22 Rinnai I-Series Condensing Boiler Combi Manual
1. Determine the terminaon method—horizontal
or vercal, concentric, or twin pipes, etc.
2. Determine proper locaon for wall or roof
penetraon for each terminaon.
3. Install terminaon assembly as described in this
manual or in the vent manufacturer’s
installaon instrucons.
4. Install air and vent piping from boiler to
terminaon.
5. Slope horizontal exhaust run towards the boiler
1/4 in per foot. DO NOT slope combuson air
pipe towards boiler.
6. Install vent supports and brackets allowing for
movement from expansion, or as per vent
manufacturer’s instrucons or local code
requirements.
7. (Oponal step) Install vent screen or room air
lter (not included with purchase) on Schedule
40 PVC combuson air and exhaust terminaon
elbows as illustrated below.
Check to determine whether local codes
supersede the following clearances:
• Avoid terminaon locaons near a dryer
vent.
• Avoid terminaon locaons near
commercial cooking exhaust.
• Avoid terminaon locaons near any air
inlets.
• You must install a vent terminaon at least
12 in above the ground or ancipated snow
level.
Vent Screen
• Press vent screen inside of
terminaon piece/elbow.
• Secure vent screen to the
elbow with screw.
The vent for this appliance shall not
terminate:
• Over public walkways.
• Near sot vents or crawl space vents
or other area where condensate or
vapor could create a nuisance or
hazard or cause property damage.
• Where condensate or vapor could
cause damage or could be detrimental
to the operaon of regulators
pressure relief valves, or other
equipment.
Listed below are important consideraons
for locang vent terminaon under a sot
(venlated or unvenlated or eave vent; or
to a deck or porch):
• Do not install vent terminaon under
a sot vent such that exhaust can
enter the sot vent.
• Install vent terminaon such that
exhaust and rising moisture will not
collect under eaves. Discoloraon to
the exterior of the building could
occur if installed too close.
• Do not install the vent terminaon too
close under the sot where it could
present recirculaon of exhaust gases
back into the combuson air intake of
the terminaon.
Horizontal porons of the venng system
shall be supported to prevent sagging:
• For category IV boilers, have
horizontal runs sloping upwards not
less than 1/4 in. per foot (21 mm/m)
from the boiler to the vent terminal;
• For category IV boilers, be installed so
as to prevent accumulaon of
condensate; and
• For category IV boilers, where
necessary, have means provided for
drainage of condensate.
