5.3 Insulation
The heat exchanger and top ange section of the YARS MUST always be insulated by at least two inches (obtained from
a local supplier). This will reduce the inuences of ambient air temperature uctuations and cause the heat exchanger to
operate more eciently. Insulation should be installed at site after installation and leak testing and should be congured for
possible future maintenance and access.
It is generally required to have the lter section insulated only when ambient temperatures fall below 32
o
F (0
o
C). Insulation
should conform to appropriate site standards. This insulation may not be required during hot summer months however
only on-site experience can determine the exact insulation requirements for the lter section.
