- Not included: the block fire pit, vents and stone
- Required: venting on at least two opposing sides of the enclosure, such as the Warming Trends VENTBW vent kit

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 plan the block layout, venting and gas run.

Frequently Asked Questions
Will it fit my block fire pit?
It is made for round or square block fire pits with a 29 to 31 in. inside opening. Measure inside the wall before ordering.
Are vents included?
No. Add two vents on opposing sides, 18 sq in. minimum each.
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.
Can I install this in New York City?
Possibly, but outdoor gas fire features and their gas piping need NYC Fuel Gas Code and Department of Buildings approval, and propane at residences is restricted by the NYC Fire Code. Talk to us before you order.
