MOUNTING On vertical vents, the vent damper may be mounted with the actuator in any position. On horizontal vents, do not mount the actuator either directly above or directly below the vent pipe; mount the vent damper actuator to the side of the vent. The vent damper is set up for a continuous pilot system. If the vent damper is installed on a system with an Intermittent Pilot or Hot Surface Ignition the energy savings of the vent damper can be improved by plugging the hole in the vent damper

VENT DAMPER OPERATION For safe, efficient operation, the vent damper and all flue-product-carrying areas of the appliance must be checked annually, with particular attention given to deterioration from corrosion or other sources. Check vent damper operation as follows: 1. When the boiler is off, check that the vent damper position indicator points to the closed position, below.

Systems with multiple zones may require an additional circulator. Consult manufacturer's data for valve pressure drops. When an indirect water heating system is used, it is recommended that a separate circulator be installed to meet the required flow and pressure drop conditions of the indirect water heater. We recommend that the make-up water from the cold water line have a check valve, gate valve, and feedwater regulator set at 12 psig. Install unions and gate or ball valves at inlet and o
