One interesting aspect of factory built (pre-fabricated) fireplaces is that they are a UL listed and sometimes have very specific requirements for what can and can’t be used.

Today we will talk specifically about fireplace grates for factory built systems. Most fireplace manufacturers design the fireplace grate uniquely for the system, factoring in things such as size, height, and placement to help the system function as intended.

The data plate and/or instruction manual should have the required information of what replacement grate will be needed. Here is one example of a data plate with the grate information below:

I have seen several occasions where a grate has been improperly replaced causing smoke to enter the home or even over firing of the fireplace system! If you ever have any questions, reach out to your local CSIA certified chimney professional or the manufacturer to ensure proper replacement.
