• When cleaning, make sure that water does not enter the unit.
• Do not open the enclosure to clean the inner parts. Do not spray water into the
heater.
• Never use solvents, gasoline, toluene and similar aggressive chemicals to clean
the heater.
Regularly wipe the enclosure using a soft sponge or cloth. For very dirty parts, use a
sponge wetted with lukewarm water and a mild detergent, then dry using a clean
cloth. Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow
compressed air through air inlet. Regularly inspect the power cable: if worn, cracked
or damaged have it replaced by a qualied persons only.
Before storing the heater, make sure it is perfectly cool and dry. Cover the unit with a
blanket or tarp and store it in a dry, ventilated plac
The following checks are recommended before every seasonal use:
Nozzle
Carefully unscrew nozzle from nozzle tting. Blow compressed air through nozzle
orice to free it from dirt. Replace nozzle if necessary.
Air Filters
Clean air lters. Remove lter end cover (11), wash air intake lter (10) using a light
detergent and dry it thoroughly before re-installing. Replace air delivery lter (9) once
a year (Fig.3)

5. CLEANING, MAINTENANCE & STORAGE - CON
Air Pump Pressure Adjustment (Fig 4.)
The Air Pump pressure is factory set and must be checked and adjusted by qualied
technicians only. Tampering with the unit may be dangerous.
Remove pressure gauge cap. Connect a pressure gauge on the pressure measuring
port on the rear guard. Start heater and read air pressure value. If necessary adjust
pressure to the correct value turning the adjusting screw (the air vent hole in the
adjusting screw middle) clockwise to increase, anticlockwise to decrease the
pressure:
Ignition Electrodes (qualied perons only)
Clean, adjust, & if necessary replace ignition electrode. For electrode gaps see Fig.4-
