OUNTING THE BURNER DOOR
IMPORTANT:
Before mounting the burner door, make sure that its
gaskets and insulation are in excellent shape.
If any signs of damage or ageing are present, these
parts must be replaced.
The burner door must be mounted back on the heat
exchanger as follows:
- Place the burner door with its holes over the six
threaded studs.
Careful! When handling too rough or misplacing
the holes over the threaded studs, the burner door
insulation and/or gaskets can be damaged.
Ensure that the door is well positioned with respect
to the threaded studs, before pushing it onto the
exchanger.
- Keep the burner door firmly in place by pushing the
gas/air premix manifold with one hand at the mid-
dle at point A.
- Hand tighten the flange nuts with the other hand as
far as possible onto the threaded studs.
Now the burner door is in place and the nuts can be
tightened with a torque wrench.
-
Tighten the nuts in the order given in the pic-
ture
-
The specified torque value for tightening the
burner door flange nuts is
8 Nm
Tighten in given order.
torque value = 8 Nm
