IMPORTANT: All manufacturer products meet current Federal OSHA Guidelines for safety. California Proposition 65 warnings are required for certain products, which are not covered by the OSHA standards.
California's Proposition 65 requires warnings for products sold in California that contain, or produce, any of over 600 listed chemicals known to the State of California to cause cancer or birth defects such as fiberglass insulation, lead in brass, and combustion products from natural gas.
All “new equipment” shipped for sale in California will have labels stating that the product contains and/or produces Proposition 65 chemicals. Although we have not changed our processes, having the same label on all our products facilitates manufacturing and shipping. We cannot always know “when, or if” products will be sold in the California market.
You may receive inquiries from customers about chemicals found in, or produced by, some of our heating and air-conditioning equipment, or found in natural gas used with some of our products. Listed below are those chemicals and substances commonly associated with similar equipment in our industry and other manufacturers.
• Glass Wool (Fiberglass) Insulation
• Carbon Monoxide (CO)
• Formaldehyde
• Benzene More details are available at the Websites for OSHA (Occupational Safety and Health Administration), at www.osha.gov
and the State of California's OEHHA (Office of Environmental Health Hazard Assessment), at www.oehha.org. Consumer education is important since the chemicals and substances on the list are found in our daily lives. Most consumers are aware that products present safety and health risks, when improperly used, handled and maintained.

SYSTEM OPERATION INFORMATION
IMPORTANT: THIS FURNACE WAS DESIGNED TO OPERATE ON 110-125 VOLTS SUPPLIED BY A COMMERCIAL POWER UTILITY.
IMPORTANT: CONNECT THIS FURNACE ONLY TO GAS SUPPLIED BY A COMMERCIAL UTILITY.
1. Keep the air filters clean. Your heating system will operate more efficiently and provide better heating, more economically.
2. Arrange your furniture and drapes so that the supply air registers and the return air grilles are unobstructed.
3. Close doors and windows. This will reduce the heating load on your system.
4. Avoid excessive use of exhaust fans.
5. Do not permit the heat generated by appliances such as televisions, lamps, or radios to influence the thermostat operation.
6. If you desire to operate your system with constant air circulation, consult your thermostat manual or obtain advice from your HVAC professional, service agency or the gas supplier. When continuous fan is used, the indoor fan will shut-off on a call for heat. This allows the heat exchanger to warm up.
7. Do not close off any supply or return registers.
During the heating season the operation of the warm air furnace is automatic. Your HVAC professional, service agency or the gas supplier has

provided a wall mounted thermostat which is sensitive to the change in temperature of the air moving around the thermostat. Your thermostat may have switches to select some or all of the following functions:
HEAT - Turns heating on when temperature drops below the desired temperature.
IMPORTANT: DO NOT RUN A FLEXIBLE GAS CONNECTOR INSIDE THE UNIT. Extend the 1/2” black pipe from the gas valve to the union outside of the cabinet.
COOL - Turns cooling on when temperature rises above the desired temperature.
AUTO - Turns cooling or heating system on as required to maintain the desired temperature.
NOTE: Have your HVAC professional instruct you on the proper operation of your system and filter location.
that carries the cooled or heated air. To maintain efficiency, comfort and good indoor air quality, it is important to have the proper balance between the air being supplied to each room and the air returning to the cooling and heating equipment.
Proper balance and sealing of the duct system improves the efficiency of the heating and air conditioning system and improves the indoor air quality of the home by reducing the amount of airborne pollutants that enter homes from spaces where the ductwork and / or equipment is located. The manufacturer and the U.S. Environmental Protection Agency’s Energy Star Program recommend that central duct systems be checked by a qualified contractor for proper balance and sealing.
