SAFETY DEVICES
Spark Safety Device: Automatically shuts unit down when there is an abnormal spark at time
of ignition.
Flame Failure Device: Activated when burner flame fails. This prevents raw gas from being
released.
Overheat Switch:
Fusible Links:
This device automatically cuts the gas off if the heater exceeds a
predetermined temperature. This is normally caused by an
obstruction in front of the louvers, or a blocked fan filter.
Backs up the overheat switch. If the fusible link cuts the unit off, a
service call by an authorized person is required to replace the link.
Overcurrent Prevention Device: This is a 3 amp. glass fuse found on P.C. board. Design
to shut unit down in case of overcurrent. If fuse blows all
indicator lamps will be "OFF".

PROGRAMABLE WEEKLY TIMER
The Rinnai 431WTA features a weekly timer which allows four separate time periods, each with its own temperature,
to be set.
These periods can be programed differently for each day of the week, or for a group of days: weekdays, weekends
or all days of the week together.
The four timer periods create up to four separate operating intervals, each with its own temperature setting.
The programing covers a 24 hour time span(one day).
The two diagrams below graphically represent an example weekday and weekend program.

The heater will heat the room
to 76°F from 5:30 am until
8:00 am, when period 2
starts.
76°F

Period 2 has a temperature
setting of “nothing” or OFF,

YOUR WEEKLY TIMER PROGRAM
■ Points to consider before writing your program:
When do I want the heater to operate, and what temperature do I want?
When do I not want the heater to operate?
Will I use the same settings for everyday day of the week, or do I need a separate program for the
weekdays, and the weekend? Do I need a separate setting for each day of the week?
■ Points to remember when writing your program:
The four periods are set within a 24 hour time span.
The start of a new period marks the end of the previous one, so each period only requires a START time.
Period 4 ends with the start of period 1 on the next day(see page 26 for a reminder).
Each period must be set to a later time than the one before it.
If you want to heat during the period, select a temperature: H(high), 80 → 60, L(low).
If you do not want to heat during this period, select the OFF setting.
■ Write your own program:
Use the tables below to write your own weekly timer program, then turn to page 28 to program the timers.

After the room is heated initially the air
temperature may be dropped to a lower level
without affecting comfort. 30 minutes after the
selected room temperature (set manually with
the “ ▲ ” and “ ▼ ” buttons or in an On timer
period) is reached, the Economy Mode, if set,
reduces the temperature by 2°F. After another
30 minutes it reduces the temperature by a
further 2°F, effectively saving energy.

PRE-SERVICE CHECK
Before asking for a service call please check the following points.
These points are part of the normal operation of the unit.
I At Ignition:
Is the heater plugged in?
Heater does not operate.
Have the fuses or breaker blown at the switch board?
Is there a power failure?
Is the air filter blocked?
Is anything blocking the outlet for the hot air?
Is the flue blocked?
Are timers set? Clear timers and operate again.
The fan is started automatically after a short delay.
This is to allow the heat exchanger to warm up, helping to avoid cold draughts.
Warm air does not flow when the burner
lights.
This is caused by grease or oil and dust on the heat exchanger and will stop
after a short time.
Smoke or strange smells are produced
on the first trial light up after installation.
This is simply expansion noise from the heat exchanger.
Sharp clicking noises at ignition, or when
unit cuts down on the thermostat, or goes
out.
I During Combustion:
This is the sound of the solenoid gas valves opening and closing.
Clunking noise when the thermostat
operates.
Is the air filter blocked?
Unit is not heating room.
Is the set temperature high enough?
Is the warm air outlet blocked by anything?
Are the doors and windows of the room closed?
Air filter is blocked or the louvers are
blocked or obstructed.
Allow heater to cool, clean air filter, operate again.
Even after unit has cooled down the heater does not ignite again. Repair is
necessary.
Heater will not re-ignite after overheating.
Contact your local agent or Rinnai for a Service call.
I When the unit is turned off.
This is to remove the residual heat from the heat exchanger, the fan will stop
when the heater cools down.
Convection fan continues to run after
turning OFF.
I Other Points:
High efficiency appliances tend to discharge water vapor on cold days, this is
normal.
Steam is discharged from the flue terminal.
Check whether filters are blocked, dirty filters will cause the heater of overheat.
Switch OFF, then ON again when power is restored to re-set controls.
Unit cuts off without apparent reason.
Power Failure longer than 24 hours.

I TYPES COMPATIBLE WITH EXTENSION SET
INSTALLING AN EXTENSION KIT
Installing an extension kit requires construction of an air line and the exhaust line. The air line is connected
between the Air Supply Elbow at the rear of the heater and the air inlet port on the Flue pipe.
Similarly, the exhaust line is connected between the joint pipe at the rear of the heater, and the exhaust
port on the Flue pipe.
Caution: Check to see there is no debris in pipe or hose.
I HOW TO INSTALL
Example:Using 2 sets of extension set and 1 bent set.
Example:Using 80 inches slide pipe set.

The hose can be cut to the required length.
IMPORTANT: The PVC air line is longer than the exhaust line and may need to be cut to size. Be sure,
however, to thoroughly deburr all rough edges.
3. Affixing the air intake hose and exhaust pipe
NOTE: Maintain 1" clearance between exhaust pipe and
combustible materials (0" clearance between exhaust
pipe and non-combustible materials).

I CAUTIONS
1. Maximum extendable length
2. To prevent water condensation
FOR BEST ROOM AIR HUMIDITY, KEEP WATER
IN THE HUMIDIFIER TRAY.
Condensed water
may accumulate
here, and cause a blockage
preventing combustion.
CAUTION
・13 feet, 2 bends
Never allow the exhaust pipe to sag, as condensed
water may accumulate and cause incomplete
combustion.
・The bend where the hose and pipes leave the body is
not counted.
・The air intake hose should run along the exhaust pipe.

3. Condensed water formed by
combustion, will run back to the
unit, and may overflow from the
condensation pan if pipes are
3˚ slope(approximate)
longer then 8 feet. Therefore, pipes
exceeding these lengths should be
made to drain to the outside by
giving their horizontal portions 3˚ or
more downward and outward slope.
4. Wherever the air intake hose and exhaust pipe
run sideways, try to have the exhaust pipe on top
(to prevent the air intake hose from sagging onto
the exhaust pipe).
