INSTALLATION AND MOUNTING
If the Y–Series Electronic Boiler Control was not mounted on the boiler by the factory, care should be taken to select a
suitable mounting location. The control should be mounted on a solid and permanent base. The control enclosure is
NEMA 3R rated, rainproof and sleet resistant, and can be mounted outdoors if required. The unit should be readily
accessible for maintenance and installation purposes, and should be mounted so that the indicating lights are at a height
and location convenient for viewing.
MECHANICAL INSTALLATION
Install the control within 10 feet of the boiler(s). The control must be mounted vertically with the conduit holes facing
downward. The conduit holes are sized to accommodate standard conduit fittings. If additional or larger conduit fittings
are required, the holes should be located on the bottom of the module.
Mount the control using the mounting bracket and appropriate 3/8” or 1/4” hardware in four (4) places.
A minimum of eighteen (18) inches clearance from the front, and six (6) inches clearance on all other sides is required for
service access. The hinged right side of the box should be installed with sufficient clearance (minimum 3” from the bolt
holes on the right side) to open the cover.
An electrical distribution sub-panel containing appropriate disconnect switches and surge suppressors is required at or near
the equipment location(s).
To access the control board, remove the interior front panel by unscrewing the four (4) decal panel fasteners.
INSTALL CONDUIT AS APPROPRIATE.
NOTE #1 : Shielded 18 gauge cable must be used to connect the sensors to the Boiler Control Module. The shielded
cable should be protected by conduit whenever possible.
NOTE #2 : 18 AWG - Stranded wire must be used for all connections to printed circuit board (PCB). Solid conductors
should not be used because solid wire conductors can cause excessive tension on contact pointS.
ELECTRICAL INSTALLATION
ELECTRICAL CHARACTERISTICS: 120 VAC, 60 Hz, 0.5A
120 VAC FEEDER CIRCUITS
Install a surge protection device sized appropriately for your installation at each module.
Install a separate disconnect means for each load. Use appropriately sized wire for equipment as defined by NEC and/or
local code. All primary wiring should be 125% of minimum rating.
It is strongly recommended that the Y-Series Electronic Control Module and the boiler(s) be supplied from the same power
source.
