WARNING
To prevent risk of fire or improper unit operation, radiant
tube baffle must be properly selected from Table 10.1
according to fuel type, burner input, and tube system length
and it must also be properly assembled and installed.
1. The last section of radiant tube is to include a turbulator baffle
assembly. Determine the quantity of baffle sections to be
installed based on the burner rating and tube system length,
per Table10.1. Discard any baffle sections that will not be
required for the assembly.
3. Insert the completed turbulator baffle assembly into the last
radiant tube, flush with the end as shown in Figure 10.2.
2. Assemble the turbulator baffle assembly by mating the
sections determined in the previous step as shown in
Figure 10.1.
Unit Mounting – Burner
1. Install four burner support brackets as shown in Figure 10.3
with the bolts supplied.
Figure 10.3 - Burner Support Bracket Installation
2. The burner must be suspended with four chains (200 lb.
minimum working load) to allow for system expansion and
contraction during unit operation, as shown in Figure 10.4.
Note that for U-tube systems mounted at a 45° angle, the
exiting side of the tube system is 12" higher than the burner
(see Figure 4.2). Locate and mount burner to ensure that
Clearance to Combustibles are maintained (refer to
"Clearance to Combustibles" on page 4).
* Max. tube length on 125MBH 2-Stage units is 50'
* Note - Tube lengths shown are for units installed at elevations of 0-2001'.
Allowable tube lengths may differ upon elevation changes.
