Frozen Water Pipe Hazard
CAUTION
!
WATER DAMAGE TO PROPERTY HAZARD
FaiIure to protect against the risk of freezing 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 de-
vices 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.

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to properly vent this furnace or other
appliances could result in death or personal injury.
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 the 5. Combusion & Ventilation Air
section. This furnace MUST be vented to the
outside.

Installation Positions

This furnace can be installed in an upflow, horizontal (either left or
right) or downflow airflow position. DO NOT install this furnace on
its back. For the upflow position, the return air ductwork can be at-
tached to either the left or right side panel and/or the bottom. For
horizontal and downflow positions, the return air ductwork must be
attached to the bottom. The return air ductwork must never be at-
tached to the back of the furnace.

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 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 9 trough Figure 18)

1. Disconnect the / ² OD rubber hose from the vent drain fit-
8
ting that is located downstream of the combustion blower.
Insert a funnel into the hose and pour four(4) ounces of sani-
tary type (RV) antifreeze into the condensate trap. Recon-
5
nect the / ² OD rubber hose to the stub on the vent drain
8
fitting. Secure with the hose clamp.

2. Disconnect the / ² OD rubber hose from the condensate
4
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
3
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.

Location and Clearances

1. Refer to Figure 1 or Figure 2 for typical installation and
basic connecting parts required. Refer to Figure 3 for typi-
cal 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 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 4).
CAUTION
!
FROZEN AND BURST WATER PIPE HAZARD
FaiIure to protect against the risk of freezing may
result in property damage.
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.
