Operating buttons and other functions of the gas control block BM 733
3.1 Switching on the unit
•Open the gas shut-off cock that has been installed in the gas pipe to the unit.
•Turn the operating button (A) from “Off” (C) position right round to the right until it stops.
•Now press the button and turn to the left until the ignition position. You will now hear a click. This is a
spark ignition. You will be able to see whether the pilot is burning through the window. Click a few times if
required until the pilot lights up.
•When the pilot is burning, hold the button pressed in for another 10 seconds and then let the button come
up slowly. Now the pilot must carry on burning.
•If this is not the case then wait for one minute and repeat the procedure.
•By turning the button to the left, the main burner is ignited and the desired flame height can be set.
•In position “Pilot” (B) the main burner goes out and just the pilot remains burning.
3.2 Switching off the unit
•In order to turn off the unit completely, press the operating button (A) in “Pilot” position and turn further to
the right until it stops and then release the button.
•The pilot then goes out. We, however, recommend allowing the unit to burn with the pilot on during the pe-
riod of use.
•If the fireplace will not be used for a longer period of time, we recommend also closing the gas shut-off
cock completely in the supply line.

4. Installation instruction for flue version
General
•Only have the unit installed and connected by a recognised fitter in accordance
with the locally applicable gas installation rules and regulations.
•Never install the unit against or within a flammable wall.
•Fit the apparatus on a non flammable floor. If you fit the apparatus on a wooden
floor or floor covering, it is preferable to use a steel floor plate which is available at our warehouse.
•A chimney draught of approximately 0.5 mm water column is sufficient, measured at full load of the unit.
•We recommend reducing the draught if the chimney draught is higher than 2 mm water column.
•If a window fan has been installed in the room or if the unit is being installed in an insulated home, pressure
equalising openings to the outside air must also be installed. This is necessary to ensure that the chimney
continues to work should any underpressure occur.
•We also recommend connecting gas heaters, gas inserts and gas built-in fireplaces to an outlet vent that is
made completely of 100 mm aluminium and/or stainless steel. This will ensure that there are no problems
with regard to the thermal outlet protection and other issues.
•We also recommend using an aluminium and/or stainless steel flue lining when connecting to an existing
outlet vent in relation to a fireplace where before wood, coal or oil was burnt.
4.1 Fitting the unit
Fit the unit as tightly as possible to the flue so that a short, not corroding connection is made. Preferably without
bends. All in line with the locally applicable gas installation regulations.
The connections must be tension-free to ensure the gas regulating equipment is not damaged.
Check
Check the gas connections made to ensure that there is proper gastightness by using soapy water or a leak search
spray. Switch on the fireplace according to the operating instructions.
