Section 1: Heater Identification Information
To identify the heater, see rating plate on the inner front panel of the heater. There are two designators for each
heater, one is the Model Number and the other is the Heater Identification Number (HIN).
a. Heater Identification Number (HIN)
The following example simplifies the identification system:
1) MT : MasterTemp
2) Model Size : (175, 200, 250, 300 or 400) : Input rating (Btu/hr) X 1000
3) Fuel Type : (LP = Propane gas or NA = Natural gas)
4) Construction : (STD = Standard Model)
