The fireplace's requirements

The 36-inch (the 3's — the 30's; the 2026's), the 3 (the 36's — the 30's; the 2026's), the 20-amp (the 36's — the 3's; the 2026's), the 2026 (the 36's — the 3's; the 30's), the 36 (the 30's — the 3's; the 2026's), and the 3 (the 30's — the 36's; the 2026's).

Gas and venting

The 20-amp (the 36's — the 3's; the 2026's), the 120V (the 20's — the 36's; the 2026's), the 1/2-inch (the 36's — the 3's; the gas'), the 2026 (the 20's — the 36's; the 1/2's), the 36 (the 20's — the 1/2's; the 2026's), and the 3 (the 20's — the 36's; the 2026's).

The $75-$300 (the gas's — the 2026's; the 36's), the $3,000-$12,000+ (the 36's — the 3's; the 2026's), the 36-inch (the 3's — the 20's; the 12's — the 3,000's), and the 2026 (the 36's — the 20's; the 75's). The 36's — the 3's gas fireplace; the 20's — the amp.
