TABLE OF CONTENTS
NOTE: An exterior lid/cover is not required but highly recommended when the re pit is not in use. Even though re
pits are designed for outdoors they are not impervious to all weather conditions if not protected. See the accessory
page for information and sizes.
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

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)
Description: These re pits are designed to be installed into a non-combustible enclosure. They are a “drop-in” style
system to make installation quick and convenient. Media (not supplied) is required inside the burner pan for operation
(See page 9).
WARNING: Proper clearances from combustible materials must be maintained from all sides, top and bottom of this
appliance. Use the specications listed on pages 4 and 5 for proper clearance to combustibles.
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 product 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.
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 this may prevent proper ventilation. 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 line sizing chart on page 8 as a
reference.
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. Extend the gas supply system using minimum of ¾” black iron pipe or an approved exible gas line from existing
house supply. This can be accomplished by teeing off or tapping into a gas line connection. Install necessary pipe for the
distance required and then install a manual shut-off valve at the exterior house wall. If pipe is to pass through a foundation
or house wall, make sure to re-seal the area around the pipe with weather sealant.
3. The primary gas shut-off (not supplied) will require a ⅜” male ared tting to enable connection of the stainless steel
ex gas line supplied with the re pit (see Fig. 7 page 10).

REV. B Page 7
Drop in Pan - TMSI Fire Pits
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
(two opposite sides) of cross ventilation is required to
keep the components in good working order. Use Fig. 4 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.

PREPARING A NON-COMBUSTIBLE STRUCTURE
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. Determine the size of the re pit you are
preparing to install (Refer to page 8).
3. You must provide a rectangular opening cutout to place the re pit into the non-combustible enclosure. Refer to
Table 1, dimension A.
4. 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.
5. Fire pits create high temperatures, it is very important to have any combustibles at a safe distance.
6. CAUTION: A minimum of 18 square inches of cross ventilation (opposite side) is required to keep the
enclosure dry. See Fig. 4.
7. These products are designed for outdoor use only. Not approved for any indoor use.
8. This re pit is designed to have Firegear Outdoors lava rock or glass media completely covering the burner tube,
so that the burner is not visible. Do not cover more than 1” above the top of burner. Use lava rock a minimum of 1”
diameter as a base to ll the burner pan. DO NOT USE STONE OR RIVER ROCK.
9. 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.
10. Do not use media 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. See Caution on bottom of page 3.
11. Never leave any 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 FIRE PIT INTO AN APPROVED ENCLOSURE

REV. B Page 11
Drop in Pan - TMSI Fire Pits
INSTALLATION OF LAVA ROCK/MEDIA INTO BURNER
PAN
Install lava rock into the burner pan. Ensure the lava rock
is a 1 to 2-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 media directly on 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. 9).
Cover the burner completely with media but do not make
the depth greater than 1-inch overtop of the burner port-
holes.
Do NOT cover the top of the screen hood with any rock or
glass. It must be free an any debris to operate properly.
Fig. 9 Keep screen cover exposed
THERMOCOUPLE ALIGNMENT
It is to important check the thermocouple to enure it is
properly aligned under the screen cover and that it did not
move during shipping. Before lighting visually look at the
thermocouple tip. The tip must be aligned with a port hole
of the burner to ensure proper operation. In addition, the
ignitor tips must be aligned with a port hole for proper
ignition of the gas. See Fig. 8. Note: If the thermocouple is
misaligned remove the screen cover and carefully correct.

FIRE PIT MAINTENANCE
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.
TROUBLE SHOOTING
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 re pit 1. Excess dust/sand material from media may be blocking the weep holes to relieve water.
2. Remove all media and unplug weep holes. Clean or install new media free of dust and dirt.
3. Ensure re pit enclosure has proper drainage for water and proper ventilation to dry out.
4. 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 burner tube hole; tip should be overtop of hole.
2. Ensure thermocouple is not screwed 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.

When converting Burners to LP gas the main burner orice must be kept a minimum of 6-inches away from the burner
connection (nipple) to prevent any back pressure at the LP orice. See Fig. 14 below for details. Note: It is acceptable to
install a 90° elbow, if necessary, to run the gas line the opposite direction (see Fig 15 or 16). A 90° elbow is not provided
with the kit.
All NPT pipe threads must be sealed with approved gas Teon tape or pipe compound.
Check for any gas leaks before presuming normal operation after conversion is complete.
CAUTION: Ensure there is ventilation under the burner to provide fresh air for air shutter/orice.
