Nortec SAM-e Installation | 46
Insulation
Factory-Installed Insulation
1 Unpack tubes and headers. Inspect tubes to ensure that stainless insulation covers have not
shifted during shipping. Tube covers should not be obstructing nozzles, and should be aligned
with nozzles. Header covers should be aligned with grommets, and not obstructing tube holes.
Cut around drilled holes to create access port in side of duct. This port should be large enough
to accommodate Nortec Mini SAM-e.
2 After tubes and headers have been inspected, install tubes and header according to this chapter.
Insert all steam tubes into header such that flanges are flush with rubber gaskets. Rotate steam
tubes, as needed, to ensure all nozzles are perpendicular to airflow. Do not lift manifold by steam
tubes.
Field Retrofit of Insulation
1 Unpack insulation covers. Inspect insulating covers for shipping damage; covers should be
straight. After tubes and headers have been inspected, install tubes and headers according to
this chapter. Insert steam tubes into header, until flanges are flush with rubber gaskets. Rotate
steam tubes, as needed, to ensure all nozzles are perpendicular to airflow. Do not lift manifold by
steam tubes.
2 Install tube insulation; each tube shall receive two (2) stainless steel covers and two (2) metal
straps for every four (4) feet of tube length. Fit insulating shields around distributor tubes,
ensuring edges of shields are aligned with nozzles. Secure tubes in place with metal clamps at
top and bottom. Take care to not over-tighten. See Figure 1.
NOTE:
Multiple covers may be required to completely insulate Nortec SAM-e tube. Please
refer to Table: “Number of Insulating Covers Required to Cover a Nortec SAM-e Tube”.
