CONNECTING FLUE SYSTEM
Consult the flue installation guide supplied with the flue kits for detailed flue installation instructions. For connection
of the flue to the heater refer information below.
Removing the pipe clamp, extension tube and exhaust pipe
Before installing the heater into the enclosure the pipe clamp, telescopic extension tube, and exhaust pipe need
to be removed so there is room to connect the flue system.
1. Undo the pipe clamp and remove the telescopic extension tube from the exhaust pipe.
2. Secure the telescopic extension tube to the flue system with the exhaust pipe lock.
3. Attach the air hose to the flue transition and secure with the cable tie provided.
Please note that in the adjacent image in step 4 the air hose is already connected to the flue. It is much easier to
connect the air hose to the unit than to connect the air hose to the flue once the heater is in place. Ensure the air
intake hose of the heater is properly secured to the air connection on the flue system using the cable tie provided,
and that the rubber seal is placed on the unused air intake connection.
The exhaust pipe lock is provided with the ASPDFK and ASPKIT03 flue kits
Flue transition (ASPDFK, ASPKIT03)
The flue transition provides a connection between the flue system and the heater's flue spigot and air intake.
For all flueing installations, except horizontal direct flueing, the flue transition is counted as a 90 ° bend. The
flue transition requires a 5 mm clearance from combustibles. This clearance is provided automatically when the
supplied standoff brackets are used. All other flue components, except the elbow section of the ASPKIT03, are
designed for zero clearance and can be placed hard against timber or plasterboard.
