Hi I am new here but have come often to learn. Having an issue maintaining a flame on baxi ht for dhw. With a tap open the unit struggles to reach 40c and the flame light flickers. Raised the output temp on a qaa73 remote but still same result. Am in hurricane sandy area trying to get people heat and need help thanks
natural gas. have not checked pressure, would that be done with a combustion analyzer? i know the gas is the issue, as the unit fires and goes off constantly on a dhw call. although for about an hour yesterday it did fire and maintain fine, then back to the same issue. i appreciate your time and knowledge in helping me.
