8. With the burner out, the tank underside should
be checked to ensure that the black emissivity
coating is still intact. There should be no shiny
stainless steel of the tank exposed, or white
substance. Remove any loose coating.
NOTE:
If touch up or recoat is required, use a spray can
of matt black high temperature enamel (VHT-1200
or equivalent) to re-coat the affected area.
9. Hold the new burner with one hand on the
underside of burner and the other holding the
throat, push up the rear of the burner until it
locates on the rear support bracket within the
burner box. It is good practice to have a good
look at this bracket before trying too install the
burner so that you can visualise where the
bracket is, when fitting the burner.
10. Once the rear of the burner is supported, the
front can be pushed up into its location. The
small notch in each side of the venturi, visible
externally from the burner body, is for the front
to back location and should be located up
into the top corner panels when pushing up
the burner at front.
11. To fit the burner box underside panel, push up
the rear of the burner box panel until it locates
on the rear support bracket within the burner
box.
12. Locate the corner support bracket. If the burn-
er is correctly fitted the corner support bracket
will align with the screw securing holes, secure
the corner support bracket in place with 4
screws. If corner panel will not align, check the
burner is located correctly.
13. Re-wire the rear of the burner to the rear
support bracket.
14. Relocate the pilot mounting panel and secure
the panel and the underside burner box panel
in position with 6 screws.

panel from underside of burner intake throat
from the side which burner is to be replaced.
6. Remove the burner box underside panel from
side on which the burner is to be replaced, by
