PROGRAMABLE WEEKLY TIMER The Rinnai 556WTA 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).
PROGRAMING THE WEEKLY TIMERS The following is a general outline of the setting options and procedures avaliable when programing the weekly timers. A detailed step-by-step example is given on pages 28 to 29. Note: Before programing the current time and day must be set. See page 24 for instructions. The weekly timers can be easily programed by following the steps illustrated below: 1 Press the “Timers” button once to activate the timer programing mode.
PROGRAMING THE TIMERS : EXAMPLE Note: Before programing the timers, the clock must be set to the correct time(see page 24).

WEEKLY TIMER REVIEW FUNCTION This function lets you review all of the programed Weekly Timer settings(times and temperatures) without the option of adjusting these settings, removing the danger of accidently changing the program. This is a quick way to review the Weekly Timer program before operating the timers.
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.
OPERATING THE TIMERS ■ Before operating the timers, please check the following points: The clock must be set to the current time and day - refer to page 24 for clock setting procedure. You may want to enter your own timer program. See page 26 for an overview of how the timers work, and page 27 for an explaination of how to set the timers. Page 31 also provides a space for you to write your own individual program.

TESTING CHECK Testing Unit Fault-Failure Procedure Purge air from gas line. Refer to pipe sizing chart if in doubt about the size of the gas line. Connection can easily be reached from the top, rear of the unit. Check for leaks, using soapy water after turning gas on. If unable to get the unit to operate correctly, contact Rinnai Agent, or Gas Utility. Please read the fault finding charts before reporting faults. Do not use this heater if any part has been under water.
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. 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. Warm air does not flow when the burner lights.
TROUBLE SHOOTING Takes too long to warm the room Noisy ignition Smell of gas Combustion stops during operation Unusual combustion Cause No ON indicator Problem Burner doesn't ignite Your RHFE-556WTA requires very little maintenance, simply clean the rear fan filter once a week and wipe the outer case and louver section with a damp cloth.

■ 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.
2. How to connect air intake hose Air intake hose Air intake hose Hose joint Screw in counterclockwise Main unit air intake hose Air intake elbow 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. 3.
3˚ slope(approximate) Less than 8 ft. 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. 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).
