IMPORTANT SAFETY INSTRUCTIONS
RISK OF BURNS

Propane Convection Heater Manual 5
Hazard Potential Consequence Prevention
IMPORTANT SAFETY INSTRUCTIONS
RISK TO BREATHING Serious injury or death could
occur from failure to provide
proper ventilation according to
this manual..
This is a direct-red heater. It
is primarily intended for use for
temporary heating of buildings
under construction,alteration or
repair. Direct-red means that
all of the combustion products
of the heater enter the heated
space. This appliance does pro-
duce small amounts of carbon
monoxide. Carbon monoxide is
toxic. Humans can tolerate small
amounts of carbon monoxide,
and precautions should be taken
to provide proper ventilation..
Early signs of carbon monox-
ide poisoning resemble the u.
Symptoms of improper ventila-
tion are: * headache * dizziness
* burning of the nose and eyes *
nausea * dry mouth * sore throat
Use this heater only in well ven-
tilated areas! Provide at least a
three square foot (2,800 sq cm)
opening of outside air for every
100,000 BTU/hr of heater rating.
People with breathing problems
should consult a physician before
using the heater.
Carbon Monoxide Poisoning:
Early signs of carbon monox-
ide poisoning resemble u-like
symptoms such as headaches,
dizziness, and/or nausea. If you
have these symptoms, your heat-
er may not be working properly.
Get fresh air at once! Have the
heater serviced. Some people are
more affected by carbon mon-
oxide than others. These include
pregnant women, those with
heart or lung problems,anemia,
or those under the inuence of
alcohol, or at high altitudes.
Never use this heater in living or
sleeping areas.

WARNING: IMPROPER USE OF THIS HEATER CAN RESULT IN SERIOUS INJURY OR DEATH FROM
BURNS, FIRE, EXPLOSION, ELECTRICAL SHOCK AND /OR CARBON MONOXIDE POISONING.
This heater is designed as a construction heater in accordance with Z83.7a/CSA 2.14a-2007. Other
standards govern the use of fuel gases and heating products for specic uses. Your local authority can
advise you about these. The primary purpose of construction heaters is to provide temporary heating of
buildings under construction, alteration, or repair. Properly used, the heater provides safe economical
heating. Products of combustion are vented into the area being heated.
WARNING: NOT FOR USE WITH DUCTWORK.
WARNING: NOT FOR HOME OR RECREATIONAL VEHICLE USE. THE HOSE ASSEMBLY SHALL BE
PROTECTED FROM TRAFFIC, BUILDING MATERIAL AND CONTACT WITH HOT SURFACES
BOTH DURING USE AND WHILE IN STORAGE.
IMPORTANT: Read this User's Manual carefully and completely before attempting to operate or service this
heater. Improper use of the heater can cause serious injury or death from re, explosion and carbon monox-
ide poisoning.
Every possible circumstance that may involve a hazard cannot be anticipated. The warnings in this manual
and attached to the unit are therefore not all-inclusive. If a procedure, work method or operating technique
not specically recommended by the manufacturer is used, you must be sure it is safe for you and others.
You should also insure that equipment will not be damaged or made unsafe by the operating or maintenance
method you choose. CHECK WITH YOUR LOCAL FIRE SAFETY AUTHORITY IF YOU HAVE ANY QUES-
TIONS ABOUT APPLICATIONS. This heater is designed and approved for use as a construction heater under
ANSI Z83.7a/CSA 2.14a-2007.

THEORY OF OPERATION
Fuel Supply System Fuel is supplied under pressure from the supply to the heater by the natural gas
supply line. The regulator maintains a constant ow of fuel to the heater.
System of Ignition As the fuel is sprayed into the combustion chamber, through a supply nozzle, the
Piezo ignitor ignites the ne mixture of fuel and air.
Automatic Control System If the ame should extinguish, the Automatic Control Valve shuts down the
heater.
WARNING: REVIEW AND UNDERSTAND ALL OF THE WARNINGS IN THE SAFETY INFORMATION
SECTION OF THIS MANUAL.
NEVER LEAVE HEATER UNATTENDED WHILE BURNING OR WHILE CONNECTED TO A FUEL
SOURCE.
WARNING: DUE TO VERY HIGH SURFACE TEMPERATURES, IT IS IMPORTANT TO KEEP
CHILDREN, FURNITURE AND CLOTHING AWAY FROM THE HEATER. KEEP CONTROL AND
BURNER AREA FREE FROM DIRT AND DEBRIS.
WARNING: EXTREMELY HOT WHILE IN OPERATION. DO NOT TOUCH HEATER WHILE
OPERATING. KEEP CHILDREN, FURNITURE, CLOTHING, GASOLINE AND OTHER
FLAMMABLE LIQUIDS AND VAPORS AWAY FROM HEATER.
NOTE: Once the gas connection has been made, air may be trapped in the gas line. Before lighting the heater it will be neces-
sary to purge any air trapped in the line. Once this is done the heater will light and operate normally. Purging the gas line
will be necessary every time the gas cylinder is replaced.

Des étincelles électriques dans
le moteur et l’interrupteur de
pression peuvent être la cause
de blessures graves ou la mort
Des blessures graves peuvent
survenir si la prise ou la sortie
d’air du chauffage est obstruée
Des blessures graves, voire la
mort, peuvent survenir si le bon
carburant n’est pas utilisé ou si
le chauffage fonctionne durant
le ravitaillement.
Des blessures graves peuvent
survenir si le chauffage n’est
pas placé sur une surface
plane et s’il n’est pas maintenu
à l’écart des enfants et des
animaux.
Le fait de toucher les surfaces
de métal exposées peut causer
de graves blessure. Ces sur-
faces peuvent rester chaudes
pendant un certain temps après
l'arrêt du chauffage.
N’utiliser ce chauffage que dans
un endroit bien ventilé libre de
vapeurs inammables, de pous-
sière combustible ou de toute
autre matière combustible.
Ne jamais placer d’objets devant
la prise d’air (à l’arrière) ou la sor-
tie d’air(à l’avant). N’utiliser ja-
mais de système de canalisation
d’air à l’avant ou à l’arrière du
chauffage. Eloigner du chauffage
toutes les matières combustibles.
Ne jamais utiliser de carburants
tels que l’essence, le benzène,
les diluants de peinture ou
autres composés d’huile dans
ce chauffage. Ce chauffage est
extrêmement CHAUD lors de son
fonctionnement.
Ne jamais transporter le
chauffage avec du carburant
dans son réservoir.
L’entreposage de carburant en
gros doit être maintenu à une
distance d’un minimum de 25
pieds (7m60) des chauffages,
torches, groupes électrogènes
portables ou toutes autres
sources d’inammation. Tout
entreposage de carburant doit
être conforme aux réglementa-
tions des autorités locales, d’état
ou fédérale ayant juridiction.
Ne jamais déplacer ou manipuler
le chauffage lorsqu’il est encore
chaud.
Le chauffage peut démarrer à
tout moment s’il est équipé d’un
thermostat.
Toujours placer le chauffage sur
une surface stable et plane à
l’écart des enfants et des ani-
maux.
Ne jamais laisser aucune partie
de votre corps ou autres maté-
riaux entrer en contact avec les
surfaces de métal exposées de
votre chauffage.

RISQUE DE PROBLEME
RESPIRATOIRE
Des blessures graves, voire la
mort peuvent survenir si une
bonne ventilation n’est pas
fournie selon les consignes de
ce manuel.
Voici l'appareil de chauffage de
type direct. Le type direct signie
que tous les produits de com-
bustion entrent dans l’espace
chauffé. Ce radiateur a un taux
d’efcacité de combustion de 98
%, mais produit tout de même de
faibles quantités de monoxyde
de carbone. Le monoxyde de
carbone est toxique. Les êtres
humains peuvent tolérer de pe-
tites quantités de monoxyde de
carbone, des précautions doivent
donc être prises pour assurer une
ventilation adéquate.
Une ventilation inadéquate, en
violation des consignes gurant
dans ce manuel, peut entraîner
la mort. Les premiers symp-
tômes d’un empoisonnement au
monoxyde de carbone ressem-
blent à ceux de la grippe. Voici
les symptômes résultant d’une
ventilation inadéquate : * mal à la
tête * vertiges * nez et yeux qui
brûlent * nausée * bouche sèche
et * mal à la gorge.
Fournir une ouverture minimale
de 0,28 m² (3 pi²) pour la ventila-
tion, par 100 000 btu d’utilisation
nominale.
Les personnes avec des prob-
lèmes de respiration doivent con-
sulter un médecin avant d’utiliser
ce chauffage.
Intoxication à l’oxyde de car-
bone: Les premiers signes de
l’intoxication à l’oxyde de carbone
ressemblent aux symptômes de la
grippe tels que des maux de tête,
des étourdissements, et/ou la
nausée. Il est possible que votre
chauffage ne marche pas cor-
rectement si vous éprouvez ces
symptômes.
Obtenir de l’air frais immédi-
atement ! Faire entretenir le
chauffage. Certaines personnes
sont plus atteintes par l’oxyde
de carbone que les autres. Ceci
inclut les femmes enceintes, les
personnes avec des problèmes
de cœur ou de poumon, celles
sous l’inuence d’alcool ou en
haute altitude.
Ne jamais utiliser ce chauffage
dans les espaces d’habitation ou
dans les pièces où l’on dort.
