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. Deter- mine 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.Followthe 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. (Figure 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

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 facto- ry-built or masonry chimney. If this furnace is replacing a previous-

ly 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 out- side.

4. Vent and Combustion Air Piping

CARBON MONOXIDE POISONING HAZARD.

Failure to properly vent this furnace could result in death and/or personal injury.

Use methods described here to provide combustion

and ventilation air.

Single Pipe (N9MP1 Models)

combustion and ventilation air must comply with the gas codes or in absence of local codes, the applicable national codes.

When the installation is complete, see the" Venting and Combus- tion Air Che¢l_' in this manual.

Direct Vent (N9MP2 Models)

This furnace is certified as a category ]V appliance. This furnace uses outside air for combustion ONLY, it MUST be taken from the

same atmospheric pressure zone as the vent pipe. See Confined

Space Installation in the Combustion and Ventilation Air in this manual.

Dual Certified (*9MPD Models)

This furnace is certified as a category [V appliance. This furnace requires ventilation openings to provide air for proper combustion and ventilation of flue gases. All duct or openings for supplying

This furnace is certified as a category ]V appliance. This furnace can be installed as a direct vent furnace using outside air for com-
