tional Fuel Gas Code ANSI Z223.1/NFPA 54 and the Natural Gas 
and Propane Installation Code, CSA B149.1.” 

When equipped for propane 
•  The installation must conform with local codes or, in the ab-

sence 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 con-

tainer 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.

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 be-
ing 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. 

gas line cOnnectiOns 

The connection to the gas feed pipe, whose sizes must corre-
spond 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.

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.) indi-
cated 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; 

cHanging tYpe OF gas 

This operation may be carried out several times during the work-
ing 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 work-
ing 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 de-
scribed 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)
