Important Information:

Proper clearance and installation are important when replacing stove glass. Allow at least 1/8" of room for thermal expansion. Without sufficient clearance, the glass can expand during heating and break.

Mounting screws and other metal hardware also expand as temperatures rise. Do not overtighten the glass-retaining hardware. Hardware secured too firmly can place excessive pressure on the glass and contribute to breakage.

Ceramic glass should not be substituted for tempered glass on a fireplace door unless the appliance or door is specifically approved for ceramic glass. It should never be installed in a factory-built or prefab fireplace unless the unit is heater-rated and approved for this type of glass. Consult the appliance owner's manual before making any glass-type substitution.

FAQs:

Q: What are the dimensions of the glass?
A: The panel measures 18" wide by 10 1/4" high and is 3/16" thick.

Q: Is this tempered glass?
A: No. This product is ceramic glass intended for high-temperature stove applications.

Q: How much room should be left for thermal expansion?
A: Allow at least 1/8" of room for thermal expansion to help prevent pressure-related breakage as the glass heats.

Q: Should the glass-retaining hardware be tightened firmly?
A: The hardware should secure the glass without being overtightened. Metal hardware expands when heated, and excessive pressure can damage the glass.

Q: Can this ceramic glass replace tempered glass in a fireplace door?
A: Not unless the fireplace door or appliance is specifically approved for ceramic glass. Always consult the appliance owner's manual before changing glass types.
