VERTICAL ON WALL FLUE INSTALLATION ‘Vertical On Wall’ Flue Installation - (Page 4 - Options II a. and II b.) This flue system is used when the flue is to be run vertically up the face of the rear wall of the heater enclosure to either a horizontal or vertical terminal. • The 'On Wall' flue kit is not suitable for installation inside a wall cavity. NOTE 1. Components Condensate Trap The (ASPKIT03) components are shown in the photo.
VERTICAL ON WALL FLUE INSTALLATION 3. Access to flue connection at the heater Refer to section “Access to flue connection at the Heater” on page 12. 4. Connecting and securing metal flue spigot from heater to flue a.) Lift locking tab from slide tube assembly on heater. Remove slide tube from flue pipe on heater. b.) Fit flue slide tube into the flue system transition casting. c.
VERTICAL THROUGH WALL FLUE INSTALLATION ‘Vertical through the Wall’ Flue Installation (Page 4 - Option III ) This system is suitable for appliances installed against solid brick walls, or where a direct flue terminal cannot be used. 1. Components • Direct flue kit (ASPDFK) • Condensate trap (ESCONDK) • 2 x 45° Bends (ESBEND) • Suitable number of Co-axial flue pipes (ESPIPE900) • Vertical terminal if required (ESROOFCOWL) Horizontal termination is also possible.
VERTICAL THROUGH WALL FLUE INSTALLATION 3. Shortening Direct Flue kit follow steps a.) to j.) a.) Slide the round metal wall plate over the end of the Direct Flue Kit and push all the way up until the round metal wall plate rests against the cast stops incorporated in the transition casting.
VERTICAL THROUGH WALL FLUE INSTALLATION • IMPORTANT • The horizontal section of the flue system must be secured by the screws or rivets as described to prevent possible accidental dislodgement which could result in a dangerous situation. The ‘TOP’ marking on the pastic cover must be at the BOTTOM for through the wall vertical co-axial flue installations only to ensure correct condensate drainage. 4. Extending Direct Flue Kit Follow steps a.) to m.) below a.
VERTICAL THROUGH WALL FLUE INSTALLATION j.) Slide the newly cut flue pipes through the wall, and centre the positioning of the outer flue pipe within the hole through the wall. k.) Slide plastic external wall cover plate over the flue pipes on the outside of the wall, ensuring the 'TOP' symbol is at the BOTTOM side of the flue. This will ensure a 2 degree fall for condensation to run TOWARDS the heater which is required ONLY for the through wall Vertical Co-axial flue installation. l.
VERTICAL THROUGH WALL FLUE INSTALLATION 8. Installing vertical section of ‘Through Wall’ Flue a.) Cut the black plastic spacer and fit into the ends of the horizontal flue pipe protruding through the outside wall. Cut off raised section and discard. Refit remaining spacer into end of flue pipe. b.) Fit the 2 x 45° bends as shown to the end of the flue protruding through the wall. c.) Fit condensate trap to 45° bend as shown with the 'UP' marking facing that way. d.
VERTICAL THROUGH WALL FLUE INSTALLATION Method • Use off-cut of Co-axial flue pipe. • Cut inner flue 170 mm long. • Cut outer flue 100 mm long. a.) Using an ESPIPE900, (or off-cut from ESPIPE900) cut the alloy inner pipe to 170mm in length and the outer plastic pipe to 100 mm in length. NOTE • Ensure flue is cut at the 'non socket' or free end of Co-axial flue pipe. • Flue off-cuts must be cut square and left with a smooth beveled edge.
SIDEWAYS HORIZONTAL FLUE INSTALLATION ‘Sideways Horizontal’ Flue Installation - (Page 4 - Option IV ) The sideways horizontal flue system is used to run Co-axial flue along the left or right hand side of the internal wall behind the heater. The flue pipes are clipped to the wall using the standoff clips supplied. It is possible to build a decorative cover around the flue pipe exposed inside the building. NOTE • The decorative cover is not part of this flue kit and is not covered by these instructions.
SIDEWAYS HORIZONTAL FLUE INSTALLATION • NOTE The ‘On Wall’ kit can run horizontally to the ‘left’ or to the ‘right’ at the rear of the heater as shown in the photo above. In a sideways horizontal flue system the positioning and direction of the condensate trap do not matter as no condensate will be collected and drained. Condensate drainage is ensured by the two degree ‘fall’ towards the terminal. Condensate trap must still be fitted as part of flue system.
SIDEWAYS HORIZONTAL FLUE INSTALLATION p.) Drill through the hole in the plastic cover plate and into metal air intake pipe. Secure with the stainless steel self-tapping screw supplied to lock the flue terminal in place. q.) Attach the plastic wall plate to the outer wall through the three countersunk holes moulded into the plastic wall plate using the screws supplied. The finished flue terminal assembly should look like the photo to the right.
DOWN & OUT FLUE INSTALLATION ‘Down & Out’ Flue Installation - (Page 4 - Option V ) The ‘Down and Out’ flue options allows the ‘On Wall’ kit and condensate trap to face downwards and the flue pipe to be run vertically down through a hole in the floor and then horizontally to a suitable location outside. Flue is not to terminate beneath the building. Flue must terminate in accordance with AS 5601 Figure 5.3.
DOWN & OUT FLUE INSTALLATION • Ground excavation is not recommended to meet clearance or space requirements unless there is sufficient drainage provision. NOTE d.) Mark the centre of the heater flue pipe on the rear wall (see photo). Centre line of appliance 567mm +/25mm 378m Floor level e.) Using the mounting brackets supplied, mount the ‘On Wall’ kit with so that the centre of the flue pipes aligns with the markings on the wall using the stand off clips supplied.
DOWN & OUT FLUE INSTALLATION NOTE • • • • Measure from socket end of pipe. Cut pipe and discard ‘free’ non socketed end. Cut end to be left smooth. Ground excavation is not recommended to meet clearance or space requirements unless there is sufficient drainage provision. A small amount of ‘O’ ring lubricant on rubber seals will assist assembly. j.) Assemble vertical ‘Down’ section of the flue with the STRAIGHT END of the ESPIPE900 fitted to the end of the condensate trap. k.
DOWN & OUT FLUE INSTALLATION g.) Centre plastic wall plate and fasten to wall with the screws provided. 'TOP' symbol of wall plate should be facing upwards to ensure a 2° fall toward the flue terminal is maintained to allow any condensation to drain away from the heater. “TOP” symbol to be aligned to the top of external wall plate to ensure 2° fall for condensation to run toward outlet of flue terminal h.
