Indoor Installation
The Rheem 27 CFWH is available in models suitable for indoor installation. The flue system is room sealed coaxial design manufactured from high grade stainless steel inner and aluminised steel outer.
The maximum flue length with no bends is 13.5m. Reduce the maximum length by 1.5m for every 90° bend and reduce the maximum length by 0.75m for every 45° bend.
Separate ventilation for combustion is not required as the air for combustion is supplied in the flue outer. The flue system can be installed with zero clearances from combustible materials. Flue termination must comply with the requirements of AS/NZS 5601.1.

Rheem Continuous Flow Flue Components
How to Size
Use the following as a guide to selecting the flue components required. The overall dimension of each flue piece is shown in the drawings. Allow approximately 35mm for insertion of each flue piece.
Determine the lineal distance and number of 45° and/or 90° bends between the top of the water heater and flue terminal. Note, the bottom edge of a vertical flue terminal must be 500mm away from the nearest structure in accordance with AS/NZS 5601.1.
Flashing is required to be installed where a vertical flue section penetrates the roof line (not supplied).
Where a condensate drain section is installed, the hose must be connected and drained to the sewer waste or outside. A condensate trap must be installed and filled with water to prevent spillage of products of combustion.
- Flue penetrations through walls and ceilings must be sealed in accordance with local fire regulations
- Rheem CFWH are certified for installation with the terminals closer than that specified in AS/NZS 5601.1.
- Adjacent water heaters may be installed with zero clearance between the water heaters.

Multipak®, Commpak® and Commpak Plus®
The Rheem Commpak range has been developed to provide a pre-engineered solution for commercial hot water applications. Starting with systems as small as two Commercial Continuous Flow through to systems as large as you can imagine.
All systems are pre-assembled on a sturdy aluminium frame, which can be wall or fl oor mounted depending on system size. A range of options are available with all systems.
Multipak®
The range starts with Multipak, which is a staged ignition system available in models comprising two to six Commercial Continuous Flow units. Typically used where large demands are required intermittently, such as in sports clubs. In 60ºC temperature mode, Multipak is suitable for use in dead leg and recirculation systems. 75ºC models are suitable for dead leg applications only.
Installation
All models can be used as an in line booster to solar pre-heat plant and can be used in conjunction with Rheem Guardian® to provide tempered or warm water. The entire Commpak range can be specified for installation outdoors or indoors with Rheem supplied coaxial flue kits. Both indoor and outdoor Commercial Continuous Flow units are certifi ed for installation with zero clearance between water heaters.
