17.     OPERATION AND SERVICE

 

 
OPERATION: 
 
Before operating the boiler, the entire system must be filled with water, purged of air and 
checked for leaks. Do not use Stop leak or other boiler compounds. The gas piping must also 
be leak tested. 
 
Any safety devices including low water cutoff, flow switch and high limit used in with this boiler 
must receive periodic inspection (every six months) to assure proper operation. A low water 
cutoff of the float type should be flushed every six months. All relief valves should be inspected 
and manually operated every six months.   
 
For your safety follow the lighting and operating instructions below and on the boiler. 
 
To turn on main burner, slowly open firing valve after pilot is established. 
 
Set primary system controller to desired temperature. 
 
To turn off boiler close main manual gas valve, close pilot manual valve and turn off electric 
power to system. 
 
SERVICE: 
 
Disconnect main power and turn off gas supply before servicing unit. 
 
To remove and clean the burner, follow the detailed procedure in section 15 of this manual 
 
After the first season of operation inspect the heat exchanger and venting . Follow the detailed 
instructions in section 6 of this manual. 
 
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can 
cause improper and dangerous operation. Verify proper operation after servicing. 
 
Any audible sounds in the equipment, like pinging, crackling or hissing are indications of scaling 
or lack of sufficient water flow. Under these conditions the boiler must be shut down immediately 
and the heat exchanger checked for damage. If the exchanger is damaged from scaling, it is not 
covered by warranty. 
 
Should your equipment be subjected to fire, flood or some other unusual condition, turn off all 
gas and electrical supply. if you are unable to turn off the gas , call your gas company or gas 
supplier at once. Do not put the unit back in operation until it has been checked by a qualified 
agency to ensure that all controls are functioning properly. 
 
Units that are not operated for a period of 60 days or more are considered seasonal operations. 
It is recommended that before returning one of these units to service, the proper operation of all 
controls be checked by a qualified service technician.
