FREQUENTLY ASKED QUESTIONS

Question:

What type of furnaces will this humidifier work on?

Answer: The unit will work on most forced air furnaces

incorporating a heating source, a supply duct, and a return duct

at least 8” in width.

Comment: The technology used in this humidifier to deliver

moisture to the air is the simplest and easiest style, a bypass type

evaporative humidifier. Your furnace fan creates a pressure difference

between the supply air (hot, high pressure) and return air (cold, low

pressure). By installing a bypass tube between the supply and return

duct 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. 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 several 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 for this unit is 15 US gallons per 24

hrs 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 & return duct), 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 rated output.

Question: How much moisture does the humidifier deliver to

the air in my home?

Answer: This model will deliver 15 US Gallons (12.5 Imperial

gallons, 57 litres) per 24 hours of operation.

Comment: 24 hours of operation means at design conditions; your

furnace will only deliver the required hot air (120’F) when it is on.

Your furnace should not cycle more than 1/3 of the time so the 24

hours of humidifier operation may take up to 3 days to complete.

Question: How much water does this humidifier use?

Answer: This humidifier is 100% efficient, meaning all the water it

uses is delivered to the air to humidifier your home. It will use 15

US gallons (12.5 Imperial gallons, 57 litres) per 24 hrs of operation.

Comment: As mentioned above 24 hours of operation means at

design conditions – your furnace will only deliver the required

hot air (120’F) when it is on. Your furnace should not cycle more

than 1/3 of the time so the 24 hours of humidifier operation may

take up to 3 days to complete.

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 install however some reworking may be required.

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 inlets, 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. The same goes for electrical

components or wiring these may be malfunctioning or worn out.

Note: 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 wired in with your furnace.

Do not attempt to disconnect this transformer from the furnace

only disconnect the low voltage side wires for the humidifier and

tape over the terminals.

Question: I’ve installed the humidifier on my furnace and it

is functioning properly but I do not feel anything and

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 pan and the drum assembly is getting wet then

moisture is being delivered to the air in your home.

Comment: All year, and especially during the winter months

when many combustion appliance are operating in your home,

fresh outdoor 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 homes breath (some more than

others). The cold dry outside air is mixing 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.
