During the installation, we recommend to tighten the nut 

fastening the external gas supply pipe without exceeding the 

tightening torques shown below: 

- Ø 3/4’’: 150 Nm;

Smoke outlet features

Unit is shipped with an outlet adaptor for connection to 
exhaust pipe. If there is no exhaust pipe used, a terminal 
feature located on the accessories should be installed.

Note: Exhaust pipe material has to be chosen carefully 
to avoid corrosion.

General Electrical Recommendations

Electrical Parts

When reviewing this manual keep in mind.
- All field-installed wiring must be in accordance with 
local regulations, CE directives and guidelines. Be sure 
to satisfy proper equipment grounding requirements 
according CE
-  The following standardized values - Maximum Amps - 

Short Circuit Amps - Starting Amps are displayed on 
unit nameplate.

-  All field-installed wiring must be checked for proper 

terminations, and for possible shorts or grounds.

Note:

 always refer to wiring diagrams shipped with unit 

or unit submittal for specific electrical schematic and 
connection information.

WARNING Hazardous Voltage!

Disconnect all electric power, including remote 
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be 
inadvertently energized. Failure to disconnect power 
before servicing could result in death or serious injury.

Important!

Do not allow conduit to interfere with other 
components, structural members or equipment. Control 
voltage (230 V) wiring in conduit must be separate from 
conduit carrying low voltage (<30V) wiring. To prevent 
control malfunctions, do not run low voltage wiring 
(<30V) in conduit with conductors carrying more than 30 
volts.

CAUTION! 

Inverters are equipped with integrated filters. 
They are not compatible with insulated neutral load 
earthing arrangements.

WARNING! Hazardous Voltage with Capacitor!

Disconnect all electric power, including remote
disconnects and discharge all motor start/run and
AFD (Adaptive Frequency TM Drive) capacitors before
servicing. Follow proper lockout/tagout procedures to
ensure the power cannot be inadvertently energized. 
Any contact with electric components, even after the 
unit has been switched off, can cause serious injury or 
death. Wait at least 5 minutes after switching off the 
unit, until the current dissipates.
• 

For variable frequency drives or other energy 
storing components provided by Trane or others, 
refer to the appropriate manufacturer’s literature for 
allowable waiting periods for discharges capacitors. 
Verify with an appropriate voltmeter that all 
capacitors have discharged.

• 

DC bus capacitors retain hazardous voltages 
after input power has been disconnected. Follow 
proper lockout/ tagout procedures to ensure the 
power cannot be inadvertently energized After 
disconnecting input power, wait five (5) minutes 
for units which are equipped with EC fans and wait 
twenty (20) minutes for units which are equipped 
with variable frequency drive (0V DC) before 
touching any internal components. Failure to follow 
these instructions could result death or serious 
injury.

Installer-Supplied Components

Customer wiring interface connections are shown in the 
electrical schematics and connection diagrams that are 
shipped with the unit. The installer must provide the 
following components if not ordered ith the unit:
•   Power supply wiring (in conduit) for all field-wired 

connections.

•   All control (interconnecting) wiring (in conduit) for 

field supplied devices.

•   Circuit  breakers.

Installation

If pressure is higher than 60mbar, a presure reducer must 
be installed at a distance of at least 10m and no pressure 
stabiliser must be fitted between the pressure reducer and 
the heater, but leaving the gas filter.

10m

Max 60 mbar
