Care of your iHeat
Your iHeat system needs very little maintenance, however the following information will keep it
working efficiently.
Cleaning the return air filter
Your iHeat system has a large
return air grille through which air
is returned to the iHeat for
reheating. The return air grille
contains a filter that traps dust
and other particles from the air.
This needs to be cleaned regularly
(every 2-4 weeks). If this is not
done you may notice increased
noise at the return air grille.
To clean the return air filter:
1. Remove filter from return air
grille housing.
2. Clean any dust or debris from
both sides of the filter using
a vacuum cleaner, a soft dry
cloth, or a soft brush. Do this
on a flat surface to stop the
frame from bending out of
shape.
3. If required, wipe down the
return air grille using a damp
cloth.
4. Return the filter to the return
air grille and secure the grille
in place.
Cleaning the Rinnai Infinity
water filter
Cleaning the Infinity
water filter will reduce the
likelihood of blockages
to the water heater which
could cause insufficient
water flow to the iHeat.
It is recommended the water filter
is cleaned every year. This would
normally be completed by a Rinnai
Service Centre as part of annual
servicing, but could be needed
inbetween times if you experience
any problems with insufficient
water flow to the pump.
To avoid burns wait until
the water heater cools
before cleaning the water
filter as hot water may drain from
the unit if there has been recent
hot water use. Turn off the gas and
power to the Infinity.
1. Unscrew the water filter from
the position marked in the
diagrams below.
2. Flush the filter using clean
water.
3. Replace the water filter.
4. Turn on the gas and power to
the unit.

Rinnai has a

For reliable operation the Rinnai
iHeat and Rinnai Infinity unit
should be serviced annually.

is not covered by the Rinnai

work on your system other than
that mentioned in this guide. If
