Dual Fuel Model Number Designation
Option Note
Any and all optional equipment for a water heater must be
called out in the written specifications. A model number
in and of itself does not reflect any optional equipment
selected.
Example: MSH400-ST-120SLT5
A Hubbell vertically installed 400 gallon dual fuel marine water heater with
a factory installed steam heating coil as the primary heating source and
a 120 KW electric heating element to operate as the secondary heating
source. Tank is cement lined. Power required is 440 VAC, 3 phase, 60 Hz.
Please note that steam heating capacity and construction features are not
identified in the model number and therefore must be noted in the written
specifications.
(Manufacturer reserves the right to change specifications without notice.)
