Journeyman Ductable Dual Fuel Indirect-Fired Heater
6. Do not locate fuel gas containers or fuel supply hoses
within 20 feet/6 meters of the heater's blower outlet.
7. Do not direct the heater toward any propane gas
container within 20 ft. (6m) of the heater's air
discharge. When ducting is attached to the heater,
the heater's hot air discharge is the end of the ducting.
8. Do not block air intakes or discharge outlets of the
heater. Doing so may cause improper combustion
or damage to heater components leading to property
damage.
9. The hose assembly shall be visually inspected on a
daily basis after heater relocation and when the heater
is in use. If it is evident there is excessive abrasion
or wear, or if the hose is cut, it must be replaced prior
to the heater being put into operation. The hose as-
sembly shall be protected from building materials, and
contact with hot surfaces during use.
10. Check for gas leaks and proper function upon heater
installation, when relocating, and after servicing.
Refer to leak check instructions within installation
section of this manual.
11. This heater should be inspected for proper operation
by a qualified service person before each use and at
least annually.
12. Always turn off the gas supply to the heater if the
heater is not going to be used.
13. This heater is wired with a ground connection for your
protection against shock hazard and must be wired
directly into a properly grounded electrical supply.
Failure to use a properly grounded electrical supply
can result in electrical shock, personal injury, or death.
14. If gas flow is interrupted and flame goes out, do not
relight the heater until you are sure that all gas that
may have accumulated has cleared away. In any
event, do not relight the heater for at least 5 minutes.
15. The heater requires a minimum 500 gallon/1892 liter
propane tank for proper gas supply pressure and
operation. A larger tank may be required depending
upon operating temperature conditions at the site.
16. When the heater is to be stored indoors, the
connection between the propane gas supply container
and the heater must be disconnected. The container
must be removed from the heater and stored in
accordance with NFPA 54 National Fuel/Gas Code,
Standard for the Storage and Handling of Liquefied
Petroleum Gases, ANSI/NFPA 58, or CSA B149.1
Natural Gas and Propane Gas Installation Code.
17. Propane gas supply containers have left handed
threads. Always use the appropriate wrench to make
a connection to tighten or loosen the pigtail
connector's P.O.L. fitting at the container's gas
supply valve.
18. The heater may start at any time when used with a
thermostat.
Safety System
High Temperature Control: The heater is equipped
with two high temperature switches designed to turn the
heater off if the internal temperature reaches an unsafe
level. These are auto reset design limit switches.
Fan Switch: Controls when to start and stop the main
motor (Pre-heat & Post Purge).
Air Pressure Switch: This component ensures that the
burner's fan motor is operating at the proper speed to
ensure a safe start up before ignition occurs.
Flame sensor: Used with the ignition control, it proves
that burner flame is established and keeps the burner in
operation as long as there is a call for heat.
