Model No. Decoding
Example: EEDU400-6
• Model Designation EEDU
• Size 400
• Series No. -6
The Series No. which changes when the product line is re-certified (see
chart on page 3) is important in the selection of certain replacement parts.
Suffixes to the Model No.
2 = Two Stage Valve
H = High Altitude Orifices
MV = Electronic Modulation
S = Stainless Steel Heat Exchanger
De-Coding a Serial No.
Sample:
E AZJ 66 K8 N 12345 MV3
1 | 2 | 3 | 4 | 5 | 6 | 7
1 = Stainless steel heat exchanger (a standard
aluminized heat exchanger has no letter suffix)
2 = Date code (see page 3)
3 = Ignition code (Reference Form P-VALVES)
4 = Valve code (Reference Form P-VALVES)
5 = N is natural gas; L is propane
6 = Consecutive number
7 = Maxitrol system (optional)
