The header manifold is to be attached to a wall or other secure structure. Each valve will have
a typical distance of either 5
”
or 10
”
from center to center depending on length of tube being
used. The header assembly does not come with mounting hardware as the customer should
choose fasteners appropriate for the mounting surface.
1. The start valve (1) has two openings, one end connecting to the manifold hub and the other
end to the header tube. NOTE: Brass models will have a
½”
NPT opening and Stainless Steel
models will have a
¼”
NPT opening.
2. The start valve (1) opening will be used to connect to the inlet of the manifold hub. On the
opposite end, a 1.045-14 NGO opening will be used to attach the header tube.
3. To connect the start valve to header tube, a 1-
⅝”
wrench and 1-
⅛”
wrench will be required.
Use the 1-
⅝”
wrench to hold the valve body and the 1-
⅛”
wrench to tighten the header tube.
Torque each header tube (2) connection to 40 ft-lbs.
4. Connect mid valve (3) to the unattached end of the header tube. Ensure valve bodies are
parallel to one another. Use the 1-
⅝”
wrench to hold the valve body and the 1-
⅛”
wrench to
tighten the header tube. Torque to 40 ft- lbs.
5. Following steps 2 and 3, attach additional header tubes and mid valves as required by
application.
6. On the final mid valve (3) of the assembly, connect header plug (4) to the rear opening. Use
the 1-
⅝”
wrench to hold the valve body and the 1-
⅛”
wrench to tighten the plug. Torque to 40
ft-lbs.
7. Attach a valve bracket (6) to every valve in the assembly using the screws (8) provided.
8. Match header assembly dimensions to the mounting surface. Properly align and fasten wall
bracket to the mounting surface.
9. Mount the header assembly by connecting the valve bracket (6) and wall bracket (7) using
the provided screws and nuts. The wall bracket assembly allows for distance adjustments from
mounting surface to the header assembly.
10. Attaching the hoses: Remove either bottom or top plug (5) on the valve. Assemble pigtail to
valve block using teflon tape to seal the threads. Wrench tighten from 18 ft-lbs up to 25 ft-lbs of
torque.
