PT70ss Plus Diesel Heater Parts

The nozzle specified for the Lavor PT70ss Plus is a critical component for achieving the quiet, efficient combustion this unit is known for.

For a .040 80° Solid requirement, you are looking for a precision fuel nozzle with the following specifications:

Key Specifications

  • Capacity: 0.40 USgal/h (approx. 1.46 kg/h). This governs the fuel flow rate; using a larger nozzle (like a 0.50) will cause the heater to run too hot and potentially soot up.

  • Spray Angle: 80°. This wide angle is designed for the specific dimensions of the PT70ss combustion chamber to ensure the flame doesn't "lick" the back or sides of the cone.

  • Spray Pattern: Solid (S). A solid cone pattern provides a dense core of fuel droplets, which is essential for stable ignition and a consistent flame in radiant-style diesel heaters.

FUEL FILTER FUEL FILTER
FUEL FILTER

Lavor PT70ss Plus diesel heater, the fuel filter is a critical secondary line of defense for that .040 nozzle. Given the tight tolerances of the nozzle orifice, the filter must meet specific filtration densities to prevent microscopic carbon or sediment from causing a blockage.

Specifications

To match your requirements for a 6mm hose and a 45–60 μm filtration rating, the following specifications apply:

  • Hose Compatibility: 6mm (approx. 1/4") ID (Internal Diameter) fuel line.

  • Maximum Pore Size: $\le 60 \text{ \mu m}$ (Microns). This ensures that no particles large enough to immediately clog the .040 nozzle pass through.

  • Average Pore Size: $\le 45 \text{ \mu m}$ (Microns). This provides the "fine" filtration necessary for the high-pressure pump system.

  • Material: Typically a sintered bronze or high-density mesh element. Sintered bronze is preferred for these heaters because it is depth-loading and can handle the suction pressure of the fuel pump without collapsing.

IGNITER SPARK TRANSFORMER FOR LAVOR HEATER

  • Input: 120V or 240V (Australian models use the 240V/50Hz version).

  • Output: 16.5 kV (High Frequency).

  • Features: Includes two insulated high-temperature spark plug leads (secondary leads) that connect directly to the electrodes.

MAIN BOARD/W THERMOSTAT PORT MAIN BOARD/W THERMOSTAT PORT
MAIN BOARD/W THERMOSTAT PORT
$0.00

MAIN BOARD WITH THERMOSTAT PORT is the central control unit (PCB) that manages the ignition sequence, safety sensors (photocell/overheat), and the thermostat interface.

Specifications

  • Thermostat Compatibility: Includes a dedicated port for an external thermostat, allowing the heater to cycle on and off based on ambient room temperature.

  • Safety Logic: Monitors the flame via the photocell and will trigger an error if the circuit is interrupted.

  • Voltage: Specifically configured for the Australian 240V power standard used in the PT70ss Plus.

HEAT PLATE HEAT PLATE
HEAT PLATE
$0.00

The Heat Plate (also known as the Combustion Chamber Front Plate or Radiant Disc) is a vital structural component for the Lavor PT70ss Plus. This plate sits at the front of the combustion chamber and is responsible for radiating the heat generated by the burner.

Product Details

  • Function: It acts as a thermal barrier and radiant surface, absorbing the direct flame from the .040 nozzle and projecting infrared heat forward.

  • Material: High-temperature stainless steel or specialized alloy designed to withstand constant thermal expansion and contraction without warping or cracking.

  • Replacement Signs: You should inspect or replace the heat plate if you notice:

    • Significant warping that disrupts the airflow or flame pattern.

    • Large cracks or "burn-through" holes in the center of the plate.

    • Excessive scaling or flaking of the metal, which can drop debris into the burner assembly.

DIFFUSER CAP DIFFUSER CAP
DIFFUSER CAP
$0.00

Diffuser Cap (also referred to as the Combustion Head or Burner Head) for the Lavor PT70ss Plus is a crucial component that stabilizes the flame and manages airflow around the Fuel Nozzle.

Function and Importance

  • Flame Shaping: The diffuser cap features specific slots and vanes that create turbulence. This ensures the air mixes perfectly with the atomized fuel from the .040 80° Solid nozzle, preventing a "long" or "unstable" flame.

  • Heat Shielding: It protects the nozzle assembly and Igniter Electrodes from the intense radiant heat of the main combustion chamber.

  • Material: It is constructed from heavy-duty stainless steel to resist oxidation and warping under extreme temperatures.

Signs You Need a Replacement

  • Burn-through: If the edges of the diffuser vanes have thinned or burned away, the air will not swirl correctly, leading to white smoke or "chuffing."

  • Warping: A warped cap can misdirect the flame, causing it to hit the Heat Plate unevenly.

  • Heavy Carbon Buildup: While carbon can often be cleaned off, deep pitting in the metal can harbor hot spots that lead to pre-ignition issues.
