The steps listed as WARRANTY REQUIREMENT must be strictly followed to qualify for product
warranty. Warranty will be void if not followed.
1) SELECTING THE LOCATION:
WARNING: COMPLETE FIRE PITS ARE DESIGNED FOR OUTDOOR USE. HEARTH PRODUCTS
CONTROLS CO. MUST BE NOTIFIED OF ANY OTHER USE. THIS PRODUCT MUST BE USED ONLY
IN A FULLY VENTED (DAMPER FULLY OPEN IF INDOORS) AREA AND GLASS DOORS FULLY
OPEN (IF INDOORS).
WARNING: FIRE PITS CREATE VERY HIGH TEMPERATURES- IT IS VERY IMPORTANT
THAT COMBUSTIBLES BE KEPT AT SAFE DISTANCES.
•WARRANTY REQUIREMENT: For installation of 110vac powered control systems, it is
required to install a wall switch or breaker for the fire pit electrical outlet away from the enclosure
to prevent unauthorized ignition of the fire pit.
•WARRANTY REQUIREMENT: The fire pit location must accommodate a gas shut off outside
of fire pit enclosure. The gas line should be a minimum of 3/4” or larger based on fire pit size.
•To enjoy your fire pit, select a well drained location that allows for sufficient clearance from
combustible materials.
•Choose a location that allows easy access for installation and maintenance of the fire pit. Make
sure that trees and shrubbery are well clear around and above 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.
•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.
Wooden or solid surfaces such as granite or marble must be located far enough away that
they do not reach a temperature of more than 100 degrees F plus ambient air temperature.
Example: If surrounding air temperature is 70, the wood surface temperature must stay at or
below 170 degrees F.
Complete Fire Pit with Valve box
Under Valve Box 6”
Sides Surrounding Fire Pit 14”
Above Fire Pit 96”
2) CONSTRUCTION OF THE ENCLOSURE:
WARNING: THERE MUST BE AN ELECTRICAL (WALL SWITCH OR BREAKER) AND GAS
SHUTOFF ON THE EXTERIOR OF THE FIRE PIT TO ALLOW FOR EASY ACCESS FOR SHUTDOWN
OR IN THE CASE OF AN EMERGENCY.
WARNING: ALWAYS USE PROPER MATERIALS AND CONSTRUCTION FOR GAS SUPPLY,
POWER, AND ENCLOSURE.
•WARRANTY REQUIREMENT: The enclosure must be constructed on a stable surface. Make
sure that the fire pit is high enough that the control box is above the grade to prevent water
damage to the controls inside the box. NEVER install a fire pit below ground level. Drainage
must be provided for the enclosure to prevent water accumulation leading to damage to
components in the valve box.
•WARRANTY REQUIREMENT: The enclosure must incorporate (2) vents on at least one
side at a minimum size of 18 sq. inches each (Example: 3”x 6” or larger) to allow heat within the
enclosure to escape from void around valve box. Failure to do so will result in the fire pit
automatically shutting down when internal valve box temperature reaches 175º F. This could lead
to heat damage to internal components. Some enclosures may require more ventilation based
on material, size, and extended use. This vent may work as a drain as well to prevent water
build up in enclosure.
•WARRANTY REQUIREMENT: 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 6” under the valve box for proper ventilation.
•Select materials that are non-combustible in both initial installation as well as over time.
•Make sure that the structure is level. We recommend the use of the installation collar (optional)
that may be mortared into the surround.
3) INSTALLATION OF THE COMPLETE FIREPIT ASSEMBLY:
WARNING: CONFIRM THIS APPLIANCE IS BUILT FOR GAS USED- NATURAL GAS OR LP.
DO NOT USE NATURAL GAS APPLIANCE WITH LP OR LP APPLIANCE WITH NATURAL
GAS. REFER TO LABEL ON THIS APPLIANCE.

•WARRANTY REQUIREMENT: The fire pit assembly should be recessed a minimum of 4”
from the top of the enclosure to protect flame from being blown out. Some areas may require
more- 8” is not uncommon.
•WARRANTY REQUIREMENT: All firepits come with a 13” x 13” sheet of insulation between
pan and valve box to protect internal components from heat damage. This may need to be
trimmed
on smaller enclosures for proper fit. PLEASE USE THIS AT ALL TIMES.
•WARRANTY REQUIREMENT: When filling the pan with lava rock and/or decorative glass,
the instructions on Pg. 5 must be followed.
•Gas Pressure Input: The input should be: Natural Gas- 5~7” W/C; LP Gas- 13 ~ 15” W/C.
Anything above this could damage unit.
•The main gas should already be plumbed to the location of the fire pit area. The 24” flex line
coming from the fire pit should be connected to the main gas line. Tighten the flex line fittings to
the gas supply stub and to the fire pit. Avoid sharp bends with flex line to prevent whistling.
•Turn on main gas supply and check all fittings in and around fire pit for leaks using a leak
reactant, leak detector or soapy water. If leaks are found, shut off gas supply repair leaks and
retest.
•The 3’ power cord can be either tied into the main power supply for use with wall switch or
or plugged into remote receiver to use remotely- POWER MUST BE TURNED OFF TO
OUTLET WHEN NOT IN USE.
COMPLETE FIREPIT OPERATION
WARRANTY REQUIREMENT: WHEN NOT IN USE, THE FIREPIT MUST BE COVERED AT ALL
TIMES TO PREVENT DAMAGE TO ELECTRONIC COMPONENTS.
WARNING: 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 IS SUSPECTED, TURN
OFF THE MAIN GAS SUPPLY AND REPAIR IMMEDIATELY.
WARNING: WHEN FIRE PIT IS NOT IN OPERATION, POWER TO ELECTRIC OUTLET MUST
BE TURNED OFF VIA WALL SWITCH OR BREAKER.
WARNING: NEVER USE ANY MATERIAL THAT IS NON-POROUS AND HOLDS MOISTURE LIKE
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.
WARNING: LEAVES, STICKS, WOOD, PAPER, CLOTHING, FOOD MATERIAL, SHOULD ALWAYS
BE KEPT AWAY FROM THE FIREPIT. MAKE SURE THAT THERE IS NO VEGITATION OR OTHER
OBJECTS OVER THE TOP OR SIDES OF THE FIREPIT THAT COULD INTERFERE WITH SAFE &
PROPER OPERATION.
WARNING: IF LAVA ROCK IS WET, ALLOW FIRE PIT TO BURN FOR 45 MINUTES PRIOR TO
COMING 15 FEET WITHIN FIRE PIT.
Fire Pit Start Up:
Initial Start Up: Several “on/off” cycles may be necessary to purge air in gas lines after system
installation. Normal system operation is for igniter to be powered on, pilot flame ignites, and main
burner will turn on.
Notes: Hot Surface Igniter: Igniter will turn off 30 seconds into the trial if the pilot flame
is not lit. It will turn back on for the final 30 seconds of the 90 second trial for ignition. The pilot valve
will be energized for the entire trial for ignition.
Continuous Relight: If pilot flame is blown out at any time, system will automatically re-light up
to 5 times after power is initially applied. It will then shutdown for 5 minutes to purge area, then restart the
6-step process again.
Normal Operation:
1) Confirm there is no debris in fire pit (as mentioned in warnings) including water.
2) Turn “on” electrical power to firepit outlet and gas to fire pit.
3) Using wall switch or remote, turn “on” firepit- this may take a several cycles to purge any air.
4) Once fire pit has ignited, DO NOT leave unattended.
OVERHEATING: The firepit will automatically close gas valve if temperature exceeds 175º F inside
valve box to prevent component damage. When unit cools below 175º F, the unit will automatically
restart. To correct overheating, ensure enclosure has adequate ventilation- see “Construction of
Enclosure”.
Fire Pit Shutdown:
1) Turn “off” fire pit using remote or wall switch.
fire-parts.com

2) If using remote control, turn “off” electrical power or gas to fire pit.
3) Once fire pit has cooled completely, use appropriate cover to protect fire pit.
Fire Pit Maintenance:
1) Keep fire pit covered at all times when not in use.
2) Keep any debris out of fire pit- clean as needed.
3) Flame Sensor Cleaning of Soot: Remove lava rock, glass and blow out box. Clean flame sensor of
any soot. Be careful not to damage ceramic insulators or hot surface ignition element. Place lava rock
or glass back as explained on Pg. 5.
Fig. 1
Here is some additional helpful information to keep in mind:
Fire Pits Dimensions: Are approximately 12” from the bottom of the valve box to the lip of the burner pan. HPC
can provide drawings if so desired.
Installation Collars are available that can be mortared into enclosure and allow for fire pit to be
easily removed for maintenance. Installation Collars measure as follows:
Fire Pit Size Collar I.D. Collar O.D.
19” 20” 26”
25” 26” 32”
31” 32” 38”
37” 38” 44”
Gas Line Construction: Main fire pit gas supply lines that transition from large ID to smaller ID (i.e. 1” ID supply
line to ½” ID) line will result in more noticeable noise when burner is in operation. This is particularly noticeable
when transition is installed inside fire pit structure. Installer should also minimize long runs of corrugated supply
lines to fire pit. Utilizing smooth bore gas supply (hard pipe) lines, shorter flex lines and avoid steep ID transitions
near interior of fire pit will reduce but not eliminate operational noise. Some noise is normal in burner operation.

Lava Rock & Glass Application
Please follow the instructions below to add the finishing touch to your fire pit.
Remember the deeper your lava rock or glass the more risk of reducing if not smothering
the flame. Particular attention needs to be on the sensor assembly area- if sensor is covered,
this will cause the pit to shutdown due to smothering flame around sensor or shorting out
sensor rod.
Lava Rock Only Application Decorative Glass Application
