START-UP TEST RUN
Refer to the OPERATION section, pages 9 – 11 for more information.
WARNING: THE GAS STEAM BOILER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING,
CLEANING, OR SERVICING THE BOILER.
After the gas steam boiler is installed and proper service connections have been made, thoroughly test
the boiler before operation.
1. Turn knob of gas valve counterclockwise to on.
2. Be sure the water inlet valve is open. Close only for service or long shutdown.
3. Locate the power switch and press [ I ] to start. Two indicator lights (Low Water and High Pressure)
become lit as water fills the boiler. After about 4 – 5 minutes, the water will reach the required level
in the boiler and the green indicator light on the reset switch is lit.
4. Observe the water level gauge sight glass to verify the water level.
• Keep both valves on the water gauge open at all times.
5. Press the reset switch with green indicator light lit to light the boiler.
6. Both Low Water and High Pressure indicator lights must be off before the burner will ignite.
• If the indicator lights do not go off after 15 minutes or if they come on during normal operation,
press [ 0 ] for off and contact an authorized Vulcan-Hart servicer.
7. If the burner does not ignite after 30 seconds press [ 0 ] on the power switch for off, wait 5 minutes,
then repeat steps 1 – 5.
• If the ignition does not occur after 3 tries, press [ 0 ] on the power switch for off and contact an
authorized Vulcan-Hart servicer.
8. Steam generation will begin in about 10 minutes.
• Observe that the boiler pressure gauge indicates steam pressure in the range of 8 – 12 psig.
9. To shut down the boiler, press [ 0 ] on the power switch on the boiler (Fig. 2).
• Indicator lights are not lit.
• Boiler will automatically blow down.
AUTOMATIC BLOWDOWN
When [ 0 ] on the power switch on the boiler (Fig. 1) is pressed, the boiler will blow down for
approximately 5 minutes.
SEQUENTIAL START-UP
After the boiler is operating and producing steam, start-up the farthest away piece of equipment until
it is preheated and 'up-to-temperature' before starting the next piece of equipment. It is recommended
that all kettles be started before any compartment steamers. This will allow the largest pieces or the
most difficult to warm up equipment to be properly warmed up before smaller, nearer units which
require less heat. This will pervent the system from being overwhelmed by initial demand.
