Select a location with good drainage and allows easy access for installation and maintenance of the fire pit.
Pick a location that allows sufficient horizontal room to enjoy the fire pit while allowing a safe distance from
the heat and flame.
4. Construction of the Fire Pit Enclosure
Fire pit must have a gas shutoff on the outside of the exterior of the fire pit to allow for emergency shut off
and maintenance. The gas shutoff should not be used to adjust flame height.
Fuel line sizing is the responsibility of the installer and must be able to supply the stated maximum Btu for the
product- refer to product label on fire pit.
Use non-combustible materials and construction for gas supply, power and enclosure.
Adequate drainage for enclosure must be provided to prevent water damage to fire pit.
IMPORTANT: The enclosure must incorporate 1 vent on at least two opposing sides (2 vents total) at a
minimum size of 18 sq. inches of total free area each (Example: 3”x 6” or larger). ). Installation of the vents
in the mid to lower area of the enclosure is recommended. Ventilation allows for heat and or residual fuel to
escape. Failure to properly vent enclosure may result in the fire-pit overheating or explosion. Some
enclosures may require more ventilation based on material, size, and extended use. The vent may work as a
drain as well when installed at bottom sidewall to prevent water build up.
The interior void space of the enclosure surrounding the valve box cannot be filled with any material (gravel,
crushed rock, concrete, etc.)- It is a requirement to have a minimum of 2” under the valve box for proper
ventilation and drainage.
The fire pit assembly should be recessed a minimum of 2”from the top of the enclosure to protect flame from
being blown out.
The enclosure must be constructed on a stable surface. The weight of the fire pit must be supported by the
pan and not by any control/valve box.
oMake sure that the structure is level. We recommend the use of the installation collar (optional)
that may be mortared into the surround.
HPC recommends that the pan lip is recessed on trough (linear), and large round products as illustrated below.

enclosure and the ground.
The design of the enclosure shall be such that:
oA non-disposable LP-gas cylinder can be connected, disconnected, and the connections inspected and
tested outside the cylinder enclosure; and
oThose connections which could be disturbed when installing the cylinder in the enclosure can be leak
tested inside the enclosure.
Propane Cylinder:
A worn cylinder may be hazardous and should be checked by your propane supplier. Never use a cylinder with a damaged
valve. Use only a propane supply cylinder constructed and marked in accordance with the specifications for LP gas
cylinders of the National Standard of Canada, CAN/CSA B339, Cylinders, Spheres and Tubes for Transportation of
Dangerous Goods; and Commission, as applicable or the Specifications for LP-Gas Cylinders of the U.S. Department of
Transportation (D.O.T.). This appliance has been designed for use with a 20lb or 30lb size propane cylinder only (not
supplied).
The propane cylinder must be provided with a cylinder connection device compatible with the connection for outdoor
appliances. The propane cylinder must be provided with a shut-off valve terminating in a propane cylinder valve type
QCC1, and a safety relief device having direct communication with the vapor space of the cylinder. The cylinder supply
system must be arranged for vapor withdrawal and the cylinder shall include a collar to protect the cylinder valve. The
cylinder shall incorporate listed OPD (overfill protection device). Do not store a spare LP-gas cylinder under or near this
appliance. Never fill the cylinder beyond 80 percent full.
Use only the pressure regulator and hose assembly provided with this appliance. Replacement pressure regulators and hose
assemblies must be specified by the manufacturer. The regulator supplies a pressure of 11 inches water column to the
appliance and has a QCC1 type fitting. Cylinders to be used with this unit must be supplied with a QCC1 cylinder valve. A
QCC1 cylinder has a positive seating connection, which will not allow gas to flow until a positive seal has been achieved. It
is also equipped with an excess flow device. In order to attain full flow to the appliance, the valve must be in the off
position when the cylinder valve is turned on.
Securing the LP tank:
1. Fasten the L-bracket to the bottom of the propane tank using the nut and bolt supplied. Ensure the nut is tight and will not
loosen.
2. Select location for the propane tank and screw the bracket to the mounting surface. For concrete surface, use a concrete
anchor (not supplied). Ensure that screw is tight so that the cylinder cannot move.
Cylinder Connection:
Ensure the gas regulator has no kinks and is smooth. Remove the cap or plug from the cylinder fuel valve. Insert the black QCC1
regulator nipple onto the QCC1 fuel valve and tighten until snug. Do not use tools. Leak test all joints prior to using the gas
appliance. A leak test must be performed annually and each time a cylinder is hooked up or if a part of the gas system is replaced.
Follow the instructions for natural gas hook-up if the appliance is to be connected directly to a house propane gas supply line.

8. Fire Pit Operation
Before use, be sure to test all gas connections for leaks. Do not use fire pit if there is any evidence of leaking gas. If
leaking gas suspected, turn off the main gas supply and repair immediately.
Do not use the enclosure as a seating area. Wind and gusty conditions will affect the flame in an unpredictable manner. If
conditions exist that are not safe for patrons turn the fire pit off.
Do not use fire pit if any part has been submerged under water. Immediately call a qualified service technician to inspect
the fire pit.
Never use any material that is non-porous and holds moisture such as gravel, pebbles, river rock, etc. This material, when
heated will cause the trapped moisture to boil and fracture unexpectedly. This material is not sufficiently porous to allow
heated steam to readily escape which can break and cause personal injury or damage.
Solid fuels shall not be burned in the fire pit. Leaves, sticks, wood, paper, clothing, food material, should be kept away
from the fire pit. Fire pit is not for cooking. Make sure that there is no vegetation or other objects over the top or sides of
the fire pit that could interfere with safe operation. See clearances in Section 3- Selecting the Location.
If lava rock is wet, allow fire pit to burn for 45 minutes prior to coming within 15 feet of the fire pit.
When fire pit is not in operation turn off gas valve.
When not in use the fire pit must be covered at all times.
9. Maintenance
Any guard or protective device removed for servicing must be replaced prior to
operating the fire pit.
We suggest that our products be serviced annually by a professional certified in
the US by the National Fireplace Institute (NFI) as NFI Gas Specialists.
Ensure gas is shut off and fire pit is cool before servicing.
Keep fire pit covered at all times when not in use and free of debris.
In some areas of the country spiders or insects have been known to build nest and or lay eggs in the venture holes of
the air-mixer for LP units. This can cause fuel to fill the fire feature cavity and result in personal injury or property
damage. Periodical inspection by a qualified service technician of the air-intake is required to ensure your fire feature
performs properly.
START UP
1. STOP! Read the safety information on “What to do if you smell gas” (Pg. 1).
2. Confirm there is no debris in the fire pit (as mentioned in warnings) including water.
