1. Connect the boiler to a dedicated (max.)15 Amp
breaker.
2. Wire incoming 120 VAC to the black and white wires
labeled “AC In” in the eld wiring box.
3. Ensure that the boiler is properly bonded (grounded).
4. Wire the primary/boiler pump to the yellow and
white wires labeled “Boiler Pump”.
Refer to the “Wiring
Diagrams” section in
the Installation and
Operating Instructions
manual (Appendix) for
more information.
• For multiple-boiler setup, use a secondary loop sensor.
• For zone valves or external peripherals such as wi-
thermostats, use external transformers.
Note: If a load is dened as Reset Heating, the outdoor
sensor must be used for proper operation.
Electrical continued (Section 3.13)Water Piping (Section 3.11)
• Place air separators at the highest point.
• Install the pressure relief valve on the outlet piping of
the boiler in a vertical position. Do not use an isolation
valve between the boiler and relief valve.
• Support all piping with appropriate piping brackets.
• Plumb an appropriately sized expansion tank and make
up the water station into a tting on the suction side of
the circulator.
• Size boiler piping and pump for the BTU output of the
boiler.
For non-oxygen barrier piping systems, use a dirt separator
and/or a side stream lter. Ensure that the system is free of
iron components, and treat with an inhibitor.
We recommend that you always use a primary/secondary
piping conguration (see below for a basic conguration).
In the case of hard water, use distilled or puried water (but
not reverse-osmosis). Glycol systems must use propylene
glycol. For large volume systems, the optimum hardness is
≤2 grains.
Water Chemistry Allowable Limits
Acidity pH 6.6 - 8.5
Chloride < 125 mg/l
Iron < 0.3 mg/l
Copper <0.1 mg/l
Conductivity < 400μS/cm (at 77°F / 25°C)
Water Hardness < 7 grains
Load Setup
1. On theV-10 Touchscreen controller bottom navigation
bar, tap the Setup icon
2. Select a load and then select the load type.
3. Accept the defaults, or change any of the settings.
You can nd more substantial settings in More >
Advanced Setup
4. Tap the Save button.
Manual Pump Purge
After the system is pressurized and you have dened loads,
perform a manual pump purge to ensure air is purged.
On the touchscreen controller, go to More> System
Settings > Site Settings>Set Manual Pump Purge to
"On">OK > Save.
The manual pump purge runs until it is turned off, or when
there is a call for heat.
Electrical (Section 3.13)
5. Wire the respective load pumps into the TB1 Terminal;
for example, PV1, 2, 3, 4.
6. Wire thermostats or end switch dry contacts to Therm
24 Vac, and then connect the other wire to Therm 1, 2,
3, 4 corresponding to the load pump PV1, 2, 3, 4.
7. For a DHW load, wire either an Aquastat to the
appropriate Therm. connection or a 10K Ω type II/B
curve thermister to the DHW sensor connection.
The boiler requires proper grounding, which conforms to all
electrical codes, ensuring proper ame rectication.
