HIGH EFFICIENCY DECATHLON (HD) SERIES GAS FRYERS 

CHAPTER 4:  FRYER OPERATIONS 

 

 

4-3 

4.1.2  Pilot Lighting Procedures, Electronic Ignition Systems

 

 

 WARNING 

Never use a match or taper to light pilot on this ignition system. 

 
 

1.

 

Turn gas "ON". 

 
2.

 

Turn electric power "ON" with the appropriate rocker switch or controller/computer. 

 
3.

 

The ignition module will energize the pilot gas supply and the igniter. The igniter spark will 
ignite the pilot gas.  The presence of the pilot flame is then proved by a flame sensor, which 
sends a signal to the main gas supply, opening the valve. The operating thermostat or 
computer/controller controls the fryer after ignition. 

 
 

 WARNING 

In the event of prolonged power failure, the ignition module will shut down and lock 

out the system.  Turn the unit power "OFF" and then back "ON" after power has been 

re-established. 

 

4.

 

If the pilot flame fails, the ignition module will shut down and lock out the system.  To restart, 
turn the electric power "OFF", wait approximately 5 minutes for the system to recycle itself, and 
then turn the power "ON" again.  Repeat Steps 1-3. 

 

 
4.2 Boil-Out Procedure 

 

 DANGER 

Never leave the fryer unattended during the boil-out process.  If the boil-out solution 

boils over, turn the fryer off immediately and let the solution cool for a few minutes 

before resuming the process.  To lessen the chance of boil over, turn the fryer’s gas 

valve knob to the PILOT position occasionally. 

 

 WARNING 

Do not drain boil-out solution into a shortening disposal unit, a built-in filtration unit, 

or a portable filter unit.  These units are not intended for this purpose, and will be 

damaged by the solution. 

 

 DANGER 

Remove all drops of water from the frypot before filling with cooking oil or 

shortening.  Failure to do so will cause spattering of hot liquid when the oil or 

shortening is heated to cooking temperature and may cause injury to nearby 

personnel.
