Table 2. Gas Orifice Kits, Contents by Part Number
NOTE: The ve critical parts are not available individually but only as part of the complete Fuel Orice kit listed. Select the correct fuel type and heater
BTU Capacity from Table 2. The Orice Kit listed will come with the ve (5) critical components as indicated (1) - (5). Always ensure that all ve critical components are correct for the heater fuel type and BTU model. Use the identifying color and markings listed in the chart for each component to verify they are correct before installing, repairing, or operating the heater. High Altitude: Derating for high elevation is not necessary with the JXi heater because of its venturi-type combustion system which self- compensates for changes in barometric pressure. Air ow through the blower inlet pulls the correct ow of gas into the burner regardless of air density. Proper combustion and high efciency are assured without special adjustment or changes to the heater.

IMPORTANT: READ BEFORE YOU START
1. Gas Orifice
The orifice is specific for each BTU and for fuel type. Ensure you have
the correct gas orifice for the BTU and fuel type required by checking
the part number factory-stamped on the gas orifice against Gas Orifice
Markings column, Table 2. It is also critical that the O-ring used is
the one provided by Zodiac®in this kit and is BUNA-N type (no
substitutions).
2. Air Orifice
The air orifice is specific for each BTU and fuel type. Ensure you
have the correct air orifice for the BTU size and fuel type required
by checking the part number factory-molded on the air orifice and its
color against Air Orifice Color/Markings column, Table 2.
3. Fuel Line Sealing Grommet
The inlet fuel grommets are color coded to provide a visual indication
of the heater’s pre-conversion fuel type. Ensure you have the correct
gas supply sealing grommet for the fuel type by checking the color and
fuel type factory-molded on the grommet against Gas Supply Sealing
Grommet Color/Markings column, Table 2.
4. Rating Plate Sticker and Prepaid Mail-In Card
The rating plate sticker is factory-applied to the heater on the outside
of the combustion chamber (see Figure 1). It is critical that the rating
plate matches the gas and air orices installed in the heater and
accurately reects the BTU size and fuel type. If the heater is being
converted, the new rating plate (included in this kit) MUST be placed
on the combustion chamber over the original rating plate with the
heater model number and serial number visible (see Figure 2).
