Weaving, bending or uneven flames in a U30 firebox often point to a worn pressure relief door seal. The Urbana U30 Relief Gasket (part 50-3910) is a genuine Urbana two-piece gasket set that seals the firebox's pressure relief door, and it fits the Urbana U30.

Fit

• Sized specifically for the Urbana U30; the U50 and U70 use a different relief gasket set, so this one is matched to the U30 firebox.

When to replace it

Urbana's U30 maintenance checklist calls for a visual check of this gasket for damage or deterioration. A damaged or misaligned gasket breaks the firebox seal, which shows up as weaving or uneven flames, and a worn seal can let combustion gases escape into the home, so replace it once wear is visible.

What's in the kit

• Two relief gaskets, sized for one U30 pressure relief door.

Installation

Let the appliance cool completely before removing and replacing the gasket.
