LOCATION / MOUNTING CONSIDERATIONS
This water heater is not intended for outdoor installations
Maintain minimal piping distance between the boiler and
the water heater to:
-
Reduce piping heat loss
-
Provide minimal friction loss
Locate water heater in a manner that any leakage from
the heater or water connections will not cause damage
to the area adjoining the water heater or to lower floors
in the structure. When such a location is unavoidable, a
suitable drain pan with adequate drainage should be
placed under the water heater.
The Mini SMART water heater is designed for verti-
cal installation only.
RECOMMENDED CLEARANCES
Install the water heater allowing adequate clearances for
servicing.
Recommended top and bottom vertical clearances is 12
inches minimum for servicing
Zero clearance is permissible to either side of the Mini
SMART, but information labels may be hidden.
Reference the boiler installation manual for minimum
allowable clearances of the boiler.
