Outdoor Use Only
Do not install or operate the fireplace inside an enclosed room, garage, shed, breezeway, camper, tent, home, or similar enclosed space.

Confirm fuel type, gas-supply routing, shutoff-valve location, and applicable installation requirements before permanent placement.
Professional Gas Installation

The fireplace installation must provide adequate outdoor ventilation and appropriate separation from combustible materials.
Final placement should also account for nearby traffic areas, windows opening into the home, combustible landscaping, overhead materials, wind exposure, moisture, and service access.
Clearance guidance: Review the current Cal Flame Fireplace Owner's Manual and applicable local codes before finalizing installation clearances. Do not rely on the fireplace's physical footprint alone.
Electronic Ignition & Operation
The Key West 905-3 uses an electronic ignition system.
The supplied owner's-manual information identifies an AA battery within the ignition system. If the igniter does not spark, the manufacturer's troubleshooting procedure includes checking, repositioning, or replacing the battery.

Flame Authority Expert Recommendation
Choose the Cal Flame Key West FRP-905-3 when you want a large outdoor gas fireplace that becomes a central architectural feature rather than simply adding a small flame source to the patio.
Its 72-inch width, 79-inch height, wrap-around bottom mantel, 90,000 BTU double burner, Weathered Oak log presentation, herringbone ceramic-brick firebox, and vented configuration make it particularly suited to larger patios, courtyards, poolside living spaces, and permanent outdoor entertainment areas.
Before ordering, confirm the complete 72"W × 41"D × 79"H footprint, approximately 600-lb. weight, foundation capacity, delivery access, Natural Gas supply, ventilation, service access, and finish selection.
If Propane operation is required, account for the separately ordered LP conversion equipment and qualified conversion rather than assuming the standard fireplace is ready for direct LP connection.
