Phil,
Thanks for your reply.
Actually I have set the option in admin "Manufacturers list limit (leave empty if unlimited)" - 10
So it just displaying 10 manufactures only when I insert your above code.
I have around 2500 manufactures & it's not good idea to show all of them in one page. And that's the reason I required to give option to search manufactures also.
Any other possible way to allow customer to search manufacturer quickly ? I am already using http://www.websitecm.com/news/new-x-cart-mods/new-x-cart-module-manufacturers-a-z-for-xcart/ mod to display manufactures more effectively.

Also I am using your very effective nice little cool mod http://www.xcartmods.co.uk/x-cart-filter-by-manufacturer.html
