Napoleon N370-0877 Base Kit with Burner Components for Prestige PRO 825 & Built-In PRO 825 Grills

What Problem This Part Solves

The base or cookbox is one of the grill's primary structural components. It supports and positions many of the components responsible for cooking, including the main burners and associated burner hardware.

Over years of use, severe heat exposure, grease, corrosion, physical damage, or failed mounting points can make replacement of the entire base assembly more practical than repairing individual areas.

N370-0877 can help restore:

• The primary PRO825 cookbox/base structure

• Proper burner positioning

• Burner component mounting points

• Cross-light system mounting

• Sear plate support locations

• Smoker burner component positioning

• Overall factory configuration of the cooking system

Napoleon's PRO825-3 schematic shows the base directly associated with the N100-0057 main burners, N100-0049 smoker burner, N080-0320/N080-0321 cross-light brackets, N370-0822 sear plate mounts and related components.

Important Generation Note

The PRO825-3 generation is directly confirmed by Napoleon's factory parts manual, which identifies N370-0877 as the base for PRO825-3. 

Older PRO825 generations may use different base assemblies. For example, N010-0814 is separately identified by Napoleon as “ASSY, BASE STN STL PRO825.” Therefore, confirm the complete model number before replacing such a major structural assembly.

Fits most grills within this series—confirm model number before ordering.

Installation / Use Instructions

1. Shut off and disconnect the grill's gas supply and electrical power, then allow the grill to cool completely.

2. Remove the cooking grids, warming racks, sear plates, burners, ignition components, gas-system components and other parts necessary to access and remove the existing base assembly.

3. Install the N370-0877 base kit according to the factory configuration, reconnect all applicable burner, ignition, gas and electrical components, and perform a complete gas leak test before operating the grill.

Because replacing the grill base requires substantial disassembly of the gas and burner systems, professional installation by a qualified gas-service technician is recommended if you are not experienced with gas appliance repair.

FAQ Section

Does this fit my grill?
N370-0877 is confirmed for select Napoleon Prestige PRO 825-3 and Built-In Prestige PRO 825-3 grills. Napoleon lists it for both PRO825RSBIPSS-3 and BIPRO825RBIPSS-3 configurations. 

What exactly is the N370-0877?
Napoleon identifies N370-0877 as “KIT, 825 BASE C/W BURNER COMPONENTS.” The PRO825-3 factory schematic also identifies N370-0877 as the grill's base. 

Does N370-0877 include burner components?
Yes. Napoleon's current official description explicitly states “C/W BURNER COMPONENTS,” meaning the base kit is supplied with burner components. However, Napoleon's online listing does not clearly enumerate every individual component included in the service kit, so unrelated burners, hardware, ignition parts, wiring or gas components should not be assumed to be included. 

Is N370-0877 the same as N010-0814?
No. They are separate Napoleon part numbers. N370-0877 is the 825 base kit with burner components, while N010-0814 is listed separately by Napoleon as the PRO825 stainless steel base assembly. Confirm your grill's model and generation before ordering either major component. 

Why choose the genuine Napoleon N370-0877?
The N370-0877 is the Napoleon-specified base kit for compatible PRO825 models. Because the base establishes critical mounting locations for burners and related cooking-system components, using the correct OEM assembly helps restore the grill's original factory configuration.
