Sealey IR37 - Manual (Page 4)

Use only original equipment replacement parts. Isolate power before any maintenance. The use of alternate or third party components
can cause unsafe operating conditions, and will invalidate the warranty. We suggest following a maintenance schedule as follows.
6.1. Fuel/Fuel Tank - Flush every 200 hours of operation or as needed. DO NOT use water to flush the tank. Use fresh kerosene/paraffin/diesel
only.
6.2. Filters - The Fuel Filter and Oil Filter should be cleaned at least twice per heating season by rinsing them in clean kerosene/paraffin/diesel.
This procedure should also be followed if the fuel is found to be contaminated (Fig.5).
6.3. Nozzle - Nozzles should be cleaned or replaced at least once per heating season. This procedure should also be followed if the fuel is found
to be contaminated.
6.3.1. To clean dirt from nozzle, blow compressed air through nozzle front. It may be necessary to soak the nozzle in clean kerosene/paraffin/diesel
to help loosen any particles (Fig.6).
6.4. Spark Plug - Clean and re-gap every 600 hours of operation, or replace as needed (Fig.7).
6.4.1. After removing the Spark Plug, clean the terminals with a wire brush.
6.5. Photocell - The Photocell should be cleaned at least once per heating season or more depending on conditions.
6.5.1. Isolate power before using a cotton swab dipped in water or alcohol to clean the lens of the Photocell (Figs.8 and 9).
6.6. Long Term Storage.
6.6.1. Unscrew the Drain Bolt and drain fuel into a suitable container (Fig.10).
6.6.2. Using a small amount of kerosene/paraffin/diesel, rinse and swirl the fuel around the fuel tank. Empty the tank completely.
6.6.3. Never store leftover kerosene/paraffin/diesel over the summer. Using old fuel can damage the heater.
6.6.4. Store heater in a dry, well ventilated area.
6.6.5. Be sure that the storage area is free of dust and corrosive vapours. Repack the
heater in the original shipping material. Keep this User’s Manual in an easily
accessible place.

5.5.5. When switching from one heat level to another during operation, it may cease operating and go into the misfire sequence. If this happens,
turn the power knob to the " O" position and immediately turn it to the desired heat level.
Note: The electrical components of this heater are protected by a fuse mounted in the PCB. If the heater fails to fire, check this fuse first,
and replace if necessary. Also check the power source to ensure that the correct voltage is being provided to the heater.
5.6. Tilting Feature.
5.6.1. Loosen the hand screws on the main frame of the heater, position the heater in the desired position, and tighten the hand screws to secure
the heater in the tilted position.
5.7. To Stop the Heater.
5.7.1. Turn the power knob to the " O" position. Combustion will stop, and the Cooling Cycle (approx. 5 minutes in duration) will begin.
5.7.2. When the Cooling Cycle is completed (fan stops running), it is safe to unplug the heater.

WARNING! Unplugging the heater before the Cooling Cycle has finished may cause overheating, possible damage to the heater
and heat plate, and will invalidate the warranty.
5.8. To Restart the Heater.
5.8.1. Wait ten seconds after the cooling cycle has completed.
5.8.2. Turn the power knob to the position and wait 10 seconds before adjusting heat level if required.
5.8.3. Be sure to follow all starting procedure precautions.
