- Page 5 3.6 Suspended mounting: before mounting the device, it is necessary to make sure of the support’s strength. The unit is equipped with 4 MS threaded inserts on the top, to can be suspended. It is necessary to used slings or threaded rods adapted to the weight of the unit. The mounting must be perfectly aligned, as shown on the drawing here below.
- Page 6 3.7 If the heater is to be suspended, it is necessary to make sure of the support's strength. The heater is equipped with 4 - M8 threaded inserts on the top of the unit. Ensure the slings or suspension rods are suitable to take the weight of the heater model safely.
- Page 7 Electrical Connection and Control Regulation 4.1 The power supply is single-phase 230V/50Hz with a protected electrical cable (1). The section of the cable and its protection must be sized according to the number of units on the line and its length. The regulation box will be connected to the gas heaters by a pilot wire.
- Page 8 4.1 All gas heaters are equipped as standard with a pilot wire card. The control sends a signal via the pilot wire, to the units equipped with the pilot wire receptor (RFP card), which execute the operating order. 4.2 Four types of information are transmitted: 4.2.1 Heating demand 4.2.2...

- Page 15 Gas circuit All the following gas installation should be carried out by a technically qualified of competent person who must have a current Gas Care Certificate. If heater has been electrically installed make sure the unit is isolated from the main supply. 6.1 Change of gas The unit heaters are equipped with atmospheric gas torch burners, permitting the use of Natural gas G20, Natural gas G25 and Propane.

- Page 18 6.4 Gas connection First of all it is necessary to check that the device is in conformity with the type of gas distributed. For this purpose, you must refer to the indications shown on the identification plate. The gas supply must be appropriated to the power of the heater and be equipped with all the security and inspection devices required by current standards.
- Page 19 Commissioning Operating principle 7.1.1 The control box tests the break contact of the air pressure switch and turns on the smoke extractor. Its proper functioning is controlled by the differential air pressure switch. In case of lack of air, it prevents the control box from following its cycle. 7.1.2 After pre-ventilation, the ignition electrode lights up and the valve allows the gas passing through the injectors.
- Page 20 WARNING Never stop the device before the fan has totally stopped running. The lack of cooling air can cause the overheat thermostat to trip and require resetting. This can also cause damage to the heat exchanger over a long term. 9.
- Page 21 9.4 The heat exchanger can resist to a high pressure cleaner and can be cleaned with water. The upper access door allows a good angle to clean the heat exchanger. And the two lateral metal plates allow a good access to the rear of the heat exchanger bends.
