Installation tips
For installation into a masonry or brick fireplace WITH a flue connection, refer figure 7. For
installation WITHOUT refer figures 8 & 9. After installation of the heater test the flue to
confirm air vents are unobstructed. If an exhaust fan or other heating/ventilation
appliances are present, switch them on. This is to test and ensure that there is no
interaction between the Cannon heater and other appliances.
Refer to Australian Standard Gas Installations AS 5601:
For ‘air movement not to affect appliance’ see clause 5.3.1.
For ‘air supply to appliance’ see clause 5.4.1.
For ‘ventilation requirements’ see clause 5.4.3.
F1417 flue transition rectangular to 100mm round.
F2517 flue spigot is also required.
The flue must be rigid and self-supported. It is a
requirement that the heater has a slip flue
connection and can be removed without any
restrictions.

Flashing
Fit two lengths of vertical flue (1.8m) before fitting
any 45° bends. If bends are used, fit inside of flue
pipe. Use no more than two 45° bends in the total
flue run and maintain at least 250mm of straight
flue pipe between the bends.
Be careful!
Installing a flue on the shortest
wall may subject it to down
draughts or reverse air flows
through the heater which can be
difficult to find a solution to.
Always adopt correct flue design
practices.
In windy locations consider
installation of a powerflue
version heater or at least an anti
down draught cowl to reduce
any flue operation problems.
The heater has been tested and
should operate satisfactorily
with an optimum flue length of
4.5 meters.
Exceeding this length may affect
the stability of the flame pattern
and the operation of the heater.
Contact our technical support
department if any further advice
is required.

(in most cases only a single skin flue is required)
¡
Test the operation of the chimney before installing the new heater.
¡
Be careful!
CANNON heaters are high efficiency products with low flue
gas temperatures (typically 100°C) so if you are replacing an older type
radiant heater with a much higher flue gas temperature (150°C or higher)
make sure of the integrity of the fireplace and chimney before installing
the new CANNON log fire.
¡
A solid, levelled and smooth base is required (fill gaps with fibreglass
insulation if necessary).
¡
Avoid installing into large volume fireplaces and chimneys and not fitting a
flue. (It is better to install a flue in these applications).
¡
We recommend cleaning or sweeping the chimney and fireplace before
the installation of the heater commences.
¡
There must be a good seal around the heater, gas piping and electrical
cable rear entry to stop any leakage of combustion products. Do not use
adhesives or silicone sealant, the heater must be able to be easily
removed if necessary.
¡
Install a chimney plate and cowl to the chimney opening using weather-
proof mortar to common building practice.
¡
Remove any curved firewall that slopes too far forward to the fireplace
opening as it causes restriction to the flue path above the heater flue
outlet.
¡
Make sure that the heater is fully commissioned and be certain to conduct
a test of the integrity of the flue operation, taking into account any
influences created by rangehoods, exhaust fans, central heating, etc.
¡
To avoid any unnecessary delays and inconvenience to your customer
please contact or Technical Services Department on
1300 727 421
if the
installation is unusual or you have concerns with the installation and/or
heater operation before the installation commences.
¡
Any service requests resulting from incorrect installations are not covered
by our warranty conditions and these calls will result in charges, usually
to the end user, so please ensure that the installation and commissioning
has been satisfactorily carried out before calling for any warranty service.
¡
Please make sure that your customer is fully instructed on how to operate
the heater.
