User’s Information

A variety of potential sources of carbon monoxide can be found in a building or dwelling such as gas-fired clothes dryers, gas cooking stoves, water heaters, furnaces and fireplaces. The U.S. Consumer Product Safety Commission recommends that users of gas-burning appliances install carbon monoxide detectors as well as fire and smoke detectors, listed by a nationally recognized agency (e.g. Underwriters Laboratories or International Approval Services), to help alert dwelling occupants of the presence of fire, smoke or unsafe levels of carbon monoxide.

NOTE:

The manufacturer of your furnace does not test any detec- tors and makes no representations regarding any brand or type of detector.

▲! WARNING

BODILY INJURY CAN RESULT FROM HIGH VOLTAGE ELECTRICAL COMPONENTS, FAST MOVING FANS, AND COMBUSTIBLE GAS. FOR PROTECTION FROM THESE INHERENT HAZARDS DURING INSTALLATION AND SERVICING, THE ELECTRICAL SUPPLY MUST BE DIS- CONNECTED AND THE MAIN GAS VALVE MUST BE TURNED OFF.

Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should install, repair or service heating equipment.

Untrained personnel can perform basic maintenance func- tions such as cleaning and replacing filters. All other opera- tions must be performed by trained service personnel.

Parts and controls of this furnace are unique. Should service or modification be required, be sure your servicer uses only factory authorized parts, kits, or accessories for this furnace.

If you experience a problem with the operation of your furnace, check the “Problem Solver” section of this manual before you call for a possibly unneeded service call.

▲! WARNING

Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. Refer to the installation instructions provided with the furnace and this manual. For assistance or additional information con- sult a qualified installer, service agency or the gas supplier.

To Start the Furnace

Lighting instructions.

Your furnace does not use a continuously burning pilot flame. Therefore, manually lighting your furnace is not required. Your furnace is equipped with an automatic ignition system. It uses a hot surface ignition device that automatically lights the burners each time the thermostat signals the furnace to start.

▲! WARNING

Do not attempt to manually light the furnace.

1.Please read all safety information in this book before operating furnace.

2.Set thermostat to lowest setting. Turn off all electric power to furnace.

3.Remove the furnace front panel to gain access to the main gas valve.

4.Turn gas cock knob clockwise or the toggle switch located on the main gas valve inside the unit to “OFF” position (see illustration on next page). If external gas cock is used, turn to “OFF” position (see illustration on next page). Allow 5 minutes for any gas within the unit to escape. LP gas being heavier than air may require forced ventilation. If you smell gas STOP! Follow the “What To Do If You Smell Gas” instructions on the front cover of this book. If you don’t smell gas, go to next step.

5.Turn gas cock knob counterclockwise or the toggle switch to “ON” marker (see illustration on next page).

6.Replace the furnace front access panel.

7.Turn on main electrical supply and set thermostat to desired setting. Combustion blower will start and ignition device will start to heat up. After approximately 15 seconds main gas valve will open and burners will ignite.

8.When thermostat is satisfied, main burners will extinguish.

9.If main burners fail to ignite, lower thermostat setting or disconnect electrical supply, wait 5 minutes, raise thermostat setting above indicated temperature.

10.If furnace will not light, turn “OFF” all gas and electric- ity to unit and call servicer or gas supplier.

For complete shutdown.

Turn gas cock knob on main gas valve to “OFF” position. Disconnect electrical supply to unit.

▲! CAUTION

If this is done during the cold weather months, provisions must be taken to prevent freeze-up of all water pipes and water receptacles.

Whenever your house is to be vacant, arrange to have someone inspect your house for proper temperature. If your furnace should fail to operate, damage could result, such as frozen water pipes.

Flame Roll-out Device.

All models are equipped with a fusible link located near the burners. In case of flame roll-out, the link will open (melt) and cause the circuit to open which shuts off all flow of gas.
