tainer 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
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)

ELECTRICAL CONNECTIONS
WARNING
Every heater is equipped with all the required
safety and control devices already factory installed. Do not
remove or disable them. Doing so could result in property
damage, injury or even death.
Every heater is supplied with the safety and control devices which
are indispensable to the correct functioning of the unit being
already electrically connected.

electrically grounded in accordance with local codes, or in
the absence of local codes, with the National Electrical Code,
ANSI/NFPA 70, and/or the CSA C22.1, Canadian Electrical
Code, if an external electrical source is utilized.
Indirect Fired Construction Heater
The following operations must now be carried out:
• P lug in the power cord having read the rating plate that specify
electric supply characteristics.
• C onnect 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
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.
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. 3: the gas pipe, the
interception tap and the anti-vibration joint are not supplied with
the heater and they must be arranged by the person in charge of
installation.
1 Main gas pipe
2 Manual shut-off valve
In case of connection of heater to 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 Installation Code, CSAB149.1.
In case of connection to a propane supply cylinder:
(a) The installation must conform with local codes or, in the
