4. Construction of the Fire Pit Enclosure
x
Use non-combustible materials for construction of enclosure, gas supply and power.
•
Adequate drainage for enclosure must be provided to prevent water damage to fire pit.
x
The fire pit insert should be recessed a minimum of 2” from the top of the enclosure to protect flame
from being blown out.
x
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.
x
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.
Make sure that the structure is level.
x
HPC recommends that the pan lip is recessed on trough (linear), and large round products as
illustrated below.
x
HPC cannot guarantee the pan lip on all of our products will be perfectly flat and will not warp due
to heat.
x
Fire pit insert must be accessible for service.
GAS Key Points:
x
Fire pit must have a gas shutoff on 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.
x
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.
VENTING Key Points:
x
IMPORTANT: The minimum requirement is the enclosure incorporate 1 vent on at least 2
sides (2 vents total) at a
minimum size of 18 sq. inches of total free area each (Example: 3”x 6”
or larger) to ensure that heat and residual gas can escape.
We prefer the enclosure incorporate 4
vents total (minimum 18 sq. inches each side) to reduce the risk of thermal shutdown on the EI
Series- some enclosures may require more ventilation based on material, size and extended use.
Installation of the vents in the mid to lower area of the enclosure is recommended. Failure to
properly vent enclosure may result in the fire pit overheating or explosion. Continuous overheating
could lead to heat damage to internal components. The vent may work as a drain as well when
installed at bottom sidewall to prevent water build up.
x
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.
x
When installing insert inside a non-HPC copper or concrete bowl, ventilation should be below bowl.
If bowl is mounted on top of a column, a 6” hole is recommended to allow gas supply, electrical and
water plumbing to clear.
x
OVERHEATING: The fire pit will automatically close gas valve if temperature exceeds 190º F
inside valve box to prevent component damage. Turn main power to the fire pit off and on to reset.
To correct overheating, ensure enclosure has adequate ventilation - se
