STEP 4: POSITIONING OF THE UNIT
Place the firebox into position on top of the sheet metal.
Remember to leave a 25mm air gap on all sides of the firebox.
(If an outdoor air-kit is to be connected please leave a 125mm
air-gap at the rear of the firebox).

MASONRY BRICK INSTALLATION
STEP 5: OUTDOOR AIR KIT
(IF NOT REQUIRED GO TO STEP 6)
Any depression or lack of fresh air within the room where the
fireplace is located can result in emanation of smoke to flow
back into the room and for the unit to run inefficiently. It is
highly recommended that an Outdoor Air Kit be installed in 6
star or more rated homes, or any install where a mechanical
device (ie. fan), takes air from the fireplace cavity & transfers it.
STEP 6: FIRST LENGTH OF FLUE
Place the first single skin length of flue (with no crimp ends)
around the outside of the spigot. You may also use a heat
resistance sealant (i.e. Firecork) to seal any air gaps. Before
installing the remaining lengths of flue please continue to the
next step.
