Ventilation; Secondary Flue; Pipe Cover - Rheem 27 Owner's Manual And Installation Instructions

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.

SECONDARY FLUE

A secondary flue must be installed with an indoor water heater to discharge combustion products to outside
the building. The water heater MUST ONLY be installed with a Rheem approved coaxial flue system.
Where more than one water heater is installed, each water heater must be individually flued using a Rheem
approved coaxial flue system. A common flue system MUST NOT be used.
Refer to "Flueing" on page 57 for details on the flue requirements and installation details.

PIPE COVER

The pipe work to the water heater can be housed within a pipe cover. A pipe cover kit (PN 299848) is
available for such an installation. Refer to the installation instructions which accompany the pipe cover kit.
FROST PROTECTION
The water heater has a frost protection system. The frost protection system will protect the water heater from
damage, by preventing ice forming in the waterways of the water heater, in the event of freezing conditions
occurring.
The frost protection system will be rendered inoperable if electrical power is not available at the water heater.
Damage to the water heater caused by freezing of the pipe work to or from the water heater is not covered
under warranty. Refer to AS/NZS 3500.4 for precautions to be taken for installations in frost prone areas.
The water heater is not suitable for installation in areas where the ambient temperature falls below -20ºC
(including wind chill factor).
The cold water line to the water heater must be insulated with suitable thickness insulation if freezing
conditions are likely to occur. The insulation must be fitted to the underside of the water heater and be
weatherproof and UV resistant if exposed.
