Multiple boilers may be installed together to handle larger sized heating loads, and can be stage-fired. Preassembled water manifolds are available for commercial, multiple-boiler installations.
The boiler is designed for ease of installation and serviceability, with built-in condensate trap and auto air-elimination vent. Each boiler comes with an installation kit that includes boiler and optional DHW gas piping, and all necessary connections, isolation valves, and unions.
