Project planning · Gas fire pits

Plan more than the flame.

Coordinate the kettle, gas supply, lifting, burner support and controls before your installer starts work.

Use this guide to prepare a project brief with Grove and your qualified gas installer. Installation and service must follow the manuals supplied with the actual burner and ignition, local requirements and the approved kettle layout. An outdoor fire feature needs space for heat, ventilation, drainage and maintenance as well as seating.

Identify your burner and ignition first

Grove’s current CROSSFIRE 2.0 fire-pit packages have these burner inputs. Give your gas contractor the exact fuel type and model from the order, not simply the kettle diameter.

4FT290,000 BTU/hr
5FT360,000 BTU/hr
7FT450,000 BTU/hr

Grove supplies the Platinum 24V automatic ignition system. This guide’s electronic controls and shutdown discussion refers to that system. It is different from Warming Trends’ basic battery-powered Push Button spark kit; a basic spark button is not a substitute for Platinum’s automatic control. Confirm the supplied model and approved burner capacity with the installer. Compare manufacturer ignition systems.

Plan delivery, lifting and a level setting

Understand the shape

A rounded bowl needs a stable seat.

The lip can be level while the underside stays curved. These sections explain support principles; the pictured cradle is not a drawing of a supplied Grove stand.

Rounded kettle on a suitable supportA bowl with a curved underside rests on two contoured supports above a stable base. No support bears on the lip.12
Suitable stand or shaped support
  1. Carry the rounded bowl on the support surfaces approved for the kettle; do not suspend it from the lip.
  2. Provide a stable foundation for the complete operating load.

Concept sketches · not to scale. A gas fire-pit setting must also preserve the ventilated equipment cavity, drainage and above-grade ignition controls. Do not use earth to block or bury these components.

A sugar kettle is a complete rounded bowl, not a flat-bottomed vessel. It will not stand level on a flat surface by itself. Plan a suitable stand or shaped support that carries the rounded underside securely. For an appropriate landscape installation, a contractor may prepare a contoured recess in the ground to support and level the bowl; confirm stable bearing, drainage and the final rim elevation before setting it. A shallow scoop in loose earth is not a finished structural design.

For a gas fire pit, the setting must also preserve the required cavity, drainage, ventilation and equipment clearances. Do not bury the kettle or build up earth around it in a way that blocks vents, traps gas or water, or puts the ignition below grade. Have the gas installer approve the complete support and control layout.

Plan the entire route from the freight truck to the final setting, including gate openings, overhead branches and wires, tight turns, slopes, soft ground and the space needed for lifting equipment. Measure the clear opening, rather than relying on the nominal gate size. Send Grove photos of restricted access before delivery.

Orders arrive on a pallet by LTL freight. Arrange a forklift for unloading or select liftgate delivery. A liftgate lowers the pallet to ground level; the carrier does not move it into position or install the kettle. Residential delivery includes a scheduled four-hour window arranged by the carrier after the shipment reaches the destination terminal. Inspect for damage before accepting delivery.

Plan heavy-equipment handling or a professionally assessed team lift before the delivery date. These are heavy, awkward bowls; do not assume that adding a few people makes a manual lift safe. Book a qualified equipment operator or rigging contractor where required by the weight and access conditions. Give them the kettle specification sheet, total lift weight, proposed access route and required reach. A machine’s advertised capacity alone does not establish that it can safely lift the load at the required reach.

  • Move the kettle empty, before plumbing or fire components are connected. Keep people clear of suspended loads and pinch points.
  • Have Grove confirm the lifting and attachment method for your kettle before rigging it. The rim, lip, holes and decorative features are not identified here as rated lifting points.
  • Ask the rigger to protect the kettle surface and prevent concentrated contact loads. Do not drag the kettle across finished paving.
  • Use the bare weights below for initial planning only. Water, stands, media, components and packaging add weight; these figures are not complete assembly or freight weights.

Have the installer verify a stable, level, noncombustible setting, the required separation from combustible surroundings, and safe circulation around hot surfaces. Evaluate overhead structures and vegetation before approving the location. Current manufacturer guidance gives a minimum 84-inch vertical clearance from the burner to combustible materials and 36 inches horizontally; have the installer check the applicable diagram and local requirements for the actual system. A covered patio needs a site-specific clearance and ventilation review; a photograph of another installation is not proof of suitability. See the manufacturer’s current clearance diagrams and burner manual.

The burner plate needs its own adequate support. The 5FT package uses a 50-inch circular aluminum plate. Do not let burner weight bear on an ignition valve box or use gas piping as a support. Have the installer resolve plate support, drainage, combustion-air openings and service access together before the kettle is set. Do not fill the equipment cavity with decorative gravel or concrete. Current guidance calls for at least two opposing ventilation openings with 18 square inches of free area each (36 total); some enclosures require more. Keep them clear of paving, mulch and vegetation, and coordinate their location with the applicable manual.

Check the rim in two directionsTop view of a circular kettle rim with a straight board and spirit level, checked in two perpendicular directions. Recheck after loading.123

Level the rim, then recheck under load.

  1. Use a straight, rigid board that spans the rim and a spirit level. Confirm the board and level are suitable for the span.
  2. Rotate the check 90 degrees to check the second direction.
  3. If correction is needed, safely unload or lift the empty kettle using the agreed method and adjust the underlying support. Recheck stability and level after setting and, for water features, after filling.

Do not place loose shims beneath the lip or adjust supports beneath a suspended load. The drawing illustrates a check, not a lifting method.

Bring the right utilities to the right location

Ask your gas professional to size the supply for the burner input, fuel, run length, fittings, available pressure and other appliances sharing the service. A fitting that connects physically does not prove adequate gas capacity. Confirm any meter or regulator work before hardscape is finished. Use the manufacturer gas-sizing reference with the installer’s calculations.

  • Specify natural gas or propane when ordering. Fuel conversion requires the correct manufacturer-approved components and a qualified installer.
  • Show the gas entry, external shutoff, service access and any required electrical route on the site plan before final setting.
  • For the supplied Platinum system, provide the specified 24VAC transformer and compatible controls. Do not connect mains power directly to the low-voltage ignition; have the electrician follow the model-specific wiring instructions. Have an electrician plan the required outdoor power, protection and disconnect.
  • Leave the equipment area above standing water with a workable drainage path. Keep future landscaping from blocking vents, valve access or electrical service.

Decide where the controls belong before drilling

Platinum controls and manual key valve: planning layoutSchematic section of a rounded gas fire-pit bowl on a support, with burner plate, ignition above grade, open equipment space and a separate adjacent control panel. Numbers correspond to the legend below. No mounting dimensions, cutouts or gas connections are specified.12345

Plan an accessible control location beside the feature.

One possible arrangement uses a separate noncombustible mounting surface. Confirm this layout with Grove and your qualified installer; the sketch does not specify a Grove kettle cutout.

  1. User control / external power switch: accessible from outside the feature, away from the flame and hot bowl. An optional timer or emergency stop needs its own compatible, approved arrangement.
  2. Manual key valve: shown on the adjacent panel. Leave room for the key and service access. A vessel-mounted alternative must be below the burner plate and approved before drilling.
  3. Platinum 24V valve/control box: keep above grade, protected from standing water, with the manufacturer’s required clearance below the plate. Confirm fit for the actual kettle and support height.
  4. Equipment cavity: maintain ventilation, drainage and access. Dashed openings indicate the ventilation requirement, not permission to drill holes at those spots. Do not fill this space with soil or gravel.
  5. Burner plate and support: support the assembly independently of the gas valve, tubing and control box.

Placement concept only · not to scale · gas lines and electrical wiring omitted. Use the manufacturer’s current installation diagrams for clearances and connections. Shut down power and close the manual key valve after use.

Make a marked-up site photo with Grove and the installer showing the user control, manual key valve, power disconnect and the route to each. The user should be able to operate the controls from outside the feature without leaning across flame or reaching through hot media. Leave room for the key to turn and for a technician to reach the valve and connections.

Warming Trends permits a key valve through the vessel sidewall below the burner plate, or on a remote or adjacent mounting surface. That general instruction does not establish a safe cutout location in a Grove cast-iron kettle. Confirm the mounting location and method with Grove before drilling. A nearby noncombustible mounting surface may be part of the installer’s coordinated layout; it must preserve required clearances and service access.

For the supplied Platinum 24V ignition, coordinate the user switch or remote interface, transformer and valve-box location using its own manual. Plan an accessible external power switch. Locate the operating control on an appropriate exterior or adjacent mounting surface, clear of flame and hot surfaces; do not treat a basic spark-button bracket as the Platinum mounting arrangement. Keep the valve box above grade with drainage and sufficient clearance beneath the burner plate. Confirm physical fit before setting the kettle or making any holes. Keep control wiring and components away from heat and water as directed by the manufacturer.

Before fabrication, have the installer document: control model; mounting surface and cutout; clearances above and below the plate; valve and electrical access; ventilation; drainage; and how components can be removed for service. The Platinum/Cobalt manual provides the system-specific layout and electrical instructions.

Make shutdown part of the handover

Close the manual key valve whenever the fire pit is not in use, including with automatic ignition. Automatic gas control does not replace this shutdown step. Warming Trends states this in its ignition FAQs.

For the supplied Platinum system, its manual directs users to switch power off using the remote or wall switch, turn the key valve clockwise to OFF, close the propane bottle or tank if used, and check that the flame is out. Have the installer demonstrate the sequence for the actual system supplied. Do not use this sequence as a lighting procedure for a different ignition.

  • Have the qualified installer test the installation and demonstrate lighting, normal shutdown and emergency shutoff before use.
  • Keep the operating key accessible to the responsible adult and identify which valve isolates the feature.
  • Confirm the approved media arrangement and that the pilot, burner openings, drains and vents remain unobstructed. Do not add wood or other solid fuels to a gas burner.
  • Keep model numbers, manuals and the installer’s contact information with the order. Arrange maintenance at the intervals required by the manufacturer.

If gas is smelled: stop use, shut off the gas if safe, extinguish open flames and leave the area if the odor continues. Contact the gas supplier or fire department from away from the feature. Do not attempt repeated ignition.
