Can I use a Vivitar 285 hv Flash (the older model) on a Canon Rebel digital XSI? - canon hv

I have a Vivitar 285 HV flash, and it intends to use on my Canon Digital Rebel, but I'm afraid that can fry the shoe camera. No one could use the device and still okay? Please, please let me know, I have thought for a long time to get this camera, and I really wanted not to spoil. Make sure your answers. and thanks!
