Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

If you plan to put a fire pit on a grassy area, be sure to put compacted paver sand down first to help level out the ground and add better heat protection. If you’re placing a fire pit on hardscaping, like a concrete patio, consider placing a fire pit mat down first. This can add more protection from the heat and also protect the look of your hardscaping if you choose to remove the fire pit in the future.

There aren’t many problems with fire doors except that they slow down or cut off ventilation at the higher rating levels. For this reason, work with a professional to ensure you have adequate ventilation throughout your house or workspace. The sealing around a fire door is meant to allow for a specific amount of ventilation and will need regular inspections to ensure adequate airflow.

However, you should practice proper pellet stove maintenance, like cleaning the burn pot before each use, deep cleaning the unit at least once per year, and running the fan when the stove is lit.
