IBC EX 850 Quick Reference Installation Guide

We recommend that you always use a primary/secondary piping
conguraon (see below for a basic conguraon).
In the case of hard water, use dislled or puried water. Glycol
systems require the use of propylene glycol. For large volume
systems, the opmum hardness is ≤2 grains.
Water Chemistry Allowable Limits
Acidity pH 6.6 - 8.5
Chloride < 125 mg/l
Iron < 0.5 mg/l
Copper <0.1 mg/l
Conducvity < 400μS/cm (at 25°C)
Water Hardness < 7 Grains
• Place an air separator at the highest point. These must be
installed above each boiler.
• Install the pressure relief valve in a vercal posion. Do not
use an isolaon 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 staon into a ng on the sucon side of the
circulator.
• Size boiler piping and pumps 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.
Electrical (Section 3.10)
1. Connect the boiler to a dedicated (max.)15 Amp breaker.
2. Wire the AC to the black and white wires labeled in the
Field wiring box.
3. Ensure that the boiler is properly bonded (grounded).
4. Refer to the “Wiring Diagrams” secon in the Installaon
and Operang Instrucons manual (Fig 42) for more
informaon.
5. Wires labelled “Boiler Pump:” Wire power for the boiler
pump to the black wire, and the boiler pump “L” (hot)
connecon to the yellow wire.
6. Wire the respecve load pumps into the TB1 Terminal; for
example, PV 1, 2, 3, 4.
Electrical continued (Section 3.10)Water Piping (Section 3.8)
1. 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.
2. For a DHW load, wire either an Aquastat to the appropriate
Therm. connecon or a 10K Ω type II/B curve thermister to
the DHW Sensor connecon.
The boiler requires proper grounding, which conforms to all
electrical codes, ensuring proper ame reccaon.
• For mulple-boiler setups, use a secondary loop sensor wired to
the Master boiler.
• For zone valves or external peripherals, use external
transformers.
Note: If a load is dened as Reset Heang, the outdoor sensor
must be used for proper operaon.
Express Setup
1. On theV-10 Touchscreen controller, tap the Home (Standby)
screen>Main Menu>Express Setup.
2. Do the following:
a. Tap the Enter Design Outdoor Temperature box, and
enter a value.
b. Tap Set Clock to set the me and date.
c. Tap Save.
3. Select a load and then select the load type.
4. Accept the defaults, or change any of the sengs.
5. You can nd more substanal sengs in "Installer Sengs".
6. Tap the Save buon.
Manual Pump Purge
Aer 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 Main Menu> Installer
Sengs> System Sengs > Site Sengs>Set Manual Pump
Purge to "ON">OK>Save.
The manual pump purge runs unl it is turned o, or when there
is a call for heat.
