HINTS ON GAS FIRING CONTROL 

 

CONTROLLING  THE  GAS  FIRING  OF  YOUR  LOCO  MUST  BE  DONE 
WITH  CARE  AND  ATTENTION.  TURNING  THE  FIRE  UP  TOO  MUCH 
CAN  CAUSE  GREAT  DAMAGE  TO  YOUR  MODEL  SUCH  AS  BURNING 
OFF THE PAINT, MELTING THE INSULATION OFF THE WHEELS, AND 
CARBONIZING  THE  STEAM  OIL  IN  THE  SUPERHEATER  WHICH 
BLOCKS  IT.  NONE  OF  THE  ABOVE  DAMAGE  WILL  BE  COVERED  BY 
WARRANTY AS IT IS ATRIBUTED TO OPERATOR ERROR. 
 
AT ACCUCRAFT WE GIVE YOU THE ABILITY TO RAISE A GOOD HEAD 
OF  STEAM  BUT  IT  IS  UP  TO  THE OPERATOR  TO  CONTROL  THE GAS 
FLOW  SO  THE  FIRE  DOES  NOT  ROAR  OUT  OF  CONTROL  AND  BURN 
IN THE SMOKE BOX. IT IS VERY MUCH LIKE THE ACCELERATOR OF 
YOUR  CAR,  HOW  YOU  USE  IT  IS  UP  TO  THE  USER,  DRIVE  SENSIBLY 
AND  YOU  WILL  NOT  HAVE  AN  ACCIDENT;  PUT  YOUR  FOOT  DOWN 
AND  YOU  WILL  PROBABLY  END  UP  IN  THE  HEDGE.  HARDLY  THE 
CAR OR THE MANUFACTUER’S FAULT!  
 
NEVER  LEAVE  THE  LOCO  UNATTENDED  WHEN  RAISING  PRESSURE, 
AS  THE  HEAT  INCREASES  THE  PRESSURE  IN  THE  GAS  TANK  ALSO 
RISES  AND  YOU  WILL  HAVE  TO  TURN  THE  GAS  DOWN.  IF  THE  GAS 
CONTROL  VALVE  SPINDLE  IS  A  BIT  STICKY  IT  COULD  NEED 
LUBRICATION WITH STEAM OIL. WHEN YOU UNSCREW THE NEEDLE 
VALVE TO OIL IT ALWAYS DO IT WHEN THE GAS TANK IS EMPTY.
