These are some of the configuration data that I 'embed' at the top of the source file to inform the programmer which fuses to set. This, of course, is for a PIC16F917. You will need to check which fuses apply for the 819 and set them accordingly.

Code:
@  device  pic16f917
@  device  INTRC_OSC_NOCLKOUT,WDT_OFF,PWRT_ON,MCLR_OFF
@  device  PROTECT_ON,BOD_OFF,CPD_ON,IESO_OFF,FCMEN_ON

define     NO_CLRWDT    1
define          OSC     4       ' OSCCON defaults to 4MHz on reset
