INSTRUCTIONS – AERCO HELITHERM STEAM GENERATOR MODEL SS1B-PLUS
SG-101-5
INSTALLATION
1. Dimensions for an AERCO Steam
Generator Model SS1B-PLUS are shown in
Figure SG-101-1.
2. Uncrate the Generator carefully. Set it
upright by using a block and tackle or hoist
attached to the lifting lugs on the top head of
the Generator (the eye bolts shown in Figure
SG-101-9). Always use the lifting lugs to lift
and/or move the Generator.
3. If possible, for easy in-place maintenance,
locate the Generator where there is at least
2 feet clearance all around the unit and
where the head room clearance is equal to
or more than dimension C in Figure SG-101-
1 for the size Generator furnished.
4. It is suggested that the Generator be
secured to the floor. However, any other
means for securing the Generator may be
used. If piping is used to secure the
Generator, the piping must include ample
provision for expansion.
5. Make all piping connections as instructed in
Step 6 below and in accordance with Figure
SG-101-2 or with any specific piping
diagram which may have been furnished by
AERCO for this installation.
6. For best Generator performance, observe
the following very carefully in making the
piping installation:
a. Do not use cement or red lead in
making up pipe joints.
b. For Generator connection types, sizes,
and locations, see Figure SG-101-1.
c. All piping to the Generator top head
should be provided with unions or
flanges which are located beyond the
outside diameter of the Generator head
to permit removal of the head and
she!1for in-place maintenance.
d. Include all of the stop valves, check
valves, steam traps and other elements
in the piping as shown in Figure SG-
101-2 or as separately specified by
AERCO. Note that the steam trap and
Generator drain valve are included in
the Generator assembly.
e. Be sure to include a vacuum breaker in
the steam outlet line ahead of the stop
valve. This assures no vacuum buildup
during operation.
f. The condensate return piping should be
arranged to permit condensate to drain
freely by gravity from the Generator
bottom head. Failure to do so may result
in Generator improper operation and/or
in damage to the primary
steam/condensate system.
g. All drain discharges -- relief valve in the
top head of the Generator and drain
valve in the bottom head -- should be
piped directly to a convenient floor drain.
7. Before making final piping connections to
and from the Generator, blow out all piping
thoroughly.
8. Make the necessary air-operated Control
Valve supply air connection to the connector
through the side of the control box. THE
SUPPLY AIR PRESSURE MUST BE
MAINTAINED AT 25 PSIG.
9. Connect 110V 60 Hz power supply wiring
through the side of the control box to the
electrical junction box.
