Start the furnace and measure the time required to burn one cubic foot of gas. Prior to
checking the furnace input, make certain that all other gas appliances are shut off, with
the exception of pilot burners. Time the meter with only the furnace in operation.
IMPORTANT NOTE FOR ALTITUDES ABOVE 2,000 FEET (610 METERS): The main
burner orifices in your furnace and in these kits are sized for the nameplate input and
intended for installations at elevations up to 2,000 feet in the USA or Canada, or for ele-
vations of 2,000 - 4,500 feet (610 -1,373 meters) in Canada if the unit has been derated
at the factory. For elevations above 2,000 feet (610 meters)
IN THE USA ONLY (see
ANSI-Z223.1), the burner orifices must be sized to reduce the input 4% for each 1,000
feet (305 meters) above sea level.
NOTICE: DERATING OF THE HEATING INPUT FOR HIGH ALTITUDE IN THE FIELD
IS UNLAWFUL IN CANADA (REFER TO CAN/CGA 2.17). UNITS INSTALLED IN
ALTITUDES GREATER THAN 2,000 FEET (610 METERS) MUST BE SHIPPED FROM
THE FACTORY OR FROM A FACTORY AUTHORIZED CONVERSION STATION
WITH THE HEATING INPUT DERATED BY 10% SO AS TO OPERATE PROPERLY IN
ALTITUDES FROM 2,000 - 4,500 FEET (610 - 1,373 METERS).
E.CONDENSATE DRAIN
The evaporator coil condensate drain ends with a threaded 3/4” nominal PVC stub. A
trap is built in for proper condensate drainage and to prevent debris from being drawn
into the unit. Do not connect the drain to a closed sewer line. Connection to a vented
sewer line is allowed. It is recommended that a PVC cement not be used so that the
drain line can be easily cleaned in the future.
IMPORTANT: DO NOT INSTALL AN EXTERNAL TRAP. DOING SO CAN CAUSE
IMPROPER DRAINAGE OF THE CONDENSATE AND RESULT IN FLOODING WITH-
IN THE UNIT.
