Table 1: Configuration Information
Note:
-
Baffles are always placed in the last section of radiant tube except for the 100,000 BTU Burner.
-
Baffles are either aluminized or stainless steel sections 6 ft. long.
-
When only 6 ft. is required (80,000 BTU), an aluminized steel baffle is installed.
-
When 12 ft. is required (40,000 or 60,000 BTU) the aluminized steel baffle is lengthened forward
(toward the burner)
with a 6 ft. stainless steel section.
-
In the case of a 100,000 BTU system, place 4 ft. sections of baffle in the end of each of the last 3
10 ft. sections of tube.
Part numbers for reference are:
CT026
Baffle 4 ft. long aluminized steel.
CT007
Baffle 6 ft. long aluminized steel.
CT006
Baffle extension, 6 ft. long stainless steel.
Insert (May be factory installed, CHECK FOR ORIENTAION)
To further improve heat distribution along the length of the heater, two stainless inserts may be installed
at factory, check for correct orientation. The inserts will reduce heat output in the first tube, which results
in more heat release in the latter part of the heat exchanger. (See Figure 3)
