INSTALLATION
2-9
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.
5. Pipe the water safety valve from the outlet of the valve to a safe blow-off
point.
NOTE:  Do not alter water temperature/pressure gauge assembly in any way.
6. Drain valve is connected to the lowest opening at bottom rear of boiler.
Carry piping from the outlet of the valve to safe drain point. Provision
should be made for easy access to drain valve of boiler.
NOTE:  The water connection on the top of the boiler is the outlet connection. The
water connection on the rear of the boiler is the inlet connection.
7. Install fi ltration to remove particulates if appropriate.
8. Install bypass chemical feeder for corrosion inhibitor maintenance if
appropriate.
9. Install corrosion coupon holder to assess corrosion inhibitor performance if
appropriate.
NOTE:  The boiler is provided with a drain valve connection and a drain valve.
10. Heating system:
» An automatic pressure activated water make up valve with back
fl ow preventer. It must be set to maintain required Net Positive
Suction Head (NPSH) for re-circulating pumps, a positive system
pressure at the highest point of at least 5-10 PSIG, and make up
water valve should be designed to add water to the system at the
outlet of the boiler and should not be fed directly into the boiler.
» Air removal equipment, including an air separator and automatic
breather valves, along with a functioning expansion tank . Each
must be designed to system specifi cations.
11. When used in conjunction with a refrigeration system, install the boiler
