Operation; Ventilation; Theory Of Operation - Desa TA100 Manual Del Propietário

WARNING: Provide a fresh air
opening of at least three square
feet (2,800 square cm) for each
100,000 BTU/HR rating. Provide
extra fresh air if more heaters
are being used. The minimum
ventilation requirements must
be followed to avoid risks as-
sociated with carbon monoxide
poisoning. Make certain these
requirements are met prior to
operating heater.
The Fuel System: The air pump forces air
through the air line. Air is then pushed through
the nozzle. This air causes fuel to be lifted
from the tank. A fine mist of fuel is sprayed
into the combustion chamber.
The Air System: The motor turns the fan. The
fan pushes air into and around the combustion
chamber. This air is heated and provides a
stream of clean, hot air.
IMPORTANT: Review and under-
stand the warnings in the Safety
section, page 2. They are needed
to safely operate this heater.
Follow all local ordinances and
codes when using this heater.
TO START HEATER
1. Follow all ventilation and safety information.
2. Locate heater to provide maximum circu-
lation of the heated air. Follow all location
requirements noted in Safety, page 2.
3. Fill fuel tank with fuel. Use only kerosene,
#1/#2 diesel/fuel oil, JET A or JP-8 fuels to
avoid risk of fire or explosion. Never use
gasoline, oil drained from crank cases,
naphtha, paint thinners, alcohol or other
flammable fuels.
4. Attach fuel cap.
5. Plug heater's power cord into approved,
grounded, three-wire extension cord.
Extension cord must be at least six feet
(1.8 m) long.

Example: A 200,000 Btu/Hr (58.6 kw) heater
requires one of the following:
• a two-car garage door [16 feet (4.88 meter)
opening] raised 5" (12.7 cm)
• a single-car garage door [9 feet (2.74 me-
ter) opening] raised 8" (20.3 cm)
• two, 30" (76.2 cm) windows raised 15"
(38.1 cm)
The Ignition System: The high voltage ig-
nitor provides power to the spark ignitor. This
ignites the fuel/air mixture in the combustion
chamber.
The Flame-Out Control System: This sys-
tem causes the heater to shut down if the
flame goes out.
Extension Cord Size Requirement
6 to 10 feet (1.8 to 3 m) long, use 18 AWG
(0.75 mm ) rated cord
2
11 to 100 feet (3.3 to 30.5 m) long, use 16
AWG (1.0 mm
2
101 to 200 feet (30.8 to 61 m) long, use
14 AWG (1.5 mm
6. Plug extension cord into standard 120
volt/60 hertz, 3-prong grounded outlet.
7. Push ON/OFF switch to the ON (|) position.
8. Wait 10 seconds for LED to display. Adjust
thermostat by pressing
point higher. Press
perature lower. If heater set temperature is
higher than the surrounding air tempera-
ture, heater should ignite immediately. If
heater thermostat set temperature is lower
than surrounding air temperature, heater
will not ignite.
A cold heater may affect the thermostat
setting. This thermostat is a general-heat-
ing control. It is not intended for precise
temperature control. Adjust thermostat
until heater cycles at the desired setting.
