Lesi sishisi sikadoti sisetshenziselwa ukubhekana nemfucuza yezokwelapha, njengenaliti nesipetu ngaphansi kwezinga lokushisa eliphezulu.Futhi isishisi singashisa izitho zezilwane ezilahlwayo.

Isishisi sikadoti wezokwelapha sinezinzuzo eziningi:

1. Isishisi sikadoti wezokwelapha singabhekana nemfucuza yezokwelapha ngokushesha esibhedlela futhi sihlanganisa indawo encane.

2. Ukufakwa okulula, ukusebenza okulula, ukugcinwa okulula.

3. Intengo evumayo ngempilo ende.

4. Vikela imvelo, ukuphuma kwe-exhaust ngaphandle kwentuthu emnyama esobala, akukho phunga, akukho uthuli lwezinhlayiya ezinkulu.

5. Izinga lokushisa eliphakeme kakhulu lingafinyelela ngaphezu kwama-degree angu-1600.
