THEORY OF
OPERATION
The Fuel System: The motor turns the fuel pump. The fuel pump pulls fuel from
the fuel tank. The fuel pump pushes fuel through a filter and a solenoid valve and out
the burner head nozzle. 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.
The Ignition System: The electronic ignitor sends voltage to the spark plug. The
spark plug ignites the fuel and air mixture.
The Safety Control System: This system causes the heater to shut down if the
flame goes out. It also allows the fan to continue running after normal shutdown of
heater. This cools the combustion chamber.

WARNING
WARNING ICON G 001
Use only kerosene or No. 1 fuel oil to avoid risk of fire or
explosion. Never use gasoline, naphtha, paint thinners, alcohol,
or other highly flammable fuels.
Do not use heavy fuels such as No. 2 fuel oil or No. 2 diesel. Using heavy fuels
will result in:
• clogged fuel filter and nozzle
• carbon build-up on spark plug
• the need of non-toxic anti-icer in fuel during very cold weather
VENTILATION
IMPORTANT:
container is clean. Foreign matter such as rust, dirt, or water will cause safety
control to shut down heater. Foreign matter may also require fuel system to be
cleaned frequently.
Follow the minimum fresh, outside air ventilation requirements.
If proper fresh, outside air ventilation is not provided, carbon
monoxide poisoning can occur. Provide proper fresh, outside air
ventilation before running heater.

CAUTION
WARNING ICON G 001
Never unplug heater while heater is running. Heater must go
through purge cycle. The purge cycle cools the combustion
chamber. Damage to heater can occur if combustion chamber is
not cooled. Do not restart heater until purge cycle is complete.
1. Turn thermostat dial to lowest temperature setting. This will cause heater
flame to go out. The motor will continue to run during the purge cycle. This
allows the fan to cool the combustion chamber. When the purge cycle is
finished, the motor will stop. Do not unplug heater until purge cycle is
finished.
2. Unplug extension cord from outlet.
3. To temporarily stop heater, set thermostat at a temperature lower than air
around heater. Heater will cycle back on if air temperature around heater
matches thermostat setting.

DESA International warrants new Products sold by it to be

ninety days after date of delivery to the first user and subject to
the following conditions:
DESA International's obligation and liability under this
Warranty is expressly limited to repairing or replacing at DESA

workmanship when shipped from the factory. Such parts shall
be provided at no cost to the user, at the business establishment
of any factory authorized service center or the factory during
regular working hours. The Warranty shall not apply to component parts or accessories of Products not manufactured by
DESA International and which carry the warranty of the manufacturer thereof, or to normal maintenance (such as pressure
adjustments) or to normal maintenance parts (such as filters
and spark plugs). Replacement or repair parts installed in the
Product covered by this Warranty are warranted only for the
remainder of this Warranty as if such parts were original components of said Product. DESA INTERNATIONAL MAKES NO
OTHER EXPRESS WARRANTY. TO THE EXTENT PERMITTED BY LAW DESA INTERNATIONAL MAKES NO IMPLIED
WARRANTY AND MAKES NO WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PUR-

THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE LIMITED TO THE DURATION OF
THIS EXPRESS WARRANTY.
Any transportation charges, costs of installation, duty,
taxes or any other charges whatsoever must be borne by the
user. DESA International's obligation under this limited Warranty shall not include any liability for direct, indirect, incidential,
or consequential damage or delay. If requested by DESA
International, Products or parts for which a warranty claim is
made are to be returned transportation prepaid by user to the
factory. Any improper use, including operation after discovery
of defective or worn parts, operation beyond capacity, substitution of parts not approved by DESA International, or any
alteration or repair by others in such manner as in DESA
International's judgement affects the Product materially and
adversely, shall void this Warranty.
