Electrical Supply
Adhere to the following for electrical supply installation:
1. Locate electrical schematic diagram, a copy of which is inside of the panel
box.
2. Ensure the information on the electrical drawing corresponds to your
voltage and frequency. Check the supply voltage and make sure that there
is no over- or under-voltage exceeding 10% of the nominal value.
3. Install a separate fuse switch for the contactor and a separate fuse switch
for the circulating pump. If pump motor is 3/4 HP or larger, install an
across-the-line starting switch ahead of the circulating pump motor.
4. Install wiring and ground in equipment in accordance with authority
having jurisdiction or in absence of such requirements the National
Electrical Code, ANSI/NFPA.
5. Provide a fused disconnect sized for the unit. Size fuses according to motor
name plates and local electrical codes.
6. Connect power to the terminal strip as supplied on the inside of the panel
box.
Water Supply
Install Water Piping
All water supplies contain some solids, dissolved gases or dissolved minerals.
These may cause corrosion, deposition and/or fouling of equipment. To prevent
these contaminants from impacting boiler performance, valve operation and
general pipe longevity, each location must be analyzed and treated accordingly.
Adhere to the following for water piping installation:
1. Isolation valves and unions are recommended on both water connections
for ease of service.
2. Install piping so that the boiler is not supporting any additional piping.
3. Install manual purging valves in all loops and zones. Install a pressure-
reducing (automatic fi ll) valve in the cold water fi ll line to the boiler system.
Check that the proposed operation of zone valves, zone circulator(s) and
diverting valves will not isolate air separator(s) and/ or expansion tank(s)
from the boiler. Clearance from hot water pipes to combustibles must be at
least 6 inches (152 mm).
4. Pipe the water supply line to the lower opening on the back of the boiler.
Water stop valve should be in line between the boiler and the fi rst piece
of equipment. Hot water outlet should be piped to process/equipment
requiring hot water. Water makeup supply should be installed. Hot water
inlet should be piped to the make-up water supply.
