Power supply to the furnace must be N.E.C. Class 1, and must comply with all applicable codes. and/or The Canadian Electric Code CSAC22.1. Use a separate fused branch electrical circuit containing properly sized wire, minimum 12 gauge, and fuse or circuit breaker. The furnace must be electrically grounded in accordance with local codes or, in their absence, with the latest edition of: The National Electric Code, ANSI NFPA 70. The fuse or circuit breaker must be sized in accordance with the maximum over-current protection specified on the unit rating plate. An electrical disconnect must be provided at the furnace location. NOTE: Line polarity must be observed when making field connections. I WARNING THE DRAIN TRAP MUST VBE MOUNTED ON THE OPPOSITE SIDE OF THE UNIT FROM THE JUNCTION BOX. THIS WILL REDUCE THE RISK OF WATER REACHING THE JUNCTION BOX IN THE EVENT OF A BLOCKED DRAIN CONDITION. Connect hot, neutral, and ground wires as shown in the wiring diagram located on the unit's blower door. Line polarity must be observed when making field connections. Line voltage connections can be made through either the right or left side panel. The furnace is shipped configured for a right side electrical connection with the junction box located inside the blower compartment. To make electrical connections through the opposite side of the furnace, the junction box must be relocated to the other side of the blower compartment prior to making electrical connections. NOTE: Wire routing must not interfere with circulator blower operation, filter removal, or routine maintenance. I WARNING EDGES OF SHEET METAL HOLES MAY BE SHARP. USE GLOVES AS A PRECAUTION WHEN REMOVING HOLE PLUGS. 12 HITHERMOSTAT AIR Y ~ CAD=f ~y? : t~ &~;-------~~~ C .

To ensure proper unit grounding, the ground wire should run from the furnace ground screw located inside the furnace junction box all the way back to the electrical panel. NOTE: Do not use oil piping as an electrical ground. To confirm proper unit grounding, turn off the electrical power and perform the following check: 1. Measure resistance between the neutral (White) connection and a suitable chassis ground. 2. Resistance should measure 10 ohms or less. This furnace is equipped with a blower door interlock switch which interrupts unit voltage when the blower door is opened for servicing. Do not defeat this switch. 24 Volt Thermostat Wiring NOTE: Wire routing must not interfere with circulator blower operation, filter removal, or routine maintenance. Low voltage connections can be made through either the right or left side panel. Thermostat wiring entrance holes are located adjacent to the junction box locations in the blower compartment. Thermostat Diagram This furnace is equipped with a 40 VA transformer to facilitate use with most cooling equipment. Consult the wiring diagram, located on the blower compartment door, for further details, of 115 Volt and 24 Volt wiring. VIII. CONDENSATE DRAIN LINES & DRAIN TRAP GENERAL A condensing oil-fired furnace achieves its high level of efficiency by extracting almost all of the heat from the products of . combustion and cooling them to the point where condensation takes place. The condensate which is generated must be piped to an appropriate drain location. The furnace's drain hoses may exit either the right or left side of the furnace. In horizontal installations, the drain hoses will exit through the bottom (down side) of the unit with the drain trap suspended beneath the furnace. The field-supplied drain system must be in accordance with all local codes and the instructions in the following sections. Follow the instructions below when installing the drain system. Refer to the following sections for specific details concerning furnace drain trap installation and drain hose hook ups. The drain trap supplied with the furnace must be used. DRAIN TRAP ASSEMBLY Check for proper fit of the entire assembly Before cementing the individual components together. Place the flexible pipe coupling on the sub protruding from the 90 degree elbow connected to the condensate collector, then insert the 6 inch pipe stub and tighten the clamps on each end of the flexible coupling. Attach the tee to the stub coming out of the furnace and insert 10 inch stub to bottom of the tee. Attach the trap asse...
