4. OPERATING INSTRUCTIONS
• Before Starting
 Make Sure that Boiler Feed Water is:
a) Hardness < 5 ppm
b) pH 8.5 to 9.5
c) Oxygen Nil
 Fuel Viscosity 5 to 10 CST
 Ensure that the steam temperature controller setting is not altered. The knob
pointer should be set 10 Degree Celsius above saturation Temperature of Steam.
 Ensure Drain Valve of Economizer is closed.

5. • Sequence Of Operations: STARTING
 Open the valve on Water supply Line
 Put the Electric Main Switch on . Observe White Control lamp comes On.
 Put the Fuel Heater switch on to start fuel Pre-heating. (For FO)
 Close the main steam valve and open vent valve to prevent water entering process
steam line.
 Put the knob on FILL position to fill up the coil.
 When the water starts coming out of vent and required fuel temperature is
reached unit can be fired. Put the knob on FIRE position.
 Green BURNER ON lamp comes on , fuel Spray Starts and Flame is Established.
 After 3 to 5 minutes steam is seen coming out of vent. Open the main steam valve
and close the vent valve

6. • RUNNING ATTENTION
 TEST water Hardness. BOILER SHOULD NEVER BE WORKED WITH HARD
FEED WATER.
 Observe for any abnormal sound or any Leakage.
 The flame should be steady and Golden Yellow in color. Reddish flame
Indicates that the combustion air is insufficient.
 Exhaust from the chimney almost colorless
• Sequence Of Operations: STOPPING
 Close the steam stop valve completely .the pressure switch will cut off the
Boiler
 Put the switch on OFF position
 Put off the Heater Switch
 Put off the electric main switch
 CLOSE the outlet off soft water service tank and fuel oil service tank

7. DO’S AND DON’TS
• WATER SYSTEM
 Feed only soft and suitable water to the Boiler. NEVER feed Hard Water as this will
result in scale Formation and choking up the coil.
 NEVER run the water pump with insufficient or incorrect lubricating oil.
• FUEL SYSTEM
 Never run fuel pump dry.
 Use fuel additives for Improving combustion
 NEVER set the point of the fuel Temperature controller above 130 deg Celcius
 Ensure supply of clean filtered fuel.

8. REMEMBER
BOILER IS A CRITICAL
EQUIPMENT,ANY
NEGLIGENCE CAN COST
YOU YOUR LIFE
BE SAFE ALWAYS 
