Section 3 Installation Detail
3.1PREPARATION
The fire feature will require both gas and electrical power. Make sure gas and electricity is turned off
before installing pipes and wires. Install the control panel and gas piping as shown in Figure 1: Natural
Gas, Figure 2: Propane Gas.
Note: Piping and fire bowl/ fire pit construction is different for natural gas and propane gas. Internal gas
lines must be clean and free from any dirt, debris, or contamination.
1. The gas piping and electrical conduit must be installed underground between the control
panel/gas meter and the fire feature. Please consult with a gas professional for proper gas pipe
and fitting sizing. Using smaller piping over long lengths will result in a diminished flame due to
pressure drop/piping resistance.
2. Maintain good piping practice by keeping pipe length and elbows to a minimum to eliminate
unnecessary pressure drops. IMPORTANT: Corrugated flex gas lines should not be used
underground as permanent piping. Rigid pipe should always be used for permanent installation.
3. The gas piping must be reduced to 3/4″ pipe at the fire feature with the means to shut off the
gas supply from the gas meter.
4. Install a ¾” to 1/2” reducer at the fire feature “stub-out” riser. The gas and electric risers should
not be more that 3” to 4” above the installation surface.
5. Install the 1/2” flare to ½” NPT fitting into the reducer fitting/pipe. You may place a manual shut
off valve between the elbow and the reducer for future maintenance. Test gas piping for leaks
Note: The gas and electrical connection should be located at or near the center of each fire bowl/table.
For the electrical, you will need 2 wires and a ground to the appliance.
6. Install wiring (14 or 16 ga) underground between the control panel and the burner assembly. DO
NOT USE BELL OR SPRINKLER WIRE. Lower gauge wire is not capable of carrying the current
needed to operate the appliance. Follow the wiring diagram in Section 6. The appliance should
be wired to a switch or dry contact on the 120 VAC side of the transformer.
NOTE: A light switch, emergency switch, relay contact, mechanical timer should always be installed on
the 120 VAC side of the transformer in order to operate the fire feature. The 12 VAC side may be wired
as far as 50 feet away from the transformer using 14-gauge wire.
7. Only place your fire feature on a level surface and ensure piping is centered, anchor if not
directly on the ground.
8. Take the 1/2” flex hose (provided) and tighten to the flare fitting from the supply line. Do not
kink or make a tight radius bend on the gas hose as it may restrict the flow of gas.
9. There are several vents and drainage holes in the fire bowl/table which must not be blocked. The
electrical and gas pipe hole is sealed such that water cannot penetrate the coping surface under
the bowl and will flow freely away and out to the edges.

3.2 INSTALLATION
INSTALLATION SHOULD BE DONE BY A QUALIFIED GAS SERVICE PROFESSIONAL.
1. The Burner/pan and control will need to be connected to the gas and electrical lines coming up
from the fire feature. Make sure you have the correct orifices on the pilot and the burner inlet
for the gas you are using. You must use the proper orifices for natural gas or propane gas for
both the pilot burner and the main burner. Refer to Section 3.3 for orifice replacement.
2. Connect the flexible gas hose to the inlet flare fitting on the control box. Using a wrench,
tighten the hose to the fitting to avoid gas leaks. If this fitting is not tightened correctly it will
leak and potentially ignite and can damage the control system.
3. Connect the 12 VAC wires, from the control box, to the electrical wires coming out of the
conduit using wire nuts to secure connections. Link the copper ground wire to the
ground/bonding lug on the control box.
4. Reposition the burner and pan onto the fire feature and turn on the gas to check for leaks.
Installing a control box on a non-Prism Hardscapes fire feature
Be sure to use only approved burners with fire feature as they have been pre-tested and rated
for the input and gas designated on the control box.
1. The burner plate must be cut and fitted for the pilot burner assembly in order for the main
burner to ignite and operate properly.
PILOT CUTOUT
HOLE

2. The main burner must have a flame port directly in front of the pilot for the ignition system
to light the main burner and sense the flame.
3. Take the burner and plate and turn it upside down. Add thread sealer onto the burner pipe
threads with particular attention to the last three threads.

4. Take the control box and install the heat shield onto the pipe. To do this, thread the brass
pipe nut onto the burner orifice as far down as possible. Place the heat shield over the outlet
pipe of the control box and thread the orifice into the outlet pipe until tight. Use a wrench on
the burner orifice to tighten fully. Align the heat shield such that it fully shades the control
box and tighten the brass pipe nut enough so that the heat shield will not move.
5. Now, take the control box and install it onto the burner pipe, thread until fully tightened.
Align box so that the pilot hole is exposed and accessible to install the pilot assembly.
6. Turn the burner plate right side up and insert pilot assembly into the pan cutout with the
pilot hood slots facing the burner.
7. Align the two mounting holes over the two holes on the burner plate. Using the self-drilling
screws, secure the pilot burner assembly onto the burner plate.

8. Turn the burner back over exposing the control box and pilot assembly wires. Refer to the
image below, this is what your unit should look like this far.
9. Take the flexible stainless steel pilot hose and secure onto the 1/4” flare fitting at the control
box. Make sure it is tight but do not over tighten as it may strip the threads.
10. Take each half of the 4-pin connector and join the two halves together. Push the connectors
firmly until the latch clicks into place.
11. Take the ½” stainless steel hose and secure onto the ½” gas flare fitting on the control box.
The other end should be connected and tightened onto the ½” flare fitting located at the
supply pipe stub-out riser.
12. Place the burner and plate back into position on the fire feature.
13. Turn on the gas and test for operation. It may take a few tries to purge all the air from the gas
line.
14. Once the burner lights, turn off the unit and let cool.

3.3 REPLACING GAS ORIFICE
Locate the two orifices, one is at the base of the pilot burner and the other is at the end of the main
burner (see pictures below). Each orifice is meant for a specific type of fuel; Natural Gas or Liquid
Propane.

Section 4 Product Setup & Operation
4.1 SETUP
1. Carefully spread the fire media evenly onto the burner plate, do not overfill. You may cover the
burner until it is not visible but do not cover the pilot hood, see image below.
2. Perform a burn test (see section 4.2), if there are areas on the burner that lack flame it may be
a result of too much media.
3. Turn off the system, allow time to cool before clearing the media where the flames were
absent and repeat step 2
4.2 OPERATION
Turn on the power switch to the unit. After 3 seconds, the igniter will begin to glow red. The pilot burner
will then ignite and stay lit for 6 to 8 seconds until the main burner produces flames. Once the burner is
lit, the ignitor will turn off and the flame sensor will keep the flames going.
Note: Wind gusts may displace the flame away from the flame sensor causing a 7 second system to shut
down and re-start the firing sequence. The system will try 3 times to light. If it still fails to ignite, it will
lock out (turn off completely) and will need to be reset by turning the power off and then on again.
Do not operate in rainy conditions as the flame will not operate optimally.
Always turn off your system when fire feature is not in use and never leave the unattended.
It is recommended to cover your fire feature if it will be out of use for a long period of time.
