Regading new connection

Dear sir,

Is it compulsory to purchase new gas burner from same gas agency along with new connection?

I had subscribe the new connection in pune recently for which that gas agency force me to purchase new gas burner (of his own choise of brand and type) from him along with 2 kg of rice. Is it compulsory? he told me so.

And if so why we should not get choice of brand, style, and color.
