Methodology

We start with current manufacturer product pages, manuals, catalogs and specification sheets. We preserve exact-model dimensions and unknown fields rather than inferring installation data from retailer summaries.

Primary-source rule

Current manufacturer manuals, catalogs, product pages and specification sheets take priority for cutout, clearance, fuel and electrical claims. We do not infer missing installation dimensions from nominal product size.

Installation-safety rule

Our content is for planning and product comparison. Final gas, electrical, ventilation, combustible-clearance and code decisions must follow manufacturer instructions and qualified local professionals.

Testing language

We do not claim hands-on testing unless it actually occurred and is documented.
