Smells from boilers need investigation. I've never come across a boiler that smells of ammonia. Nevertheless it needs urgent attention.

Ammonia type smells invariably come from the products of combustion most notably *incomplete combustion* cause by various deficiencies eg: flame impingement, ghosting, flame lift-off, poor primary combustion air etc etc.

The onion type smell particularly is caused by the formation of aldehydes (eg: 'formaldehydes') causes watering of the eyes and is *totally dangerous* when inhaled.

In the interests of safety to yourself and others turn off the appliance immediately and call out a professional gas-safe registered tradesman before any further use.
