FREQUENTLY ASKED QUESTIONS

QUESTION: Why use a flow-through style humidifier rather than a drum style humidifier?
ANSWER: This will depend on several factors including size of home, type of furnace, and size
of ducting; as well as personal preference. However in order to use this model flow through you
will require at least 10" wide ducting where as our drum styles will fit on 8" wide ducting.
COMMENT: Flow-through and rotating-drum style evaporative furnace humidifiers will safely
and efficiently humidify 90% of homes which use forced air heating. As a manufacturer of both
styles there are pro's and con's to be considered when choosing a flow through or drum style.
A drum-style humidifier will typically have a higher output when compared to a flow through
of equal size, however with today's modern home construction and insulation techniques
the higher capacities are not required, over humidification is something that should be well
guarded against. Another point to consider is the fact that a drum style humidifier is 100%
efficient (meaning that all the water supplied to the unit is delivered to the air) where as the
flow through styles range anywhere from 30% to 40% efficient (meaning that for every gallon
of water delivered to the air 2 gallons will be allowed to flow through). Today, indoor air quality
(IAQ) is an issue on everybody's mind and the inefficiency of flow through humidifiers is by
design as the water flowing through serves to flush away any unwanted minerals and such
leaving only clean water to be evaporated. The cost of maintaining (typically a evaporator
pad once a year) and operating a flow through style is far less when compared to the cost of
maintaining a drum style humidifier to ensure healthy and efficient operation.
QUESTION: What type of furnaces will this humidifier work on?
ANSWER: The unit will work on most forced air furnaces which incorporates a heating source,
a supply duct, and a return duct.
COMMENT: The technology used in this humidifier to deliver water to the air is not new, it is the
simplest and easiest style a bypass type evaporative humidifier. Your furnace fan creates a pressure
difference between the supply (hot) air and the return (cold) air. By installing a bypass tube between
the supply and return air a small amount of air is forced (via the pressure difference) to flow from
the supply duct through the humidifier's evaporator pad and back into the return duct where it will
mix with all the return air from your home. As the hot air passes through the evaporator pad it will
"evaporator" moisture and deliver it to your home. What will differ from furnace to furnace or home
to home is how much moisture or capacity you will get from the unit. There are many factors which
will affect this: How old is your home? How old is your furnace? How well insulated is your home?
For example, the capacity of the unit is 12 US gallons per 24 hours of operation. This is based
on ARI standards (120°F hot air temp, 60°F water supply temp, 0.5" static pressure difference
between supply and return) used by all humidifier manufacturers. If your furnace is a hi efficiency
or pulse type furnace the hot air temperature may be less or the length of time the furnace burner
is on may be less; therefore as a rule of thumb we would say you would get approx 75% to 80% of
the rated output. Generally speaking high-efficient furnaces are used in homes which are very well
insulated and therefore the 75% or 80% capacity will be more than enough to humidify the home.
QUESTION: How much moisture does the humidifier deliver to the air in my home?
ANSWER: This model will deliver 12 US Gallons (10 Imp. Gallons, 45.5 Litres) per 24 hrs of operation.
COMMENT: 24 Hrs of operation means continues humidifier operation. This unit delivers
sufficient moisture to humidify the average home up to 3200 sq ft. The humidifier will ensure
that when your furnace is heating it is delivering humidified air to your home.
QUESTION: How much water does this humidifier use?
ANSWER: This humidifier incorporates a restrictor which meters the amount of water supplied
to the unit. In a average home the unit will use 37 US Gallons (31 Imp. Gallons, 140 Litres) per
24 hrs of operation.
COMMENT: Your furnace will not run continuously 24 hrs a day; in an average home the 36
gallons will be used over a 3 day period.
QUESTION: I'm replacing an old humidifier on my furnace can I use the old components?
ANSWER: You should replace all the components to ensure good operation. You may be able to
utilize the existing duct cut outs for the new installation (see section in the instructions.)
COMMENT: As a rule we like to see you change all the components, particularly the water
supply tube, as over time minerals, solids, or sludge may have built up, these will very quickly
clog the water inlet of the flow through, or over time the tube may have become worn or
leaky. Replace the bypass duct as well there may be secondary dampers unseen which will
block air or again there may be unseen wear which will cause air leaks. Same with electrical
components or wiring these may be malfunctioning or worn out. If you have a humidifier which
was interlocked with your furnace (meaning the humidifier only came on when the furnace
came on) then the old transformer is getting power from the internal furnace wiring. You should
leave this transformer and wiring in place; if this transformer is functioning and it is 24 Volts
AC, you may be able to utilize it to control the new humidifier.
QUESTION: I've installed the humidifier on my furnace and it is functioning properly but I do not
feel anything and the humidistat reading is not changing, is the humidifier working?
ANSWER: As long as there is hot air going through the humidifier and there is water getting to
the evaporator pad moisture is being delivered to the air in your home.
COMMENT: All year, and especially during the winter months when many combustion
appliances are operating in your home, fresh air is required to ensure a healthy environment
for your family. Do not think of your home as a sealed bubble, no matter how well insulated.
All houses breath (some more than others) the cold outside air mixes with the air in your home
constantly, even when your furnace is not running. A furnace humidifier will work to offset the
constant effect the dry outside air has on your home, and your home's furnishings. Throughout
the winter there is a constant diminishing and replenishing of moisture levels in the home,
conditions inside and out rarely remain stagnant for any length of time.

INSTALLATION AND OPERATING INSTRUCTIONS:
MODEL 6000 FLOW THROUGH HUMIDIFIER
• READ THESE INSTRUCTIONS FULLY BEFORE INSTALLING THIS HUMIDIFIER.
• SAVE THESE INSTRUCTIONS FOR REFERENCE.
• DO NOT INSTALL THIS HUMIDIFIER ON A DUAL FUEL WOOD OR ANY OTHER SOLID FUEL
BURNING FURNACE.
• DUE TO UNIQUE FURNACE SETUP OR OPERATION THE PURCHASE OF A SEPARATE
COMPONENT (LENGTH OF THERMOSTAT WIRE, PRESSURE SWITCH OR HARDWIRE TX KIT)
MAYBE NECESSARY.
• THIS HUMIDIFIER REQUIRES A FORCED AIR HEATING SYSTEM WITH A SUPPLY AND RETURN

• MINIMUM 10" WIDE DUCTING REQUIRED TO MOUNT THE HUMIDIFIEIR.
• LEAVE AT LEAST 12" OF CLEARANCE FROM THE FURNACE BODY WHEN MOUNTING ANY
COMPONENTS.
• WHEN DRILLING OR CUTTING INTO DUCTING BE EXTREMELY CAREFUL NOT TO DAMAGE

REQUIRED TOOLS

• Safety glasses
• Work gloves
• Electric drill
• Drill bits (3/8", 1/8", 5/64")
• Tin snips
• Measuring tape or ruler
• Medium-grit sand paper
• Full size Philips or Roberstons screw driver
SELECTION OF LOCATION TO MOUNT THE HUMIDIFIER
All bypass type furnace humidifiers rely on the pressure difference which exists between the
supply duct (hot air) and the return duct (cold air) to create an air-flow through the humidifier's
evaporator pad. The air will ALWAYS flow from HOT (high pressure) to COLD (low pressure).
Selecting the proper location, and installing the humidifier properly as intended by the
manufacturer is imperative for the proper operation of the humidifier – see illustrations below
along with the brief explanations as to what is a good installation and what is not.
INSTALLATION TIP: Before starting fully plan out the installation. Check for the locations of the
humidifier, bypass collar and damper, the length and type of ducting required, the water supply,
the water drain, the electrical wiring, and a constant 120 volt outlet to plug in the transformer.
This will ensure your installation goes as easy and quickly as possible.
