Please note that these dimensions (based on Masonry margins) are the absolute minimum sizes - widths (A & B) maybe
increased if desired.
If you intend on recessing the firebox, please add the recess value to Dimension ‘B’. MINIMUM RECESS = 40 / MAXIMUM
RECESS = 100mm
It is important to ensure the Jetmaster firebox is seated at the required finished floor protector level.
DO NOT COVER AIR VENTS WITH MESH - as this reduces air flow, use specific external air vent covers that provide sufficient
air.
Allow 5mm gap around all four sides of the firebox to fit the Stainless Steel Weather Cover. i.e. do not plaster
up to the flange of the firebox, see Fig 4.
