Rinnai M-Series Condensing Boiler Combi Manual
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in personal injury or death.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It may also be used to alert against unsafe practices.
The following precautions apply to the installer and consumer. Read and follow all instructions in this section.
•Before operating, smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
•Keep the area around the appliance clear and free from combustible materials, gasoline, and other flammable vapors and liquids.
•Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
•Combustible construction refers to adjacent walls and ceiling and should not be confused with combustible or flammable products and materials. Combustible and/or flammable products and materials should never be stored in the vicinity of this or any gas appliance.
•Always check the water temperature before entering a shower or bath.
5
•Do not use this appliance if any part has been under water. Immediately call a licensed professional to inspect the appliance and replace any part of the control system and any manual gas control valve which has been under water.
•Do not use substitute materials. Use only parts certified for the appliance.
•Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
•It is strongly recommended that you use a trained and qualified professional who has attended a Rinnai installation training class to adjust parameter settings.
•Do not use an extension cord or adapter plug with this appliance.
•Any alteration to the appliance or its controls can be dangerous and will void the warranty.
•To protect yourself from harm, before performing maintenance:
−Turn off the electrical power supply by unplugging the power cord or by turning off the electricity at the circuit breaker. (The boiler controller does not control the electrical power.)
−Turn off the gas at the gas control, usually located immediately below the boiler.
−Turn off the incoming water supply. This can be done at the isolation valve immediately below the boiler for the domestic hot water. Turning off the water for the central heating system is done at the boiler system filling station shut-off valve or the main water supply to the building.
−Use only your hand to turn the manual gas control valve. Never use tools. If the manual gas control valve will not turn by hand, do not try to repair it; call a trained and qualified professional. Force or attempted repair may result in a fire or explosion.
•Proper venting is required for the safe operation of this appliance. Failure to properly vent this appliance can result in death, personal injury and/or property damage.
•Flammable liquids such as cleaning solvents, aerosols, paint thinners, adhesives, gasoline and propane must be handled and stored with extreme care. These flammable liquids emit flammable vapors and when exposed to an ignition source can result in a fire hazard or explosion. Flammable liquids should not be used or stored in the vicinity of this or any other gas appliance.
•DO NOT operate the boiler without the front panel installed. The front panel should only be removed for service/ maintenance or replacing internal components.
•BURN HAZARD. Hot exhaust and vent may cause serious burns. Keep away from the boiler. Keep small children and animals away from the boiler.
•Heating supply, return and domestic hot water outlet pipes leaving the boiler can be hot to touch.
•Install the vent system per local and national codes.
•Do not install this boiler above 10,200 ft (3,109 m).
•Do not obstruct combustion air to the boiler.
•Rinnai recommends that every home have a carbon monoxide (CO) alarm in the hallway near bedrooms in each sleeping area. Check batteries monthly and replace them annually.
•California law requires the following Proposition 65 warning to be provided:

When choosing an installation location, you must ensure that clearances will be met and that the vent length will be within required limits. Consider the installation environment, water quality, and need for freeze protection. Requirements for the gas line, water lines, electrical connection, and condensate disposal can be found in their respective installation sections in this manual.
This section provides information on the importance of water quality to the Rinnai Condensing Boiler. The information is intended to serve as general guidelines only and is not a complete list of water quality guidelines.
Consideration of care for your boiler should include evaluation of water quality.
•The water must be potable, free of corrosive chemicals, sand, dirt, or other contaminants.
•It is up to the installer to ensure the water does not contain corrosive chemicals or elements that can affect or damage the boiler.
•Water that contains chemicals exceeding the levels below can damage the boiler.

Drinking Water Regulations
•Unsuitable heating system water can cause the formation of scale or sludge, which affects system efficiency. It can also cause corrosion and reduce life of the heat exchanger.
•Never use water that has been treated by a reverse osmosis, deionized, or distilled water to soften the water to fill the heating system.
•For Domestic Hot Water systems, if you install the boiler in an area that is known to have hard water or that causes scale buildup, the water must be treated and may require a more frequent flushing schedule. Scale build-up is caused by hard water and can be accelerated if the boiler is set at a high temperature. Rinnai offers Southeastern Filtration’s “ScaleCutter Water Conditioning System” that offers superior lime scale prevention and corrosion control by feeding a blend of control compounds into the cold water supply.
•Oxygen permeable or rubber tubing is not permitted in the heating system unless it is separated from the boiler by a plate heat exchanger. The boiler warranty may be voided if connected directly to CH systems that include this tubing.
•Thoroughly flush the system prior to filling. While flushing, isolate the boiler.
•Do not introduce any system cleaner into the boiler. Flush the system thoroughly to remove all system cleaner before filling the boiler with water.
•When freeze protection of the heating system is desired, only use Rinnai-approved antifreezes. The allowed maximum concentration is 50%.
•Reference section “14.1 Approved Cleaners, Inhibitors and Antifreezes” in the Appendix for an approved list of system cleaners, inhibitors, and antifreezes.
IMPORTANT
Replacement of components due to water quality damage is not covered by the warranty.

Rinnai M-Series Condensing Boiler Combi Manual |
Air surrounding the boiler, venting, and vent termination(s) is used for combustion and must be free of any compounds that cause corrosion of internal components. These include corrosive compounds that are found in aerosol sprays, detergents, bleaches, cleaning solvents, oil based paints/varnishes, and refrigerants. The air in beauty shops, dry cleaning stores, photo processing labs, and storage areas for pool supplies often contains these compounds. The boiler, venting, and vent termination(s) should not be installed in any areas where the air may contain these corrosive compounds.

Topics in this section
•Guidelines
•Venting Installation Sequence
•Termination Considerations
•Venting Options
•M-Series boilers can be installed in direct vent or non-direct vent applications.
•When installed as Direct Vent, refer to the following section for a complete list of approved vent manufacturers and products: “5.4.1 Direct Vent: Approved Vent Manufacturers and Products.”
•When installed as Non-Direct Vent (Room Air), the vent must be Category IV and of a type listed by a national recognized testing agency.
•Exhaust must be directly vented to the outside. Combustion air can be provided from outside (Direct Vent) or from room air (Non-Direct Vent).
•If using room air (non-direct vent) for combustion, ensure the required volume of indoor air is available according to the National Fuel Gas Code, ANSI Z223.1/NFPA 54.
•Avoid dips or sags in horizontal vent runs by installing supports per the vent manufacturer’s instructions.
•Support horizontal vent runs every 4 ft (1.2 m) and all vertical vent runs every 6 ft (1.83 m) or as per vent manufacturer’s instructions or local code requirements.
Rinnai M-Series Condensing Boiler Combi Manual
•Venting should be as direct as possible with a minimum number of pipe fittings.
•For manufactured vent systems, vent connections must be firmly pressed together so that the connections form an air tight seal. Follow the venting manufacturer’s instructions.
•Refer to the Schedule 40 PVC/CPVC manufacturer for appropriate fittings, solvents or joining methods.
•If venting reassembly is needed, follow the steps for installing the venting in the following sections. Make certain that the vent piping and seals are not damaged. Only use sealants, primers, or glues that are approved for the vent material in use.
•Refer to the instructions of the vent system manufacturer for component assembly instructions.
•If the vent system is to be enclosed, it is suggested that the design of the enclosure shall permit inspection of the vent system. The design of such enclosure shall be deemed acceptable by the installer or the local inspector.
•Any issues resulting from improper vent installation will not be covered by warranty.
WARNING
•DO NOT use cellular core PVC/CPVC.
•DO NOT use Radel, ABS, or galvanized material to vent this appliance.
•DO NOT cover non-metallic vent pipe and fittings with thermal insulation.
•DO NOT combine vent components from different manufacturers.
•DO NOT reduce the vent diameter. Vent diameter cannot be less than 2 in.
•DO NOT connect the venting system with an existing vent or chimney.
•DO NOT common vent with the vent pipe of any other manufacturer’s boiler or appliance.
21
1.Determine the termination method— horizontal or vertical, concentric, or twin pipes, etc.
2.Determine proper location for wall or roof penetration for each termination.
3.Install termination assembly as described in this manual or in the vent manufacturer’s installation instructions.
4.Install air and vent piping from boiler to termination.
5.Slope horizontal exhaust run towards the boiler 1/4 in. per foot. DO NOT slope combustion air pipe towards boiler.
6.Install vent supports and brackets allowing for movement from expansion, or as per vent manufacturer’s instructions or local code requirements.
7.(Optional step) Install vent screen or room air filter (not included with purchase) on Schedule 40 PVC combustion air and exhaust termination elbows as illustrated below.
Vent Screen
Room Air Filter
•Press vent screen inside of termination piece/ elbow.
•Secure vent screen to the elbow with screw.
Press air filter into the 3 in. (80 mm) PP intake air fitting on the boiler.
Check to determine whether local codes supersede the following clearances:
•Avoid termination locations near a dryer vent.
•Avoid termination locations near commercial cooking exhaust.
•Avoid termination locations near any air inlets.
•You must install a vent termination at least 12 in above the ground or anticipated snow level.
The vent for this appliance shall not terminate:
•Over public walkways.
•Near soffit vents or crawl space vents or other area where condensate or vapor could create a nuisance or hazard or cause property damage.
•Where condensate or vapor could cause damage or could be detrimental to the operation of regulators pressure relief valves, or other equipment.
Listed below are important considerations for locating vent termination under a soffit (ventilated or unventilated or eave vent; or to a deck or porch):
•Do not install vent termination under a soffit vent such that exhaust can enter the soffit vent.
•Install vent termination such that exhaust and rising moisture will not collect under eaves. Discoloration to the exterior of the building could occur if installed too close.
•Do not install the vent termination too close under the soffit where it could present recirculation of exhaust gases back into the combustion air intake of the termination.
Horizontal portions of the venting system shall be supported to prevent sagging:
•For category IV boilers, have horizontal runs sloping upwards not less than 1/4 in. per foot (21 mm/m) from the boiler to the vent terminal;
•For category IV boilers, be installed so as to prevent accumulation of condensate; and
•For category IV boilers, where necessary, have means provided for drainage of condensate.
