INSTALLATION INSTRUCTIONS

ATTENTION INSTALLING PERSONNEL

As a professional installer, you have an obligation to know the product better than the customer. This includes all safety precautions and related items.

Prior to actual installation, thoroughly familiarize yourself with this Instruction Manual. Pay special attention to all safety warnings. Often during installation or repair, it is possible to place yourself in a position which is more hazardous than when the unit is in operation.

Remember, it is your responsibility to install the product safely and to know it well enough to be able to instruct a customer in its safe use.

Safety is a matter of common sense...a matter of thinking before acting. Most dealers have a list of specific good safety practices...follow them.

The precautions listed in this Installation Manual are intended as supplemental to existing practices. However, if there is a direct conflict between existing practices and the content of this manual, the precautions listed here take precedence.

IMPORTANT INFORMATION

WARNING”

“This conversion kit shall be installed by a qualified service agency in accordance with the manufacturer’s instructions and all applicable codes and requirements of the authority having jurisdiction. If the information in these instructions is not followed exactly, a fire, explosion or production of carbon monoxide may result causing property damage, personal injury or loss of life. The qualified service agency is responsible for the proper installation of this kit. The installation is not proper and complete until the operation of the converted appliance is checked as specified in the manufacturer’s instructions supplied with the kit.”

CARBON MONOXIDE POISONING HAZARD

Special Warning for Installation of Furnaces or Air Handling Units in Enclosed Areas such as Garages, Utility Rooms or Parking Areas

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.

B10259-216

WARNING

TO AVOID PERSONAL INJURY, PROPERTY DAMAGE OR DEATH, DUE TO LEAKING GAS, CONTACT YOUR PROPANE SUPPLIER ABOUT INSTALLING A GAS DETECTING WARNING DEVICE. IRON OXIDE (RUST) CAN REDUCE THE LEVEL OF ODORANT IN PROPANE GAS. A GAS DETECTING DEVICE IS THE ONLY RELIABLE METHOD TO DETECT A PROPANE GAS LEAK.

BEFORE BEGINNING CONVERSION:

VALVE IDENTIFICATION

Before beginning conversion, the type valve you have must be identified. Compare the gas valve presently on the equipment to the drawing below to identify the correct valve you are working with. Page numbers for the instructions for that valve are below each drawing.

CONVERSION INSTRUCTIONS

NOTE: For low NOx models, see page 6 for NOx screens.

1.Turn off gas supply to the furnace.

2.Turn off the electrical power to the furnace.

3.Remove the furnace control access panel.

4.Separate the gas supply union and remove associated downstream piping.

NOTE: Always use a backup wrench when removing or replacing piping to avoid any undue strains or rotation of controls.

5.Remove the wires from the gas valve.

6.Remove the 4 sheet metal screws that fasten the manifold/ gas valve assembly to the burner box.

7.Visually inspect orifices for damage and drill size (marked on face with a 55) before installation. Using the 7/16" wrench, remove all existing natural gas orifices and replace with the appropriate marked 55 L.P. gas orifices contained in this kit. Tighten the orifices to prevent gas leaks, but do not overtighten. Retain the natural gas orifices for future reconversion.

8.Reinstall the manifold/gas valve assembly into the appliance. Rewire the gas valve.

9.Using a 3/32” Allen wrench, loosen the inlet and outlet pressure tap screw one (1) turn only (DO NOT REMOVE). Attach a length of 5/16” hose to each of the pressure taps. Connect the 5/16” hose to two (2) separate manometers or other adequate gauges having a scale range of at least 0” to 15” of water column.

10.Using a flat blade screwdriver, remove the regulator cover screw.

11.Using a flat blade screwdriver, remove plastic regulator adjustment screw located beneath the cover screw.

12.Remove the natural gas regulator spring from the regulator sleeve.

13.Insert the kit (P/N B1880007, WR F92-0999) provided L.P. regulator spring into the regulator sleeve.

14.Replace the regulator adjustment screw.

15.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.

16.Turn on the gas supply and check for leaks.

17.Turn on the electrical supply.

18.Adjust the room thermostat to allow for constant operation.

19.If you have the correct manifold pressure and the burners do not light, there may be air trapped in the lines. Follow these instructions:

To check for air trapped in the supply line: Verify line pressure is in the correct range. If manifold pressure is indicated during the ignition trial, the valve is opening and air may be in the line.

Units with hot surface ignitors: The valve will not open until the ignitor is at the proper temperature (glowing brightly).

Units with spark ignition: The valve will open as soon as the spark starts. If no manifold pressure is indicated during the trial for ignition, please return to step 13 to ensure the correct spring was used and to ensure the regulator adjustment is near the bottom of the adjustment range.

20.If gas inlet pressure falls outside the range of 11” and 13” W.C. after the unit has been in operation for 15 minutes, adjust the gas supply pressure (not manifold pressure), check piping size, etc., and/or consult with local utility.

NOTE: Any other gas-fired equipment should be ON before any adjustments are made.

21.Check manifold pressure. For propane gas, the manifold pressure must be between 9.5” and 10” W.C.
