This Williams freestanding surface-mount accessory is designed to make installation easier when a recessed wall installation is not an option. It allows single-sided Monterey furnaces to be surface-mounted, making it a practical solution for remodels, masonry wall construction, or situations where wall studs do not meet installation requirements. Constructed from heavy-gauge metal, the kit provides a stable, durable structure that supports the furnace while maintaining proper alignment. The soft white finish matches the appearance of a natural gas wall heater, helping the unit look complete and intentional once installed. Side rails and a vent cover are included to streamline installation and reduce the need for additional parts. Designed specifically for Monterey top-vent models, this accessory supports continued use of a reliable natural gas room heater while offering greater flexibility during installation and renovation projects.
