GENERAL INSTALLATION METHODS Lubricating Components A container of "O ring" grease is provided with the flue terminal components (FFWALLTERM and FFROOFCOWL). To ease assembly, lubricate the “O” ring on the inner pipes of each flue component prior to assembly. Use only a silicone based "O" ring seal lubricant. DO NOT use petroleum based lubricants such as petroleum jelly, as such products may cause deterioration.
DIRECT HORIZONTAL FLUE The Rinnai water heater 'direct' flueing components (FFSBEND, FFWALLTERM, FFWSEAL and FFWPLATE) must be used for this purpose. Installation method 1. Mount the water heater in an appropriate location ensuring that there is enough space to install the flue assembly and pipe work. Also ensure that positioning of the flue terminal complies with the requirements of AS/NZS 5601 see (Fig.6.2 on page 9). Ø127 Wall penetration FFSBEND 3.
VERTICAL FLUE This option can be used when the water heater is to be flued vertically through the roof. The Rinnai water heater 'Vertical Flueing Components' (FFROOFCOWL and FFPIPE1000) with extension pieces (FFPIPE1000) and optional roof seal (FFSEAL) must be used for this purpose. With vertical flue systems the condensate drain pipe will require connection if the total length of the flue system exceeds 2 metres. Refer to the section “CONDENSATE DRAIN” on page 6 for details.
CONDENSATE DRAIN The condensate trap and associated drain connection are integral with the appliance flue spigot. The condensate trap collects any condensate from the flue system, thereby preventing condensate from entering the water heater and causing damage. A condensate drain tube kit is supplied with the terminals (FFWALLTERM and FFROOFCOWL) and will require connection to the condensate drain connection in flue systems where the total length exceeds 1.
CONDENSATE DRAIN Installation Method (a) The drain line MUST NOT discharge onto electrical connections, earth stakes, copper pipes, concrete paths or into a pond. (b) The point of discharge from each drain line shall be located so that the release of condensate does not cause a nuisance, is readily discernible and incurs no risk of damage to the building. In view of (a) and (b), suitable points of discharge are deemed to be drains, sewers or pits.
