1. Check dimensions of the opening
Refer 'Enclosure dimensions' and if necessary bring them to the required dimensions.
Check the chimney height as inadequate height can eect product performance. Some
installations may require the chimney height to be extended to reduce down drafts.
2. Check ueway
• Ensure there are no obstructions
• Provide a rm, at and sealed base (sealed means no holes or openings in the replace)
• Ensure adequate support of the appliance (if not properly supported noise and vibration
may result)
3. Install exiliner ue system
To ensure adequate draw for maximum performance of the appliance, Rinnai strongly
recommends the use of a Rinnai exiliner ue system for masonry installations. Failure to meet
this installation criteria may result in an unsafe situation. Performance issues resulting from
inadequate ueing is not covered by the warranty.
Installation without a exiliner is permissible in masonry installations as long as the chimney
has been checked for soundness and ability to achieve a good draw.
