7. ASSEMBLY OF BURNER RING AND BURNER
z
Make sure that the Burner Ring is set in
position, as shown in the figure.
It is
especially important that the three burner
side pins are all in secured position.
Care is to be given for the Primary Flame
Rod, when removing the Burner Ring.
8. BURNER MAT
z
After the Burner Ring is removed, the Burner Bottom is seen as illustrated in the below
figure. (See 7. Assembling of the Burner Ring and Burner)
This Burner Mat is
adhered to the bottom of the Burner with a heat resistive inorganic adhesive, which plays
an important role of preventing oscillated combustion.
z
The Burner Mat is normally made of a silica cloth (having a thermal resistance of
1000°C), which is not breakable under normal using condition. If replacing the Burner
Mat, first completely remove the Mat itself and adhesive by using a sand paper and apply
adhesive between the base and the new Burner Mat. (See page 27 for the details by
model.)
z
Also remove the carbon from the bottom of the Burner by using a vacuum cleaner.
