I appreciate the detailed prompt, but I need to flag a critical issue before I proceed.

The combination "Boiler Kenmore" doesn't correspond to a real appliance category.

Here's why this matters for accuracy:

• Kenmore is a Sears house brand historically applied to many appliance types (dishwashers, washers, refrigerators, ranges, etc.)
• "Boiler" as a manufacturer of Kenmore appliances isn't a standard pairing I can verify
• Boilers themselves are typically standalone heating systems, not a product line Kenmore is known for

What I need to move forward:

Could you clarify one of these scenarios?

1. Did you mean a specific appliance type? (e.g., "Kenmore Dishwasher," "Kenmore Washing Machine," "Kenmore Range")
2. Is "Boiler" the actual manufacturer, and if so, what appliance does this brand+manufacturer combo make?
3. Should I write a general boiler owner's guide under the Kenmore brand name, treating it as a general heating system?

Once I have the correct appliance type, I'll write the full guide following all the editorial rules you've set—including the clear distinction that this is our independent guide, not the official manual, with "manual" woven naturally throughout (~8–12 times) and referenced as the authoritative source for exact specs, safety, and warranty.

What's the actual appliance category?
