Additional instructions for PROPANE gas installations
Ultra boilers are shipped ready to fire natural gas ONLY. (Exception: Ultra-80LP boilers are propane-ready.) You must install the high altitude propane orifice supplied in the High Altitude Kit if the boiler will be connected to propane. Follow all instructions in this document, the Propane Conversion Instructions and the Boiler Manual. Note that Ultra-
80NG, Ultra -310NG only and Ultra -310 Series 1 boilers also require a burner change for propane firing, as shown in the gas conversion instructions.
DO NOT install the sea level orifice supplied in the propane conversion kit — use the orifice specified below. Failure to comply could result in severe personal injury, death or substantial property damage.
The high altitude propane gas orifice is located in the High Altitude Kit orifice bag. Install ONLY the orifice marked with the correct boiler size as shown below.
