The flue equipment must have been positively assessed for application with gas-fired appliances.
This positive assessment should have been issued by an inspection body with ISO 17025 accredita-
tion. We advise you to obtain supply and flue equipment from the manufacturer. This complies
with these requirements.
2.3 Gas connection
The installation of the gas pipeline and gas tap must comply with the relevant local and/or national
regulations. The gas tap must be positioned within reach of the appliance
[3] . If the connection
line is subject to pressures above 60mbar, this gas tap must be closed. In the event of any doubt
about engrained dirt, apply a gas filter. Always blow through the gas pipe in compliance with the
regulations prior to operating the appliance. If the appliance needs to be converted to a different
type of gas than the one indicated on the type plate, the supplier of the appliance must be con-
tacted. He can advise you which parts must be replaced in order for the appliance to operate cor-
rectly with the type of gas required.
2.4 Electrical connection
Installation must comply with the relevant local and/or national regulations. Ensure that there is a
correct connection set with mains fuse. The electrical diagram appears on the appliance. A basic
diagram for type GSTE can be found in chapter 7 Electrical Diagram. PLEASE NOTE: the unit is
phase-sensitive and will only operate when it has been appropriately earthed. The appliance must
be fitted with an isolator switch which interrupts phase and zero (not the earth). The isolator
switch must be accessible at all times. Never, under any circumstances, allow the supply to the
appliance to be interrupted by other switches. This could result in the appliance overheating.
2.5 Room thermostat and reset button
The room thermostat must be located at a height of approx. 1.5m and not directly within the flow
of warm air. Each appliance must be fitted with a room thermostat. If several appliances are to be
connected in one room, a pass-through box (0647080) must always be used for each appliance.
Connect the room thermostat in accordance with the electrical diagram for the appliance. If a
room thermostat has been purchased from the supplier of the appliance, the connection diagram
is included in the room thermostat manual. Incorrect connection will render the manufacturer's
warranty void. The reset button must not be located outside the visual range of the appliance.
3.0 Start-up/shutdown
3.1 General
Before being packed, each appliance is fully tested for safety and correct operation. This includes
the setting of the gas pressure, burner pressure and CO. However, always check the burner
pressure variation and the pre-pressure. Never turn set screws incorrectly. Do not forget to
instruct the user on the proper use and operation of the appliance and peripherals.
