piping.
• See suggested piping in this manual and boiler manual.
Mechanical
Each boiler must be connected with primary/secondary
piping and supplied with a boiler circulator.
For details, see FIELD WIRING information beginning
on page 22.
BOILER POWER SUPPLY
• Connect minimum 120 VAC power to boiler as directed
on the boiler wiring diagram (on boiler and on page 32).
INPUTS & OUTPUTS
• Each boiler provides three input/output pairs. Input
circuits are 24 VAC. DO NOT apply voltage. Use dry
contacts only. Outputs are 120 VAC, 2.2-amps max (use
relays if loads exceed 2.2 amps or if outputs must be 24
VAC or must be isolated contacts).
Step 2
• The input/outputs can be used with zone thermostats and
Electrical
zone circulators or zone valves (requires isolation relays
unless valves are 120 VAC), providing up to three zones
per boiler on a multiple system.
• Each boiler also provides an unpowered output for its
boiler circulator. Use a external relay if circulator requires
more than 10.0 amps at 120 VAC.
• If a system pump is to be operated by the SlimFit
controls, connect the pump to any of the available
outputs. The system pump can be activated by a
remote contact or can be automatically activated on
heat demand. Set up for pump operation is done in the
ACTIVATE OUTPUT screen of the WIZARD.

• As shown in the suggested piping examples, DHW tanks
can be either piped directly off of individual boilers or as a
separate zone in the heating system.
• See page 6 for additional information on multiple boiler
installation options.
SENSORS
• Connect an outdoor sensor, system supply sensor and
system return sensor to at least one of the boilers in a
multiple boiler system..
• Preferably, connect outdoor, system supply and system
return sensors to more than one boiler to provide
redundancy. If one of the sensors fails, the master boiler
SlimFit control automatically looks for an available sensor.
MULTIPLE BOILER COMM CABLES
• For multiple boilers, connect boiler-to-boiler communication
cables as directed on page 31.
