Baffle Assembly and Placement

Baffle Assembly and Placement
Different models and inputs utilize specific baffle lengths. Remove all enclosed baffle sections from box
and retain with applicable heater. Reference shipping label for proper baffle size.
To assemble the baffles: NOTE: Baffles may be inserted into the tube while being assembled.
Determine the number of baffles needed for your model number. Remove one 36 in. baffle section
1
if heater is fitted with an elbow (P/N: E6) or U-bend (P/N: TF1B) accessory.
Orient the baffle tabs at a 90° angle to the baffle keyhole (see figure 3.19).
2
Insert one baffle tab into keyhole and slide completely to one side until both baffle tabs appear in
3
the keyhole.
Adjust the tabs to the center of the keyhole and rotate the baffle 90 degrees to lock the baffle
4
sections together.
Repeat this process with all remaining baffle sections to complete assembly.

Rotate baffle assembly so that it is in the vertical position.

NOTE: Baffle assemblies longer than 10 ft. will continue to be fed into next tube section. When the
heater is configured with a 'U' or 'L' shaped accessory fitting It may be necessary to cut the
baffle in two sections. In this case, place as much baffle as possible downstream of the fitting and the
remainder just before the fitting.
