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 either LP or 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.
- Page 6 Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Pressures in excess of 14”WC may damage the internal components of this boiler. Pensotti REQUIRES replacment of the gas valve if it is subjected to pressures in excess of 14”WC. Faliure to comply could cause dangerous operating conditions, fire, explosion, bodily injury or possible death.
