COMBUSTION TUBE INSTALLATION
The first section or radiant tube downstream of the burner
is a heavy wall 16 Ga. aluminized steel tube. This tube is
referred to as the combustion tube. One end of this tube
is swaged to fit inside the next spiral radiant tube. The
end that is un-swaged is coupled to the burner assembly –
see page 19. It is necessary that the weld seam on this
combustion tube be positioned so that it is on the bottom
when installed.
This applies for both straight tube and “U” tube systems.
When the systems are mounted on a 30° angle the weld
seam should always be on the bottom.

DAMPER TYPES
Damper assemblies are to be installed as per layout
drawing. Each burner flow must be equipped with a
damper assembly so that accurate vacuum settings can
be made.
NOTE:
Install damper handles on the side or bottom,
position locating holes so that they face, or rotate
downward. The damper handle can be rotated by
removing the two nuts, which hold the blade, and setting
plate in place. Rotate 180° and reassemble - take care so
as not to "strip out" handle. When turning the damper
handle, the center-retaining spud on the opposite side
should rotate simultaneously.
