Cables are
60" long.
This results
in less than
12" between
cascaded
units.
Multiple Cascade Communication cables can be connected for longer distances between boilers. But, each
additional Cascade Cable reduces the maximum number of boilers that can be cascaded by one unit.
NOTES: The cascading communications cable is 60" long. Routing for the FT Floor models can be via the side floor
plastic knock-outs provided. Place boilers within 16" from each other.
Routing for the wall-mounted units can be via the bottom or back side knock-outs. Place unit within 12" from
each other. Follow local codes for both systems.
