e) Allowance must be made for expansion of both the pipework and the generator;
especially if the pipework is rigidly fixed in any place other than adjacent to the safety
valve.
f) All open ended pipes are to be suitable secured to ensure that no movement (other than
expansion) can be caused by the action of steam discharge from that pipe.
g) In cases where multiple generators are to be installed, a header incorporating a steam
trap must be provided. In all instances where generators are connected in parallel with
another steam boiler, it is the responsibility of the customer to comply with Local
Authority, Insurance Company, Factory Act and Health & Safety at Work Act
requirements. These requirements are concerned mainly with maximum pressure, water
contents, safety valves, piping sizes etc.
27. The Blow-Off Valve
a) There are two blow off valves on the Steampac: The main valve and the water gauge
glass blow off valve. The SteamPac blow off valve supplied with the boiler should be
screwed to the blow off pipe and connected to a blow off receptacle of approved design.
This should be done in accordance with state and local codes.
28. The Feed Water Piping
a) Provisions must be made for adequate water supply and properly sized piping. Piping
must be done in compliance with all local codes.
b) When feeding the SteamPac using a return system, the city water pressure should not
exceed 40 PSI. A pressure reducing valve should be installed a head of the return tank
when above this pressure.
c) It is important that all piping be lined up and not forced into place. It is recommended that
you begin piping at the pump. If the lines are ended at the pump, particularly if the last
piece is cut too short or too long, the pump will be forced to meet the pipe and strain or
distortion will result.
d) Do not use the pump as a piping support. It is critical that the pipe be independently
supported near the pump so no strain will be transmitted to the unit.
e) Connect the feed water stop valve to the feed water pipe and pipe it to the return
system.
29. The Steam Supply
a) Pipe the steam supply line from the steam outlet.
