The RH PETERSON MCS-30 is a 30-inch Mountain Crest Split Oak refractory ceramic gas log set designed as a replacement for vented gas burner systems. The set includes 8 hand-crafted ceramic logs, each molded from real wood samples and hand-painted for a realistic appearance. Internal reinforced steel rods are embedded in each log to maintain structural integrity at sustained high temperatures. This log set is intended for use with a compatible vented burner and valve kit, and is not a universal replacement. Installation is performed by a qualified gas appliance technician.
The MCS-30 is designed for residential vented gas fireplace applications. It was specifically engineered for use with the Peterson G31 burner, which is available with multiple valve configurations including match light (natural gas only), manual, millivolt, and electronic ignition. The log set is not rated for vent-free or B-vent direct-vent systems where log certification is required for a different burner class. Installers should confirm burner certification before placing the log set.
The MCS-30 was specifically designed for use with the Peterson G31 vented burner. It is not a universal log set and must only be used with a certified, compatible burner and valve kit. Using this log set with a non-certified burner creates risk of fire, carbon monoxide poisoning, and property damage.
Installation of gas log sets must be performed by a licensed gas appliance technician or qualified HVAC professional in accordance with local codes and NFPA 54 (National Fuel Gas Code). Shut off the gas supply and allow the appliance to cool completely before servicing or placing logs. Confirm the burner model and certification match before installing the log set. Do not operate this log set in a vent-free, insert, or non-vented fireplace application.
