Possible Causes
Improper flue termination location, Inadequate flue support, Wind gusts causing pressure switch trips, Recirculation of exhaust gases into intake
How to Fix / Troubleshooting
Safety first: Do not modify flue terminations without following Rheem and local code requirements.
- Step 1 – Observe conditions: Note if lockouts occur only during high winds. Check for related error codes (often air pressure or flame loss).
- Step 2 – Inspect terminations: Ensure the Rheem boiler’s intake and exhaust terminations meet clearance requirements from corners, windows, and other vents. Correct any obvious violations.
- Step 3 – Check supports: Make sure flue and intake pipes are securely supported and not moving excessively in the wind.
- Step 4 – Wind shields: A qualified installer may add approved wind shields or adjust termination style to reduce wind effects, following Rheem guidelines.
Warning: Do not improvise flue terminations or cover them in ways not approved by Rheem; this can cause dangerous combustion issues.
