This Burnham Commercial Canopy Assembly is designed for high-altitude applications. Comprising seven sections, it is specifically engineered to be compatible with PVG model boilers. The assembly's primary function is to safely and efficiently direct combustion gases from the boiler to the outside environment. It is constructed from durable materials to withstand the harsh conditions associated with high-altitude operations. The canopy assembly also aids in maintaining optimal boiler performance by ensuring proper ventilation and reducing the risk of backdrafts.
