Rinnai RHFE 952 ETRN Operation & Installation Manual page 36

INSTALLATION
Install burn media - stones
The glass retainer will need to be removed before installing the stone set and granules. Use extreme care when
handling the stones, they are made from a fragile material and will damage easily.
Use these instructions in conjunction with the burn media guide sheet, which is attached to the
engine. Experience has shown that the majority of performance problems have been caused by
the burn media being installed incorrectly.
IMPORTANT
It is important to place the pieces in the correct position. Incorrect placement can create carbon build-up and
affect performance. Malfunctioning due to improper stone/granule placement is not covered by warranty. The unit
must never be used with broken stones or other burn media (except those specifically designed for the Evolve).
Before commencing installation ensure you have the correct stone set. The RHFE 952 stone set contains 30
stones, the RHFE 1253 stone set contains 40 stones. The installation between the two models varies slightly.
