If your furnace remains off for an extended time, the pipes in your
home could freeze and burst, resulting in serious water damage.
Water may create a condition in which mold can grow in your home.
Certain types of mold have been reported to cause respiratory
problems or other serious health risks. Remedial actions, including
immediately drying all wet items, should be taken quickly to help
prevent the development of mold in your home.
If the structure will be unattended during cold weather you should
take these precautions.
1.
Turn off the water supply to the structure and drain the water
lines if possible and add an antifreeze for potable water to
drain traps and toilet tanks. Open faucets in appropriate
areas.
2.
Have someone check the structure frequently during cold
weather to make sure it is warm enough to prevent pipes
from freezing. Instruct them on a service agency to call to
provide service, if required.

CARBON MONOXIDE POISONING HAZARD
Failure to properly vent this furnace or other appliances
can result in death, personal injury and/or property
damage.
This furnace can NOT be common vented or connected to
any type B, BW or L vent or vent connector, nor to any
portion of a factory- -built or masonry chimney. If this
furnace is replacing a previously common-vented
furnace, it may be necessary to resize the existing vent
and chimney to prevent oversizing problems for the other
remaining appliance(s). See Venting and Combustion Air
Check in Gas Vent Installation section. This furnace MUST
be vented to the outside.
Location and Clearances
4.
Refer to Figure 1 or Figure 2 for typical installation and ba-
sic connecting parts required. Refer to Figure 4 for typical
horizontal direct vent installation and basic connecting parts
required. Supply and return air plenums and duct are also
required.
5.
If furnace is a replacement, it is usually best to install the fur-
nace where the old one was. Choose the location or evalu-
ate the existing location based upon the minimum clearance
and furnace dimensions (Figure 3).

Install a reliable remote sensing device that will notify some-
body of freezing conditions within the home.
Winter Shutdown
If you go away during the winter months and do not leave the heat
on in your home, the plastic transition box and the condensate trap
on the furnace must be protected from freeze damage.(See
Figure 8 trough Figure 17)

trap. Insert a funnel into the hose and and pour four(4)
ounces of sanitary type (RV) antifreeze into the plastic Tran-
sition box. Squeeze the hose together near the end and
quickly reconnect the
condensate trap. Secure with the hose clamp.
When you return home, your furnace will be ready to start, as it is
not necessary to drain the antifreeze from the furnace.
CAUTION
Special precautions MUST be made if installing furnace in an
area which may drop below freezing. This can cause improper
operation or damage to equipment. If furnace environment
has the potential of freezing, the drain trap and drainline must
be protected. The use of electric heat tape or RV antifreeze is
recommended for these installations. (See "Condensate Trap
Freeze Protection Section")
Do NOT operate furnace in a corrosive atmosphere
containing chlorine, fluorine or any other damaging
chemicals. Refer to Combustion & Ventilation Air section,
Contaminated Combustion Air.
