PILOT CLEANING PROCEDURE
FOR HOMEOWNERS
N
OTE: if the pilot assembly on your appliance is not a Rinnai pilot you must contact the
manufacturer of that pilot assembly for cleaning instructions. Failure to follow the manufacturer's
instructions could cause damage to the appliance and/or serious injury to the person performing
this task.
In order to properly clean the Rinnai pilot assembly shown below, you will need 120 psi of
compressed air. In the drawing below, please find the venturi on your pilot assembly, indicated by
the arrow. When this venturi becomes clogged with dust/lint, you can blow through the venturi
using high-
p
ressure air (120 psi) to dislodge any foreign matter. A good indicator for a dirty pilot
is a yellow tip in the pilot flame. The most common statements we hear associated with dirty pilot
are; my heater is getting harder and harder to light, the heater is shutting off for no reason, and I
need a thermocouple. The above three items are very good indicators that you have a dirty pilot.
Remember, cleaning of dust/lint is not a warranty issue. In over 98% of all pilot problems, it's a
dirty pilot. Vacuum cleaners, furnace blowers and hair dryers do not provide enough air or
suction to clean your pilot properly. If you follow this procedure using high-pressure air (120
p
si), your appliance will deliver many years of trouble free service.

TDM-VF 2004www.rinnai.us 6
PILOT CLEANING PROCEDURE
FOR TECHNICIANS
In order to properly clean the pilot orifice
and air venture:
First, remove pilot burner gas tube, then
blow through the pilot orifice with 100 psi
compressed air in the same direction the gas
flows through the orifice. See arrow #1 for
location as to where air nozzle should be
placed.
Second, to ensure venture on bottom side o
f
p
ilot burner is clear, use 100 psi compressed
air to blow out venture at location indicated
by arrow #2.
Note: This procedure is recommended only
for Rinnai heaters. Contact manufacturer
for other brand units.

TDM-VF 2004 www.rinnai.us7
COPRECI O.D.S. PILOT CLEANING PROCEDURE
FOR TECHNICIANS
CLEANING INSTRUCTION OF COPRECI (O.D.S.) PILOT ASSEMBLY
In order to properly clean the pilot assembly and air venture – turn the heater to the off position
and shut off the gas supply. Then proceed as follows.
First, grip the spring lock for the air shutter with a
pair of pliers. Press down with pliers to allow lock
spring to release. Use caution, do not bend the bi-
metal strip when removing and re-installing the
lock spring. The lock spring should come out
without any restriction. When the lock spring is
removed, the brass air shutter will drop down. This
will allow you to see up inside the pilot assembly
where the gas and air mix. Usually, you will note a
big ball of dust/lint just behind the shutter.
Second, to ensure all dust/lint is removed from this location, take 100 psi compressed air and
hold the nozzle back about six inches from the shutter gap and blow out all debris. Reassemble
air shutter in reverse order of disassembly. Be careful not to drop lock spring in carpeting and
lose it.

PROPER BURNER CLEANING INSTRUCTIONS
N
OTE: Service must be performed by a qualified installer, service agency or gas technician.
Remove the unit from the structure before performing this cleaning due to the dust created by
this cleaning procedure. In order to properly clean the burner on a Rinnai Vent Free radiant
heater, you will need an air compressor capable of delivering 120 psi of compressed air. Using
an air gun or nozzle, blow directly into the burner plaques from about four inches away. Take
time to blow through each of the holes in the plaques. This will take about three minutes if done
p
roperly. After blowing the burner out fire the unit and let it operate for two minutes. Cut the
unit off and repeat the above procedure three additional times: Some problems caused by dirty
b
urners are; humming and/or air noises, dull plaques, and over-burning at the top of the plaques.
Units cleaned annually as stated in the owner's manual, normally do not encounter these
p
roblems. Burners are replaced as an assembly. Plaques or bricks are not available individually.

HOWTO CHECKATHERMOCOUPLEAND MAGUNIT
WARNING: There are a number of “live” tests that are required to be done in fault
finding. Extreme care should be used at all times. You MUST be a qualified service
person before proceeding with these test instructions. Before checking resistance readings,
turn off power switch and then isolate items to be checked from circuit (unplug it).
Thermocouple checking procedure (Screw in type):
Set your voltage meter to a DC milli-volt scale. This scale should be able to read above 35 milli-volts. Place the red
lead of your meter to the copper lead and the black lead to the dome of the thermocouple. The dome is the portion
of the thermocouple that goes up into the gas valve. See drawing below for location to place meter leads. The
above procedure is for screw in type thermocouples. Now apply heat to the thermocouple. If the thermocouple is
good, you will see the milli-volt output on the voltage meter start to increase. Maximum output will be somewhere
b
etween 24 to 30 milli-volt. After you have eliminated the thermocouple as the source of the problem, proceed with
the pilot cleaning instructions.
Thermocouple checking procedure (Plug in type):
Set your voltage meter to a DC milli-volt scale. This scale should be able to read above 35 milli-volts. Place one
lead of your meter into each receptacle of the plug as shown below in the drawing. Now apply heat to the
thermocouple. If the thermocouple is good, you will see the milli-volt output on the voltage meter start to increase.
Maximum output will be somewhere between 24 to 30 milli-volt. After you have eliminated the thermocouple as
the source of the problem, proceed with the pilot cleaning instructions.
Proper procedure for checking the magnetic unit (Screw in and plug in types):
Remove the magnetic unit from the gas valve. Once it has been removed, reconnect the thermocouple to the
magnetic unit. Then apply heat to the thermocouple while pressing down on the spring loaded plunger, (see drawing
b
elow). Hold the plunger down until it bottoms out for thirty seconds at the same time heat is being applied to the
thermocouple. After thirty seconds, release the plunger. If the magnetic unit is good, it will stay in the bottomed out
p
osition by itself. After cooling for a brief period, it should release and spring back out to the relaxed state. If it
doesn’t stay down when released, the magnetic unit is defective and should be replaced.

TDM-VF 2004 www.rinnai.us11
MANIFOLD & PILOT GAS PRESSURE CHECKING
N
ote: Service must be performed by a qualified installer, service agency, or gas technician.
Any time you are having problems with a gas appliance, one of the first things you should
check is the operating manifold pressure. In the left hand drawing below, please find the
manifold pressure test port on Rinnai Infra-Red Radiant Heater. This test port is plugged
with an allen type plug with white pipe dope on it. This plug varies in location. You will
need a 3/16" allen wrench to remove this plug. Theplugthreadsare1/8" NPT (national pipe taper).
Connect your U-tube manometer up to this test port, fire the unit and record the manifold pressure.
Proper manifoldpressurescanbefound on the rating plate of each appliance or in the owner's
manual. If the manifold pressure is found to be low, reinstall the pressure test port plug and
check for proper inlet pressures. If the inlet pressure is found to be correct, then you know your
p
roblem is in the unit .It could be a bad appliance regulator or gas control. If the inlet pressure is
low, then you know the problem is in the gas supply feeding the appliance.
CHECKING FOR PROPER GAS PRESSURE TO THE PILOT ASSEMBLY
Disconnect the pilot gas line from the ODS pilot assembly. (See picture above showing pilot
assembly – disconnect gas line at the arrow in the right hand drawing.) Connect your U-tube
manometer to the pilot assembly gas line. Turn the control knob to the pilot position and press
down on the knob as you would when lighting the pilot. With the knob pressed down, check
your manometer for any indication of gas pressure. Your manometer should indicate pressure at this
p
oint indicating proper gas feed to the pilot. Ifthere IS PRESSURE found at this test point, this indicates that
the pilot assemblyis clogged and needs cleaning. Ifthere is NO PRESSURE at this test point, it indicates that
the gas control, pilot regulator, appliance regulator, or supplypressure could be the problem. Follow the steps
in the manifold gas pressure check above to eliminate the gas supplyas the problem.

MPORTANT SAFETY NOTES:
There are a number of (live) tests that are required to be done in fault finding. Extreme care should be used at all
times. You MUST be a qualified service person before proceeding with these test instructions. Before checking
resistance readings, turn power switch off, and isolate item to be checked from circuit (unplug it).
(TR) Transformer:
Wire colors Voltage readings Resistance readings Pin #'s
Brown ~ Brown 21.5 ~ 23 VAC 1.1 ~ 1.8 ohms 39 ~ 42
Blue ~Blue 09.5 ~ 11 VAC 10.1 - 10.8 ohms 40 ~ 43
Black ~ White 100 ~ 110 VAC 79.5 ~ 81 ohms 41 ~ 44
(IG) Ignitor:

(SV1 , SV2 , and POV) Gas valve solenoids:
SV1 = Blue ~ Blue 85 ~ 95 VDC 1,400 ~ 2,000 ohms 48 ~ 50
SV2 = Yellow ~ Yellow 85 ~ 95 VDC 1,400 ~ 2,000 ohms 48 ~ 50
POV = Red ~ White Low-fire 1.8 ~ 2.5 VDC 80 ~ 100 Ohms 32 ~ 33
Hi.-fire 9.4 ~ 12 VDC
(FM) Convection Fan Motor:
Blue ~ Yellow (329A/429A) Lo. fire 48.5 VAC 138 ~ 142 ohms 45 ~ 46
Brown ~ Brown (229A) Hi. fire72.5 VAC
Convection fan motor RPM's are as follows. The RCE229A Natural gas unit on high fire should be set at 950 rpm's,
low fire 730 rpm's. The RCE229A Propane gas unit on high fire should be set at 950 rpm's, low fire 680 rpm's. The
RCE329A Natural gas unit on high fire should be set at 850 rpm's, low fire 570 rpm's. The RCE329A Propane gas
unit on high fire should be set at 870 rpm's , low fire 520 rpm's. This data is for reference only, you can not adjust
RPM's.
(TF) Thermal Fuse/OHS:
White ~ black 24 ~ 30 VDC O ohms (as if meter leads were touching) 34 ~ 36
(TH) Thermistor:
Check thermistor by inserting meter leads into each end of the thermistor plug, pins 30 - 31 yellow to yellow wires.
Set your meter to the 200k ohm scale and read resistance across the thermistor bulb. You should be able to apply
some ice to the thermistor bulb and the resistance should increase. When heat is applied to the bulb the resistance
decreases. See example resistance readings and temperature readings for several different temperatures below.
Example:
41 degrees = 91 k ohms
50 degrees = 65 k ohms
68 degrees = 39 k ohms
86 degrees = 23 k ohms
S
ub P.C. Board:
Black ~ Grey 118 ~ 125 VAC n/a 41 ~ 44
Black ~ White 118 ~ 125 VAC n/a Electrical Supply

TDM-VF 2004 www.rinnai.us17
(TC) Thermocouple or ODS device:
Connect your meter leads to the thermocouple output terminals at the back of the appliance or pin numbers 28 and
29. This terminal is on the right side of the unit directly above the air filter. The round plug slot is the negative lead
and the square slot is for the positive lead. Normal milli-voltage output on low fire is above 18 milli-volts. High fire
is normally above 16 milli-volts. Minimal output is 16 milli-volts, maximum is 35 milli-volts. If the milli-voltage
output remains below 16 milli-volts for 60 seconds, the unit will shut down on safety. If this occurs check for a
defective thermocouple, improper alignment, or carbon build up on thermocouple.
(OH. TH.) Overheat thermistor:
The overheat thermistor is located just under the front panel attached to the burner housing. This unit connects to the
P.C. board at pins 37 and 38 yellow and blue wires. About six inches out from the board , there is a plug in this
harness. The wires on this harness turn white at that point. See example below for resistance and temperature
readings.
Example:
61 degrees = 114 k ohms
64 degrees = 105 k ohms
68 degrees = 98 k ohms
72 degrees = 91 k ohms
75 degrees = 84 k ohms
79 degrees = 79 k ohms
ON/OFF Switch for the RCE229/329A/429A:
On the RCE229A , read resistance across the red wire at pin #14, and white wire at pin #16 on the P.C.Board. In
order to check the on/off switch operation you must unplug this terminal. Then connect your meter to the terminals
as indicated above. There should be no reading until you press the on/off button, then you should read continuity
through this circuit.
INFORMATION CONCERNING LOCKOUTS:
There are several factors that can cause units to shut off for no reason, that are not a fault of the appliance. Check for
improper line sizing , supply regulators freezing up or defective, low pressure or pressure drops due to other
appliances on the system, improper or no ground at the receptacle, voltage drops or bad receptacles, high altitude
applications, etc. The best way to eliminate any of these items as the source , is to remove the appliance and take it
b
ack to your shop where it can be connected to a known gas and electrical source. If you do this and the problem
goes away, you know then the problem is in the gas or electrical supply at the customer's home.
Items to check for in odor complaints:
N
ew carpet, drapes, furniture, paint, chemical treatments of any kind, spraying of aerosols, pets, smoking, burning of
candles and potpourri, excessive dust/lint inside the casing, contaminated ambient air, etc.
