back boiler units have to be installed with gas fire. Type in the make and model of the boiler in google and visit the manufacturers website, this will tell you what fire is required. It is dangerous and against the law to use a open flued back boiler without the fire front (have seen this before, where people remove the fire and cover the boiler with alternative decor)
