9.8 Secondary Air Tubes Removal
There are two air tubes in the Rangitata ULEB burner fitted with a removable "R" clip, on the left-hand side
of the firebox. To remove the air tube, remove the "R" Clip and move the tube to the right. This will remove
the tube from the left-hand side of the firebox. Then push down and tilt the left end to release the tube
from the right end of the firebox. Maneuver the tube out of the firebox once released from both ends.

9.9 Firebox Baffle
- The steel baffle used in Rangitata ULEB has two sections. For flue cleaning or baffle replacement, the
secondary air tubes must first be removed as described above.
- First, pull forward the front baffle slightly and then push it to one side so that the baffle is off the other side
support Keep dropping and tilting the other side to dislodge it entirely from the supports and then maneuver
the baffle out of the firebox.
- The rear flange of the rear baffle is engaged behind the side supports. So first lift it at the rear and slightly
move it forward. Use the same technique if moving to one side, then dropping, tilting to dislodge from the
side supports, and finally maneuver out of the firebox.
- For replacing the baffle, reverse the steps mentioned above, starting with rear and then the front
baffle.
- Make sure that the rear flange of the rear baffle is tucked behind the side supports and hard against
the back wall fo the firebox. Also, ensure that it is sitting on top of the
supporting shelves on both sides
of the firebox
- The front baffle is pushed back hard against the front of the rear baffle.
- Check that both the baffles are locked and hard up against the rear wall of the firebox.
9.10 Flue Inspection & Cleaning
Flue system should be checked at least once a year depending upon usage and, if needed, be swept by a
professional chimney sweep. Do not use chemical chimney cleaners. Check the flue sections nearest the
firebox. If a flue system is becoming excessively blocked or needs frequent cleaning, investigate the installation,
fuel, and operation of the burner with the help of a professional.
Refer section 9.6, 9.7 & 9.8 for removing bricks, air tubes, and baffle. This will enable to drop and collect all the
chimney dirt into the firebox without removing the main flue pipe. Once chimney sweep operation is complete,
clean the firebox chamber properly and put back both front & rear baffle, both the air tubes and the bricks.
