released.

Overheat Switch: 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.

Fusible Links: 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).

A detailed step-by-step guide of setting the times and temperatures shown in the two examples above are given on

pages 28-29.

Before setting the heater we encourage you to think about and write down your own program. A blank table is provided

on page 31 for you to do just this.

The example weekday

program period 1 has been programed to start at 5:30 am with a temperature setting of 76°F.

The heater will heat the room

to 76°F from 5:30 am until 8:00 am, when period 2 starts.

Period 2 has a temperature

setting of “nothing” or

OFF, and so the heater will not operate again until the start of period 3 at 5:00 pm, when it will heat the room to 72°F.

Period 4 turns the heater

OFF again until period 1

starts the timer cycle on the

next day.

The two diagrams below graphically represent an example weekday and weekend program.

For example if you get up

later on the weekends period 1 begins heating the home to 76°F at 9:00am.

The heater has also been

programed to start heating the home earlier in the afternoon, and so period 3 starts at 4:00pm with a temperature setting of 72°F.

Period 4 now has a

temperature of

LOW [50°F],

and runs the heater on this setting all night.

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.

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.

■ At Ignition:

Heater does not operate.

Warm air does not flow when the burner lights.

Smoke or strange smells are produced on the first trial light up after installation.

Sharp clicking noises at ignition, or when unit cuts down on the thermostat, or goes out.

■ During Combustion:

Clunking noise when the thermostat operates.

Unit is not heating room.

Air filter is blocked or the louvers are blocked or obstructed.

Heater will not re-ignite after overheating.

■ When the unit is turned off.

Convection fan continues to run after turning OFF.

■ Other Points:

Steam is discharged from the flue terminal.

Unit cuts off without apparent reason.

Power Failure longer than 24 hours.

Is the heater plugged in? 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.

This is caused by grease or oil and dust on the heat exchanger and will stop after a short time.

This is simply expansion noise from the heat exchanger.

This is the sound of the solenoid gas valves opening and closing.

Is the air filter blocked? Is the set temperature high enough? Is the warm air outlet blocked by anything? Are the doors and windows of the room closed?

Allow heater to cool, clean air filter, operate again.

Even after unit has cooled down the heater does not ignite again. Repair is necessary. Contact your local agent or Rinnai for a Service call.

This is to remove the residual heat from the heat exchanger, the fan will stop when the heater cools down.

High efficiency appliances tend to discharge water vapor on cold days, this is normal.

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.

■ 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.

■ HOW TO INSTALL

Example:Using 2 sets of extension set and 1 bent set. Example:Using 80 inches slide pipe set.

2. How to connect air intake hose

Screw hose joint half of its length onto the air intake hose, then screw another air intake hose into the joint. 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.

・Set the air intake hose and exhaust pipe into the pipe clamps, screw the clamp onto the wall fixture, and affix to the

wall with screw B.

・The air intake hose and exhaust pipe can also be screwed onto the wall using the pipe clamp and

the nut.

■ CAUTIONS

1. Maximum extendable length

FOR BEST ROOM AIR HUMIDITY, KEEP WATER IN THE HUMIDIFIER TRAY.

2. To prevent water condensation

Condensed water may accumulate here, and cause a blockage preventing combustion.

・13 feet, 2 bends ・The bend where the hose and pipes leave the body is

not counted.

・The air intake hose should run along the exhaust pipe.

CAUTION

Never allow the exhaust pipe to sag, as condensed water may accumulate and cause incomplete combustion.

Page 62

– 60 –

3. Condensed water formed by combustion, will run back to the unit, and may overflow from the condensation pan if pipes are 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.

3˚ slope(approximate)

Less than 8 ft.

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).

QUALIFIED INSTALLING AGENCY

The installation must conform to local codes, in the absence of local codes, the installation must conform with American National Standard (National Fuel Gas Code) known as NFPA 54 and ANSI Z223.1.1992. Available from the American National Standards Institute, Inc., 1430 Broadway, New York, N.Y. 10018 or from the National Fire Protection Association, 470 Atlantic Avenue, Boston, Mass. 02210.
