10. For installation into a non-combustible fireplace, i.e.: masonry or brick
or into a mock fireplace, i.e. timber or plasterboard, the chimney and
base should be of sound construction and be free from cracks and
holes (to ensure that sufficient flue draught can be generated).
Note: when installing into a mock fireplace a mock fireplace
installation kit must be used.
11. The heater must be properly installed in a working chimney or con-
nected to a venting system. Operation of this heater, when not con-
nected into a working chimney or a properly installed and maintained
venting system can result in carbon monoxide (CO) poisoning and
possible death.
12. Testing the effectiveness of the flue.
Before testing the flue confirm air vents are unobstructed. If an exhaust
fan or other heating appliances are present switch them on. This is to
test that there is no interaction between the Cannon heater and other
appliances.
Refer AS5601.
