Disconnect the 5/8" 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 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. If furnace is a replacement, it is usually best to install the furnace where the old one was. Choose the location or evalu ate the existing location based upon the minimum clearance and furnace dimensions (Figure 3). FROZEN AND BURST WATER PIPE HAZARD Failure to protect against the risk of freezing could result in property damage and/or personal injury. 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.
