The primary heat exchanger baffles consist of one
heavy baffle stack (4mm thick) at the bottom, 3 lighter
baffle stacks (3mm thick) in the middle and 1 baffle
plate (3mm thick) at the top. Upon installation or after
servicing, ensure the baffles are in the correct order
and correctly stacked. To achieve maximum efficiency
push the primary heat exchanger baffles in the direction
of the arrows as shown. The secondary heat exchanger
spring baffles must be fully inserted into the heat
exchanger tubes (narrow end first).
