Check water softening equipment if lime is found in the tank. DO NOT ATTEMPT TO HEAT HARD WATER. (See maintenance label on heater.) 8. Change the magnesium anode rods every six to 12 months or when they are reduced to 3/8” diameter (see maintenance label on heater). We recommend the installer use PermaBond LH-050. Teflon tape should not be used when installing magnesium or aluminum anode rods. 9. Open the relief valve test lever to flush out the tank. Make sure it reseats itself. 10. If the heater is to be shut off in cold weather, drain the tank to prevent freezing. SERVICE 1. Check the fuel supply, electrical wiring and fuses, and make sure temperature control is calling for heat. 2. If the motor runs but there is no flame, remove the electrode assembly, clean, readjust to the burner manufacturer’s specifications, check the electrode porcelain for cracks and replace if necessary. Check the transformer to see if it is producing a strong spark. (Use extreme CAUTION: The transformer has a 10,000 volt output). Check that the coupling between the motor and pump shaft is not slipping. Check the set screw on the blower wheel for tightness. Clean or replace the nozzle with the correct size and spray angle (see Chart A, page 11). 3. Bleed the pump and check for clear, air-free oil. If the oil is milky or frothy, check the line for air leaks at fittings. Tighten all fittings again. Check the filter gaskets and make sure cartridge is clean. 4. If the burner motor does not run, check the motor thermal overload button (red button on end of motor). Reset the primary control by pushing the reset button on the control. If the burner motor still does not run after resetting the control, turn off the electricity and replace the flame detector (with the same make) located in the burner compartment. Reset the primary control. If the motor still does not run, replace the control. 5. If the burner ignites and runs a short time (30-40 seconds), then goes out on safety, replace the flame detector. If the burner still runs only a short time, replace the control. 6. If there is a smell of oil or combustion products, remove and clean the electrode assembly (see No. 2 above). Check the draft in the stack above the heater. Stack draft (pull in) should be -.02” W.C. minimum to -.05” W.C. maximum. Check for exhaust fans in the heater room or adjacent areas which draw combustion air away from heater. THE HEATER MUST HAVE COMBUSTION AIR TO OPERATE.
