INTRODUCTION

The JETFIRE range of portable heaters has been designed to give safe, efficient and reliable service when the correct operating sequences are followed and proper attention is given to cleaning and maintenance procedures. This manual is to provide up to date information necessary to the user/serviceperson for operating, cleaning and servicing the heaters, together with fault finding techniques and general specifications details and diagrams. Please note that the information given herein after may be subject to revision in compliance with the policy of continual improvements. The JETFIRE range of heaters should only be used in the manner and purpose for which they were intended and in accordance with the recommendations and safety precautions detailed in the following Manual and in the Operating Instructions stickers on the unit itself. All JETFIRE heaters undergo rigorous safety and operational tests before being despatched into the marketplace however it is still imperative that prior to use, all operators have read and understood all information and instructions provided and are aware of possible hazards

IMPORTANT SAFETY INSTRUCTIONS & PRECAUTIONS

This booklet contains important information for the use and safe operation of this heater. Please read and understand all warnings before you start using the unit.

WARNING: When using this heater:

1. Read all instructions before using this heater.

2. Know how to start and stop the unit. Be quite familiar with the controls.

3. Follow the maintenance procedures and fault finding techniques outlined in the manual.

4. Do not restrict under any circumstances either the inlet or outlet end of the heater.

5. Do not operate this heater in basements or below ground.

6. Permanent ventilation to the outside atmosphere must be provided as listed in the technical specifications divided equally between

floor and high levels.

7. Allow a minimum room size as listed in the technical specifications.

8. The heater must not be used in close proximity to combustible material. A guard must be placed 900mm away from the heater outlet

to prevent the approach of combustible materials.

9. Under no circumstances should the heater hot air flow be directed towards the gas cylinder even if the cylinder is ‘FREEZING’.

10. Installation and storage of gas cylinders must be in accordance with local regulations.

11. Read carefully the instructions concerning earthing and gas cylinders. Use only propane vapour off-take cylinders.

12. Do not pull on the electrical cord in order to unplug the unit.

13. Do not effect temporary repairs on worn or damaged electrical cords and plugs. Have worn, cut or damaged cords and plugs

replaced by an authorised service person/electrician.

14. To prevent injury always disconnect the power plug before disassembling any part of the heater, effecting any servicing or when the

unit is not in use.

15. Local regulations should be followed as to the installation of industrial heaters.

ELECTRICITY SUPPLY

The JETFIRE range of heaters is designed to run off 220-240V Single Phase 50-60Hz electrical supply. The unit should be plugged into a 10A outlet. WARNING: This appliance must be earthed. Note: If the Plug needs to be replaced to suit local requirements a qualified electrician should carry out the replacement taking care to earth the unit and maintain the correct phase connection as per the wiring diagram.

GAS SUPPLY

If the heater is run continuously on full output frost might form on the GAS cylinder indicating it is starting to “FREEZE”. This condition is caused by excessive vapour withdrawal and can be overcome by using various sizes of cylinders or multiple cylinder combinations. To minimise the “FREEZING” effect we suggest our heaters be connected to a minimum size and quantity of Gas cylinders as follows:

• J8/15 1 X 9KG CYLINDER ( Minimum only – increase bottle size/number if using in low temperatures)

• J25/33 1 X 45KG CYLINDER ( Minimum only – increase bottle size/number if using in low temperatures)

• J50/70/90 3 X 45KG CYLINDERS ( Minimum only – increase bottle size/number if using in low temperatures)

UNDER NO CIRCUMSTANCES SHOULD THE HOT AIR FLOW FROM THE HEATER BE DIRECTED TOWARDS THE GAS CYLINDER TO AVOID THIS “FREEZING”.

WARNING: Propane Gas Cylinders must be installed and stored in accordance with current local requirements. Propane Gas Cylinders should always be installed connected and replaced in a flame free atmosphere. Use Propane vapour off-take cylinders only.

MAINTENANCE

After every heating season, or sooner if used in a dirty environment, carry out the following maintenance procedures on your heater.

GENERAL

Disconnect the heater from the electricity main power socket and from the gas cylinder. Remove the screws retaining the cover and remove the cover.

BURNER SERVICE

Remove the retaining clip (39) and remove the gas jet assembly from its seat. Remove the gas jet (40). Check it and clean it by blowing in the opposite direction to the gas flow. Remove the combustion chamber assembly (be careful to remove all screws/bolts and electrical connections holding it to the rest of the heater) and remove the burner head assembly from it. Clean the burner head assembly by using an airline. Where fitted check the flame detecting probe, ignition electrode and thermocouple for positioning, wear and cracks referring to the drawing attached.

Check and clean (or replace if necessary) the filter fitted in the nipple (14) of the heater. Reassemble the above using reverse order and remake any threaded joints in the gas line using Loctite 577.

GAS SUPPLY

Check the tightness on the gas supply hose and check pipe connections in the gas line. PROPANE gas has a distinctive smell and leaks can usually be detected immediately by this fact. If a leak is suspected extinguish all naked flames and close the cylinder valve. Never look for a leak using a naked flame but trace by

smell and confirm by brushing a soap solution over the suspected leak. Remake any threaded joint in the gas line using

Loctite 577.

ELECTRICAL

Check that the motor fixing bolts are tight and make sure that the fan fixing screw at the fan boss is tight. Check the limit thermostat junction for continuity. Check that all electrical connections are tight and in good condition.

GENERAL

Reassemble the heater making sure all screws and fittings are tight. Reconnect and start the heater following the installation and operating instructions. Test the heater for correct operation making sure that all safety mechanisms (where fitted thermocouple, flame detecting probe, air proving switch, limit thermostat) are operating correctly.
