The Metro fire brick is common to both current and superseded Metro wood fires to make part selection and replacement easy. Most models feature 2x firebricks (1x each side) and some superseded models featured one of these fire bricks on the rear wall of the firebox (a brick retainer clip will feature on these models).
Model exceptions that feature their own unique fire bricks are:
- All Ultra Fire models
- Wee Rad V2 (superseded model)
- LTD Mega Built-In (superseded model)
