Open the main fuel loading door
To adjust the tension on the door rope and have a good seal, the door catch pin can be moved
forward and back, loosen the securing bolt on the inside of the firebox, move the pin toward the rear
of the fire and re-tighten, repeat until a good seal has been achieved.
Testing the door seal while adjusting the spindle, Sandwich a strip of paper between the firebox edge
and Seal, pull the paper gently and as you do there should be a resistance on the paper, adjust the
Spindle until you are satisfied a good seal has been made. The paper will be jammed or 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.
Door and Door Glass Seals
The main door seal should be checked periodically and, if required, will need to be replaced. Over time
the door and glass seals will degrade and cause air to leak into the firebox. This excess air can affect
the performance of the burner and possibly cause damage to the burner components. Air leaks can also
cause blackening of the glass.
Heat Output Control (Air Slide)
The air control on the burner should move freely, if at any time this becomes sticky have a
service technician inspect and make the appropriate adjustments to free it up.
Firebox Ceramic Bricks
The ceramic refractory bricks in your Clutha burner are an essential component for achieving a clean
and efficient burn. These bricks may degrade/break or crack depending on usage, if cracks are visible
but the brick is still secure then there is no need to replace them but if they degrade significantly or fall
apart then they will require replacement. The bricks are held in place using the brackets welded to the
firebox sides and the rear see fig 3.6 for brick details of brick layout.
Baffle
- The stainless-steel baffle used in Clutha is made of thick gauge stainless steel, it has a rear air
intake chute, which needs to be fitted properly into the slot on the back wall of the fire. For flue
cleaning, this baffle must be removed as described below.
- First, pull forward the front baffle slightly to disengage the rear chute from the slot on the rear wall.
Then push it to one side so that the baffle is off the other side's support. Keep dropping and tilting the
other side to dislodge it entirely from the supports and then manoeuvre the baffle out of the firebox.
- For replacing the baffle, reverse the steps mentioned above.
- Check that the baffle is locked and hard up against the rear wall of the firebox.
Flue Inspection & Cleaning
The flue system should be checked at least once a year and be swept by a professional chimney sweep.
If a flue system is becoming excessively blocked or needs more frequent cleaning, investigate the
installation, fuel, and operation of the burner with the help of a professional. First, remove all the ceramic
bricks and the baffle. This will enable to drop and collect all the chimney dirt into the firebox without
removing the main flue pipe. Once the chimney sweep operation is complete, clean the firebox chamber
properly replace the baffle then the bricks baffle, both the air tubes and the bricks.
