    INSTALLATION – WATER HEATER THIS WATER HEATER IS FOR INDOOR INSTALLATION ONLY. THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. Check the water heater is suitable for the gas type available. (refer to the rating label on the water heater) The 864 series of water heater may be installed as an in-series gas booster water heater to a solar preheat water heater.
  • Page 44 INSTALLATION – WATER HEATER VENTILATION This water heater is to be installed with a Rheem coaxial flue system. The kit enables a room sealed installation, drawing air for combustion from outside of the building. The ventilation of a room or an enclosure such as a cupboard, where the water heater is installed must comply with NZS 5261.
  • Page 45 INSTALLATION – WATER HEATER MAINS WATER SUPPLY Where the mains water supply pressure exceeds that shown in the table below, an approved pressure limiting valve that does not have non return valve characteristics (such as an RMC PSL series valve) is required and should be fitted as shown in the installation diagram (refer to page 55).
  • Page 46 99°C if the solar preheat water heater does not have an over temperature protection system to limit the water to no greater than 90°C, such as the Rheem Premier Hiline thermosiphon closed circuit system. Warning: Temperature controllers must not be fitted to this water heater as part of a solar water heater system (864 series) because water at a temperature much higher than the controller setting can be delivered.
  • Page 47 INSTALLATION – WATER HEATER Where a temperature limiting device is installed adjacent to the gas booster water heater, the cold water line to the temperature limiting device can be branched off the cold water line either before or after the isolation valve and pressure limiting valve to the solar storage tank, but it MUST BE before the non return valve prior to an open circuit direct system.
  • Page 48 INSTALLATION – WATER HEATER CIRCULATED HOT WATER FLOW AND RETURN SYSTEM A Rheem 864 series continuous flow water heater can be installed as part of a circulated hot water flow and return system in a building. If a circulated flow and return system is required, it is necessary to bypass the continuous flow water heater and install a secondary water heater connected to the hot water flow and return line and supplied from the continuous flow water heater.

  • Page 64 FLUEING HORIZONTAL FLUE INSTALLATION Horizontal Flueing – Directly Behind Water Heater This method of flue installation is used where the secondary flue is to penetrate and terminate immediately behind the wall on which the water heater is mounted. Do not plumb the water heater prior to this type of flue installation, as the water heater (if mounted) requires to be removed from the wall prior to the final installation of the flue.
  • Page 65 FLUEING Note: Steps 10 to 15 can only be conducted whilst the water heater is off the wall. Connect the Water Heater Flue Adapter (PN 295121) to the water heater flue outlet. Fit the end of the adapter down over the water heater flue outlet as far as it will go.
  • Page 66 FLUEING Horizontal Flueing – Extended Flue Run Notes: • Ensure each flue component is fully engaged and the rubber seal on the inner duct is well seated at each joint. • Each flue component is supplied with screws to connect to the adjacent flue component. The screws are located in a bag taped to the outside of the flue component.
  • Page 67 FLUEING Carefully remove the template inserted as the middle pages of this installation instructions booklet. Cut along the middle of the bold circle marked “Cut Line”. Align the top of the circular template with the mark on the wall. It may be convenient to tape the template to the wall. Mark the pilot hole through the centre of the template and scribe around the template onto the wall.
  • Page 68 FLUEING A horizontal run of flue between two bends, where the bend closest to the flue terminal is orientated upward, must have a gradient upward in the direction of the flue terminal. The Adjustable Straight Length (PN 295127) may be required if a special length is required between offsets or changes in direction of the flue or to ensure the outer skin of the Horizontal Flue Terminal extends a minimum of 75 mm from the face of the external wall.
  • Page 69 FLUEING VERTICAL FLUE INSTALLATION Suitable flashing (not supplied) is required to waterproof the roof penetration. Notes: • Ensure each flue component is fully engaged and the rubber seal on the inner duct is well seated at each joint. • Each flue component is supplied with screws to connect to the adjacent flue component. The screws are located in a bag taped to the outside of the flue component.
  • Page 70 FLUEING Horizontal flue runs between bends must have a minimum upward gradient towards the flue terminal of 20 mm per metre. Note: Ensure that the seam of the inner flue in horizontal runs is towards the top of the installation. Secure each flue component using the sheet metal screws provided.
  • Page 71 FLUEING Apply an adequate bead of sealant around the flue assembly and flashing and around the flashing and roof material, using a general purpose silicone sealant suitable for outdoor application. Failure to properly seal the flue penetration through the roof will result in long term damage due to weather conditions.
  • Page 72 FLUEING MULTIPLE WATER HEATER FLUE INSTALLATION Where multiple water heaters are installed, each water heater must be individually flued to the outside. A common flue system MUST NOT be used. For a multiple unit installation, the water heater is certified for installation with zero clearance between adjacent water heaters.
  • Page 73 FLUEING MULTIPLE WATER HEATER CONDENSATE DRAIN LINE AND CONDENSATE TRAP INSTALLATION Where multiple water heaters are installed and each flue has a Condensate Drain Section fitted, it is necessary to install a condensate drain line for each Condensate Drain Section.
