INSTALLATION

Important:

• Remove all shipping brackets and materials before

operating the humidifier.

• Humidifier flue gases must be vented to the outside

atmosphere.

• Power supply disconnect switch must be in the off

position while making wiring connections to prevent

electrical shock and equipment damage. All units must

be wired in strict accordance with wiring diagram furnished

with this unit.

• Turn off all gas while installing the run-out and manual

shut-off valve for the humidifier.

Locating the Humidifier

• Provide a level, solid foundation for the humidifier.

Locate the humidifier as near as possible to chimney or

outside wall so that the flue pipe from the humidifier is

short and direct. The location should also be such that

the gas ignition system components are protected from

water during humidifier operation and service.

• The humidifier should be installed in a location away

from drafts and properly protected. If installed in a

separate room, follow the instructions concerning

combustion and ventilation air.

• The humidifier should be located in an area where

leakage from the tank or its connections will not result

in damage to the adjacent structure or to lower floors of

the structure. When such locations cannot be avoided,

it is recommended that a suitable drain pan, adequately

drained, be installed under the humidifier. The pan must

not restrict combustion air flow.

• The humidifier must not be installed on carpeting, tile,

or other combustible material other than wood flooring

(indoor application only).

• Install humidifier so electrical components are pro-

tected from water.

• The appliance must be kept free and clear of insulat-

ing materials when located in an insulated space.

Insulating material may be combustible. Inspection of

the appliance area must be performed when the appli-

ance is installed, or when insulation is added.

Supply Water and Drain Overflow

Connections

IMPORTANT: The humidifier is shipped with the auto-

matic drain valve locked in the manual open position.

This position reduces the possibility of damaging the

valve seat from the heat of sweating the drain connection

during installation. After the drain connection has been

completed the "manual open" lever position must be reset

to the auto position. Failure to close the drain valve will

not allow the tank to fill.

Regardless of the type of water used, the following

general instructions must be followed:

• Union connections must be made at the humidifier on

the cold water supply and drain/overflow lines.

• A shut-off valve should be provided in the supply water

line to isolate the humidifier from the water system while

servicing.

• If the water pressure is above 60 psi and/or water

hammer would be objectionable, a pressure reducing

valve or shock arrester should be installed.

• A 3/4” opening is provided in the humidifier tank to

accommodate skim and/or overflow protection. A water

seal is required on the drain/overflow connection and a 1”

air gap should be provided prior to a building drain. (Note:

Follow local code requirements regarding size of drain

pipe.) The water seal must be piped to hold steam in the

humidifier and also provide a pressure relief if the steam

outlet becomes clogged. (See diagram on page 15)

• Insulating unions or bushings must be used to make

connections between copper and other dissimilar metal

fittings, such as galvanized steel. These insulating

fittings are required to minimize electrolytic corrosion,

which results from the direct connection of dissimilar

metals in a water system.

• Before beginning ignition sequence of the humidifier at a

new installation, be sure the humidifier tank is full of water

and the water is free to flow into the tank.
