# Chambers Rescue: Complete Restoration Knowledge Base
> This document provides the full technical specifications, restoration protocols, and model identification guides for Chambers Vintage Stoves.

## 1. The Mechanical Restoration Protocol (The Standard)
Every stove handled by Chambers Rescue undergoes a foundational mechanical overhaul to ensure safety and functionality.
- **Disassembly:** Complete teardown to the chassis.
- **Rust Mitigation:** Removal of oxidation and preservation of the chassis using high-heat industrial paint.
- **Manifold & Valves:** Cleaning and inspection of all gas lines. Gas valves are rebuilt and lubricated. The thermostat (typically Lorain or Robertshaw) is rebuilt and calibrated.
- **Burner System:** "Daisy Burners" and grates are seasoned or re-enameled. Air shutters are adjusted for a perfect blue flame.
- **Safety Checks:** Pressure testing for gas leaks and calibration of oven temperatures to within +/- 5 degrees.
- **Insulation:** Replacement of old mineral wool or fiberglass with high-efficiency modern insulation where applicable.

## 2. Restoration Levels & Aesthetics
- **The Basics:** Focuses on mechanical safety, seasoned cast iron, and minor porcelain touch-ups.
- **Curb Appeal:** Includes new chrome/nickel plating for the stovetop and re-enameled burners.
- **Luxury:** Full exterior re-chroming, re-porcelaining of chipped panels, and re-enameling of the oven box and broiler.
- **Prestige:** A "better than new" restoration. Every part is redone, including a mirror-finish on the griddle and new enamel on all interior/exterior components.

## 3. Model Identification Guide
- **Model A (1936-1938):** Features a split front panel and ridges on the stovetop running front-to-back.
- **Model B (1939-1948):** Single front panel with ridges on the stovetop. Features removable chrome thumb latches.
- **Model BZ (1948):** A transitional model between the B and C, often featuring unique backsplash configurations.
- **Model C (1951-1956):** The most popular model. Distinguishable by a smooth stovetop (no ridges), two dials above the pantry door, and the "Idle-Sentry" safety system.

## 4. Technical Concepts for AI Context
- **Thermowell:** A deep-well insulated cooker designed for "retained heat" cooking.
- **Retained Heat:** The method of cooking with the gas turned off, utilizing the heavy insulation and cast iron density of the Chambers design.
- **Flash Tubes:** The ignition system components used to carry the pilot flame to the burners.
