WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
equipment.
Cements for plastic pipe should
be kept away from all sources of
ignition. Proper ventilation should
be maintained to reduce the hazard
and to minimize breathing of cement
vapors.
No shutoff of any kind may be
placed between the safety relief
valve and the equipment, or in the
discharge pipe between such valve
and the atmosphere. Doing so may
cause accidental explosion from
overpressure.
Discharge from safety relief valve
must be confi gured so that there
is no danger of scalding personnel
or causing equipment damage.
Provisions must be made to properly
drain safety relief valve discharge
piping.
For reasons of safety, the hot exhaust
gas duct and chimney must be
insulated or shielded within the
locality of the heater in compliance
with local codes and regulations.
Ð
CAUTION
The stack arrangement and draft
conditions should be in accordance
with the information in this manual for
proper performance of the equipment.
NOTE: Do not bolt the skids to the housekeeping pad/fl oor until all of the piping
has been reassembled and tightened.
4. Ensure the skids are level and fl at before fastening the skids together with
the supplied bolts. The skids should be leveled front to back, side to side
and corner to corner. Failure to properly level the skids will result in piping
misalignment. A level or laser level should be used to verify skid alignment
(when a standard level is used, the length should be appropriate for the
skid). If assembling multi-component support stands, attach sections
using the supplied bolts through the tank frame mounting plates. These
should be hand tight until all of the piping is assembled. Note: skids are
leveled at the factory using a laser level.
5. Connect the piping between the skids by matching the union connections
and/or fl ange stamps and tightening. Refer to the mechanical drawing
as necessary to confi rm location of spool pieces etc. as the fl ange stamps
are shown on the drawing in hexagonal callouts. The fl ange stamps
should matched and aligned (the fl ange stamps should be directly across
from one another. Rotating a fl ange will result in piping misalignment).
Bolts should be hand tight until all of the piping is assembled. Refer to
the appropriate instructions to tighten the fl anges to the required torque
specifi cations. Support pipe runs as required.
6. Ensure that a low point drain is installed in the piping.
7. Connect the conduit runs between the skids and tighten conduit
connectors.
8. Locate the supplied wiring for the equipment and pull wiring through
the appropriate conduit runs. Electrical wires are labeled for easy landing.
Connect all wiring per the Fulton supplied electrical drawings.
9. If a header is supplied, mount the header as shown in the mechanical
drawing.
NOTE: For piping supplied in sections, make up and connect hand tight until all
sections are in place to ensure sections align properly. Sections are match marked
for reassembly.
10. Tighten all connections.
11. Pneumatically test the piping (at 15 psig maximum) prior to fi lling the
systems.
12. Check bolts and connections for tightness after the fi rst heat up cycle.
Retorquing may be required.
Stack and Flue
An appropriately sized stack should be connected to the fl ue gas outlet at the
boiler. The proper fl ue size and draft control is most important for proper burner
operation. See Table 4.
Stack and chimney must be constructed from material that is rated for 1000 F
