HPC 18" Square Bowl Pan Push Button Flame Sensing Fire Pit

HPC 18" Square Bowl Pan Push Button Flame Sensing Fire Pit

The HPC 18" Square Bowl Pan Push Button Flame Sensing Fire Pit is a drop-in gas burner for a custom fire pit: an 18" x 18" 304 stainless steel square bowl pan with a 12" Penta burner, rated at 65,000 BTU in HPC's price list (90,000 BTU in HPC's drawing) with push-button spark ignition and a flame-sensing pilot. It needs no electricity (the spark igniter runs on a AA battery). Model numbers are FPPK18-SQBL-FLEX-NG for natural gas and FPPK18-SQBL-FLEX-LP for propane on fixed piping. A small tank version (FPPK18-SQBL-FLEX-LP-ST) runs from a 20 lb or 30 lb propane cylinder at 65,000 BTU.

It is certified for outdoor use.

• HPC Black Lava Rock Nuggets for Fire Pits - 1/2 Cubic Foot (657): only deep enough to cover the burner

Specifications

Dimensions

HPC's price list gives 65,000 BTU for this model and its drawing gives 90,000 BTU, so contact us to confirm before you size the gas line.

The pan drops into the opening and rests on its 1-1/2" lip. HPC's drawing gives a recommended enclosure size but no separate cutout size, so check the drawing with your installer and contact us before you cut.

Installation Notes

• Outdoor use only, installed above grade where water drains away.
• Set the pan at least 2" below the top of the enclosure to protect the flame from wind, and let the pan carry the weight, not the valve.
• Venting: an enclosure needs at least two vents of 18 sq in each on opposite sides. In a copper, concrete or metal bowl, use two 9 sq in vents on opposite sides, or raise the bowl at least 3/4" off the surface with a 6" hole in the bottom.
• Leave at least 2" below the valve for air and drainage, and don't fill the space around it with gravel, rock or concrete.
• Clearances: 36" from the sides to structures or combustibles (12" to noncombustible materials) and 84" overhead.
• Put a gas shutoff on the outside of the enclosure, and keep the fire pit covered when it isn't in use.
• Small tank version: keep the propane cylinder in its own ventilated enclosure at least 54" from the fire pit, secured with the supplied bracket, and use only the supplied regulator and hose.
• Use only lava rock or decorative glass over the burner, and don't cover the vents of the pilot's blowout box. Propane installs with glass must be checked for back pressure with the media in place.
• The gas connections should be installed and leak-checked by a qualified gas installer, and checked again every year.
