- Material durability: Opt for heat- and corrosion-resistant plastics or metals rated for outdoor exposure and high exhaust temperatures.
- System compatibility: Some kits are tailored for Rheem or similar brands. Verify model compatibility with your unit before purchasing.
- Installation ease: Kits that come with screws and simple mounting steps save time and reduce the need for tools beyond basics.
