Frozen Water Pipe Hazard
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 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 wa-
ter lines if possible and add an antifreeze for potable water
to drain traps and toilet tanks. Open faucets in appropriate
areas.
-or-
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.
-or-
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 Fig. 10 through Fig. 19 )
1. Disconnect the >/3"(16 mm)OD rubber hose from the vent
drain 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. Reconnect the °/g” (16 mm) OD rubber hose to the
stub on the vent drain fitting. Secure with the hose clamp.
2. Disconnect the 37/4" (19 mm) OD rubber hose from the
condensate trap. Insert a funnel into the hose and and pour
four(4) (ounces of sanitary type (RV) antifreeze into the
plastic Transition box. Squeeze the hose together near the
end and quickly reconnect the 3/4," (19 mm) OD rubber
hose to the stub on 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.
INSTALLATION
4 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 Combustion Air
Check in Gas Vent Installation 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 attached 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 attached to the back of the furnace.
Location and Clearances
1. Refer to Fig. 1 for typical installation and basic connect-
ing parts required. Refer to Fig. 4 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 (Fig. 2).
FROZEN AND BURST PIPE HAZARD
Failure to follow this caution may result in property damage.
Special precautions MUST be made is 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
drain line must be protected. The use of electric heat tape or
RV antifreeze is recommended for these installations. (See
“Condensate Trap Freeze Protection Section’)
