Page 4: General Information
The appliance should be located in an area where leakage within the unit or at its connections will not result in damage to the area adjacent to the appliance or to lower floors of the structure. PENSOTTI will not be responsible for any damage resulting from leaking if adequate drainage is not provided. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. - Page 5 Check the Rating Plate PENSOTTI units come from the factory configured for use with natural gas. Prior to installation, check the rating plate of the boiler to ensure the unit matches gas type, gas pressure, water pressure and electrical supply. If the unit does not match the requirements, do not install.
- Page 6 GENERAL INFORMATION The “operating instructions” chapter of this manual must be read carefully as it provides information on the operation and the operating limits of the appliance. After the removal of all the packaging, check that the appliance has not been damaged. In case of doubt, do not attempt to use the product but refer to the supplier.
- Page 7 Many jurisdictions require the installation of carbon monoxide detectors in building where a side wall vented fuel burning appliance is installed. Installers must abide by local code requirements regarding the installation of CO detectors. The use of a certified carbon monoxide detector is recommended but not required by PENSOTTI. “In the State of Massachusetts only”...
