terminal to prevent re-circulation of exhaust gases.
Figure 6.5 shows the proper location of intake and
exhaust terminals on an outside wall.
Periodic cleaning of the screens in the terminal is
required for proper operation.
Location of intake & vent terminal must comply
with all local and national codes.
VENTING
CAUTION: The humidifier shall not be connected
to a chimney flue serving any other appliances. All
venting must be installed in accordance with local and
national codes.
NOTE: These requirements apply to both
standard, direct vent units and units with outdoor
enclosure.
The GH must be vented through the top of the
cabinet.
NOTE FOR OUTDOOR ENCLOSURE: It is
recommended to vent the gas unit through the
sidewalls of the gas enclosure to eliminate possible
leakage through the enclosure root.
The vent pipe must be the same diameter as the
vent connector. See following chart for venting system
sizes and part numbers. The supplied vent
termination at the humidifier is a MALE
CONNECTION. Standard venting hook ups require a
female to male path. It is highly recommended that a
female to female adapter be assembled directly onto
the humidifier. This will establish the proper vent
sequencing. Consult with venting contractor/supplier
for proper hook up. Contact NORTEC for additional
information.
GH100 units are supplied with a 90 degree elbow
(female to female) for the vent connection. This elbow
has the correct dimensions to align the venting with
the knock-outs in the top and rear cabinet panels. The
installed venting can be connected to this elbow as
long as a proper seal can be achieved or the elbow
can be replaced with an equivalent elbow supplied by
the venting manufacturer.
The maximum flue gas temperature at the
humidifier vent connector will not exceed 480°F. Use
only special gas vents listed for use with Category III
or IV gas burning appliances, such as those listed in
the venting system chart. (Listed to UL Standard 1738
in the USA and ULC-S636 in Canada.)
