
