Replacement herringbone back refractory for Heatilator wood fireplaces. Fits the following models:

NOTES:

1. This part measures 23 5/8" W x 22 1/2 H x 5/8" D. 
2. To prevent cracking due to thermal shock, we recommend seasoning the refractory by building relatively small fires for the first few burns, and then gradually working up to larger fires.
