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)
(HD = Heavy Duty Model)
(ASME = ASME Certified Model)
(HD ASME = Heavy Duty ASME Model)
