FLAT PREHEATER RETROFIT INSTRUCTIONS

EnergyLogic has developed a new oil preheater design that uses a flat, finned extrusion to provide surface area for heat transfer. The design is backwards compatible with the retrofit kit, but the oil inlet is in a different location, so the copper tubing from the pump will need adjusting. The new preheater is similar to the previous design in that it uses standby and run PTC heaters, as well as a thermostat to ensure that the oil is heated before allowing the burner to fire.

The main advantage of the new design is that the electrical components (heaters and thermostat) are on the outside. This allows them to be easily removed, so the extrusion and cover can be cleaned in a parts washer, the electrical components can be easily replaced if one fails, and the PTC heaters can be changed to allow the preheater to be used on different models.
