INSTALLING THE APPLIANCE
When an existing refractory fire back (chairbrick) is fitted, care must be taken to ensure that the depth of the
opening is no less than 205mm from the front face of the surround to the front face of the chairbrick. This is to
ensure that no luminous flame extends beyond the front face of the opening. See fig. 2.
