Create Your Perfect Outdoor Masonry Fireplace with Our Selection of Outdoor Fireplace Kits

Updated September 21, 2026

An outdoor masonry fireplace kit can simplify the firebox and chimney geometry, but the finished project still depends on site planning, foundation design, clearances, drainage, local permits and correct assembly. Choose the kit only after confirming how it fits the property.

Start with the location

Place the fireplace where smoke will not routinely blow toward doors, windows, seating or neighboring property. Check overhead branches, rooflines, fences, utilities, setbacks and prevailing wind. The chimney height and termination must follow the kit instructions and local requirements.

Choose the right outdoor fireplace kit

The current Fireplace Kits collection includes ten active products, including 24-, 36- and 48-inch Standard Series kits, New Age zero-clearance models, firebrick and fireplace/oven combinations. Compare:

• Opening size: larger is not automatically better; it affects footprint, fuel use and viewing area.
• Installation type: confirm whether the model is intended for outdoor, indoor or zero-clearance construction.
• Included materials: verify whether ready-mix, firebrick, damper, outside-air components and finish materials are included.
• Finished dimensions and weight: these determine access, foundation and handling requirements.
• Fuel and listing: use only the fuels and configurations allowed by the manufacturer.

Foundation and drainage matter

Masonry is heavy. The base must support the completed fireplace without settlement or frost movement. Requirements vary by soil, climate and local code, so confirm footing depth, reinforcement and slab specifications with the manufacturer and local building authority. Grade the surrounding area so water drains away from the structure.

Plan the finish before construction

Stone, brick, stucco and veneer change the finished dimensions and weight. Select noncombustible materials rated for the intended exposure and temperature. Keep required expansion gaps, ventilation and access points open instead of covering them for appearance.

Installation checklist

1. Obtain permits and review neighborhood or HOA restrictions.
2. Confirm the kit model, dimensions and included components.
3. Mark setbacks and underground utilities.
4. Build the specified foundation and allow materials to cure.
5. Assemble components in the documented sequence.
6. Install chimney and termination exactly as required.
7. Apply approved exterior finishes without blocking functional openings.
8. Complete the manufacturer’s curing and first-fire procedure.

Bottom line

The best kit is the one that fits the site, code requirements, desired finish and installation capability. Treat the manufacturer’s drawings as construction documents, not suggestions, and use qualified masonry and chimney professionals where required.
