DESCRIPTION
JUMBO space heaters have been designed for use in small to
medium-sized rooms and buildings where a fixed or mobile heating
system is required.
Heat is produced by combustion and the heat from the smoke is
transmitted to the fresh air through the metal walls of the combustion
chamber and the heat exchanger. The combustion chamber is of the
type where smoke circulates twice.
The air and smoke pass through separated ducts, both of which
are welded and sealed. When, after combustion, the waste gases have
cooled, they are expelled through a duct which must be connected to a
chimney or chimney flue. The chimney or chimney flue must be big
enough to guarantee that the smoke is expelled efficiently.
The air which is used in combustion is aspirated directly from the
room or building which is being heated. It is therefore of utmost im-
portance that the room or building be properly ventilated so that
enough fresh air is circulating at all times.
The air outlet can be replaced by outlet panels with two or four
openings, all of which must be kept open.
Jumbo heaters can operate with burners that are fuelled by diesel oil
#2 max., natural gas or propane.
Warning
Only the burners which are chosen and supplied by the
manufacturer can be used. If another type of burner is
used the heater no longer complies with CSA / UL regula-
tions.
Applied burners are listed in the final "TECHNICAL CHAR-
ACTERISTICS" sheet
There are three safety devices which are activated in case of seri-
ous malfunction. The Burner Control Device, which is mounted on the
burner and has a restart button, automatically stops the burner if the
flame goes out. The Overhrat Thermostat, L2, of the manuel restart
type, is activated if the temperature of the combustion chamber rises
above the set maximum limit; the warning light (9) lights up and the
heater stops working. The Thermal Relay,RM, is activated if the fan
motor starts to use more electrical current than the maximum permit-
ted limit; the warning light (10) lights up and the heater stops working.
If any of these safety devices are activated you should check care-
fully what the problem actually is before pressing the restart button
and starting the heater off again ("OBSERVED FAULTS, CAUSES AND
REMEDIES").
Overheat safety thermostat, L1, shuts down the heater if air flow is
not sufficient to cool off combustion chamber: the heater will restart
automatically as soon as the heater has cooled down enough (The
lamp (9) lights up and then it cuts down).
GENERAL ADVICES
The heater is designed and approved for use as a construction
heater in accordance with Standard ANSI Z83.7 - CGA 2.14.
Intended use is the temporary heating of buildings or structures
under construction, alteration or repair.
Warning
Check with your local fire safety authority if you have
questions about applications.
Here are a few general guidelines which should be followed:
• Follow the instructions in this booklet very carefully.
• Don't install the heater in places where there may be a risk of fire
or explosion.
• Inflammable material should be kept at a safe distance from the
heater (Minimum 6 feet).
• All fire prevention regulations must be adhered to.
• The room or building which is being heated must be sufficiently
ventilated so that the heater has enough air to function properly.
• The heater must be near a chimney or chimney flue and a suit-
able electric switchboard.
• Don't let animals or children near the heater.
• Make sure heater is inspected before each use, and at least an-
nually bya qualified service person.
• After use make sure the disconnecting switch is off.
When using any type of space heater it is obligatory:
• not to exceed the maximum level of heat output of the furnace
("TECHNICAL SPECIFICATION TABLE");
• to make sure that there is adequate air circulation and air supply
to the heater and that nothing is obstructing the aspiration and
expulsion of air; movement of air may be obstructed in various
ways including placing covers or other objects on the heater or
positioning the heater too near a wall or other large object. If the
airflow is not adequate, the combustion chamber will overheat
and the overheat safety thermostat L1 will turn the burner off
and on continnously ("OBSERVED FAULTS, CAUSES AND
REMEDIES").
INSTALLATION
Warning
The following operations must be carried out by quali-
fied personnel only.
ELECTRICAL CONNECTIONS AND SETTINGS
Every space heater is supplied along with the safety and control
devices which are indispensable to the correct functioning of the unit.
The electric switchboard, burner, the fan thermostat, overheat safety
thermostat and the overheat thermostat with manual restart have al-
ready been connected.
Warning
Power supply cord of proper dimension shall be connect-
ed to the main switchboard and heater shall be ground-
ed.
Electrical grounding shall be in compliance with the Na-
tional Electrical Code ANSI/NFPA 70 or the CSA C22.1
Canadian Electrical Code, Part I.
The following operations must now be carried out:
• Plug in the power cord having read the adhesive label which de-
tails electricity supply characteristics.
• The burner must be connected to the fuel supply (Burner In-
struction Manual).
• Connect the burner to the electricity supply with the burner plug.
• Connect accessories such as the room thermostat or clock to the
unit's electric switchboard with the thermostat plug.
Having completed all these operations check carefully that all
electrical connections correspond to the wiring diagram. When the
heater is first turned on you must check that the fan does not use more
current than the maximum permitted limit.
Finally, to regulate the burner follow the instructions in the Burner
Instruction Manual.
CONNECTION TO HOT AIR DUCTS
The space heater provides heat by releasing and dispersing hot air.
An air head is supplied with each unit but it can be replaced by other
types of head with two or four openings which allow for flexible tubes
in heat distribution. The screws which hold the original outlet in place
should be removed and the new outlet should be screwed on in place
of the old.
The new head may be connected to new air ducts if the user wish-
es to satisfy specific needs. In this case and in particular if the diame-
ter and length of the ducts have been changed or if the number of
bends has been modified, air output may vary. Consequently it is very
important to check and regulate air output when any modification is
made to air heads or air ducts. In all circumstances you must ensure
that:
• The fan motor does not absorb more current than the maximum
permitted limit;
• The volume of air flow corresponds to the recommended level.
If the heater is equipped with centrifugal fan and if the volume of
hot air differs from preset values proceed as follows (Fig. 1):
