31. Heater Rating Plate
The heater rating plate is a quick reference for information about a heater and its instal-
lation requirements. In addition, the Serial No. on the rating plate identifies compo-
nents used in manufacturing that specific heater. The serial number is coded to identify
the gas valve and ignition type that was installed on the heater at the time of manufac-
ture. This information is required if service and/or replacement parts are required.
Follow the example below to decode the heater Serial No.

IMPORTANT: The serial number code can only identify the original equipment. Be-
fore installing or servicing, check for a gas conversion label.
When inquiring about replacement parts, always provide the complete Model No. and
Serial No. Each heater has a "Replacement Parts Label" attached that identifies parts
specific to that heater, as well as the Model and Serial No. of the heater.
