9. Reconnect the gas piping and electrical wires to the
gas valve.
10. Open the manual shut-off valve and follow the Operating
Instructions on page 19.
Measuring the Supply Gas Pressure
To obtain an accurate pressure reading, turn off all
gas appliances (i.e. Dryers, water heaters, stoves,
etc.) at their ON/OFF control or individual gas valves.
1. Remove the inlet pressure plug from the INLET side
of the gas valve with a 3/16 Allen wrench. See Figure
27.
2. Install a 1/8 NPT fitting, which is compatible with a
manometer or similar pressure gauge.
3. Connect the manometer or pressure gauge to the inlet
pressure tap.
4. Turn on all electrical power to the furnace.
5. Turn the main gas supply valve (on the outside of the
unit) to the ON position.
6. Start the furnace by adjusting the thermostat to it’s
highest setting. Allow the furnace to run for 10 minutes.
7. Check the incoming gas line pressure. Propane gas
furnaces must be between 11.0”-14.0” W.C. Natural
gas installations must be between 4.5”-10.0” W.C. If
the pressure is not between these specified ranges,
contact your local gas supplier for adjustment.
8. Adjust the thermostat to it’s lowest setting and allow
the unit to cycle off.
9. Turn the main gas supply valve (on the outside of the
unit) to the OFF position.
10. Turn off all electrical power to the furnace.
11. Disconnect the manometer or pressure gauge.
12. Remove the NPT fitting and reinstall the inlet pressure
plug. NOTE: To prevent cross threading, hand tighten
the plug first, then tighten with 3/16 Allen wrench.
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.
1. Remove the manifold pressure plug from the outlet side
of the gas valve with a 3/16 Allen wrench.See Figure
27 (page 15).
2. Install a 1/8 NPT fitting, which is compatible with a
Manometer or similar pressure gauge.
3. Connect the manometer or pressure gauge to the pipe
thread fitting.
4. Start the furnace by adjusting the thermostat 5 degrees
above room temperature. Allow the furnace to operate
for 3 minutes.
5. Measure the manifold pressure on the manometer or
pressure gauge. Compare the measured value to the
value in Table 11, (page 24), Table 12, (page 24),
or Table 13, (page 24).
6. Replace the cap so that the letters facing up represent
the type of gas being used for the furnace. See Figure
27 (page 15).
7. Adjust the thermostat to its lowest setting.
8. Turn off the main gas supply to the unit at the manual
shut-off valve, which is located outside of the unit.
9. Turn off all of the electrical power to the furnace.
10. Disconnect the manometer or pressure gauge.
11. Remove the 1/8 NPT fitting and reinstall the manifold
pressure plug. NOTE: To prevent cross threading,
hand tighten the plug first then tighten with 3/16 Allen
wrench.
STARTUP & ADJUSTMENTS
PLEASE READ ALL SAFETY INFORMATION
BEFORE LIGHTING THE FURNACE
