TABLE OF CONTENTS
NOTE: This installation instruction covers (2) different ignition systems: Match Light (MT) and Thermocouple
Manual Safety (TMSI) models. Look for your specic section in the table of contents.
All media (i.e. lava rock, lava stones, lava boulders and re glass) has the potential of thermal
spalling. This is a process that may occur when media is wet and moisture gets trapped inside of
the material due to rapid temperature differences. When this happens the media has the potential
to crack or “pop” outside the replace.
WE HIGHLY RECOMMEND COVERING ALL FIRE FEATURES WHEN NOT IN USE
The use of a cover can lessen the impact of thermal spalling; however, heavy rains, high
humidity and the presence of moisture may still cause the media to pop.
ALWAYS USE CAUTION WHEN USING THE FIRE FEATURE
Extra caution should be taken when lighting a replace when heavy rains, high humidity and
moisture are present. Light the replace; leave the area allowing any moisture in the media to
dissipate. We strongly recommend that during this drying out time that you monitor the re feature
from a distance. This drying out period should be no less than 30 minutes. Continue monitoring
the ame from distance to ensure that all popping has ceased before fully enjoying the re.
CALIFORNIA PROPOSITION 65

Firegear Outdoors re pits are constructed and tested to follow the rigid ANSI standards for gas appliances and
manufactured safely providing dependable and certied products. If these re pits are not installed according to the
installation manual (i.e. not providing ventilation, not providing proper drainage, installing re pits below grade or
modifying the existing products from a normal installation) Firegear Outdoors cannot be responsible if the product does
not operate as designed.
Modifying the re pit directly out of the carton will void the warranty and nullify the UL listing it was certied for. Before
you consider creating your own custom design with a certied product ensure you contact Firegear Outdoors to consult
the installation before proceeding. If you move forward and modify a product without consulting, Firegear Outdoors
cannot be responsible if the product does not operate as designed.
NOTICE
WARNING: Proper clearances from combustible materials must be maintained from all sides, top and bottom of this
appliance. Use the specications listed on page 4 for proper clearance to combustibles.
PREPARING A NON-COMBUSTIBLE STRUCTURE
The re pit can be installed on a at, stable surface, away from any combustible materials. Install re pit on any level,
outdoor non-combustible, at stable surface or a combustible oor according to the clearances specied in this manual.
NOTE: Do not place re pit directly on grass, dirt, or rocks as this may prevent proper ventilation (Fig. 3). Ensure proper
water drainage is also incorporated into the re pit enclosure.
HARD PIPING TO FIRE PIT WITHOUT GAS PROXIMITY
NOTE: Refer to the NFPA54 (National Fuel Gas Code) for proper pipe sizing. See gas pipe sizing chart on page 5.
1. Turn OFF gas supply system. NOTE: All gas connections (except for brass to brass) require the following. Clean pipe
threads using either a wire brush or steel wool. Apply pipe sealant to the ttings before making any connection.
BE CAREFUL! Ensure all gas connections are snug, but do not over tighten!
2. The primary gas shut-off (not supplied) will require a ½” male ared tting to enable connection of the stainless steel
ex gas line supplied with the re pit.
IMPORTANT
Installation of Natural or LP gas should be done by a qualied installer, service agency or gas supplier.
This appliance must be isolated from the gas supply piping system by closing its manual shutoff valve during any
pressure testing of the gas supply piping system at test pressures equal to or less than ½” psig (3.5kPa)
VENTILATION FOR NON-COMBUSTIBLE ENCLOSURE
Fire pits are subjected to many outdoor elements such as rain, snow,
wind, heat or cold. A minimum of 18 square inches of cross
ventilation (2 sides) is required to keep the components in good
working order. Use Fig. 3 as guide to assist to incorporate proper
ventilation.

HIGH ELEVATION INSTALLATION
This appliance is listed for elevations from 0- 4500 feet in Canada
and the U.S. If elevation exceeds 4500 feet it may be necessary to
decrease the input rating by changing the existing burner orice to a
smaller size. Input should be reduced 4% for each 1000 feet beyond
the 4500 feet above sea level. Check with your local gas utility for
assistance in determining the proper orice in your location. In some
cases the heating value may already be reduced and downsizing the
orice may not be necessary. Refer to NFPA54 Table E.1.1(d) for high
altitude orice sizing.

Round Flat Disc REV. 1-7-19 Page 7
REQUIREMENTS
1. Only non-combustible materials should come in direct contact with any part of the re pit. Underneath area should
be non-combustible or a at level combustible surface according to the clearances specied in this manual..
2. Refer to the NFPA54 (National Fuel Gas Code) for proper pipe sizing. See gas pipe sizing chart on page 5.
3. Determine the size of the round re pit you are preparing to install (Refer to page 4).
4. You must provide a round opening cut-out opening to place the at disc onto the non-combustible enclosure. Do not
exceed the maximum opening from Table 1, dimension B located on page 4.
5. Follow the local code requirements for the gas type being used. This re 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. Refer to page 4.
7. CAUTION: A minimum of 18 square inches of cross ventilation (per side) is required to keep the inside of the
enclosure dry. We recommend installation of a VENT-KIT-6x12. See accessory section.
8. These products are designed for outdoor use only. Not approved for any indoor use.
9. This re 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 burner. When purchasing lava rock use 1” to 2” diameter as a base to
cover the at disc.
10. Gas lines and ttings must be installed in to the non-combustible structure. All gas connections must be leak tested
before installation of the re pit. Soapy water leak detection is required before regular use of the re 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 re 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 re pit enclosure.

INSTALLATION OF LAVA ROCK/MEDIA INTO BURNER PAN
Install lava rock into the burner pan. Ensure the lava rock is a
1-inch diameter for proper operation. Note: Do not pour Lava
Rock directly from bag. It should be placed naturally and NOT
packed in tight. Loose tting is important to ensure robust ames.
Be sure rocks are free of any excessive dust. This prevents the
burner pan weep holes from being plugged and holding water.
IMPORTANT: Do not place rock over top or under the screen
cover. The screen must be free of any debris to ensure proper
lighting of burner and good ame sense (See Fig. 20).
Cover the burner completely with media but do not make the depth
greater than 1-inch overtop of the burner portholes.
Do NOT cover the screen mesh with any rock or glass. It must be
free an any debris to operate properly.
It is important check that the ignitor probes be properly aligned
overtop of the burner port holes and did not move during shipping.
Use the Fig.19 as a guide. Before lighting remove the screen cover
of the ignition hood to burner and ensure the thermocouple is directly
overtop of a burner port hole. The sparking probes and the
thermocouple must be in the path of a ame to ignite the gas for
proper ignition of the ame. Replace the screen cover and follow the
operating instructions.

FIRE PIT MAINTENANCE - SECTION B
1. The re pit should be inspected and cleaned before initial use at least annually by a qualied eld service person.
2. Any component that is found faulty must be replaced with an approved component.
3. Any tampering or modifying with the re pit is dangerous and voids all warranties.
4. During winter months in cold climates and various seasons operation the re pit may be affected by weather
conditions. It is recommended to use a cover/lid overtop of your re pit to protect it from humid/rainy weather
conditions when not in use. Heavy rains/downpours could affect the re pit operation if not covered; if this
occurs ensure you allow the re pit time to dry out before attempting to operate. NOTE: If a combustible type cover is
used over the re pit when not in use be sure to remove it before operation to prevent a severe safety hazard.
5. Carbon (soot) may build up on the surface of logs (if installed) during heavy use. Sooting may also occur periodically
on the screen of the ignitor hood. To clean, brush off with a dry bristle brush or cloth. Keep soot away from clothing or
furniture.
6. Over time stainless steel parts can discolor when heated, usually a golden or brown hue. This
discoloration is normal and does not affect the performance of the appliance.
TMSI TROUBLE SHOOTING - SECTION B
Symptom Remedy
Fire Pit Won’t Light 1. Bleed gas line.
2. Ensure all gas supply lines are turned ON.
3. Ensure there is not too much media overtop of burner; it can inhibit gas from owing.
Low Flame 1. Ensure the base media is at least 1-inch in diameter and top media is no more than 1-inch over
top of burner.
2. Ensure all shut-off valves and valve is fully open.
3. Check for spider webs inside burner orice.
Water In My Fire Pit 1. Excess dust/sand material from media may be blocking the weep holes to relieve water.
Remove all media and unplug weep holes. Clean or install new media free of dust and dirt.
2. Ensure re pit enclosure has proper drainage for water and proper ventilation to dry out.
3. Recommend to purchase a cover/lid to keep excessive water out of the re pit.
Whistling Noises 1. Check media to ensure it is not too tightly packed around the burner tube.
2. Ensure a non-whistling ex connector is being used.
Fire Pit Won’t Stay Lit 1. Check alignment of thermocouple over rainshield.
2. Ensure thermocouple is not installed too tight into gas valve. It should be nger tight plus a
quarter turn with a wrench.
3. Ensure thermocouple is clean and free of any debris. Excessive soot can be an issue.
Piezo Will Not Spark 1. Ensure battery in Piezo (behnd red button) is 1.5 DCV.
2. Ensure battery is not installed backwards.
3. Check to ensure wires are connected, not pitched or frayed. If a frayed wire is touching any
metal it can ground out and spark where the damage is.
Weak Spark at Ignitor 1. Ignitor probes too far apart or too close together. Must be 1/8” apart for maximum sparking.
2. Check gound tab. Ensure wire is secured to tab and screw and nut is tight. Loose tab is no
ground.
