Gas heater mdl # SEP- 60A-1 becomes intermittent the colder it gets. It’ll heat to the setting on the Lux 500 thermostat at 30 +- but will not fire up regularly the colder it gets.
It’ll work for a while then not fire up on the next cycle. The only thing working on it will be the exhaust blower. It will just run on for hours. If I turn off the unit at the Lux 500 thermostat and turn it back on the exhaust fan will start up, you hear ignition spark and it will heat for a while then act up again. Help appreciated.
