Frozen Water Pipe Hazard
CAUTION
!
WATER DAMAGE TO PROPERTY HAZARD.
Failure to follow this caution may result in property
damage.
Do not leave your home unattended for long periods
during freezing weather without turning off water
supply and draining water pipes or otherwise
protecting against the risk of frozen pipes and
resultant damage.
Your furnace is designed solely to provide a safe and comfortable
living environment. The furnace is NOT designed to ensure that
water pipes will not freeze. It is equipped with several safety
devices that are designed to turn the furnace off and prevent it from
restarting in the event of various potentially unsafe conditions.
If your furnace remains off for an extended time, the pipes in your
home could freeze and burst, resulting in serious water damage.
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. Installation
WARNING
!
CARBON MONOXIDE POISONING HAZARD.
Failure to follow this warning could result in
personal injury or death.
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 Combus-
tion Air Check in Gas Vent Installation section. This
furnace MUST be vented to the outside.
Location and Clearances
1.
Refer to Figure 1 or Figure 2 for typical installation and
basic connecting parts required. Refer to Figure 5 for
typical horizontal direct vent installation and basic
connecting parts required. Supply and return air plenums
and duct are also required.
2.
If furnace is a replacement, it is usually best to install the
furnace where the old one was. Choose the location or
evaluate the existing location based upon the minimum
clearance and furnace dimensions (Figure 3).

Specifications are subject to change without notice
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.
3.
Install a reliable remote sensing device that will notify
somebody 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 11 trough Figure 20)

fitting that is located downstream of the combustion blower.
Insert a funnel into the hose and pour four(4) ounces of
sanitary type (RV) antifreeze into the condensate trap.

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.
