Dual Fuel
   Adjustable temperature settings determine the length of time that 
the heater will operate at maximum BTU to achieve desired temperature,
not the actual flame height. 
During first seasonal use, gas smell is expected to be more noticeable than in 
standard operation.
Operation Notes:
To stop the heater, shut off the safety valve on the gas inlet line.  Then, 
turn the heater’s Gas Valve Button to the OFF position.
Shutdown Process:
5.  The heater will now operate normally. You should adjust the Control     
   Knob to your desired heat setting. Room temperature will vary based    
   on individual room size and installation.
4.  Once the pilot flame is stable, turn the Control Knob counterclock   
   wise      from the Pilot setting to the desired number setting. This      
   should be done slowly in one motion, without stopping between 
   positions. Knob will only turn if you have a stable pilot light.
3.  Release both buttons.  Should the pilot go out, repeat steps 2 and 3.
2.  With the Control Knob set to Pilot, push down on both the Igniter     
   Button and the Control Knob simultaneously until ignition can be     
   heard. Continue to hold down both buttons for at least 15 seconds,   
   until the pilot is touching the thermocouple and is noticeably       
   heated.
1.  During the first seasonal operation, set the Control Knob to Pilot, then    
   hold down on the Control Knob for 3-5 minutes. This allows the air in the   
   manifests to clear completely. During normal operation, you will only    
   need to hold the Control Knob down on Pilot for about 5 seconds
Ignition Process:  
 Follow these steps to ensure that your heater 
is running the right way, every time.
