CHEDULE

 

 
The Daily and Weekly observations can be done by operating personnel.  Monthly, Semi-Annually and 
Annually observations and any required adjustments, servicing, etc. should be performed by qualified 
service personnel. 

This schedule applies when the boiler is in use.  Local codes or jobsite conditions may require more 
frequent servicing.  Verify proper operation after servicing. 
 

  Proper lockout / tagout procedure must be employed when servicing this unit. 

 Label all wires prior to disconnection when servicing controls.  Wiring errors 

can cause improper and dangerous operation. 

 Use care when reassembling main gas line to assure all connections are tight. 

 Use care when servicing boiler in order to prevent the accumulation of gas in 

or around the combustion chamber. 

 Determine the cause of any lockout or errors before resetting the boiler.  If 

able to determine cause of lockout, then appropriate corrective action should be taken.  If unable to 
determine cause of the problem, call a qualified service technician. Verify proper operation after 
servicing. 

Verify proper operation after servicing. 

 

5.1.1 Daily 

Observe operating temperature and general conditions.  Make sure that the flow of combustion and 
ventilating air to the boiler is not obstructed.  Determine the cause of any illuminated red indicators, 
unusual noises or operating conditions and make the necessary corrections. Notify responsible 
individuals for required corrective action or repair. 

 Check daily to be sure that the boiler area is free and clear of any combustible 

materials, including flammable vapors and liquids. 

 

 

5.1.2 Weekly 

Observe the conditions of the pilot and main flame.  A normal flame is blue.  If the high fire flame is 
yellow or if it pulsates, or if the burner starts with a rumble or puff, corrective action must be taken by 
qualified personnel.
