For gas fire spares, eg coals and embers try The Spares Merchant. I found them simply by "googling" gas fire spares. In my limited experience they are an excellent Company who take pride in their customer service levels.
Hi All - I am also trying to find the manual for the Streamline 2, in my case to get sign off on a gas safety check for our house. Do any of you have a copy - I've tried sirocco fires by e-mail, but no joy yet. E-mail is firstname.lastname@example.org. Thanks!
