INSTALLATION INTO WALL CAVITY.
( TWIN SKIN FLUE )
METHOD A
THE MINIMUM WALL CAVITY REQUIRED IS 35 mm. SELECT A PAIR OF
STUDS IN FRONT OF WHICH THE HEATER IS TO BE INSTALLED. THE
GAP BETWEEN THE STUDS SHOULD BE NO LESS THAN 35 mm AND
NO GREATER THAN 610 mm. ENSURE CEILING AND ROOF MEMBERS
WILL NOT OBSTRUCT VERTICAL PATH OF FLUE.
METHOD.
1. CUT FLUE OPENING CENTRAL TO WALL STUDS IN THE WALL
CLADDING. ( SEE FIG 7. )
2. CUT AWAY TOP WALL PLATE AND ANY EXISTING NOGGINS
BETWEEN STUDS.
3. CUT CLEARANCE HOLE FOR 100 mm DIAMETER FLUE PIPE IN
THE ROOF.
4. FIT HEADER ASSEMBLY INTO FLUE OPENING LEAVING A 12 mm
GAP BETWEEN TOP OF THE HEADER ASSEMBLY AND WALL
CLADDING AS SHOWN.
5. DRILL 4 HOLES THROUGH HEADER FLANGES AT STUD CENTRES
AND USE CLOUTS OR SCREWS TO ATTACH TO WALL.
6. MEASURE DISTANCE FROM FLOOR TO TOP OF FLUE OUTLET OF
THE HEATER.
7. ADJUST ELBOW TO THE DISTANCE MEASURED PLUS
2 mm AND
TIGHTEN SCREW. ENSURE FLUE ELBOW IS HORIZONTAL.
8. BEND TABS IN AT THE BASE OF THE TWIN SKIN FLUE AND
LOWER TWIN SKIN FLUE DOWN THE WALL CAVITY.
9. SLIDE TOP PLATE FLUE SUPPORT OVER TWIN SKIN FLUE,
CENTRALISE AND NAIL TO THE TOP PLATE.
10. SLIDE FLUE ADAPTER INSIDE INNER SKIN AT TOP OF TWIN
SKIN FLUE.
11. FIT SMALL END OF THE 100 mm DIA FLUE PIPE INTO FLUE
ADAPTER. FIT FURTHER LENGTHS WITH SMALL END
DOWNWARD AS REQUIRED. (THE SMALL END HAS A SWAGE
35 mm FROM THE END.)
12. FLASH BETWEEN FLUE PIPE AND ROOF CLADDING USING
EITHER LEAD FLASHING OR AN APPROVED SILICON RUBBER
PIPE FLASHING BOOT.
13. FIT COWL TO THE TOP OF THE FLUE PIPE, ALIGN THE SCREW
HOLES AND FASTEN THE 3 SCREWS SUPPLIED.
