Question about Mr. Heater Natural Gas Garage Heater - 45,000 BTU
Posted by Anonymous on
According to the Owners/Installation Manual, the 4 flash blink code indicates that the High Limit or Roll Out Switch is open. This may be caused by a venting problem or high altitude operation. make sure you have the proper pressure to the heater's regulator. For Natural Gas it must be a continuous 7 water column inches.
For further information, I have included a link to your Owners Manual that you can download and print, for future reference. http://www.mrheater.com/upload/newsletter/MHU_HSU_CUH_60016_BL.pdf
Hope this helped to solve your problem.
