CARBON MONOXIDE POISONING HAZARD
B10259-216
Carbon monoxide producing devices (such as an automobile, space heater, gas water heater, etc.) should not be operated in enclosed areas such as unventilated garages, utility rooms or parking areas because of the danger of carbon monoxide (CO) poisoning resulting from the exhaust emissions. If a furnace or air handler is installed in an enclosed area such as a garage, utility room or parking area and a carbon monoxide producing device is operated therein, there must be adequate, direct outside ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which can occur if a carbon monoxide producing device continues to operate in the enclosed area. Carbon monoxide emissions can be (re)circulated throughout the structure if the furnace or air handler is operating in any mode.
CO can cause serious illness including permanent brain damage or death.
Special Warning for Installation of Furnaces or Air Handling Units in Enclosed Areas such as Garages, Utility Rooms or Parking Areas
The following tools and supplies are required:
2 – Pipe wrenches, properly sized to accommodate the gas piping and connectors
1 – 1/4” nut driver
1 – manometer to read inlet and outlet pressure of the gas valve (Minimum range: 0”-20” W.C.)
Pipe joint compound or pipe thread tape that is approved for use with L.P. gas
Gas leak detection solution like a soap and water solution. Always wipe the solution from the joints when testing is completed.
WARNING
never use an open fLame to check for gas Leaks.
Prior to performing this conversion, refer to the National Fuel Gas Code (NFPA 54-02) or in Canada, CAN/CSA-B149.2-05 to ensure that the installation is in compliance with those and all local codes.

7. Remove the pressure switch hose connected to the gas valve.
8. Remove the 4 sheet metal screws that fasten the manifold/ gas valve assembly to the burner box.
9. Remove the natural gas valve (0151M00024) and retain for possible future reconversion to natural gas.
10. Remove old pipe joint compound and any debris from end of manifold.
11. Apply a liberal amount of pipe joint compound or pipe thread tape to the threads and install L. P. gas valve (0151M00025). Tighten the valve to prevent gas leaks, but do not overtighten. NOTE: the pipe joint compound or pipe thread tape must be resistant to L.P. gas.
12. Visually inspect orices for damage and drill size (marked
on face with 1.25mm) before installation. Using the 7/16”
wrench, remove all existing #45 natural gas orices and replace with the appropriate 1.25mm L.P. gas orices con­tained in this kit. Tighten the orices to prevent gas leaks, but do not overtighten. Retain the natural gas orices for
future reconversion.
13. Install completed L.P. manifold/valve assembly back into
the unit. Be sure to align the orices i n the burner opening.
Fasten with 4 sheet metal screws retained from Step 8.
14. Reattach the pressure switch hose to the gas valve.
15. Reattach the wiring to the gas valve and wire tie any loose wires to avoid contact with hot or moving parts.
16. Apply a liberal amount of pipe joint compound or pipe thread tape to the threads and reassemble the piping previously removed. NOTE: the pipe joint compound or pipe thread tape must be resistant to L.P. gas.
17. Connect a calibrated water manometer (or appropriate gas pressure gauge) at either the gas valve inlet pressure
boss or the gas piping drip leg. See gas valve gure for
location of inlet pressure boss.
