WeatherMaker 8000™ 58ZAV Downflow/Horizontal Induced-Combustion Furnaces Installation, Start-Up, and Operating Instructions Sizes 050—135, Series 140 NOTE: Read the entire instruction manual before starting the installation. This symbol → indicates a change since the last issue.
ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS PROCEDURE Electrostatic discharge can affect electronic components. Take precautions during furnace installation and servicing to protect the furnace electronic control. Precautions will pre- vent electrostatic discharges from personnel and hand tools which are held during the procedure.
INTRODUCTION The model 58ZAV Series 140 Furnaces are available in sizes 46,000 through 135,000 Btuh input capacities. The design of the downflow/horizontal gas-fired furnace is A.G.A./C.G.A. certified for natural and propane gases and for installation on noncombustible flooring.
Improper installation, adjustment, alteration, service, mainte- nance, or use can cause carbon monoxide poisoning, explo- sion, fire, electrical shock, or other conditions which may cause personal injury, loss of life, or property damage.
The operation of exhaust fans, kitchen ventilation fans, clothes dryers, or fireplaces could create a NEGATIVE PRESSURE CONDITION at the furnace. Make-up air MUST be provided for the ventilation devices, in addition to that required by the furnace. All fuel-burning equipment must be supplied with air for combus- tion of the fuel.
Step 3—Supply Air Connections DOWNFLOW FURNACES Connect supply-air duct to supply-air opening on furnace. The supply-air duct attachment must ONLY be connected to furnace supply/outlet or air conditioning coil casing (when used), when installed on non-combustible material.
to attach any portion of return-air duct. Bypass humidifier connec- tions should be made at ductwork or coil casing sides exterior to furnace. Step 5—Downflow Installation NOTE: This furnace is approved for use on combustible materials or wood flooring.

INSTALL FURNACE 1. Position furnace in desired location. 2. Connect gas supply pipe. See Fig. 8 for typical piping entry. 3. Install field-supplied filter retainers as indicated in Fig. 11 and Table 4 before connecting return-air duct to furnace. 4. Connect supply- and return-air ducts.
Use the proper length of pipes to avoid stress on the gas control manifold. Failure to follow this warning could result in a gas leak, causing fire, explosion, personal injury, or death. Connect the gas pipe to the furnace using a backup wrench to avoid damaging gas controls.
Canadian installations, all electrical connections must be made in accordance with Canadian Electrical Code CSA C22.1, or authori- ties having jurisdiction. NOTE: Proper polarity must be maintained for 115-v wiring. If polarity is incorrect, control status code indicator light will flash rapidly and furnace will not operate.

Step 12—Start-up, Adjustment, and Safety Check GENERAL NOTE: Proper polarity must be maintained for 115-v wiring. If polarity is incorrect, control status indicator light will flash rapidly and furnace will not operate. The furnace must have a 115-v power supply properly connected and grounded.

NOTE: If orifice hole appears damaged or it is suspected to have been redrilled, check orifice hole with a numbered drill bit of correct size. Never redrill an orifice. A burr-free and squarely aligned orifice hole is essential for proper flame characteristics.
EXAMPLE: (0—2000 ft altitude) Btu heating input = Btu/cu ft X cu ft/hr Heating value of gas = 1050 Btu/cu ft Time for 1 revolution of 2-cu ft dial = 82 sec Gas rate = 88 cu ft/hr (from Table 9) Btu .
Recheck temperature rise. It must be within limits specified on unit rating plate. Recommended operation is at midpoint of rise or above. 3. Set thermostat heat anticipator. The thermostat heat anticipation must be set to match the amp draw of the electrical components in the R-W circuit.
