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)HTR : Heater
2)(200, 250, 300 or 400) : Input rating (Btu/hr) X 1000
3)NT : MiniMax NT Series
4)LN : Series Character
5)NH : Gas type (Natural gas) and ignition system (Hot Surface Ignition)
6)Options :
Blank: Standard Model
ASME: ASME Certified (Bronze Headers)
ASHI: ASME Certified Bronze Header and High Altitude Rating
HALT: High Altitude Rating
