Applying Insulation to Y-Branch and Header Fittings
LG Y-branches and Headers should be insulated with the clam-shell insulation jacket that is provided with each component. Check the fit of
the insulation jacket after all pipes are brazed to fittings. Mark all pipes at the point where the insulation jacket ends. Remove the insulation
jacket. Install field-supplied insulation on the pipe segments first, and then install the LG provided insulation plugs on the ends of all unused
Header ports. Apply the clam-shell insulation on jackets to Y-branch and Header fittings last. Peel the adhesive glue protector slip from the
insulation jacket and install the insulation jacket over the fitting.

Additional Insulation for Y-Branches and Headers May be Required in Humid Environments.
If the system has been operating for a long time in a high humidity environment (dew point temperature: more than 73°F), condensate is likely to
form. If this happens, install 3/8 inch thick ethylene propylene diene methylene (EPDM) insulation that is plenum-rated with a heat-resistance factor
of more than 248°F.
Liquid and vapor
pipe joints
Insulate the header using
the insulation attached to
the branch pipe kit as shown.
