Installer or Qualified Service Agency Read Before Proceeding
1. Phantom II boiler is a Direct Vent space heating
boiler.
2. A hot water boiler installed above radiation level
or as required by the authority having jurisdiction
must be provided with a low water cutoff (LWCO)
device. This boiler is equipped with a UL353
listed flow switch which provides low water
protection on this boiler. Where authority having
jurisdiction requires a separate LWCO, the
following kits are available:
• Auto reset LWCO: 105591-01
• Manual reset LWCO: 108182-01
Factory installed flow switch in this boiler meets
requirements of 248 CMR 5.00 Massachusetts
Amendments to NFPA 54 Section 5.10(6) 10.3.5
Safety Control.
3. Inspect shipment carefully for signs of damage.
See Figure 6-1 for location of parts shipped
loose with boiler. Any claim for damage or
shortage in shipment must be filed immediately
against carrier by consignee. No claims for
variances or shortages will be allowed by boiler
manufacturer, unless presented within 60 days
after receipt of equipment.
NOTICE:
When replacing control, use boiler
control service part listed in Section 20 Service
Parts. Boiler control service part is compatible
for all models. Factory installed control is only
compatible with purchased boiler.
WARNING
Asphyxiation Hazard, Burn Hazard, Electrical
Shock Hazard.
• Carefully read all instructions in literature
packet and posted on boiler before attempting
installation, startup, or service of this boiler.
Perform steps in order given. Failure to follow
all instructions in proper order could result in
severe personal injury, death or substantial
property damage.
• Use proper personal protective equipment
when installing, servicing, or working near this
boiler. Materials of construction, flue products,
and fuel contain alumina, silica, heavy metals,
carbon monoxide, nitrogen oxides, and/or
other toxic or harmful substances that can be
hazardous to health and life and that are known
to the State of California to cause cancer, birth
defects, and other reproductive harm.
• Do not disconnect pipe fittings on boiler or
in heating system without first verifying system
is cool and free of pressure and that your
clothing will protect you from a release of hot
water or steam. Do not rely solely on boiler
temperature and pressure gage when making
this judgement.
• Install all guards, cover plates, and
enclosures before leaving boiler in operation.
• Disconnect electrical supply before installing
or performing maintenance.
• Always use a combustion analyzer to verify
proper operation. See Section 14 Start-up and
Checkout for procedure and guidelines for
checking carbon monoxide (CO) levels. Failure
to use a combustion analyzer could cause
operation of boiler with elevated (CO) levels,
resulting in severe personal injury, death or
substantial property damage.
• Default altitude setting is 0-2,000 ft. (610
m). See Section 14: Start-up and Checkout for
elevations above 2,000 ft. (610 m).
• For 150 and 180 LP installations above 2,000
ft. (610 m), conversion kit 111745-01 is required.
!
NOTICE:
Size boiler properly relative to design
heat load or, if using DHW priority, the peak
hot water load, whichever is larger. A grossly
oversized boiler will cycle excessively leading to
premature failure of boiler and its components.
Warranty does not cover damage from excessive
cycling.
• For heating systems employing
convection radiation (baseboard
or radiators), use an industry
accepted sizing method such as
the I=B=R Guide RHH published
by the Air Conditioning, Heating and
Refrigeration Institute (AHRI).
• For new radiant heating systems,
refer to radiant tubing manufacturer's
boiler sizing guidelines.
• For system including indirect water
heater, ensure boiler has output
called for per indirect water
heater manufacturer's instructions.
