9.0 Maintenance of The Rangitata ULEB
Further sections will describe the systematic process of carrying out regular and periodic maintenance and
servicing of different parts of the firebox, and flue. Replace parts only with genuine GLEN DIMPLEX spare
components:
9.1 Ash Removal
Ash removal is necessary when the ash level is up to the lower door opening. Before carrying out ash
removal, make sure that the burner is cold and there are hot embers in the firebox. Simply shovel out
any excess, leaving a 15-20mm bed of ash in the firebox. Place the removed ashes innon-combustibleble
container with a tightly fitting lid, and move the container outdoors immediately to a place clear of
combustible materials.
9.2 Cleaning the Glass
A good hot fire will burn away any deposits left from a long slow burn. A dampened newspaper with
ash or a non-caustic oven cleaner can be used to clean the glass.
9.3 Cleaning the Fascia
A soft rag is sufficient to clean and maintain the finish of the panels. The household detergent may
damage painted panels or give bad odors while running the fire.
9.4 Adjusting the Door Latch
- Open the main fuel loading door
- Remove the grub screw pin from the bush, which is on the inner side of the door, just above the door
spindle.
- This screw stops the full rotation of the handle.
- Wind the door handle in or out depending upon whether you want to loosen or tighten the door seal.
- Sandwich a piece of paper between the firebox edge and the door seal to check the door seal.
- Close the door and try to pull the piece of paper.
- The paper will be jammed or will slide with effort when the seal is good or sufficient.
- Carry out this test on all four sides of the door to ensure the seal is even on all sides.
9.5 Door and Door Glass Seals
Door seals of the main door should be checked and, if required, will need replacement periodically depending
upon the usage of the Rangitata burner. Over the period, the door and glass seals will become hard and
cause air leak into the firebox. This excess air can lead to the 'over-firing' of the burner and damage the burner
parts. If any part of the burner or flue system is glowing, the burner is being over-fired.
9.6 Heat Output Control (Air Slide)
If the air slide does not move freely, have an installer inspect the unit and apply a small amount of
heat resistant air slide lubricant, available from Glen Dimplex
9.7 Firebox Masonry Bricks
The masonry bricks in your Rangitata burner are an essential part of the burner to achieve clean and efficient
burn. These bricks are likely to degrade with time and will need to be replaced accordingly. The life of the
bricks will depend upon usage, type of fuel burnt, and care taken during operations and maintenance. The
bricks are held in place using the brackets screwed to the firebox sides and the rear. Due to the high
temperature in the firebox, the bricks may crack with use, and this is regarded as normal. If the bricks crack
but remain in place, it will not affect the performance of the fire and subsequently can continue to be used.
The bricks should be replaced only when they are damaged enough in place and cannot perform their intended
task. Refer Fig 6.1 for location and sequence of assembly of bricks in the firebox of the Rangitata burner.
