OPERATING PRECAUTIONS
This is a propane or natural gas, direct-fired, forced air
heater. It's intended use is primarily temporary heating of
buildings under construction, alteration or repair.
The hot air generator is designed for heating medium and
large ventilated premises, for which a fixed heating system is
required.
Heater is to be run on heating with natural gas or LPG
according to gas supply pressures that must be in conformity
with the national laws.
Heater is supplied after a complete functional test and it's
therefore prearranged for one of the working gas indicated
in SPECIFICATION: an adhesive label applied on the gas
selector valve (a) indicates the selected gas.
To change the type of gas, follow the detailed instructions
indicated in section "CHANGING TYPE OF GAS".
The heater is of the direct combustion type. The air is heated
by the energy developed during combustion and then
conveyed to the environment to be heated together with the
combustion products, thus making available 100% of the
thermal power produced. The environment must be suitably
ventilated in order to ensure adequate air circulation.
In the event of serious malfunction various safety devices
(electronic flame control unit, overheating thermostat, air
pressure switch) trigger turning off the heater .
The electronic flame control unit monitors if the flame is
irregular or goes out, the safety thermostat triggers when
the temperature in the combustion chamber exceeds the
safety limit value, the air pressure switch will cut in if the
airflow is insufficient.
In each of the said cases the unit stops according to the
procedure described in "OPERATING INSTRUCTIONS".
In each of the said cases the lamp (8) will light up and the
heater will stop working. The heater can be restarted only
by pressing the reset button (8). Nonetheless, the cause
that triggered the safety device should always be carefully
analyzed and resolved before restarting the generator (cfr.
"FAULTS, CAUSES AND REMEDIES").

SAFETY PRECAUTIONS
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 fuel types for which the heater has been
certified.
4.
Minimum clearances from combustible material must be:
1 m (3 feet) from side, ceiling, floor and rear (air inlet) of
heater 3 m (10 feet) on air outlet of heater.
5.
Heater shall not be directed toward any propane-gas
container within 6 m (20 feet) and minimum clearances
from gas cylinder must be 3 m (10 feet)
6.
Don't install the heater in places where there may be a
risk of fire or explosion
7.
All fire prevention regulations must be adhered to.
8.
The heater is not duct able and shall not be connected to
any duct work for air distribution.
9.
The room or building which is being heated must be
sufficiently ventilated so that the heater has enough air to
function properly;
10. The air suction and/or supply pipes are not blocked in any
way, there are not sheets or covers resting on the machine
or walls and bulky objects near the heater;
1 1. The generator is placed near a power switchboard having
specifications in conformity with those declared;
12. The unit is placed in a fixed position;
13. The generator is regularly monitored during operation and
checked before being started up;
14. Don't let animals or children near the heater.
15. Make sure heater is inspected before each use, and at
least annually by a qualified service person.
16. After use make sure the disconnecting switch is off.
17. When using any type of heater it is obligatory: not to
exceed the maximum level of heat output of the furnace
("SPECIFICATION TABLE");
18. 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 thermostat will turn the burner off
19. Use only the electrical power specified. The electrical
connection and grounding must comply with National
Electrical Code - ANSI/NFPA 70 (USA) and CSA C22.1
Canadian Electrical Code, Part 1 (Canada).
20. Use only in accordance with local codes or, in the absence
of local codes, with the Standard for the Storage and
Handling of Liquefied Petroleum Gases ANSI/NFPA 54 and
CSA B149.1, Natural Gas and Propane Installation Code.
