What Is Included and What You Will Need

Installation Notes

Warming Trends requires venting on at least two opposing sides of the enclosure, 18 sq in. minimum each, and at least 84 in. of overhead clearance from combustible structures or materials (June 2026 manual). Never fill the cavity with gravel or concrete, keep the burner serviceable from above, fit a gas shutoff outside the fire feature, and have a licensed gas professional make the connection and leak test. Cover the burner with approved media no more than 1/2 in. above the jets. For New York City addresses, outdoor gas fire features and their gas piping fall under the NYC Fuel Gas Code and Department of Buildings permitting, and propane at residences is restricted by the NYC Fire Code, so the approval path must be confirmed before you buy. Book a design consultation and we will size the burner, plate and gas line.

Frequently Asked Questions

Which size do I need?

Measure the inside of your round or square fire pit. The CFBO140 suits about 18 in., the CFBO180 24 in., the CFBO280 30 in., the CFBO320 36 in. and the CFBO360 42 in.

What does the WATERSTOP do?

It is a Warming Trends fitting that helps keep water and debris away from the valve and gas line. It is included on the CFBO140 through CFBO320.

Natural gas or propane?

Each burner is built for one fuel. Order the version that matches your supply; the two are not interchangeable without the correct parts.

What media can I use?

Fire-rated media made for fire features, such as lava rock or fire glass, no more than 1/2 in. above the jets. Never use gravel, pebbles or river rock.
