Step 24
Apply jacket rear insulation and jacket rear panel (temporarily) and install supply and return manifolds
Use of an approved dust respirator is strongly recommended when handling the insulating components of the boiler.
1. Insert and drive in the jacket front studs
(nine locations).
2. Press jacket front insulation over the
four boss tappings (foil side out).
3. Position the jacket rear panel over the
tapped boss or four boss tappings and
use a single nut to temporarily fasten
the panel in place. Finger tighten the
nut only.
4. Use a knife to cut the insulation at the
supply and return openings.
5. Use pipe dope and pipe tape on
threads of supply and return manifolds
and install in 4 inch rear tappings.
Mount return manifold (fi gure 7) with
drain valve in bottom position.

Step 25
Hydrostatically test the boiler
DO NOT exceed the test
pressure specifi ed here by
more than 10 PSI
.
DO NOT leave boiler
unattended. Excess
pressure could develop,
resulting in severe damage
.
Repair all leaks at once. If
block leaks should occur,
repair if possible. Contact your
representative for instructions
if necessary.
1. Apply blanking fl anges and gaskets to
the 4 inch fl anged supply and return
connections at the boiler rear.
2. Apply pipe dope and pipe tape to the
two 3 inch recessed plugs and install
in the front section (top left and lower
right). Driver is supplied with boiler.
3. Plug any unused openings in the boiler.
4. Pipe a shut-off valve to one of the top
tappings for bleeding air during fi ll and
drainage.
5. Remove the boiler drain valve from the
return manifold.
6. Pipe a shut-off valve, water supply
and drain line to the boiler drain valve
tapping.
7. Fill the boiler (bleeding air from top
valve) completely with clean water.
8. Use a hand pump or other means to
raise the water pressure in the boiler to
150 PSIG.
9. Close valves and observe the pressure
gauge for at least 10 minutes to ensure
the boiler is pressure tight.
10. If pressure drops, perform a thorough
inspection to locate the leak.
11. Repair any leaks found before
proceeding.
12. Once hydrostatic test is successful, drain
the boiler completely.
13. Remove the temporary piping.
14. Re-install the boiler drain valve.
15. Install the boiler relief valve in the fi rst
tapping on the top rear of the boiler.
