Operation 

Main burner air supply:

 

  

1. For efficient burner operation, a proper balance of gas volume and primary air supply must be maintained 

which will result in complete combustion. Insufficient air supply results in a yellow streaming flame. 
Primary air supply is controlled by an air shutter on the front of the burner. 

2. Loosen the screws on the front of the burner and adjust the air shutter to just eliminate the yellow tips of 

the burner flame. Lock the air shutter in place by tightening the screws. 

 

CAUTION

 

The space between the legs at the bottom admits combustion air. DO NOT BLOCK THIS SPACE. 
  
All burners are lit from constantly burning pilots. Turning the valve to the desired flame height is all that is 
required to put the unit in service. 
  
Do not permit fans to blow directly at the unit. Wherever possible, avoid open windows next to the units' sides 
or back. Avoid wall type fans which create air cross-currents within a room. 
  
It is also necessary that sufficient air should be allowed to enter the room to compensate for the amount of air 
removed by any ventilating system. Otherwise, a subnormal atmospheric pressure will occur, affecting 
operation and causing undesirable working conditions. 
  
A properly designed and installed hood will act as the heart of the ventilating system for the room or area in 
which the unit is installed, and will leave the unit independent of changing draft conditions. 
  
All valves must be checked and lubricated periodically. This must be done by an authorized service 
representative in your area. 
  

Note:

 

Please wait at least 15 seconds to restart the main burners to maintain the best function of the thermostat 
valve after turning off the main burners. 

 
 

IMPORTANT

 

  

Should any abnormal operation like;

 

- ignition problems, 
- abnormal burner flame, 
- burner control problems, 
- partial or full loss of burner flame in normal operation, be noticed, the appliance requires IMMEDIATE 
service by a qualified service person and should not be used until such service is carried out.
