TRANSPORTATION DAMAGE I WARNING All units are securely packed in shipping containers tested according to International SafeTransit Association specifications. The carton must be checked upon arrival for external damage. If damage is found, a request for inspection by carrier's agent must be made in writing immediately. WE WILL NOT BE RESPONSIBLE FOR ANY INJURY OR PROPERTY DAMAGE ARISING FROM IMPROPER SERVICE OR SERVICE PROCEDURES.
III. PRODUCT APPLICATION This furnace is primarily designed for residential home-heating applications. It is NOT designed or certified for use in mobile home, trailers or recreational vehicles. This unit is NOT designed or certified for outdoor applications. The furnace must be installed indoors (i.e., attic space, crawl space, or garage area prOVided the garage area is enclosed with an operating door).
Follow the instructions listed below when selecting a furnace location. Refer also to the guidelines provided in Section V. Combustion and Ventilation Air Requirements. o Centrally locate the furnace with respect to the proposed or existing air distribution system. o Ensure the temperature of the return air entering the furnace is between 55 F and 90 F when the furnace is heating. o Provide provisions for venting combustion products outdoors through a proper venting system.
These clearances must be permanently maintained. Clearances must also accommodate an installation's oil, electrical, and drain trap and drain line connections. If the alternate ventlflue connections are used additional clearance must be provided to accommodate these conditions Section IX, Vent Flue Pipe and Combustion Air Pipe for details. NOTE: In addition to the required clearances to combustible materials, a minimum of 24 inches service clearance must be available in front of the unit.
A return air duet system is recommended. Where there is no complete return air duct system, a return connection should be run full size to a location outside the confined space and completely sealed so that no air from the confined space can be circulated through the heating duct system. EXISTING FURNACE REMOVAL NOTE: When an existing furnace is removed from a venting system serving other appliances, the venting system may be too large to properly vent the remaining attached appliances.
PROPER VENT/FLUE AND COMBUSTION AIR PIPING PRACTICES Adhere to these instructions to ensure safe and proper furnace performance. TERMINATION LOCATIONS EXHAUST VENT/INLET AIR LOCATION The length, diameter, and number of elbows of the vent/flue pipe and combustion air pipe effects the performance of the furnace and must be carefully sized. 1. The vent piping for this furnace is approved for zero clearance to combustible construction. 2.
Sidewall Vent System g) Provide a minimum of 1 foot clearance from the bottom of the exhaust termination above the expected snow accumulation level. Snow removal may be necessary to maintain clearance. h) Provide 4 feet horizontal clearance from electrical meters, gas meters, air conditioning condensers or other external eqUipment. In no case shall the exit terminal be above or below the aforementioned equipment unless a 4 foot horizontal distance is maintained.
STANDARD FURNACE CONNECTIONS It is the responsibility of the installer to ensure that the piping connections to the furnace are secure, airtight, and adequately supported. All furnaces are shipped with a combustion air connection on the cabinet exterior and a flue connector on the inside of the cabinet on the condensate collector box.
Installations require both a vent/flue pipe and a combustion air intake pipe. Refer to the appropriate section for details concerning piping size, length, number of elbows, furnace connections, and terminations. DIRECT VENT (DUAL PIPE) PIPING BECKETT NX NON-DIRECT VENT (DUAL PIPE) INTERburner Installations require both a combustion air intake and a ventlflue pipe. The pipes may be run horizontally and exit through the side of the building or run vertically and exit through the roof of the building.
VII. ELECTRICAL CONNECTIONS I WARNING HIGH VOLTAGEI To avoid the risk of electrical shock, wiring to the unit must be polarized and grounded. ! WARNING HIGH VOLTAGEI To avoid personal Injury or death due to electrical shock, disconneCt electrical power before servicing or changing any electrical wiring. I CAUTION Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

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.

The furnace may be installed with a one-pipe system with gravity feed or lift. The maximum allowable lift on a single line system is 8 feet. Lift should be measured from the bottom (outlet) of the tank, to the inlet of the burner. Sizing a single line system is complex because of the difficulty estimating the pressure drop through each fitting, bend and component in the line. In general, keep single line systems short as possible.
INTERburner Mark 10 or Beckett NX. When the furnace is used in connection with a cooling unit, the furnace should be installed in parallel with or on the upstream side of the cooling unit to avoid condensation in the heating element.
Drill a 3/8" hole in the PVC exhaust vent piping approximately 18" above where the PVC exits the side of the furnace for your combustion analysis equipment. (Seal with RTV silicone when finished conducting combustion analysis). 1. Operate furnace with burner firing for approXimately ten minutes. Ensure all registers are open and all duct dampers are in their final (fully or partially open) position. 2. Place thermometers in the return and supply ducts as close to the furnace as possible.
Circulator Blower Speeds Low Red Medium Blue Hiah Common/Neutral Black White XII. NORMAL SEQUENCE OF OPERATION POWER UP MODE The normal power up sequence is as follows: • • 115 VAC power applied to furnace Furnace awaits call from thermostat HEATING MODE The normal operational sequence in heating mode is as follows: Rand W thermostat contacts close, • initiating a call for heat Closure of the thermostat switch through relay #1 energizes primary control on the burner.
Table 1 System and General Troubleshooting PROBLEM Furnace will not start Furnace will not start without first pushing oil primary control reset button. Thermostat not calling for heat. Check thermostat and adjust. Be sure it is accurate. If it is mercury type be sure it Is level. No I)OWer to furnace. Check furnace switch and main electrical Dane! furnace fuse or circuit breaker. Thermostat faulty. Remove thermostat wires from the oil primary control terminal T·T. Put a jumper across T-T.
Table 1 PROBLEM Oilbumer sputtering at nozzle System and General Troubleshooting REMEDY POSSIBLE CAUSE Electrodes out of adjustment or defective. Check etectrode settings. Check electrodes for dirt build-up or cracks in porcelain. Poor transformer high voltage connections or defective transformer. Check contacts between the igniter and electrodes. If OK, replace the Igniter. Fuel oil filter cloaaed. Replace fuel oil storage tank filter and/or fuel oil in-line filter. Defective 011 pump.
Table 1 PROBLEM System and General Troubleshooting REMEDY POSSIBLE CAUSE Home does not heat evenly. Improper distribution of heat. This Is unlikely to be a furnace problem. Balance duct system with dampers. Supply air temperature too hot. Airtlow blocked or dirty air filter. Clean or replace air filter. Insufficient airflow. Check all dampers. Open closed dampers including registers in unused rooms. Check system temoerature rise. If temcerature rise Is too hiah &Deed UD blower fan.
