Installation, Fuel, and Compatibility
Install only in a compatible outdoor enclosure with the correct liquid propane supply.
The manufacturer catalog identifies enclosure ventilation on at least two sides, a minimum 50% free air space, a minimum 2-inch bottom clearance, and size-dependent combustible clearances for the square flat insert family.
Installation safety: These are family-level guidelines, not a substitute for the current model-specific manual or applicable local codes. Have gas work performed by a qualified professional where required.
Liquid Propane Supply
This exact part number is configured specifically for Liquid Propane and a small-tank LP application.
The propane supply, regulator arrangement, gas pressure, hose or connector setup, and related components must meet the requirements of the exact model and installation.
Do not substitute natural gas for this LP configuration unless the manufacturer specifically provides an approved conversion pathway for this exact model.
Match Lit Ignition
This configuration uses Match Lit ignition, so the operating procedure differs from electronic-ignition versions.
Use only the lighting and shutdown procedure specified by the manufacturer for this exact configuration.
Enclosure Planning
The enclosure must be designed around more than the visible pan dimensions.
Cutout dimensions, ventilation, drainage, structural support, propane access, serviceability, surrounding materials, and required clearances all need to be coordinated with the exact insert.
Ventilation
The manufacturer information for the square flat insert family identifies ventilation requirements on at least two sides of the enclosure and minimum free-air requirements.
Do not obstruct required ventilation openings with decorative finishes, storage, landscaping materials, or other enclosure components.
Drainage and Water Management
HPC Fire describes the certified square flat insert family as using raised burner hubs and weep holes for water mitigation.
The complete enclosure should still be designed so water can drain properly and does not remain trapped around the burner, gas connections, or related components.
Clearances and Surrounding Materials
Required clearances depend on the exact product and installation conditions.
Do not apply clearance measurements from a different pan size, HPC model, fuel configuration, or ignition configuration to this 18-inch LP Match Lit model.
