5.7.2 Turn the Power switch to "ON".
WARNING! Ensure that all pre-starting precautions are carried out.
5.8.
Monitoring the heat output
5.8.1 If, after a period of time, the heat output begins to fall this indicates that either the unit requires maintenance, as laid out in Section 6,
or that the environmental conditions the unit is operating in are not correct; read Section 5.
DO NOT ATTEMPT TO TURN UP THE AIR PRESSURE TO COMPENSATE FOR HEAT LOSS as this could result in damage to the
combustion chamber and will invalidate the warranty.
6. MAINTENANCE
WARNING! MAINTENANCE MUST ONLY BE UNDERTAKEN BY A qUALIFIED PERSON. WE STRONGLY RECOMMEND THAT
ALL SERVICING IS DONE BY YOUR LOCAL SERVICE AGENT.
IMPORTANT! We strongly recommend that you arrange for heater servicing during the summer months to avoid being left
without heat during the winter.
WARNING! Unplug unit from mains power supply before opening or servicing heater. See Section 1 regarding electrical
safety and maintenance.
6.1
General. Keep the heater clean; wipe outer case with a damp, clean cloth. DO NOT use abrasives. Oil wheels if necessary. Check
heater for damage and immediately repair or replace with authorised parts. Contact your Sealey Service Agent.
6.2
Fuel Tank (fig.7).
6.2.1
For long term storage the fuel tank will need to be drained. The tank should be flushed every 200 hours of operation or as required.
Drain the fuel into a suitable container. Using a small amount of fresh paraffin, rinse and swirl the paraffin inside the tank and then
drain fully.
6.3
Spark plug (electrode). Clean and check the plug gap every 600 hours, or replace if necessary. Clean the spark plug using a wire
brush and set the gap to 3.5mm (fig.8).
6.4
Air filter. The cast alloy compressor unit is protected by a three stage filter system (fig.9). The intake filter should be cleaned every
500 hours or more regularly if the appliance is used in a dusty environment.
6.4.1 Remove the fan guard and filter end cover.
6.4.2 Take out the intake filter, wash it using a light detergent and dry thoroughly.
6.4.3 The Output and Lint filters should be replaced every 500 hours or less if the operating conditions demand.
6.5.
Fuel filter. The fuel filter (fig.10) should be cleaned twice per season, unless contamination occurs where it will require cleaning
immediately. To clean the filter, remove and wash in paraffin.
6.6.
Nozzle. The nozzle should be cleaned or replaced at least once per heating season.
6.6.1 To clean dirt from nozzle, Unscrew the four retaining screws and hinge open the top cover of the heater.
6.6.2 Remove the burner head and remove the nozzle (fig.11).
6.6.3 Blow compressed air through the front of the nozzle. For stubborn dirt it is advisable to soak the nozzle in clean paraffin to help loosen
any particulate.
6.6.4 Refit nozzle and burner head in reverse order to above.
6.7.
Flame-out device. The AB heaters are fitted with a flame-out device (a photocell, see fig.12), which cuts the fuel supply should the
flame be inadvertently extinguished, or if the unit overheats. If this happens, switch off the heater and unplug from the mains supply.
Check the heater to determine the fault. In particular check that the air intake is not obstructed and that the internal fan is rotating
freely. Wait a few minutes and restart the unit. If the problem persists contact your local Sealey Service Agent.
6.8.
Fan. Fan blades (fig.13) should be cleaned at least once per heating season, depending on environment. Remove the outer case top
shell (fig.3) and clean the fan blades with a damp cloth. Dry fan thoroughly using compressed air.
