2) Selecting the Location
WARNING: All fire pits, match lit kits, spark ignition, safety pilot and electronic ignition systems are designed and intended for
outdoor use only.
WARNING:All fire pits must have a gas shutoff on the outside of the exterior of the fire pit to allow for emergency shut off and
maintenance.
WARNING: Select a location where the fire pit can be attended during operation. Never leave an operating fire pit unattended or
by someone not familiar with its operation or emergency shut off locations.
WARNING: Both children and adults should be alerted to the hazards of high surface temperatures and should stay away to avoid
burns and clothing ignition.
WARNING: Young children should be carefully supervised when they are in the area of fire pit.
WARNING: Clothing or other flammable materials should not be placed on or near fire pit.
WARNING: Fire pits create very high temperatures - Combustibles must be located far enough away that there is no risk of
ignition.
IMPORTANT: It is recommended that material such as granite, marble or other dense stone be kept away from heat and
especially flame due to risk of cracking. Manufacturer is not responsible for damage.
Fire Pit Clearances – See Figure 1 On Last Page Up to 200k btu
Under Valve Box When Applicable For Drainage 2”
Sides Surrounding Fire Pit From Structure or Combustibles 36”
Overhead Clearance Above Product 84”
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.
3) Construction of the Enclosure
WARNING:All fire pits must have a gas shutoff on the outside of the exterior of the fire pit to allow for emergency shut off and
maintenance.
WARNING: Use non-combustible materials and construction for gas supply, power and enclosure. A metal outlet box should be
used inside the enclosure for electronic ignition models.
WARNING: 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.
WARNING: 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.
WARNING: The fire pit assembly should be recessed a minimum of 2.25” from the top of the enclosure to protect flame from
being blown out. Some areas may require more- 4 to 6” is not uncommon.
WARRANTY REQUIREMENT: 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. For electronic ignition models the control/valve box must be above grade
with adequate drainage to prevent water damage to the controls inside the box.
Make 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. HPC
cannot guarantee the lip on all of our products will be perfectly flat and will not warp due to heat.
IMPORTANT: Product must be accessible for service.

Keep fire pit covered at all times when not in use.
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.
Keep any debris out of fire pit- clean as needed.
Ring Cleaning: (1 x YR) If flames exhibit any abnormal shapes or behavior, or if burner fails to ignite properly, then
the burner holes may require cleaning. The appliance can be cleaned by carefully removing the media to allow access
to burner. Use a brush to carefully remove dust, spider webs, and loose particles from
base, logs, and fire ring itself. If evidence of damage, fire ring must be replaced with
fire ring specified by manufacturer.
