Installation & Service Manual
TM
A closet is any room the water heater is installed in which is
less than 455 cubic feet for SNR150-100 and SNR200-100
models and 671 cubic feet for the SNA285-125 through
SNA500-125 models.
An alcove is any room which meets the criteria for a closet
with the exception that it does not have a door.
Example: Room dimensions = 6 feet long, 6 feet wide, and
9 foot ceiling = 6 x 6 x 9 = 324 cubic feet. This would be
considered a closet for a Shield Water Heater.
