Features
- Factory Primo part for the Round: made for the Primo Round kamado rather than a universal fire box.
- Keeps the airflow path: Primo says the fire box is designed to maintain the grill's airflow; its opening lines up with the draft door in the base.
- Holds the whole charcoal load: Primo's Quick Start Guide calls for a full fire box of charcoal for smoking and searing temperatures and half a fire box for two-zone cooking.
- Carries the grates: the cast iron charcoal grate sits in its bottom and the cooking grate rests on top of it (Primo Round assembly instructions).
- Ash drops through: stirring the used charcoal with the ash tool drops the ash through the fire grate (Primo Quick Start Guide).
- Lifetime ceramic coverage on the grill: Primo gives the original purchaser a limited lifetime warranty on all ceramic parts of the grill.

Installation planning
- Confirm the model first: this fire box is for the Primo Round. Oval grills use their own fire boxes, and Primo's warranty does not cover unauthorized parts.
- Warranty route: if the original fire box has a ceramic defect, contact your dealer with the model number, serial number and proof of purchase before buying a replacement; Primo replaces defective parts, the purchaser pays shipping, and the old part must be disposed of once the replacement arrives.
- Fitting: Primo's Round assembly instructions insert the fire box into the grill with its opening aligned with the draft door opening, then put the charcoal grate in the bottom of the fire box and the cooking grate on top. Primo publishes no separate fire box replacement instructions, so ask us before you start.
- Handling the grill: Primo's Round instructions say never to lift the grill by the hinge, and the owner's manual says never to lift it by the hinge mechanism attached to the bands.
- Grill placement: Primo's Round spec sheet asks for 10 in. of clearance behind the grill so it opens properly and at least 2 in. around the outside of the grill. On wooden tables or any surface other than a metal stand, set the grill on its ceramic feet (owner's manual).
- Fuel and lighting: use only natural lump charcoal, lit with a fire starter cube or two, a chimney or an electric starter with the dome open. Never use lighter fluid; Primo says it is absorbed by the ceramics, gives food a fuel taste and voids the warranty.
- Reusing charcoal: Primo says charcoal can be relit 2-3 times; stir the used charcoal with the ash tool so the ash drops through the grate, and add about 30% new charcoal before building a new mound.
Care: Clean the ash from the cast iron grate to prevent buildup, clean the cooking grates after each use, and check and tighten the band bolts several times a season and after high-heat cooks (Primo warranty maintenance).
Warranty
Primo Ceramic Grills gives the original purchaser of the grill a limited lifetime warranty on all ceramic parts, a limited 5-year rust-through warranty on metal parts other than cast iron, a limited 1-year rust-through warranty on cast iron parts and on all other parts and accessories unless stated otherwise, and a limited 30-day warranty on felt gaskets and thermometers. Primo's warranty page does not state a separate term for a fire box bought as a replacement part; ask us to confirm the coverage before you order.
Primo's conditions: coverage is for the original purchaser; the product must be installed according to Primo's instructions; keep a bill of sale or payment record. Replacement parts ship at the purchaser's expense. Not covered: damage from use, misuse, improper installation or storage, unauthorized service or parts, lack of maintenance (including not removing ash from cast iron grates and not checking and tightening bolts several times a season), removal and reinstallation, service calls, labor, travel, diagnostic and freight charges. Claims go through your dealer with the model number and proof of purchase, or through Primo's online warranty claim form; international claims are not accepted. Full terms are on Primo's warranty and parts page.
