damages to goods or persons due to improper use of units.
GENERAL RECOMMENDATIONS
This indirect-red heater runs on natural gas or L.P.G. and is
fitted with a flue to take the fumes away through the chimney.
Prior to shipping, the heater is configured for either natural gas
or LP, labeled on the gas selector valve for the correct fuel type
and given a complete functional test. To change the type of gas,
follow the detailed instructions indicated in section “CHANGING
TYPE OF GAS”.
Always follow local ordinances and codes when using this
heater:
• Read and follow this owner’s manual before using the
heater.
• Use only in places free of ammable vapors or high dust
content.
• Never use heater in immediate proximity of ammable
materials (the minimum distance must be 6 ft.).
• Make sure re ghting equipment is readily available.
• Make sure sufcient fresh outside air is provided according
to the heater requirements. Direct combustion heaters
should only be used in well vented areas in order to avoid
carbon monoxide poisoning.
• The heater is installed near a chimney to take away the
fumes (see “Ventilation” on page 5) and connected to an
electrical switchboard.
• When the heater is connected to a ue pipe, the ue pipe
shall terminate in a vertical section at least 3 feet long and
sufficient draft shall be created to assure safe and proper
operation of the heater.
• Never block air inlet (rear) or air outlet (front).
• In case of very low temperatures add kerosene to the
heating oil.
• Make sure heater is always under surveillance and keep
children and animals away from it;
• Before starting the heater always check free rotation of
ventilator fan.
• Indirect red units only can be connected to air ducts to
distribute warm air, with respect to the max. static pressure
declared (see “TECHNICAL SPECIFICATION” sheet).
• Unplug heater when not in use.

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 dimen-
sioned according to the gas flow in Tab.1
• The cylinder supply system shall be arranged to provide for
vapor 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 disconnected and the cylinders) removed from the heater
and stored in accordance with Standard for the Storage and
Handling of Liqueed Petroleum Gases, ANSI/NFPA 58 and
CSA B149.1, Natural Gas and Propane Installation Code.
GAS LINE CONNECTIONS
The connection to the gas feed pipe, whose sizes must correspond to the kind of system to be made, must be carried out by
placing the “gas ramp” as indicated in Fig. 2: the gas pipe (1), the
interception tap (2) and the anti-vibration joint (3) are not sup-
plied with the heater and they must be arranged by the person in
charge of installation.
Fig. 2
STARTUP
The heater is supplied after a complete functional test and it’s
therefore prearranged for one of the gas (natural or L.P.G.) indicated in Tab. I: an adhesive label applied on the gas selector valve
(13) indicates the working gas (usually it’s natural gas). Should it
necessary to change the kind of gas (from natural gas to L.P.G
or vice-versa) follow the detailed instructions indicated in section
“CHANGING TYPE OF GAS”.
Only when the heater has been prearranged according to the
proper working gas it will be possible to carry out the following
operations:
• Leak away some gas from the feed pipe;
• Check that the pipe is gas proof;
• Open the gas stopcock and start the hot air generator;
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 already electrically connected.
WARNING Electrical grounding shall be in compliance
with the National 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 current than the maximum permitted limit.
CHANGING TYPE OF GAS
This operation may be carried out several times during the working life of the machine and not only at initial startup. Therefore,
first of all check the adhesive label attached to the gas selector
valve (13) in Fig. (1) to establish the original category of the gas
and then consult Tab. I to identify the supply pressure, the working pressure, the using conditions of manual valve.
To change kind of gas it is necessary (Fig. 3):
• to remove the sticker on the gas selector valve stating the
gas used at that time,
• to remove the screw under the sticker and turn the manual
handle on the correct side according to the condition described in Tab.I and by following instruction:
Fig. 3
• After having moved the handle into the opposite position,
put again the fixing screw and a new sticker on it, stating
the gas which has to be used (a number of different stickers
are supplied with the machine)
