Indoor Humidity; Propane Furnaces Only - Amana GUC* User's Informational Manual

WARNING
To prevent possible death or personal injury
due to asphyxiation, common venting with
other induced draft appliances is not al-
lowed. Carefully read and follow all instruc-
tions given in this section.
NOTE: The louvers in the furnace door and top must never
be obstructed. They must remain open so air can flow
through the furnace and cool internal components.

Indoor Humidity

Relative humidity is the amount of water vapor in the air
relative to the amount the air can hold at the same tempera-
ture. Example: At 40% relative humidity, the air could hold 2
1/2 times as much moisture (2.5 x 40 = 100%) before
becoming saturated.
The colder the air; the less moisture it can hold. As air is
warmed, its ability to hold moisture is increased.
Example: A winter day, outdoor temperature 10°F, and
relative humidity of 70%. If that air enters a home and is
warmed to 72°F. the relative humidity will drop to 6% (very
dry) if no more moisture is added.
Relative humidity is important to your health and home as
proper humidification helps reduce respiratory difficulties
and helps improve the indoor air quality.
A good relative humidity is one just high enough to barely
start condensation along the lower edges or lower corners of
the windows. More than that can be damaging.
Frequent fogging or excessive condensation on inside win-
dows indicates the indoor humidity level is too high for
outdoor weather conditions. Damage to the building may
result if the condition persists. (Condensation on inside of
storm windows indicates loose inside windows. Adding
weather-stripping to tighten inside windows usually corrects
this problem.)
The following table shows the recommended maximum
indoor humidity in relationship to the outdoor temperatures.

Propane Furnaces Only

WARNING
PERSONAL INJURY HAZARD
To avoid death, personal injury or property
damage due to explosion or fire, install a gas
detecting warning device. Since the odorant
in propane gas can be reduced by iron oxide
(rust), a gas detecting warning device is the
only reliable method to detect propane gas
leaks.
WARNING
PERSONAL INJURY HAZARD
If the gas furnace is installed in a basement,
an excavated area or a confined space, it is
strongly recommended to contact a propane
supplier to install a gas detecting warning
device in case of a gas leak.
• Since propane gas is heavier than air, any
leaking gas can settle in any low areas or
confined spaces.
• Propane gas odorant may fade, making
the gas undetectable except with a warn-
ing device.
An undetected gas leak will create a danger
of explosion or fire. If the presence of gas is
suspected, follow the instructions on the
cover of this manual. Failure to do so could
result in SERIOUS PERSONAL INJURY OR
DEATH.
