FOR R8HE / PPG3HE SERIES, CONDENSING STYLE, GAS / ELECTRIC PACKAGE UNITS
BEFORE THE CONVERSION
IMPORTANT: Please read all instructions before
converting the unit. Pay attention to all safety warnings
and any other special notes highlighted in the manual.
Safety markings are used frequently throughout this
manual to designate a degree or level of seriousness and
should not be ignored. WARNING indicates a potentially
hazardous situation that if not avoided, could result in
personal injury or death. CAUTION indicates a potentially
hazardous situation that if not avoided, may result in minor
or moderate injury or property damage
This conversion kit is only to be used to convert natural

CONVERTING TO LP/PROPANE GAS AT
ALTITUDES BETWEEN ZERO & 4,500 FT.
Converting the two-stage gas valve to LP/Propane requires
the replacement of the burner orifices and/or the stem/spring
assembly in the pressure regulator.
Table 2 (page 4), provides the manifold pressure for altitudes
above 2,000 feet.

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 to the ON position.
See Figure 2.
5. Set the thermostat above room temperature to begin the
heating cycle of the furnace.
IMPORTANTNOTE:Beforeinstallinganorice,check
thesideorfaceoftheoriceforthedrillnumberand
verifythatitistheappropriatesize.
12. Install the appropriate LP/Propane gas burner orifices
into the gas manifold assembly.
NOTE: To prevent cross threading, hand tighten the orifices
into the gas manifold assembly until snug, then tighten
with a wrench 1/2 to 1 full turn.
WARNING:
Do not useTeon tape or pipe joint compound

13. Reinstall the gas manifold assembly to the burner assembly
with the 4 screws, that were removed earlier. NOTE: It is
important that the center of the orifices are aligned with
the center of the burners.
14. Reconnect the gas piping to the gas valve inlet.
15. Reconnect the 3-wire connector to the gas valve terminal.
Converting the Gas Valve
IMPORTANT NOTES:
• WhenconvertingtoLP/Propanegasfromnaturalgas,
thespringsfromgasvalvemustbereplacedbythe
largerspringsfromthekit.TheLP/Propanesprings

1. Remove the HIGH fire cap screw. See Figure 2.
2. Remove and discard the HIGH fire adjustment screw from
the gas valve.
3. Remove the spring from the gas valve and discard.
4. Install a larger spring from the conversion kit.
5. Install a new adjusting screw from the kit.
6. Repeat steps 1 - 5 for replacement of the LOW fire spring
and adjustment screw.
7. Check and adjust the regulator setting. See Gas Pressure
Adjustment Section.
8. Reinstall the cap screws on the HIGH and LOW regulators.
Plastic replacement cap screws are provided in the
conversion kit.
9. Affix the yellow label from the spring conversion kit to the
gas valve.
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 2.
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. 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. Remove the cap screw (Figure 2, page 3).
2. Using a screwdriver or Allen wrench (where appropriate),
slowly turn the adjustment screw till the appropriate manifold
pressure listed in Table 2 is achieved.
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.
3. Replace and tighten the cap screw or the plastic cap 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.
