I WARNING

HIGH VOLTAGEI

TO AVOID THE RISK OF INJURY, ELECTRICAL SHOCK OR DEATH, THE FURNACE MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES OR IN THEIR ABSENCE, WITH THE LATEST EDITION OF THE NATIONAL ELECTRIC CODE.

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

Acondensing 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 assembly to the bottom of the stub using PVC pipe coupling. Do Not use pipe cement on the flexible pipe coupling. Add water to the trap until some runs out of the drain overflow. Do not install the drain in areas SUbject to freezing.

DRAIN CONNECTION

Insert the ~ inch 10 tUbing through the hole in the cabinet and press on to the barb fitting. Do not use excessive force

on the drain pan. Connect the other end to the top 90 degree barb on the drain trap assembly. Connect another piece of tubing to the bottom of the tee on the drain trap and run to the condensate neutralizer. The condensate neutralizer must lay in a horizontal position. Connect installer furnished tUbing (type UVT or equivalent, ~" 10) to the other end of the condensate neutralizer and run to a drain. Do not install the drain in areas subject to freezing.
