If you have an installation that varies from that detailed in this guide, please contact Rinnai. Evolve vs. Arriva installation There are some flue installation differences between the Evolve and the Arriva. The main points of difference are the flue kits and the way in which condensate is handled. • Direct flue kit for the Evolve Due to the size of the Evolve unit and the cavity dimensions the only direct flue kit the Evolve can use is the ASPDFK. The direct mushroom A and B flue kits (R2731 and R2732) are not suitable as the telescopic exhaust section of the fire is not long enough to connect to the flue transition. • Adaption flue kit Arriva uses ASPKIT03 and Evolve uses EVOKIT03, refer p. 8 for more information. • Condensate A condensate trap is required for all vertical flue installations to ensure condensate generated during combustion is trapped and prevented from entering the combustion chamber. For the Arriva a condensate drain kit needs to be installed (p. 22). For the Evolve the condensate drain tube is connected directly to the condensate pipe on the heater— refer to the Evolve installation guide, section ‘Install heater into enclosure’.

Evolve models ASPDFK A/B flue kits Arriva/Evolve flue installation guide: 10726-G 07-15 | 5 Important For all flue installations there are some important ‘must-dos’ to ensure the flue is installed correctly. These are summarised below. Flue must be secure To prevent the flue from moving or coming apart: • The joints between the flue components MUST BE secured by screws (easier to undo if necessary) through the outer pipes. • The flue components MUST BE clipped to the wall using the wall straps provided in each flue kit. Connecting flue components Inner pipe joints are sealed with an o-ring seal lubricant. A small plastic tub of silicone grease is provided with the main flue kits. Use this silicone grease to lubricate the o-rings on the inner pipes prior to assembly. This is important as the o-rings can dry out and break, and replacing o-rings is difficult. DO NOT use petroleum based lubricants such as petroleum jelly. Petroleum jelly or other similar lubricants will cause deterioration of the o-ring seals. ASPDFK component The minimum length of the ASPDFK when measured from the back plate of the transition casting MUST NOT be less than 300 mm when joining to other components. Flue sections located outside Sections of the flue located outside require the following precautions: • Only use PVC cement between the joints of the outer PVC pipes to secure and seal the joints against ingress of dust and water. • Only use non-acidic silicone sealant between the joints of the outer PVC pipe and any mating aluminium components (such as the condensate trap) to secure and seal these joints against ingress of dust and water— silicone containing acetic acid or other acids as the curing agent may cause the aluminium to corrode. ESBEND installation and connection If installed incorrectly there is potential for the outer bend to overheat. A separate installation sheet is provided with each ESBEND kit to ensure correct alignment of the bend component. Condensate trap A condensate trap is required for all vertical flue installations to ensure condensate generated during combustion is trapped and prevented from entering the chamber of the heater. In vertical installations the condensate trap MUST BE installed in a vertical position. 2° fall to the wall terminal For direct, sideways and down- and-out flue installations, there must be a continuous fall of at least 2° to the wall terminal. This equates to 20 mm per metre to the termination point to drain the condensate. The Arriva Direct A and B flue kits (R2731/ R2732) have an inbuilt 2° fall. 2° fall back to the heater Required when any part of the flue system goes horizontally then vertically. Down rating the appliance For all flueing EXCEPT direct flueing, the appliance must be down rated (ensures optimum performance of the fan) as per the instructions on the commissioning sheet. Termination point Flue is not to terminate under floors or in a roof space.

These must be read and modified as necessary with reference to the particular installation. The Rinnai Arriva/Evolve must be installed with an approved Rinnai flue system. Approved flue components are detailed in this guide. Clearance to combustibles • Flue transition (p. 10) - 5 mm • Elbow component of adaption flue kit (ASPKIT03/ EVOKIT03) - 25 mm All other flue components have zero clearance. Flashings Flashings are not part of the flue kit and must be specified. Flue support The weight of the flue system should not be supported by the appliance—it should be self-supporting. Supporting the flue is usually completed during the framing stage with flue supports or straps within the cavity. Shared flues Gas appliances must not be connected to a chimney or flue serving a separate fuel burning appliance. Horizontal terminations The flue must terminate in accordance with AS/NZS 5601.1. Especially relevant is the requirement to have a 300 mm minimum clearance between the flue terminal and ground level. Vertical terminations: Flue cowl clearance To ensure products of combustion are cleared, adequate clearance from the building is required. The flue cowl should have a 500 mm clearance from any part of the building. This also applies to steeped and pitched roofs which should be clear of the ridge line. Lesser clearances may provide perfectly adequate flue systems depending on the installation. Minimum clearances are shown in AS/NZS 5601.1 Maximum flue length and number of bends Max. flue length - 8.5 m Max. number of bends - 3 One 90 ° bend equals 1 m. For every 90 ° bend the overall length must be reduced by 1 m. For example, if an installation has three 90 ° bends, the maximum flue length is 5.5 m. The elbow component of the ASPKIT03/EVOKIT03 is counted as a 90° bend. Every gas fireplace requires a flue system that will draw effectively and clear flue products safely under all potential wind and climatic conditions. It is the responsibility of the installer to ensure that the appliance is provided with an effective flue. Minimum clearance 500 mm to nearest part of roof 300 mm clearance Horizontal terminations Vertical terminations Arriva/Evolve flue installation guide: 10726-G 07-15 | 7 Flueing options The below options detail the most common types of flue installations. If you have an installation that varies from those below, please contact Rinnai. For further detail on each of the options refer pages 12-18. Arriva flue components - Direct A flue (R2731), or - Direct B flue (R2732), or - Direct flue (ASPDFK) Evolve flue components - Direct flue (ASPDFK) * Adaption flue kit: Arriva use ASPKIT03, Evolve use EVOKIT03 • Maximum flue length - 8.5 m • Maximum number of bends - three • One 90 bend = 1 m For every 90 ° bend the overall length must be reduced by 1 m. For example, if an installation has three 90 ° bends, the maximum flue length can be 5.5 m. The ASPKIT03/EVOKIT03 is counted as one 90 ° bend.
