Question About MPI Technologies Gas Heater MPI-422
Owner manual...

We have a MPI-422 monitor heater and no owners manual. The system is acting strangely by shutting off prior to producing heat. If we keep turning it on it works eventually but then some times it keeps running, up to 10degrees higher than the level the thermostat is set for. Can you help us troubleshoot the problem? Thanks for your prompt response to this email. geoffhubbs@gmail.com
