!WARNING

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 CSA B149.1, Natural Gas and Propane Installation Code 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. (Fig. 6)

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 Code.

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 gas-fired burning appliance to their previous conditions of use.

For Two Pipe Installation (Direct Vent)

This furnace can NOT be common vented or connected to any type B, BW or L vent or vent connector, nor to any portion of a factory-built or masonry chimney. If this furnace is replacing a previously common-vented furnace, it may be necessary to resize the existing vent and chimney to prevent oversizing problems for the other remaining appliance(s). See “Venting and Combustion Air Check” in this section. This furnace MUST be vented to the outside.

VENT AND COMBUSTION AIR

PIPING

!WARNING

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury or death.

Use methods described here to provide combustion and ventilation air.

Dual Certified

Direct or Non- Direct Vent

This furnace is certified as a Category IV furnace. This furnace can be installed as a direct vent furnace using outside air for combustion or the furnace can use air from inside the structure for combustion. The INLET air pipe is optional. If combustion air comes from inside the structure, adequate make up air MUST be provided to compensate for oxygen burned. See Confined Space Installation in the Combustion and Ventilation Air chapter. If combustion air is drawn from outside the structure, it MUST be taken from the same atmospheric pressure zone as the vent pipe.

Contaminated Combustion Air

Installations in certain areas or types of structures will increase the exposure to chemicals or halogens that may harm the furnace.

The following areas or types of structures may contain or have exposure to the substances listed below. The installation must be evaluated carefully as it may be necessary to provide outside air for combustion.

SCommercial buildings.

SBuildings with indoor pools.

SFurnaces installed in laundry rooms.

SFurnaces installed in hobby or craft rooms.

SFurnaces installed near chemical storage areas. S Permanent wave solutions for hair.

S Chlorinated waxes and cleaners.

S Chlorine based swimming pool chemicals. S Water softening chemicals.

S De-icing salts or chemicals. S Carbon tetrachloride.

S Halogen type refrigerants.

S Cleaning solvents (such as perchloroethylene). S Printing inks, paint removers, varnishes, etc. S Hydrochloric acid.

S Sulfuric Acid.

S Solvent cements and glues.

S Antistatic fabric softeners for clothes dryers. S Masonry acid washing materials.

Vent and Combustion Air Piping Guidelines

This furnace is approved for venting with Schedule 40 PVC, CPVC, ABS fittings, and Cellular Core and SDR-26 PVC pipe.

(1.) NOTE: In Canada, all pipe, fittings & cements must conform to applicable CSA standards or to local codes having jurisdiction.
