Fireside maintenance is critical to keeping your Cleaver-Brooks boiler operating safely and efficiently. Each CB Commercial Fireside Kit is designed to include all the essential materials needed for a complete annual fireside cleaning and rebuild. Kits typically include high-temperature gasketing, refractory materials, door insulation, rope or tadpole seals, and hardware components — everything required to properly reseal and restore the combustion chamber and fireside surfaces.

Regular fireside maintenance helps prevent heat loss, corrosion, and combustion inefficiencies caused by soot buildup or air leaks. These kits are manufactured to match the original Cleaver-Brooks specifications, ensuring proper fit and long-term performance across a variety of models, including CB, CBH, CBLE, and others.

Using a complete kit saves time during shutdowns by providing all the right parts in one convenient package. For best results, pair your fireside maintenance with a waterside kit and inspect gaskets, doors, and observation ports at each cleaning interval. BoilerSupplies.com stocks a full selection of replacement kits for both fireside and waterside maintenance — ready to ship to keep your system running at peak efficiency.
