Page 5: Furnace Location
FURNACE LOCATION IMPORTANT Please read this entire manual and all labels before installing the furnace. UNPACKING AND INSPECTION It is the responsibility of the consignee of the unit to examine the packages for damage and, if found, to note the same on the Carrier’s Bill of Lading. The NH3 furnace is shipped in one package complete with oil burner, draft regulator, filter racks, air filters, A/C Control Center (optional) and instruction manual. - Page 6 The WMO-1 blocked vent control is required on Newmac oil-fired and combination furnaces or boilers installed in Canada. The WMO-1 switch must be installed on the chimney vent pipe for Newmac oil fired furnaces and boilers; and installed on the burner plate for Newmac combination wood/oil or coal/oil fired furnaces.

PROPER DUCT SIZING Locate the furnace as close as possible to the center of the heat distribution system and make sure the top is level. Refer to TABLES 6 and 7, DUCT SIZING FOR HEATING and COOLING in this manual. AIR CONDITIONING This appliance is designed to accommodate air conditioning equipment. - Page 8 FAN & LIMIT CONTROL This thermally operated control has a probe to sense air temperature inside the appliance adjacent to the heat exchanger. Fig. 3 shows the main parts of a Honeywell L4064 Fan & Limit Control. Refer to Fig. 4 for its settings.
- Page 9 However, every house is subject to different internal and external conditions and regulations vary among localities. With this in mind, Newmac recommends provision for combustion and ventilation air as specified in Table 5. Table 5 is based on relevant commonly available codes and regulations.
- Page 10 The incoming cold air is confined to the furnace room. Therefore, the residence occupants are less susceptible to drafts. Cool outdoor air will be tempered by the ambient temperature of the furnace room before it enters habitable spaces. Noise levels may be reduced.
- Page 11 OIL BURNER INSTRUCTIONS BURNER CARE This burner is fully automatic in operation. All adjustments should be made by a qualified technician. Keep the burner free from excess dirt and moisture. Oil leaks should be tended to immediately. If the burner motor has oiler openings, the motor should be given a few drops of SAE 20 non-detergent oil at least two or three times a year.

- Page 13 Install the pressure gauge directly on the gauge or nozzle port. Adjust to the pressure specified by Newmac for the nozzle input rating. Refer to TABLE 1 (NH3) or 3 (LFR), GENERAL INSTRUCTIONS in this manual or the certification label on the appliance.
- Page 14 See FIG. 15 for STANDARD WIRING SCHEMATIC - BELT DRIVE and follow the motor manufacturer’s instructions. Make sure replacement and retrofit belt drive motors meet or exceed the OEM motor specifications. Two speed belt drive motors are available from Newmac.
- Page 15 The heat exchanger should be inspected on an annual basis. If cleaning is required, remove the cleanout cover. Use a wire brush or cleaning tool (available from Newmac) to loosen scale and soot and a vacuum cleaner to remove it from the furnace. Replace gaskets if necessary before replacing the cleanout cover.
- Page 16 IMPORTANT HOMEOWNER INSTRUCTIONS 1. AN EMERGENCY POWER SWITCH IS REQUIRED TO BE INSTALLED IN A CONVENIENT LOCATION AT A SAFE DISTANCE FROM THE BURNER. THIS SWITCH INTERRUPTS THE ELECTRICAL SUPPLY CIRCUIT TO THE APPLIANCE. MAKE SURE YOU ARE AWARE OF ITS LOCATION AND THE OFF POSITION IS CLEARLY MARKED.
