    BLUEHELIX TECH RRT 18S / 24S / 30S 2. Installation 2.1 General Instructions This unit must only be used for its intended purpose. This unit is designed to heat water to a temperature below boiling point and must be connected to a heating system and/or a water supply system for domestic use, com- patible with its performance, characteristics and heating capacity.

  • Page 8: Place Of Installation

    BLUEHELIX TECH RRT 18S / 24S / 30S 2.2 Place of installation The combustion circuit is sealed with respect to the place of installation and therefore the unit can be in- stalled in any room. However, the place of installation must be sufficiently ventilated to prevent the creation of dangerous conditions in case of even slight gas leaks.

    BLUEHELIX TECH RRT 18S / 24S / 30S 2.7 Condensate drain connection IMPORTANT The boiler has an internal trap for draining condensate. Install the push on hose “B” & sediment bowl before commis- sioning, the boiler fill the trap with approx. 0.5 L of water and connect the hose to a solvent welded waste system. For safety reasons the hose must form a tight seal into the waste system.
  • Page 19 BLUEHELIX TECH RRT 18S / 24S / 30S Condensate drain (Please follow BS 6798 or Industry Guidance for Installers on Condensate pipe Installation) The condensate should be run inside as far as is practicably possible. For that purpose, use a pipe of at least 22 mm diameter and a trap with flexible connection supplied with the unit to facilitate connection of the condensate drain pipe.
