Confirm transformer is producing adequate voltage by evaluating the spark
to ground. The unit should be able to bridge at least 3/8” gap.
If Flame Goes Out
Is the thermostat calling for heat?
Clean electrodes and restart.
Check fuel level in tank. Do not draw from bottom half of drum. Refill tank
and restrt..
Fuel excessively wet? Warm fuel to break emulsions, drain off water on
bottom. Use Fuel Enhancement Procedure.
Clogged intake screen. Fuel pump is straining to take in fuel due to a
screen becoming clogged. Clean screen, replace gasket and restart.
Check the fire eye for any soot accumulation, clean as necessary.
Check air pressure is adequate, i.e. 20 to 40 psi.
Fire eye sees residual flame from accumulated carbon residue and stops re-
ignition. Wait until residual flame dies out.
Flame Wrong Size
Adjust position of Flame Control relative to fuel intake. I
f flame is too
large, push Flame Control to the front of the burner, if too small, move
Flame Control to the rear. Use small increments of change, approximately
1/16 inch at a time.
Intermittant Flame
An inconsistent or sputtering flame indicates lack of continuous spark. This
may be caused by air in the fuel stream or by carbon buildup on the
electrodes. Always start by cleaning the electrodes and check for
performance. If sputtering persists, check all connections on the suction
side of the pump are tight. An air leak can be at gaskets on the Strainer or
the Fuel Pump. The positive displacment fuel pump will create great
suction. If the intake screens are becoming clogged, the pump may pull in
air through a gasket. Clean intake screens as required so the liquid transfer
does not meet strong resistance. Change gaskets on fuel strainer and pump
housing whenever these are opened.
Smoke Visible from Either over-firing or under-firing may cause smoke. Adjust Control
Chimney
Rod accordingly.
Pump or Compressor Shop air, i.e. a remote air compressor is the preferred source of compressed
air. An on-board small compressor is available as an option. Try plugging
appliance into regular wall plug. If it still won’t run, contact Homestead
Inc. for replacement pump or compressor under one year warranty or for
repair parts.
