AVERTISSEMENT:

HIGH ALTITUDE CONVERSION

(FOR NATURAL GAS INSTALLATIONS AT

ALTITUDESBETWEEN2,000&4,500FT)

When converting to high altitude with natural gas, conversion

requires replacement of the burner oriﬁces and/or adjustment

of the manifold pressure. For detailed instructions, refer to the

“High Altitude Application” section of the Installation Instructions

supplied with the furnace.

Lighting & Adjustment of the Appliance

1. Turn ON the manual gas valve, located on the outside of the

unit to the ON position.

2. Check all gas connections for leaks with a soap and water

solution. If the solution bubbles there is a gas leak which must

be corrected.

3. Turn on the electrical power to the appliance.

4. Place the gas valve ON/OFF switch/knob to the ON position.

See Figure 3.

5. Set the thermostat above room temperature to begin the

heating cycle of the furnace.

6. Check that the furnace ignites and operates properly. Refer

to the installation instructions provided with the unit for the

normal operating sequence.

7. After ignition, visually inspect the burner assembly to ensure

that the ﬂame is drawn directly into the center of the heat

exchanger tube. In a properly adjusted burner assembly, the

ﬂame color should be blue with some light yellow streaks near

the outer portions of the ﬂame.

NOTE: The ignitor may not ignite the gas until all air is bled

from the gas line. If the ignition control locks out, turn the

thermostat to its lowest setting and wait one minute then turn

the thermostat above room temperature and the ignitor will

try again to ignite the main burners. This process may have

to be repeated several times before the burners will ignite.

After the burners are lit, check all gas connections for leaks

again with the soap and water solution.

Measuring the Manifold Pressure

The manifold pressure must be measured by installing a pressure

gauge (Manometer, Magnehelic Meter, etc.) to the outlet end of

the gas valve as follows:

1. Turn off all electrical power to the appliance.

2. Shut OFF the gas supply at the manual shutoff valve located

outside of the appliance.

3. Using a 3/16” Allen wrench, remove the manifold pressure tap

plug located on the outlet side of the gas valve. See Figure

3 (page 3).

4. Install an 1/8” NPT pipe thread ﬁtting, that is compatible with

a Manometer or similar pressure gauge.

5. Connect the Manometer or pressure gauge to the manifold

pressure tap.

6. Set the room thermostat above room temperature to start the

furnace.

7. Allow the furnace to operate for 3 minutes and then check

the manifold pressure. Compare the measured value with the

value shown in Table 2 (page 3). If the manifold pressure is

not set to the appropriate pressure, then it must be adjusted.

Adjusting the Manifold Pressure

NOTE: Adjustments must be made to both LOW & HIGH ﬁre

settings when converting two-stage gas valves. Refer to Table

2 for manifold pressures.

1. Using the supplied Torx-25 Wrench, slowly turn the adjustment

screw till the appropriate manifold pressure listed in Table 2

is achieved. See Figure 2.

NOTE: Turning the screw clockwise increases the pressure,

turning the screw counter-clockwise decreases the pressure.

To prevent the screw from backing all the way out from the

valve, turn the screw slowly.

2. Replace and tighten the cap screw over the adjustment screw.

Removing the Manometer / Pressure Gauge

After the manifold pressure is properly adjusted, the Manometer

or pressure gauge must be removed from the gas valve.

1. Turn the thermostat to its lowest setting.

2. Turn OFF the main gas supply to the unit at the manual shut-

off valve, which is located outside of the unit.

3. Turn OFF all of the electrical power supplies to the unit.

4. Remove the pressure gauge adapter from the gas valve and

replace it with the 1/8” NPT manifold pressure plug that had

been removed earlier. NOTE: Make sure the plug is tight and

not cross-threaded.

5. Turn ON the electrical power to the unit.

6. Turn ON the main gas supply to the unit at the manual shut-

off valve.

COMPLETING THE CONVERSION

WARNING:

Do not alter or remove the original rating plate from

the furnace.

1. Attach the following labels:

• Theconversionwarninglabel(P/N703935)shouldbe
