This heater has an automatic ignition system. When the main burner has lit, the combustion lamp will glow red, and the spark will stop.
Operating the Heater Manually Lock Sensible Temperature Control This feature locks the buttons to prevent unintended operation. The sensible temperature control feature allows comfortable heating which matches the conditions in the room. Press the Lock button to activate and the lamp will glow. Pressing and holding the Lock button for two seconds will disengage the Lock. Lock If the Lock is engaged while the unit is operating, all buttons will be disabled except for the ON/OFF button.
Care and Maintenance Maintenance Filters All maintenance and service are to be performed by a qualified service technician, preferably one who has attended Rinnai service training classes on the Direct Vent products. Dirty filters reduce the air flow and the appliance’s ability to produce heat. The filters should be cleaned frequently during the heating season. If the filters become blocked the filter indicator lamp will flash and the appliance will beep.
Before Making a Service Call Before making a service call please check the following: At Ignition: Heater does not operate. Is the heater plugged in? Have the fuses or breaker blown at the fuse box / breaker panel? Is there a power failure? Is the air filter blocked? Is anything blocking the outlet for the hot air? Is the flue blocked? Warm air does not flow when the burner lights. The fan is started automatically after a short delay.
Fault Codes If there is a malfunction the appliance may shut down as a safety precaution and display a fault code to assist in diagnosing the problem. The fault code will flash in the display on the control panel. When making a service call, this code will assist with diagnosing the fault. CODE DISPLAYED You may be able to clear the fault code by turning the heater off and then on again.
Restart Function If the appliance fails to ignite, the appliance will attempt ignition after 1 hour. The “Ignition Failure” fault code, 11, will appear during that hour and disappears after a successful ignition. If ignition fails again, then the fault code will remain and another attempt to ignite will occur in 1 hour. The fault code is not stored in the fault code history. If the flame is extinguished during forced combustion then the appliance will attempt ignition after 1 hour.
Installation Instructions General Instructions WARNING Do not use substitute materials. Use only parts certified with the appliance. • A qualified service technician should install the appliance and inspect it before use. • If you move, check the gas type in your new area. The local gas authority will be able to advise on local regulations. • The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.
Gas Connection WARNING When connecting the gas valve or other gas components in the gas line, use a backup wrench to ensure the connection is gas tight. • The gas supply line shall be gas tight, sized and so installed as to provide a supply of a gas sufficient to meet the maximum demand of the heater without loss of pressure. • A shut off valve and appliance connector valve should be installed in the upstream of the gas line to permit servicing.

Drilling Flue Hole NOTICE Use a template (included) to determine allowable location of the flue hole For installation without using extension kits, the configuration of the flue manifold, air intake hose, and exhaust slide pipe should be as shown when installation is completed. Exhaust slide pipe Minimum Exhaust slide pipe Maximum Drill the flue hole using a 3 1/8 inch (80 mm) drill. The center of the hole must be located anywhere within the shaded area, unless extension kits are used. See diagram.
Flue Manifold Installation • The flue manifold must exhaust to the outside. Do not exhaust into other rooms. • The flue manifold is not designed to be positioned under floors or below the heater. • This appliance can only be used with one of the five types of Rinnai flue kits. The flue kits and their dimensions are listed on the previous page. • Refer to the Flue Terminal Clearances section. • The termination cannot be vertical. 1.
Flue Manifold Installation 4. Install the Terminal Check that the terminal seal is in place. For weatherboard walls, add the second seal next to the terminal seal to compensate for weather board angle. Terminal seal From the outside insert the terminal into the sleeve with the marking “TOP” at the top. The left hand side locking tie should be marked “LEFT”. Terminal Locking tie 5. Lock the ties Pulling hard on the left and right hand ties, clip the ties over the notches inside the sleeve.
Extension Kit Installation If necessary, extension kits are available to extend the exhaust line and air intake hose between the manifold and the appliance. (1) Maximum vent length allowed is 13 feet (4 m). (2) Maximum vertical length allowed is 8 feet (2.4 m). (3) Any length (horizontal and vertical) in excess of 8 feet (2.4 m) must be sloped 3° downward toward the flue manifold to allow condensate to drain to the outside. (4) Do not allow any low points in the exhaust line where condensate will collect.
