Stable Support & Fixation Gas Water Heater Base Shell/Back Plate/Inner Chassis Anti-Deformation & Durable

Product Overview
This white powder coated integral inner back plate is the main mounting base frame of tankless instant gas water heater. Made of thickened cold rolled steel with full anti-rust white powder coating, it adopts integrated stamping and bending process with complete reserved mounting holes, ventilation heat dissipation slots and positioning buckles. All core internal components of the water heater including burner assembly, exhaust fan, gas proportional valve, main control board and flow sensors can be fixed on this plate uniformly. The heat dissipation slotted design solves the problem of heat accumulation inside the equipment, while the anti-rust coating resists long-term steam and flue gas erosion. It is a complete replacement spare part when the original back plate is rusted, deformed or damaged during water heater maintenance.

Main Advantages
All-in-one Universal Mounting Base
Unified installation platform for all internal spare parts, greatly simplify the assembly and maintenance work of water heater, reduce installation time.

Long-lasting Anti-corrosion White Spraying Layer
Electrostatic powder spraying forms dense protective film on the steel surface, effectively prevent rust perforation caused by condensed water inside the machine.

Optimized Internal Heat Dissipation System
Strip air slots balance air circulation inside the water heater, avoid heat buildup around electronic parts and extend the service life of control board and sensors.

High Strength Anti-deformation Steel Structure
Thickened steel sheet maintains flat shape after long-term heavy load, will not warp or sag to cause component offset.

Precise OEM Matching Hole Layout
All hole positions and buckle structures are produced according to universal water heater mold, perfectly fit original accessories without secondary processing.

Safe Burr-free Smooth Edge
One-time stamping deburring treatment, eliminate the risk of wire scratching and short circuit during installation.

Installation Tips
Align the four corner fixing holes of the back plate with the outer shell of the water heater and lock evenly with screws to avoid unilateral stress deformation.

Install internal components one by one according to the reserved hole positions, match the buckle clips to lock each part tightly.

Do not scratch the white sprayed coating surface during installation to retain anti-rust performance.

Replace the back plate in time if the coating peels off or the steel plate is severely rusted and deformed.

FAQ:
What is the function of the Gas Water Heater Base Shell?
Answer: It is the bottom shell of the gas water heater, used to fix and protect the internal core components (such as water tank, combustion chamber), prevent dust, water and foreign objects from entering, and stabilize the whole machine.

Why does the Gas Water Heater Base Shell loosen after long-term use?
Answer: Loose fixing screws, vibration during the water heater operation, deformation of the base shell, or missing fixing buckles.

What is the function of the Gas Water Heater Back Plate?
Answer: It is the back panel of the gas water heater, used to fix the water heater on the wall, protect the internal wiring and components, and isolate the wall from high temperature.

What is the function of the Gas Water Heater Inner Chassis?
Answer: It is the internal main chassis of the gas water heater, used to fix all internal core components (such as combustion chamber, water tank, fan, control board), and isolate and protect the components from mutual interference.

Why does the Gas Water Heater Inner Chassis make abnormal noise during operation?
Answer: Loose components fixed on the chassis, deformed chassis causing component misalignment, or foreign objects stuck between the chassis and components.
