SPECIAL INSTRUCTIONS TO OWNER This manual supplies information for the installation, operation and servicing of the appliance. It is strongly recommended that this manual be reviewed completely before proceeding with an installation. WARNING To minimize the possibility of serious personal injury, fire or damage to your appliance, never violate the following safety rules.
UNIT LOCATION GENERAL INFORMATION Install this appliance in a clean, dry location. INTRODUCTION Site preparation for the Valiant FT should be carried out by paying attention to the dimensions of the particular model The Valiant FT is a condensing, forced draft appliance size and its overall clearances.
clearance. However, access panels from the sides of the unit are also provided for scenarios where the installation allows them to be accessible. This provides larger points of access for greater ease of serviceability. The appliance should be located close to a floor drain in an area where leakage from the appliance or connections will not result in damage to the adjacent area or to lower floors the structure.

The Valiant FT boiler has the capability to be accessed by a building management system (BMS) through Modbus RS485. In case of a cascade system consisting of multiple Valiant FT boilers, the BMS should be accessing the master boiler. Electrical Connection The twisted pair wire coming from the BMS can be connected to the terminal block located under the control panel.
