11.0 BOILER START UP AND OPERATION

 

    

11.1 START UP PROCEDURE 

  Prior to start up make sure the service switch is in the OFF position. 

 

  Check all fittings and wiring. 

 

  Insure that the boiler and the entire heating system are completely filled with water and that 

all air has been purged from the system resulting that proper system pressure is achieved.  
The minimum PSIG is 12. 

  Check to insure that clean quality #2 heating oil has been used to fill your storage tank. 

 

  Open all manual shutoffs throughout the system. 

 

  Set operating controls to the recommended settings. 

 

  Follow  the  manufacturer’s  instructions  for  proper  light  off  and  setting.    Using  accurate 

combustion test equipment set the burner for proper “steady state” operation.  The use of 
accurate instruments is necessary to achieve maximum efficiency and lowest fuel costs. 
 

  Adjust the thermostat to manufacturer’s instruction 

 

  Place this manual, the control manual and the burner manual along with related consumer 

information in an easily accessible location.  Installers should make the consumer aware of 
the content and location of this information. 

 

    

11.2 Honeywell L7248 Aquastat  

 

Adjusting Settings  

To  discourage  unauthorized    changing  of  Aquastat  
settings,  a  procedure  to  enter  the  ADJUSTMENT 
mode
 is required. 
 
To  enter  the  ADJUSTMENT  mode,  press  the  UP, 
DOWN 
and button simultaneously for three seconds.  
Press  the  I  button  until  the  feature  requiring 
adjustment is displayed. 
 
Then  press  the  UP  and/or  DOWN  buttons  to  move 
the  set  point  to  the  desired  value.  After  60    seconds  
without    any  button    inputs,  the  control    will 
automatically  return to the  RUN mode  and lock the 
setting.
