The vacuum circuit breaker safety (<strong>USA</strong>) is used in rooms where aroom sealed combustion and ventilation system can be operatedsimultaneously and shutdown due to an external fault (eg responseto a vacuum monitoring is required to the appliance).The <strong>USA</strong> is used to monitor a minimum pressure differencebetween the room where the fireplace and the exhaust pipe to ensureadequate combustion air supply and the safe transfer of theflue gases. Falls below a minimum pressure difference in theventilation system (at least the exhaust air fan) will switch the fanoff.The <strong>USA</strong> can work with all air-ventilated manually fed furnacesaccording to DIN EN 12815, DIN EN 13229 and DIN EN 13240.The design of the stove installation is done without consideration ofthe ventilation system of the Installation room. This ensures thatthe air supply to the combustion process by switching off theventilation is guaranteed by <strong>USA</strong>.For systems that are monitored by the <strong>USA</strong>, multiple usage of thechimney is not allowed!Note the maximum temperature stresses (see technical details).This manual, especially the entries in the chapter 'Setting the <strong>USA</strong>'are from operators preserved and passed on request to the BSM<strong>Brunner</strong> <strong>USA</strong> Installation & Operation Manual 6August 2013
MOUNTING OF THE <strong>USA</strong>Important note!The <strong>USA</strong> should be mounted inthe same room as the applianceto be monitored. Location of thefireplace means the place fromwhich the fireplace gets the airrequired for combustion.The pressure gauge linebetween electronics of the <strong>USA</strong>and heating and exhaust pipemust not be kinked or laid with ahanging loop. The length of thepressure measuring line mustnot exceed 10 m. The function ofthe <strong>USA</strong> would no longer beguaranteed.Observe installation of the <strong>USA</strong>in the wall box and ensure thatthe silicone hose is not kinked orcrushed for connecting thepressure gauge line. Thefunction of the <strong>USA</strong> would nolonger be guaranteed.<strong>Brunner</strong> <strong>USA</strong> Installation & Operation Manual 7August 2013
Do not blow into the port ofthe pressure measuringline!The pressure compensationopening can be closed.Do not paint over!Do not wall paper over!Before plastering, the flushmountingbox of the <strong>USA</strong> mustbe removed from the wall box!In order to avoid subsequentdamage to the electronics, theinstallation of the <strong>USA</strong> must becarefully planned and executed.Figure 3: Pressure equalizationport (X) on top of the <strong>USA</strong>To do this, note the followingpoints:Tip: Set the flush box withscrewed plastic lid. This willensure distortion-freeinstallation.- Avoid any contact with theelectronic components, as staticelectricity can damage thesecomponents.- Construction moisture damageelectronic components.<strong>Brunner</strong> <strong>USA</strong> Installation & Operation Manual 8August 2013
• If possible do not install the <strong>USA</strong> in an external wall, to avoiddew point corrosion to the electronics.• Do not install the <strong>USA</strong> in the heated tile cladding.• The mounting shall be such that does not exceed +50 ° C and+10 ° C are not exceeded and the device is not exposed to directheat radiation.• The degree of protection IP 40 is ensured.StructureThe electronics of the <strong>USA</strong> should (observe permissible ambienttemperatures!) be near the hearth place.An ideal position is slightly above the exhaust sensor port, becauseyou can then ensures that any condensate in the pressure gaugeline runs back to the exhaust gas sensor connection (see alsoFigure: Laying the pressure gauge line).The exhaust gas sensor circuit is to be mounted at a locationwhere the ambient temperature of 180 ° C and the coretemperature of the flue gas does not exceed 500 ° C.This is usually guaranteed in the flue gas at a distance between 70cm and 150 cm from the hearth. Of the pressure measuring pointof the fireplace must not exceed 150 cm. They can be connectedto pipes with diameters from 150 mm to 250 mm.<strong>Brunner</strong> <strong>USA</strong> Installation & Operation Manual 9August 2013
Drill two 7mm holes in the fluepipe 20mm apart.Install the clamp bracket (6)around the flue. Ensure that theholes in the clamp line up withthe drilled holes.Insert the temperature sensor(2) and the connecting pipe forthe pressure measuring line(4).The temperature sensor shouldbe inserted so that the min. 75mm is in the exhaust stream.Now put the steel strip (7) intothe slot of the first bolt andsecure it with about two turns ofthe screw. Tighten the nut.Figure 4: Exhaust gas sensor connectionThe cut the steel strip so that about 3-5 cm is on left.Now, the exhaust gas sensor connection can be secured bytightening the screw.Lead the sensor cable and the pressure gauge line in a conduit to<strong>USA</strong> and connect.Ensure that the pressure gauge line does not kink or crush.<strong>Brunner</strong> <strong>USA</strong> Installation & Operation Manual 10August 2013
Connect the pressure gauge lineto the exhaust sensor connectionwith a ‘lug clamp’. Installation isas shown on the image.The pressure measuring line isconnected to the adapter in thedelivery of the silicone tube ofthe <strong>USA</strong>. The pressure gaugeline with an 'lug clamp'.Note that the ’lug clamp’ (5)cannot be opened withoutdamage.

FUNCTION TEST AND MAINTENANCEWhen the <strong>USA</strong> responded:<strong>USA</strong> constantly monitors the temperature of the flue pipe, theoperating status is indicated by the green LED. If the temperaturerises above 50 ° C (default), a burn is detected, the green LEDstarts to flash, from here the vacuum of the chimney is monitored.In order to ensure a safe exit of flue gases a comparison betweenthe room and the flue must be made, there must be a vacuum ofat least 4 Pascal.An exhaust hood or a controlled living space ventilation canproduce much higher vacuum, the subsequent flow of air isprevented by the modern, tight construction. To prevent backflow ofexhaust gas into the room, <strong>USA</strong> must stop the fan, in this case:the red LED will light and the ventilation system will be switchedoff.Function test:To test the function of the <strong>USA</strong>, connect the power and the vacuumsensor (green LED illuminated).The temperature sensor must reach approximately 50°C (greenLED flashes) (value in delivery state).Hold the vacuum hose into the room (do not connect to thechimney and not blow into it). Within about 30 seconds, the <strong>USA</strong>should shutdown (red LED lights).<strong>Brunner</strong> <strong>USA</strong> Installation & Operation Manual 21August 2013
The vacuum circuit breaker safety (<strong>USA</strong>) is in compliance with thebasic maintenance measures in accordance with DIN 31 051 inconjunction. DIN EN 13 306 to maintain operation by a specialist.The home owner must test the <strong>USA</strong> at least once a month.Turn off the power to the <strong>USA</strong> ( the ventilation system / hood willstop working ), when the power is turned on again the <strong>USA</strong> willreturn to normal start up.Check the pressure compensation opening / s for blockage andclean if necessary.Check the screws of the mounting of the sensor and retighten ifnecessary.Check the pressure gauge line for blockage and clean if necessary.Check the correct position of the clamp and seal the flue andcorrect if necessary.Contaminants in the flue delay the response time of thetemperature sensor!<strong>Brunner</strong> <strong>USA</strong> Installation & Operation Manual 22August 2013
