Why Primo ceramic grills
Primo is the kamado category’s only oval-bodied ceramic grill. Founded in 1996 by George Samaras and acquired by Empire Comfort Systems in fall 2019, Primo’s Patented Oval Design (introduced in 2002) is the structural feature that still distinguishes it from every other ceramic kamado on the market — two distinct cooking zones along the long axis of the firebox, so a single Primo sears steaks on the direct side while smoking ribs or roasting vegetables on the indirect side at the same time.
The five Primo grill families
- Junior Oval (PGCJRH / PGCJRC) — 210 sq in main, 360 sq in with the Extension Rack, 100 lbs. The most portable Primo, compatible with the Primo GO travel cradle.
- Round Charcoal (PGCRH / PGCRC) — 280 sq in on the traditional round kamado footprint, 200 lbs. Same Premium-Grade Ceramics and post-2019 upgrades as the ovals.
- Large Oval (PGCLGH / PGCLGC) — 300 sq in main, 495 sq in with the rack, 152 lbs. The smallest oval to accept the optional Fire Box Divider.
- X-Large Oval (PGCXLH / PGCXLC) and X-Large Jack Daniel’s Edition (PGCXLHJ) — 400 sq in main, 680 sq in with the rack, 250 lbs. Primo’s flagship oval; the Jack Daniel’s variant adds branded ceramic glaze and an optional Jack Daniel’s grill table.
- XX-Large Oval (PGCXXLH / PGCXXLC) — 500 sq in main, 800 sq in with the rack, 282 lbs. Entertaining-volume oval, large enough for a suckling pig or 12 racks of ribs.
Every size sells as Head Only (ceramic grill body alone, for built-in islands and existing cradles) or All-In-One (adds the Cradle Stand with locking casters, side tables, ash tool, and grate lifter — ready to grill out of the box).
Warranty & shipping
Primo backs every ceramic body with a Limited Lifetime warranty (20-year guarantee). Serene Yards ships every Primo variant free, nationwide, directly from authorized Empire Comfort Systems distributors.
How do you control temperature on a Primo — low-and-slow vs hot-and-fast?
Primo’s temperature range is 151°F to 850°F+ across every model, controlled with three components: the 6-position aluminum damper top (the cap-style vent on top of the dome), the 5-position lower air control slider (the draft door at the base of the firebox), and the amount of lump charcoal you load.
General approach. Top vent and bottom slider work together as an airflow loop — air enters at the bottom, passes through the burning lump charcoal, and exits through the top damper. More airflow runs hotter; less airflow runs cooler. The 6-position damper and 5-position slider give you stepped, repeatable settings rather than analog fiddling.
Hot-and-fast (searing, pizza, high-heat grilling). Full firebox of lump charcoal, both vents open. Once embers are established, open the damper top fully and the lower slider to the highest position. The Easy Lift Hinge (70% reduction in lid-lift force) makes it easier to peek and close the dome quickly — temperature recovery happens fast on the ceramic body.
Holding a steady temperature (grilling, baking, roasting). Approach the target from below — Primo’s published guidance is that when you’re within 25°F of your target, close the top damper to one-third open and wait 1–2 minutes for the temperature to stabilize. A ¼″ damper move can shift temperature by as much as 25°F, so dial in small increments rather than large adjustments.
Low-and-slow (smoking). Smaller charcoal load, both vents nearly closed. The ceramic body’s insulation makes low-and-slow exceptionally fuel-efficient once stable — a single charcoal load can run for hours-to-overnight at smoking temperatures, with very little adjustment needed once the cooker locks in.
Use 100% natural lump charcoal (not briquettes) — briquette binders produce more ash and a less stable burn profile that can shift temperature behavior off Primo’s published settings.
