Troubleshooting 101: Portable Heaters

December 10, 2020

Troubleshooting portable heaters can be a difficult task. Just because your portable heater won’t start up doesn’t necessarily mean it’s broken. If you are using On Site Companies’ products and you run into this issue, be sure to use this helpful guide below to test why your equipment isn’t working.

If you are renting from us and are still unable to start your portable heater after carefully following the instructions below, please contact us at 651-429-3781 to schedule an On Site Heat Technician to be dispatched immediately.

Troubleshooting Portable Heaters

Troubleshooting Portable Ground Heaters

  • Make sure there is power to the machine
  • Make sure there is fuel in the machine
  • For the E1100 – make sure to wrap fuel tank and fuel filter with extra hose and blanket to avoid fuel gelling
  • Make sure the unit is level – if not, machine may be showing a false low level fault
  • Check to make sure there is nothing laying on the lines
  • Be sure the pump is running (check flow meters – a.k.a. spinning dials) to make sure they are turning:
  • 1) If not pumping – check for low level fault light located on control panel
  • 2) If in low level fault – there may be a leak
  • Check for leaks
  • Make sure the burner is on:
  • 1) Check burner fault module located on the side door (green button and red light)
  • 2) Press and hold green button for 45 seconds to try and reset

 

Troubleshooting Standard Portable Heaters

  • Make sure the start button has been pressed
  • Be sure the heater is plugged in to a dedicated 120v / 20amp outlet
  • Check to see if the GFI/breaker has been tripped
  • Be sure the thermostat is set high enough to call for heat
  • Be sure the gas is on:
  • 1) For propane – check the valve to the tank and also the “t” valve right after the red regulator
  • 2) For natural gas – check the “t” valve right after the meter
  • If you are burning propane check to see if there is at least 20% in the tank
  • Be sure there are no materials blocking the front or back of the heater
  • Check to see if the hose is kinked or if there is anything on it such as lumber, vehicles, etc.
  • Be sure gas selector valve is in the correct position if applicable (natural gas or propane)
  • Be sure all extension cords are grounded
  • All ductwork must be straight to maintain constant air flow
