system can be damaged is by the failure of both
devices.
EXHAUST VENTING
- OUTDOOR UNITS
·
All required exhaust venting is provided with each
GS Outdoor model, by Nortec, including rain cap
and storm collar. All venting components
external to the unit are shipped with the unit and
must be installed on site. Refer to Figure #19 for
venting components.
·
Each vent length and the rain cap have a built-in
mechanical locking band and gasket. Simply
push together each component to the stop bead,
which provides an air & water-tight seal. Then
tighten the integrated locking band on each
component to complete the installation of the
exhaust venting.
·
The rain cap must extend at least 2 feet above
any ridge within 10 feet of the unit. The exhaust
venting can be extended using additional vent
lengths purchased from Nortec.
ELECTRICAL INSTALLATION
·
Power and control wiring is to be routed into the
humidifier through the pipe chase in the base pan
of the outdoor models located in the burner area.
·
Installation details for primary and low voltage
control wiring are the same as for indoor units.
·
A field supplied NEMA rated weatherproof
disconnect switch must be mounted external to
the GS Outdoor unit to allow for power
interruption during servicing and/or maintenance.
A mounting plate, located on the front of each
outdoor model above the electrical access door,
is available for mounting of the disconnect switch.
Two electrical conduits are provided for routing
the primary wiring to the disconnect switch and
then back inside the enclosure to the main power
terminal strip. See Figure #
20
for details.
