Usually a thermocouple or similar device is employed to allow fuel to flow once the unit sees that there is sufficient heat to ignite the fuel. Otherwise it can be a fuel valve that "sees" an unusual flow of gas which sets off the safety.

Brivis buffalo 85 main burner not coming on pilot light is on fan comes on ???


If the pilot is on the thermo couple is ok. Could possibly be a faulty temperature limiting switch, it may be stuck and just needs a spray of WD40 or similar product. Then again I could be completely wrong.

Brivis Buffalo 15 not blowing air.


This sounds like a flame proving fault, so what's more than likely happening is the unit isn't sensing the flame. You'll see a small metal rod sticking down infront of the burner on the opposite side as the ignition source. Remove that rod, and clean it with some scotch bright. If you know how to work a volt meter you can test this part. Take the wire off the flame rod, place your meter leads in series with the wire and flame rod and set it to micro amps DC. Fire the unit up, and when your main burner lights you'll want to see a minimum of 1micro amp DC. If you're getting a higher reading than that and it still cycles I'd be suspicious of the grounding of the burner, or the ignition control! Good luck, let me know if you need any more instruction!

When main gas valve opens to start burners the gas pauses then ignites with a high volume woof.The pilot flame looks a little small could this be the issue. This unit is Brivis Buffalo year 1988 model...


The problem is called "Delayed Ignition". This can be caused by burner & pilot obstructions (dust, lint and/or pet hair) and needs to be thoroughly cleaned. At 23 years old, I'm surprised the unit is still in service.

Hope this helped you to troubleshoot and solve the problem.

Pilot lights up but would not fire up into heating, I have brivis buffalo 85


This is the proper cycle of a furnace and what should happen.

Inducer motor kicks on, it runs for a little bit, about 3-5 seconds, then you should see a bright yellow glow, this is the igniter, shortly after, you should hear a click and the gas should start to flow, almost immediately it turns to a blue flame. Then your igniter should turn off and the blower motor start up.

If the pilot turns on and the gas ignites, then shortly after the unit shuts off, chances are this is your blower motor. It is not starting up, then the heat limit is reached in your unit and the safety shuts it off.

Burners on our Brivis Buffalo 52 Ducted heater aren't getting gas


test thermosat for proper operation ie-broken wire-power if good jump stat and check if unit goes on if it does than stat internal problem or wiring problem and needs replacement or repair --if stat good check fan safety/high limit sensor if good would need to check and test thermocouple thats the tube that the pilot flame burns on may be enough to keep pilot burning but not enough to open valve for heat demand

Hi. Brivis Buffalo not igniting


Okay,

first and for most do not light burners manually, if that chamber is filling up with gas and you light that sucker you risk the chance of causing an explosion or a blow back that will burn you. What you need to address is

-are the burners clean
-is there proper gas entering the gas valve
-is there proper gas to the manifold
-is the flue product being exhausted properly
-is my exchanger sooted up
-is my gas valve working properly


pm me for walk through steps

Brivis Buffalo 85 central heating unit - fan stays on problem


I have exactly the same problem. When I have the cover off there is a red light on, from what I can tell is the "Over Heat Fan" this seems to keep the fan on, and because it is in error prevents the system igniting. Haven't got a solution yet it only happened last night. Stu.

Heating isn't working, can't find the red button to relight the pilot


Many times the knob to turn the gas on on the valve is also the pilot knob. Turn it to pilot and hold it down while you light the pilot. Hold it for up to a minute and release. If the pilot stays on then turn it to on. If not you need a new thermocouple.
