2.7 Fitting the Domus 297 condensate drain kit
2.7.1 Using a small amount of solvent weld suitable for ABS pipe fittings (not supplied), attach the
threaded socket to the selected condensate outlet spigot (see no 2.1.9). Important: follow the
health and safety and user instructions supplied with the solvent weld. This is particularly
important when working in confined spaces.
2.7.2 When the threaded socket is secure, fit and hand-tighten the threaded elbow, making sure
that the rubber seal washer is seated correctly. Gently push the waterless trap onto the elbow
stem.
Important: check that the arrows printed on the trap point away from the HRX2
appliance (in the direction of flow) and prior to fitting, ensure that the waterless trap operates
correctly by running a trickle of water from a tap through the trap in the direction of the arrows.
2.7.3 Using the remainder of the kit items complete the condensate drain-system to suit the
dwelling layout. Important: the drain must incorporate a continuous fall of approximately 0.5º
(9mm in every 1000mm) to the nearest waste water network.
2.7.4 The condensate drain system should be adequately supported and suitably insulated if it
passes through unheated spaces and voids (e.g. loft spaces) to prevent freezing.
2.8 Ducting guidelines
2.8.1 Please refer to the design drawings for the proposed ducting layout.
2.8.2 Four Ø150mm diameter sockets are provided for connecting the ducting. Rigid ductwork
should be securely connected to the sockets using Domus DDSEAL acrylic sealant; failure to
do this will cause unnecessary air leakage and impair performance. Ducting must be
connected to all four sockets according to left or right-hand configuration (see 2.2.7).
2.8.3 Alternatively, heavy duty flexible hose connection kit, HRX2-CK1, is available to make
soft/offset connections between the HRX2 and the rigid duct system.
2.8.4 Where ducting passes through unheated areas and voids (e.g. loft spaces) it must be
insulated using Domus Thermal duct insulation in order to comply with The Building
Regulations. Additionally, both ducts connecting the HRX2 to outside must be insulated when
passing through heated areas to avoid condensation forming on the outside of the ducts.
