Configurations
Table 1: Configuration Information
Note:
Baffles are always placed in the last section of radiant tube.
Baffles are either aluminized or stainless steel sections 6' long.
When only 6' is required an aluminized steel baffle is installed, except on the WTH-40,000 where a special 6'
stainless steel baffle with a red identification tab must be installed.
When 12' is required, a 6’ stainless steel baffle is inserted first into the end tube followed by another 6’
aluminized baffle. The stainless steel baffle is now closest to the burner.
