REQUIREMENTS
1. Only non-combustible materials should come in direct contact with any part of the fire pit. Underneath area should
be non-combustible or a flat level combustible surface according to the clearances specified in this manual..
2. We recommend using 3/4” black iron pipe; however please refer to the NFPA54 (National Fuel Gas Code) for
proper pipe sizing when exceeding 20-feet in length for fire pits rated above 100,000 Btu’s.
3. Determine the size of the round or square fire pit you are preparing to install (Refer to page 3).
4. You must provide a round or square opening out to place the fire pit into the non-combustible enclosure.
Do not exceed the maximum opening from Table 1, dimension B.
5. Follow the local code requirements for the gas type being used. This fire pit should be installed in accordance with
local codes and ordinances or in the absence of local codes, with the latest National Fuel Gas Code, ANSI Z223.1
NFPA54 or CSA B149.1, Natural and Propane Installation Code in Canada.
6. Fire pits create high temperatures, it is very important to have any combustibles at a safe distance.
7.
CAUTION: A minimum of 18 square inches of cross ventilation (per side) is required to keep the enclosure
dry.
8. These products are designed for outdoor use only. Not approved for any indoor use.
9. This fire pit is designed to have lava rock completely covering the spur burner, so that the burner is not visible. Do
not cover more than 1” above the top of the covered burner. When purchasing lava rock use 1” diameter as a base
to fill the burner pan.
10. Gas lines and fittings must be installed in to the non-combustible structure. All gas connections must be leak tested
before installation of the fire pit. Soapy water leak detection is required before regular use of the fire pit.
11. Do not use material that will absorb moisture over time and will not release this moisture quickly. Moisture can boil
in this material and can rapidly break apart and cause damage or personal injury.
12. Never leave any other combustible material on top of the fire pit. This could cause unsafe operation of this system
and damage to the component that will not be covered under our warranty.
13.
Ensure proper water drainage is also incorporated into the fire pit enclosure.

INSTALLING KEY VALVE
The key valve contents: 1- key valve, 1- key and 1- flange. (See figure 4). The valve requires a 1¼” round clearance hole
in the non-combustible enclosure wall. See the instructions supplied with the key valve for more specific details. Note: Be
sure to leak test all fitting before operation. Figure 5 shows an example of a typical installation.
