WARNING:
Proper clearances from combustible materials must be maintained from all sides, top and bottom of this
appliance. Use the specifications listed on page 3 for proper clearance to combustibles.
PREPARING A NON-COMBUSTIBLE STRUCTURE
The fire pit can be installed on a flat, stable surface, away from any combustible materials. Install Fire pit on any level,
outdoor non-combustible, flat stable surface or a combustible floor according to the clearances specified in this manual.
NOTE
: Do not place fire pit directly on grass, dirt, or rocks this may prevent proper ventilation (Fig.1, pg. 3).
Ensure
proper water drainage is also incorporated into the fire pit enclosure.
HARD PIPING TO FIRE PIT WITHOUT GAS PROXIMITY
NOTE:
We recommend using 3/4” black iron pipe; however please refer to the NFPA54 (National Fuel Gas Code) for
proper pipe sizing when exceeding 20-feet in length for fire pits rated above 100,000 Btu’s.
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 fittings 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 flexible 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 ½” male flared fitting to enable connection of the stainless steel
flex gas line supplied with the fire pit (see figure 5 page 6).
IMPORTANT
Installation of Natural or LP gas should be done by a qualified 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
(per side) of cross ventilation is required to keep the
components in good working order.
Use figure 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 orifice 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 orifice in your location. In some cases
the heating value may already be reduced and downsizing the
orifice may not be necessary.
