REFIT COMPONENTS
1 Align burner combustion head (K) into boiler
housing tube with gasket (O) correctly fitted.
Push firmly down to compress the gasket (O).
Tighten burner retainers (H) sufficiently to
ensure a good seal.
IMPORTANT: Ensure the gasket is a good
seal between the burner combustion head
and the boiler housing to prevent flue gases
escaping from the combustion chamber into
the room.
Attach air duct pipe and tighten clip (J) to
secure to the burner air intake.
2 Refit the expansion vessel (D) onto the support
bracket (E) taking care not to kink the flexible
hose or snag the thermostat capillaries.
