Ifthe structure will be unattended during cold weather you should take these precautions.

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-

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 Figure 8 trough Figure 17)

1.Disconnect the 5/8" OD rubber hose from the vent drain fit-

ting 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. Re- connect the 5/8" OD rubber hose to the stub on the vent drain fitting. Secure with the hose clamp.

2.Disconnect the 3/4" 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" 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.

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 chimneyto 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. RefertoFigure lorFigure 2fortypicalinstallationandba-

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 furnace where the old one was. Choose the location or

evaluate the existing location based upon the minimum

clearance and furnace dimensions (Figure 3).

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.
