This is a new venture for HPC. We were looking for another avenue to get information out to our dealers and distributors. Whether it is technical, catalog updates or some information you may just find useful.

Tech Talks - Gas Fire Pit Clearances

What is the purpose of proper clearance for a gas fire pit?

In today's HPC Fire Inspired™ Tech Talk we are going to talk about the proper clearance to combustible needed when installing a gas fire pit. A combustible is any flammable material that could be seriously damaged by the flame.

HPC looks at clearances two main ways: horizontal and overhead, as well as two BTU ranges: 200K< and 201K-400K. Here are the following HPC recommendations:

  • Standard Burners up to 200K< BTU
    1. Horizontal Clearance – 36" edge of burner pan to any combustible
    2. Overhead Clearance – 84" from top of fire pit enclosure to ceiling AND must have 2 open walls
NOTE: You must meet both of these criteria


  • Standard Burners 201K-400K BTU
    1. Horizontal Clearance – 48" edge of burner pan to any combustible
    2. Overhead Clearance – NO OVERHEAD STRUCTURES

Another clearance that HPC highly recommends your fire pit adheres to is the following:

  • There should be a 2" minimum clearance from the bottom of manifold or valve box to grade

If your gas fire pit adheres to these Clearance guidelines, as well as the guidelines in the previous two Tech Talks (Ventilation and Drainage), you will be able to enjoy safe and worry free fire experience!

Check back next week when we talk about fire pit gas lines!
