To install the radiant tubes:
Place tubes in hangers with the welded seam facing downward and the swaged end of the tube
1
towards the exhaust end of the heater system (see figure 3.6).
Refer to page 23 for tube installation sequence. Place the combustion chamber as the first tube
connected to the burner control box. Models 150-200 MBH utilize a titanium combustion chamber with
yellow identification tag.

the radiant tube surface.
IMPORTANT! 150,000 to 200,000 BTU/h models must be installed
with a stainless steel tube clamp (P/N: TP-220) located at the seam
between the primary combustion chamber and the second tube
section downstream of the burner control box.
