DESCRIPTION
The PHOEN/N heater is designed for heating medium and large
ventilated premises, for which a fixed or mobile heating system is re-
quired.
PHOEN/N heater is to be run on heating with natural gas or L.P.G.
according to gas supply pressures that must be in conformity with the
national laws.
Gases to be used are indicated in Tab. I together with the supply
pressures, the regulation of the gas valves group (burner pressure) and
gas flow.
The PHOEN/N heater is supplied after a complete functional test
and it’s therefore prearranged for one of the working gas indicated in
Tab. I: an adhesive label applied on the gas selector valve (a) indicates
the selected gas. To change the type of gas, follow the detailed instruc-
tions indicated in section “CHANGING TYPE OF GAS”.
The PHOEN/N heater is of the indirect combustion type. The air is
heated by the energy developed during combustion and then conveyed
to the environment to be heated while a chimney takes away smokes
and combustion products.
The environment must be suitably ventilated in order to ensure
adequate air circulation.
In the event of serious malfunction various safety devices (electro-
nic 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 and the gas pressure swit-
ch (if available) will cut in if the gas supply pressure is too low. In each
of the said cases the heater will stop working: for the first two cases it
can be restarted only by pressing the reset button (8) while for the
other two it can restart automatically.
Nonetheless, the cause that triggered the safety device must be
carefully analyzed and resolved before restarting the generator (cfr.
“FAULTS, CAUSES AND REMEDIES”).

The heater is designed and approved for use as a construction
heater in accordance with Standard ANSI Z83.7 - CGA 2.14.
Other standards govern the use of fuel gases and heat producing
products in specific applications. Your local authority can advise you
about these.
Intended use is the temporary heating of buildings or structures
under construction, alteration or repair.
Installation, setting and use of the heater must be effected in accor-
dance with the applicable regulations and laws relating to machine use.
Warning
Check with your local fire safety authority if you have
questions about applications
Here are a few general guidelines which should be followed:
• The instructions in this manual are carefully followed;
• Don’t install the heater in places where there may be a risk of fire
or explosion
• Minimum clearances from combustible material must be:
1 m (3 feet) on side and air inlet of heater
1.5 m(5 feet) on top of heater
3 m (10 feet) on air outlet of heater
• 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)
• 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 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;
• The generator is placed near a power switchboard having specifi-
cations in conformity with those declared;
• The unit is placed in a fixed position;
• The generator is regularly monitored during operation and
checked before being started up;
• Don’t let animals or children near the heater.
• Make sure heater is inspected before each use, and at least an-
nually by qualified service person.
• After use make sure the disconnecting switch is off.
• Not to exceed the maximum level of heat output of the furnace
(“TECHNICAL SPECIFICATION TABLE”);
INSTALLATION INSTRUCTIONS
Warning
All the operations described in this paragraph must be
performed by professional and skilled personnel only
When equipped for Natural Gas, the installation shall conform with
local codes or, in the absence of local codes, with the National Fuel Gas
Code ANSI Z223.1/NFPA 54 and the Natural Gas and Propane Installa-
tion Code, CSA B149.1."
When equipped for propane
• .the installation must conform with local codes or, in the absence
of local codes, with the Standard for the Storage and Handling of
Liquefied Petroleum Gases, ANSI/NFPA 58 and the Natural Gas
and Propane Installation Code, CSA B149.1.
• .heater shall not be directed toward any propane-gas container
within 6 m (20 feet)
• .size and capacity of gas cylinders shall be properly dimensioned
according to the gas flow in Tab.1
• .the cylinder supply system shall be arranged to provide for va-
por withdrawal from the operating cylinder
• .after having connected to gas cylinder, open the supply tap and
check the supply pipe and fittings for gas leaks. Only use foam
soap or an approved leak detector.
• the gas shall be turned off at the propane supply cylinder(s)
when the heater is not in use.
• .when the heater is to be stored indoors, the connection between
the propane supply cylinder(s) and the heater must be discon-
nected and the cylinders) removed from the heater and stored in
accordance with Standard for the Storage and Handling of Lique-
fied Petroleum Gases, ANSI/NFPA 58 and CSA B149.1, Natural
Gas and Propane Installation Code.
Warning
Never use free flames to detect gas leaks
ELECTRICAL CONNECTIONS
Warning
The power line of the generator must feature an earth
lead and a residual current circuit breaker.
The supply cable must be connected to a switchboard
with sectioning switch.
Every heater is supplied along with the safety and control devices
which are indispensable to the correct functioning of the unit being al-
ready electrically connected.
Warning
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 rating plate that specify
electric supply characteristics.
• Connect accessories such as the room thermostat or clock to the
unit’s control panel with the thermostat receptacle.
Having completed all these operations check carefully that all elec-
trical connections correspond to the wiring diagram. When the heater
is first turned on you must check that the fan does not use more cur-
rent than the maximum permitted limit.
