CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation could result in carbon monoxide poisoning or death.
The following steps shall be followed for each appliance connected to the venting system being placed into operation, while all other appliances connected to the venting system are not in operation:
1.Seal any unused openings in the venting system.
2.Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the CSA B149.1, Natural Gas and Propane Installation Codes and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
3.As far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building.
4.Close fireplace dampers.
5.Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they are operating at maximum speed. Do not operate a summer exhaust fan.
6.Follow the lighting instructions. Place the appliance being inspected into operation. Adjust the thermostat so appliance is operating continuously.
7.Test for spillage from draft hood equipped appliances at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle.
8.If improper venting is observed during any of the above tests, the venting system must be corrected in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Natural Gas and Propane Installation Codes.
9.After it has been determined that each appliance connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other
ELECTRICAL CONNECTIONS
When installed, the furnace must be electrically grounded in accordance with local codes or, in the absence of local codes, with the (U.S.) National Electrical Codes, ANSI/NFPA 70 or CSA Standard C22.1; Part 1 Canadian Electrical Code. For proper installation refer to furnace rating label for electrical ratings and for the field wiring of this unit refer to furnace wiring specifications on page 5 or alternately from the wiring diagram on page 27. In all instances, other than wiring for the thermostat, the wiring to be done and any replacement of wire shall conform with the temperature limitation for Type T wire [63°F rise (35°C)].
The electrical connections and the thermostat connections are made at the openings on either side panel of the unit in the control box area. Either side may be used as convenient, but the provided hole plugs must be inserted in the unused holes.
The control system depends on the correct polarity of the power supply. Connect "Hot" (H) wire and "Ground"
(G)wire as shown in furnace wiring specification on wiring diagram. Use reference Table on page 3 (Furnace Specifications), for over current protection, max unit amp
rating and wire size. Use copper wire only for 115V- supply service to unit. When replacing any original internal wiring, use only 105°C, 16 AWG copper wire.
Thermostat:
Instructions for wiring the thermostat are packed in the thermostat (field supplied) box. Make the thermostat connections as shown in furnace wiring specifications at the
Single Stage Thermostat Operation:
The automatic heat staging option allows a single stage thermostat to be used with a two stage furnace. To activate this option, move the jumper pin (see Figure 11) to desired setting (5 minutes or 10 minutes). The furnace will start on first (1ST) stage heat and stay at first (1ST) stage heat for the duration of the selected time before switching to 2nd stage heat.
