HEALTH & SAFETY INFORMATION

GENERAL HEATER SAFETY  WARNING

WARNING: Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire  and/or serious injury.
Save all warnings and instructions for future reference.

1. Work area safety
   a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
   b) Do not operate heaters in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Heaters create sparks which  may ignite the dust or fumes.
   c) Keep children and bystanders away while operating a heater. Distractions can cause you to lose control.

2. Electrical safety
   a) Heaters plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) heaters.  Unmodified plugs and matching outlets will reduce risk of electric shock.
   b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
   c) Do not expose heaters to rain or wet conditions. Water entering a heater will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the heater. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   e) When operating a heater outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
   f) If operating a heater in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3. Personal safety
   a) Stay alert, watch what you are doing and use common sense when operating a heater. Do not use a heater while you are tired or under the  influence of drugs, alcohol or medication. A moment of inattention while operating heaters may result in serious personal injury.
   b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or  hearing protection used for appropriate conditions will reduce personal injuries.
   c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source.
   d) Remove any adjusting key or wrench before turning the heater on. A wrench or a key left attached to a rotating part of the heater may result  in personal injury.
   e) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can get sucked into the in moving parts of the heater.

4. Heater use and care
   DO NOT move the heater when it is in operation or when plugged into the mains supply. Only move heater once it has cooled and it has been unplugged.
   a) Use the correct heater for your application.
   The correct heater will do the job better and safer at the rate for which it was designed.
   b) Do not use the heater if the switch does not turn it on and off. Any heater that cannot be controlled with the switch is dangerous and must  be repaired.
   c) Disconnect the plug from the power source before making any adjustments. Such preventive safety measures reduce the risk of starting the  heater accidentally.
   d) Store idle heater out of the reach of children and do not allow persons unfamiliar with the heater or these instructions to operate the heater. Heaters are dangerous in the hands of untrained users.
   e) Maintain heaters. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the heaters operation. If damaged, have the heater repaired before use. Many accidents are caused by poorly maintained heaters.
   g) Use the heater, in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the  heater for operations different from those intended could result in a hazardous situation.

5. Service
   a) Have your heater serviced by a suitably qualified repair person using only identical replacement parts. This will ensure that the safety of the  heater is maintained.

6. Use in environments with no permanent presence of people.
   • Warning posters must be displayed prohibiting people from being permanently in that room.

PREPARING THE SPACE HEATER

GUIDELINES OF FUEL GASES – FIG. 1

This heater is intended for the use of temporary heating of buildings under construction, alteration or repairing, in accordance with BSEN449:2002+A1:2007(E). There may also be other local standards or regulations governing the use of fuel gases and heating products, of which you can get advice from your relevant local authority.
Propane and butane belong to the odorless fuel gases family. Normally gas suppliers will add an odor-making agent to help you detect a gas leakage. However, the odor added can fade over time. Fuel gases maybe present even though no odor exists.
These heaters are intended for use with Propane (I3P) or Butane/Propane mixes (I3B/P). Any other fuel gas is considered misuse and dangerous. To check the leakage of propane/butane please use a professional gas leakage detector or simply with soap and water solution. Never check with a  flame! Propane and butane are heavier than air. If there is a leakage, it sinks to the lowest possible level, collecting there with the surrounding air,  forming a potentially explosive mixture. It is prohibited to use these gas heaters in high rise flats, bedrooms, bathrooms, basements or below ground level.

VENTILATION – FIG. 2

WARNING:
Be sure that the heater is only ever used with correct ventilation. Make sure that no object may obstruct the fan air intake. (Fig.2.)
OXYGEN DELETION:
The combustion of propane will consume a lot of oxygen (with butane even more). The minimum ventilation required by these heaters is 30cm3  per kW heat output is strongly recommended. Never use the heater in an enclosed space.
CARBON MONOXIDE (CO) POISIONING:
Even though the direct-fired system of this heater operates very close to 100% combustion efficiency, it still generates small amounts of CO. Some  people are more affected by CO than others. The symptoms of CO sensitivity are headache, dizziness, burning eyes and nose, nausea, dry mouth or  sore throat, etc. Be sure to follow advice about ventilation.

PREPARING FOR OPERATION – FIG. 3

Check the heater thoroughly for damage. Do not use a damaged heater. Be sure the heating area is adequately ventilated, free of moisture and dust,  far away from any combustible material. Always put the gas cylinder behind the heater in a stable position. Never put the gas cylinder in front of the heater (Fig.3.).
IMPORTANT: Locate heater at a safe distance from any combustible materials. (Fig.4.)
Check the outlet pressure of the gas regulator and gas hose according to the specification on the rating plate. Use only BS 3016 approved gas  regulator and BS 3212 approved gas hose. Gas hose should be in its natural form without excessive bending and not twisted or kinked, ensure all  connections are gas tight.
WARNING: When connecting to the gas cylinder, ensure the area is flame free to prevent risk of explosion. Screw fasten the gas hose with  regulator to the cylinder valve. Ensure the connection is tight.
NOTE: The gas connection to the heater has a left hand thread.
WARNING: Do not adjust regulator.
Screw fasten the gas hose to the heater ensuring that the rubber hose is not twisted or kinked. Ensure the connection is gas tight.

OPERATING INSTRUCTIONS FOR 17681/17682.

VENTILATION – FIG. 5

WARNING: PROVIDE AT LEAST A 1.5 FT² (1400 CM²) OPENING OF FRESH, OUTSIDE AIR WHILE RUNNING HEATER. IF  PROPER FRESH, OUTSIDE AIR VENTILATION IS NOT PROVIDED, CARBON MONOXIDE POISONING CAN OCCUR. PROVIDE  PROPER FRESH, OUTSIDE AIR VENTILATION BEFORE RUNNING HEATER

STARTING PROCEDURE

WARNING: BEFORE STARTING THE HEATER, YOU MUST ENSURE THAT THE MINIMUM VENTILATION REQUIREMENTS  ARE OBSERVED TO AVOID THE RISK OF CARBON MONOXIDE POISONING.
TO START THE HEATER

1. Follow all installation, ventilation, and safety information.

2. Locate the heater on stable and level surface. Make sure strong drafts do not blow into the front or rear of the heater.

3. Plug the heater into a suitable 220-240V mains socket. The motor will start, the fan will turn, forcing air from the front of the heater.

4. Set the on/off switch to the on position.

5. Open the propane supply valve on the propane tank(s) slowly.
   NOTE: If not opened slowly, the excess-flow check valve on the propane tank will stop the gas flow. If this happens, close the propane supply  valve and open again slowly.
   WARNING: MAKE SURE THAT THE MOTOR AND FAN ARE RUNNING BEFORE PUSHING IN AUTOMATIC CONTROL  VALVE BUTTON. FLAMES COULD FLASH OUTSIDE HEATER IF THE MOTOR AND FAN ARE NOT RUNNING.

6. Push in and hold the automatic control valve button 4 .

7. Push the piezo ignitor button 5.
   • You may need to push the piezo ignitor button 3-8 times until the burner lights.
   • When the burner lights. keep the automatic control valve button pushed in.

8. Release the automatic control valve button after 30 seconds.

NOTE: If the heater fails to ignite, the hose may have air in it. If so, keep the automatic control valve button pressed and wait 20 seconds. Release the automatic control valve button and wait 20 seconds for unburned fuel to exit the heater, repeat steps 6-8.
NOTE: If the heater is unplugged or a power outage occurs while the heater is running, the thermal limit device will stop fuel flow. A few seconds occur before the thermal limit device activates. During this short time, flames may appear outside the heater. This is normal. The flames will go out when thermal limit device activates.

SHUT-DOWN PROCEDURE

TO STOP THE HEATER

1. Tightly close propane supply valve on propane tank(s).
   • The heater will burn away gas left In supply hose.

2. Allow the heater to cool down for 5 minutes, then switch off the heater.

3. Unplug the heater.

TO RESTART THE HEATER

1. Wait five minutes after stopping the heater.
2. Repeat steps under ‘To Start The Heater’.

OPERATING INSTRUCTIONS FOR 17684/17685.

IGNITION SYSTEM – FIG. 6

Ignition is automatic with this heater as soon as the gas valve button is depressed, with a continuous spark from the spark plug igniting the gas. As the thermocouple heats up, a low voltage is fed to the Flame Failure valve, causing the valve to open, so that after a few seconds, the gas valve  button may be released and the flame is established.

SAFETY CONTROL SYSTEM

Should the flame extinguish for any reason, the thermocouple will quickly cool, causing the Flame Failure valve to close, shutting off the gas supply. Similarly, should there be a power failure, causing the fan motor to stop, the Safety Shut-Off valve solenoid will become de-energised, and therefore  shut off the gas supply.
Additionally, the machine is equipped with thermal overload protection, which will intervene should the/unit overheat shutting off the electrical supply.

STARTING PROCEDURE

WARNING: BEFORE STARTING THE HEATER, YOU MUST ENSURE THAT THE MINIMUM VENTILATION REQUIREMENTS  ARE OBSERVED TO AVOID THE RISK OF CARBON MONOXIDE POISONING.

1. Ensure there is sufficient gas and that it is correctly connected.
2. Open the supply valve on the gas cylinder, and fully open the regulator valve adjacent to the gas inlet pipe.
3. Plug the heater in to a suitable power supply.
4. Set the flame intensity control valve (4) , to a low setting.
5. Set the fan switch (1) to the ON (I) position. Confirm the fan operates.
6. Hold in the gas valve button (3) , until the thermocouple is energised and the heater ignites.
7. If the heater fails to ignite, there may be air in the hose so keep the fuel valve open and wait for about 15 seconds. Walt 30 seconds for  unburned fuel to exit the heater. Repeat the step above.
8. When the burner remains lit set the heater at the required level by turning the flame intensity control valve counter-clockwise. If the burner  goes out. turn off the gas. Turn the gas valve fully clockwise to its lowest position. Check the fuel supply. If adequate fuel is available, re-start  the heater from step 1.

Should the flame extinguish when the ignition button is released, wait for 1 minute, before repeating the operation.

• Turning the flame intensity control valve anti-clockwise will increase the gas supply and therefore the output clockwise to decrease. If ignition  is difficult or irregular; ensure the fan is operating and that the air inlet and outlet are completely clear. Also ensure that the electrode gap is  correct and that the electrode is clean (see Maintenance).

IMPORTANT: Should the thermal overload protection feature operate and the spark plug is seen to be operating, shut off the gas supply and  allow the unit to cool for at least 10 minutes with the fan running, before attempting to relight the burner. Should the flame safety valve operate, the heater may be restarted once the cause of the problem has been found and rectified.

SHUT-DOWN PROCEDURE

1. Turn off the gas at the propane cylinder valve(s).
2. Let the heater run while any gas left in the supply hoses is burnt off.
3. Allow the fan to run for 2 – 3 minutes with the burner off, in order to allow the casing to cool down and the fan to disperse any residual gas.
4. Switch off the fan and unplug from the electrical supply.
5. Disconnect the gas supply.

MAINTENANCE AND STORAGE

Regular inspection and cleaning reduces the necessity for maintenance operations and will keep your heater in good working condition.
The motor must be correctly ventilated during the heater’s operation. For this reason avoid blocking the air inlets.
If the replacement of the supply cord is necessary, this has to be done by the manufacturer or his agent in order to avoid a safety hazard.
Remove the plug from the socket before carrying out any adjustment, servicing or maintenance.

• Keep the heater clean, especially the motor grid and fan blades.
• Store the heater in a dry, clean and safe place away from the reach of children.
• The heater should be inspected at least once a year by a qualified person.
• Check the gas hose and its screw connections frequently.
• Repair can only be made by a suitably trained and qualified person.
