;_1 Connect the flexible hose as shown using clamp pro-
vided. Do not allow flexible tube to come within 3" of furnace
flue pipe because of flue pipes extreme heat. If hose is under
stress (pulling), it may be necessary to drill 2 holes in humidi-
fier collar for screws. This will prevent clamp from slipping off
(Fig. 14).

i 6 It is best to install an overflow line. Local codes may
require overflow protection. The overflow is in the bottom of
the reservoir (Fig. 15). Use 1/2" inside diameter plastic or rub-
ber tubing to connect and route to nearby floor drain. (Tubing
not furnished. Available at your local hardware store.)

WATER SUPPLY
J1 Water for the humidifier must be taken from a nearby
cold water line. Turn off the water supply. Drain by opening a
faucet at a lower level of the line.
i J2 Position the saddle valve on the water line as close
to the humidifier as possible. You have been supplied with 10
feet of 1/4" plastic tubing.
SPECIAL NOTE: When measuring the distance from the
saddle valve location to the humidifier, keep in mind that
the tubing must be supported; therefore, it must run along
ceiling and walls. Measure along the path the tubing will
follow.
3 Back out the piercing pin by turning the "T" handle
counter clockwise and then clamp the saddle valve body se-
curely on the water line with rubber gasket positioned as shown
(Fig. 16). On galvanized or copper pipe over 5/8", first drill a
5/32" hole.
CAUTION: For safety, use a hand drill or grounded
electric drill.
