We cannot foresee every use which may be made
of our heaters. Check with your local fire safety
authority if you have questions about heater use.
Other standards govern the use of fuel gases and
heat producing products for specific uses. Your
local authorities can advise you about these.
Carbon Monoxide Poisoning: Direct-Fired means
that all of the combustion products enter the heated
space. Even though this heater operates very close
to 100 percent combustion efficiency, it still pro-
duces small amounts of carbon monoxide. Some
people are more affected by carbon monoxide than
others. Early signs of carbon monoxide poisoning
resemble the flu, with headaches, dizziness, and/or
nausea. If you have these signs, the heater may not
be working properly. Get fresh air at once! Check
for proper ventilation and have heater serviced.
Propane Gas: Propane gas is odorless. An odor-
making agent is added to propane gas. The odor
helps you detect a propane gas leak. However, the
odor added to propane gas can fade. Propane gas
may be present even though no odor exists.
This is a propane, direct-fired heater. Propane is
heavier than air. If propane leaks from a connection
or fitting, it sinks to the floor, collecting there with
the surrounding air, forming a potentially explosive
mixture. Obviously, propane leaks should be avoided,
so set up the propane supply with utmost care. Read
Propane/LP Safety, page 4 for additional informa-
tion about detecting propane leaks. Leak check new
connections or reconnections with a soap and water
solution and follow all connection instructions herein.
Also, ask your propane dealer for advice on the
propane application and supply installation and ask
them to check it if there are any questions.
When the heater is to be operated in the presence of
other people the user is responsible for properly ac-
quainting those present with the safety precautions
and instructions, and of the hazards involved.
Make certain you read and understand all warn-
ings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.
1. Check the heater thoroughly for damage. DO
NOT operate a damaged heater.
2. DO NOT modify the heater or operate a heater
which has been modified from its original
condition.
3. Use only propane/LP gas.
SAFETY INFORMATION
Continued
4. Use only VAPOR WITHDRAWAL propane
supply. The propane cylinder must be arranged
for vapor-withdrawal, in accordance with the
Compress Gas Associations, Small Propane
Bottle Assembly. If there is any question about
vapor withdrawal, ask your propane dealer.
5. Never use the heater if the ballast weight is
not assembled onto the base. The base must
be weighted to avoid tipping.
6. Use only the factory preset regulator provided
with the heater. Use only replacement pressure
regulators specified in this manual.
7. If used, inspect the hose before each use of
the heater. If it is evident there is excessive
abrasion or wear, or the hose is cut, it must
be replaced prior to the heater being put into
operation. Use replacement hose assembly kit
100427-01 (see Accessories, page 11).
8. This heater is for OUTDOOR USE ONLY,
even so, make sure that there is ample fresh air
ventilation. Do not use in buildings, garages
or other enclosed spaces.
9. If at any time gas odor is detected, IMMEDI-
ATELY DISCONTINUE operation until the
source of gas has been located and corrected.
Read Propane Safety, page 4 for additional
information about detecting propane leaks.
10. Install the heater such that it is not directly
exposed to water spray, rain and/or dripping
water.
11. Maintain minimum clearance to people or
normal combustible material (like paper) of
3.6 ft. (1100 mm) from top and 2 ft. (609 mm)
from the reflector.
12. Operate only on a stable, level surface.
13. Do not spray aerosols near the heater during
use or shortly thereafter.
14. Do not clean heater with combustible or cor-
rosive cleaners. Use warm, soapy water.
15. Check control compartment burners and cir-
culation air passageways for free air passage,
make sure that there are no obstructions. These
areas are a common location for spider webs,
which can present a dangerous condition,
damage the heater and render it unsafe for
use. The heater must be checked if any of the
following conditions exist:
a) Gas smell along with predominate yellow
tipping of the burner.
b) Heater does not reach temperature.
c) Uneven burner glow.
d) Burner makes popping noises during nor-
mal use, other than during shutdown.

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and circu-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a
qualified service person.
CAUTION: You must check
and keep burner/venturi tubes
clean of insect and insect nest. A
clogged tube can lead to a fire.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or small,
soft bristled brush to clean.
BURNER PILOT AIR INLET
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides a
clean burning flame. Keep these holes clear of dust,
dirt, and lint. Clean these air inlet holes prior to
each heating season. Blocked air holes will create
soot. We recommend that you clean the unit every
three months during operation and have heater
inspected yearly by a qualified service person.
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust and
dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. Your local
computer store, hardware store, or home center
may carry compressed air in a can. You can use a
vacuum cleaner in the blow position. If using com-
pressed air in a can, please follow the directions on
the can. If you don't follow directions on the can,
you could damage the pilot assembly.
Always keep the heater area clear and free from
combustible materials, gasoline and other flam-
mable vapors and liquids.
Keep the vent areas (slots in the bottom and the top
at the front of heater) clear at all times.
Visually inspect the pilot flame and burner peri-
odically during use. The burner should be bright
orange without a noticeable flame. If the burner
has a noticeable flame, cleaning may be required.
Use the following procedure to inspect burner
assembly.
It is necessary to periodically check the burner
orifice and burner venturi tube to make sure they
are clear of insects, nests or spider webs that may
accumulate over time. A clogged tube can lead
to a fire.
1. Allow heater to thoroughly cool before per-
forming any maintenance.
2. Turn control knob to the OFF position and re-
move disposable 1 lb. cylinder from heater.
3. Remove four screws securing burner assembly
to base assembly (see Figure 3, page 5).
4. Remove burner assembly from base assembly.
5. Inspect interior of burner assembly for ac-
cumulation of dust, lint or spider webs. If
necessary, clean interior with a vacuum
cleaner or apply air pressure. Do not damage
any components within burner assembly when
you are cleaning.
6. Inspect and clean main burner orifice by us-
ing a vacuum or apply air pressure at orifice
opening.
7. Inspect and clean pilot (mounted to bracket) by
using a vacuum or apply air pressure through
the air holes in the pilot (see Figure 4).
WARNING: Never use nee-
dles, wires, or similar cylindrical
objects to clean the pilot to avoid
damaging the calibrated ruby
that controls the gas flow.

No podemos prever todos los usos que se le pueden
dar a nuestros calentadores. Verifique con la autoridad
local de seguridad contra incendios si tiene preguntas
acerca del uso de calentadores.
Otras normas rigen el uso de gases combustibles y
productos que producen calor para usos específicos. Las
autoridades locales pueden informarle acerca de éstas.
Intoxicación con monóxido de carbono: de “caldeo
directo” significa que todos los productos de com-
bustión entran al espacio que se está calentando. Aun
cuando este calentador opera con una eficiencia de
combustión muy cercana al 100%, produce cantida-
des pequeñas de monóxido de carbono. El monóxido
de carbono afecta más a algunas personas que a otras.
Los primeros signos de intoxicación con monóxido
de carbono se asemejan a los de la gripe, con dolor
de cabeza, mareo y/o náusea. Si usted presenta
estos síntomas, es posible que el calentador no esté
funcionando correctamente. ¡Respire aire fresco
inmediatamente! Compruebe que haya ventilación
adecuada y haga que reparen el calentador.
Gas propano: El gas propano es inodoro. Al gas
propano se le agrega un agente oloroso. El olor
le ayuda a detectar las fugas de gas propano. Sin
embargo, el olor que se añade al gas propano puede
desvanecerse. Es posible que haya gas propano
presente aunque no haya ningún olor.
Este es un calentador de propano de caldeo directo.
El propano es más pesado que el aire. Si hay una
fuga de propano en una de las conexiones o niples,
éste fluirá hacia el piso y se acumulará ahí con el
aire circundante, lo que formará una mezcla que es
potencialmente explosiva. Obviamente, las fugas de
propano se deben evitar, por lo que debe instalar el
suministro de propano con el mayor cuidado posible.
Lea Seguridad con propano o gas LP en la página 5
para obtener información adicional sobre cómo detec-
tar fugas de propano. Revise las nuevas conexiones
en busca de fugas utilizando una solución de agua
y jabón y siga todas las instrucciones de conexión
contenidas en este manual. Además, pida consejo a
su distribuidor de gas propano sobre la instalación del
suministro y aplicación de propano y pida también
que la revise en caso que haya alguna duda.
Si el calentador se va a hacer funcionar en presencia
de otras personas, es responsabilidad del usuario
hacer que dichas personas se familiaricen con las
precauciones e instrucciones de seguridad, así como
con los peligros asociados.
Asegúrese de leer y comprender todas las advertencias.
Conserve este manual para consulta. Es su guía para la
operación segura y correcta de este calentador.
INFORMACIÓN DE

15. Revise que en los quemadores y ductos de aire
de ventilación pueda fluir libremente el aire y
que estén libres de obstrucciones. En estas áreas
comúnmente se acumulan telarañas que pueden
producir condiciones de peligro, dañar el calen-
tador y causar que sea inseguro operarlo. Debe
de revisar el calentador si se presenta cualquiera
de las siguientes condiciones:
a) Olor a gas, aunado a un coloramiento predo-
minantemente amarillo en las puntas de las
llamas del quemador.
b) El calentador no alcanza la temperatura.
c) El brillo en el quemador no es uniforme.
d) Se escuchan chasquidos del quemador durante
uso normal, aparte de cuando se apaga.
16. Use solamente agua jabonosa (1 parte de de-
tergente líquido para platos y 3 partes de agua)
para revisar que no haya fugas cada vez que se
conecta un cilindro de propano. Las burbujas
indican una fuga.
17. No ajuste el regulador de gas. Si no está seguro
del tipo de gas o de la presión de su aparato,
llame a una persona de servicio calificada.
18. Ponga la perilla de control en la posición de “APA-
GADO” cuando no esté usando el calentador.
19. Siempre desconecte el suministro de gas cuando
