Overview

This document describes the installation of the Dometic Secondary Burner Housing Assembly Kit, part number 3311145.000, designed for Americana/AMES/AES 2-Way Refrigerators. This kit is intended to enhance the safety and performance of specific Dometic refrigerator models by providing a protective housing for the burner and related components.

Function Description:

The Secondary Burner Housing Assembly Kit serves as a protective enclosure for critical components of Dometic 2-Way Refrigerators, specifically the burner, heating element, and thermal fuse. Its primary function is to improve safety by containing the burner and preventing accidental contact with hot surfaces or potential ignition sources. The kit also includes a thermal fuse and associated wiring, which are crucial for safety by interrupting power in case of overheating.

The kit's installation involves several key components:

  • Protection Plate, Back (Item 1): This plate is installed behind the flue jacket, fitting flat against the backside of the refrigerator cabinet, extending to the bottom and side, and placed behind the liquid temperature exchanger. It provides an additional layer of protection and insulation.
  • Bottom Plate (Item 2): This plate slides into position with mounting tabs facing up, resting on the refrigerator leg. It may require modification (shearing along score lines) to fit units with existing sheet metal barriers under the burner. This plate forms the base of the burner housing.
  • Holder (Thermal Fuse) (Item 3): This component secures the thermal fuse in place on the boiler cover.
  • Cover (Heating Element) (Item 4): This cover is installed over the heating element, providing protection and ensuring proper heat distribution.
  • Boiler Cover (Item 5): Shipped flat with angled edges, this cover needs to be formed into an approximately 6-inch circle to fit around the cooling unit flue jacket. It encloses the boiler area, contributing to the overall housing.
  • Rear Cover (Item 6): This cover is installed at the rear of the assembly, aligning with holes in the boiler cover and bottom plate to complete the enclosure.
  • Thermo Disc (Item 7): This component is installed on the flue jacket using pop rivets and is connected to the thermal fuse, acting as a temperature-sensitive switch.
  • Thermal Fuse (Wire) (Item 13): This fuse is connected to the thermo disc and the 12 VDC terminal block, providing an essential safety cutoff in case of excessive heat.
  • Wire, Complete (Item 12): This wire connects the thermo disc to the power module (J4 or T4 terminal on non-universal power modules, J1 on universal power modules).

The kit is designed for Dometic refrigerators that operate on both LP gas and 120 VAC energy sources, referred to as 2-Way refrigerators. The installation process may involve removing and reinstalling the burner and its cover, depending on the refrigerator's ventilation grille mounting and the need for access.

Usage Features:

This kit is not a user-operated device but an installation for a refrigerator. Its features are primarily related to safety and improved functionality of the refrigerator:

  • Enhanced Safety: By enclosing the burner and heating element, the kit reduces the risk of accidental contact with hot components and potential fire hazards. The thermal fuse provides an automatic shutdown mechanism in case of overheating.
  • Compatibility: Designed specifically for a range of Dometic 2-Way refrigerator models and serial numbers, ensuring proper fit and function.
  • LP Gas and 120 VAC Operation: The kit integrates with refrigerators capable of operating on both LP gas and 120 VAC power sources, maintaining dual-fuel functionality.
  • Modular Design: The kit consists of several distinct parts (plates, covers, fuse, wiring) that are assembled to create the complete housing, allowing for a structured installation process.
  • Professional Installation Required: The instructions explicitly state that the kit must be installed by a Dometic Service Center or a qualified service technician due to the hazardous nature of modifications and the need for specialized knowledge.
  • Pre-Installation Safety Precautions: Crucial steps include turning off the LP gas supply at the tank, unplugging the 120 VAC refrigerator power cord, and disconnecting the 12 VDC supply line at the source to prevent personal injury or property damage.
  • Gas Leak Testing: If the gas line or burner requires loosening or removal during installation, a gas leak test using a calibrated manometer and commercial leak detecting fluid is mandatory after reassembly. This ensures the integrity of the LP gas system.
  • Component Verification: Before installation, all items in the kit must be verified against the contents list.
  • Screw Retention: All removed screws during disassembly must be saved for reinstallation.
  • Wiring Diagram Placement: The appropriate wiring diagram (Item 15) must be placed on the outside center of the rear cover after installation, serving as a future reference for service. The correct diagram is chosen based on the power module cover's height (approximately 4 inches for universal power modules, larger for non-universal or integrated ignition power modules).
  • Post-Installation Checks: After installation, the refrigerator's operation on both electric and gas must be checked, and the lower side vent access door reinstalled, ensuring the drain water hose is in its correct position.
  • Gloves Recommended: Wearing gloves is recommended during installation to avoid injury.

This kit is a critical safety upgrade for specified Dometic refrigerators, ensuring the safe and reliable operation of the appliance's heating and cooling systems.
