Combustion Chamber Pressure Relief - Rinnai Symmetry RDV3611 Maintenance Instructions Manual

Combustion chamber pressure relief

A check on the combustion chamber pressure relief should be performed before the glass
frame is removed. This is to ensure the springs that operate to release the glass panel (when
there is gas build-up) are in good working order.
With hands placed either side of the glass panel, pull the glass panel towards you. Do this at the bottom and
at the top of the panel as shown.
Check the combustion chamber pressure relief is working freely and for any signs of corrosion. From the
resting position, the spring should move freely (approximately 25 mm).
Ensure the springs:
- travel freely without sticking
- move at least 25 mm
