VI. Water Piping and Trim
(continued)
The flow switch is factory provided. Follow Section
VI, Paragraph A and Section VIII ‘Electrical’ of
these instructions to install and wire the flow switch.
3. Circulator (Required)
– Usually at least two
circulators will be required to properly install an
Phantom X boiler. See Paragraph B above for
information on sizing the circulators.
4. Expansion Tank (Required)
– If this boiler is
replacing an existing boiler with no other changes
in the system, the old expansion tank can generally
be reused. If the expansion tank must be replaced,
consult the expansion tank manufacturer’s literature
for proper sizing.
5. Fill Valve (Required)
– Either manual
(recommended) or automatic fill valve may be used.
However, if automatic refill is employed, a water
meter must be added to evaluate the makeup water
volume taken after initial fill and eliminate any
water leakage as early as possible.
6. Automatic Air Vent (Required)
–At least one
automatic air vent is required. Manual vents will
usually be required in other parts of the system to
remove air during initial fill.
7. Manual Reset High Limit
- Phantom X boilers
have factory provided UL353 listed boiler control
and UL1434 listed manual reset high limit. An
optional manual reset external high limit is available
from Velocity Boiler Works, LLC to meet local code
requirements.
8. Y-strainer (Recommended)
– A Y-strainer
or equivalent strainer removes heating system
debris from hydronic systems and protects boiler
heat exchanger from fouling. Install the strainer
downstream of full port isolation valve at the inlet
side of the circulator for easy service.
9. Flow Control Valve (Strongly
Recommended)
– The flow control valve prevents
flow through the system unless the circulator is
operating. Flow control valves are used to prevent
gravity circulation or “ghost flows” in circulator
zone systems through zones that are not calling for
heat.
10. Isolation Valves (Strongly Recommended)
–
Isolation valves are useful when the boiler must be
drained, as they will eliminate having to drain and
refill the entire system.
11. Drain Valve (Required)
– Drain valve is
packaged loose with boiler and must be installed
in the location shown in Figure 25 or 26 “Factory
Supplied Piping and Trim Installation”.
12. An optional LWCO with manual reset
is
available from Velocity Boiler Works, LLC to meet
local code requirements.
