The OB52 is Dacor’s 52-inch built-in gas grill from the discontinued Epicure/Heritage outdoor line: three U-shaped main burners at 20,000 BTU each, two side burners, and a 13,000 BTU infrared rotisserie burner, for 109,000 BTU total across the unit. It was sold in separate liquid propane (OB52/LP) and natural gas (OB52/NG) versions, with the fuel type fixed at the factory rather than user-convertible.
With six burners running off the same manifold, an even flame on one burner and a weak one right next to it usually points at a clogged port or an orifice rather than a regulator problem across the whole grill; a problem affecting every burner at once is more likely the regulator or the gas supply itself. The side burners, rotisserie motor and main burners are separate circuits, so a rotisserie that will not turn does not usually mean the cooking side has a problem too.
