THEORY OF
!
OPERATION
The Fuel System: The air pump forces air through the air line. The air is then
pushed through the burner head nozzle. This air causes fuel to lift 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.
The Ignition System: The electronic ignitor sends voltage to the spark plug.
The spark plug ignites the fuel and air mixture.
The Flame-Out Control System: This system causes the heater to shut down
if the flame goes out.

WARNING
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
IMPORTANT:
container is clean. Foreign matter such as rust, dirt, or water will cause the flameout control to shut down heater. Foreign matter may also require you to clean fuel
system often.

WARRANTY AND REPAIR SERVICE
DESA International warrants new Products sold by it to be
free from defects in material or workmanship for a period of 360
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
International’s option, any parts which appear to DESA International upon inspection to have been defective in material or
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 PURPOSE. IN ANY EVENT IMPLIED WARRANTIES INCLUDING 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, incidental, 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.
NO EMPLOYEE OR REPRESENTATIVE IS AUTHORIZED TO
CHANGE THIS WARRANTY IN ANY WAY OR GRANT ANY
OTHER WARRANTY UNLESS SUCH CHANGE IS MADE IN
WRITING AND SIGNED BY AN OFFICER OF DESA INTERNATIONAL AT ITS HOME OFFICE.
