Site conditions will dictate the best method of assembling the Vertical Balanced Flue.
The following illustrations show boilers up against a rear wall as an example. It is not essential for the boiler to
be positioned this way. As long as the joists are capable of supporting the flue via the support plate supplied
in the Kit or the Flue support quadrant kit (optional).
The vertical flue kit is telescopic to allow for various ceiling heights.
To increase the height additional 1000 or 500mm extensions can be added up to the maximum number
indicated.
To reduce/adjust the height push the section down to the desired height and lock in place using the screws
provided.
IMPORTANT WARNING
Where a flue system passes through a joist frame, it is essential that the integrity of the ceilings’ fire barrier is
retained. This can be achieved by ALWAYS using the support plate and firestop ceiling trim.
We would also recommend strongly the use of the Adjustable Joist Sleeve (optional) to complete the fire stop.
A
lternatively this can be achieved by following the requirements of Section J of the current Building
Regulations.
NOTE:-
1. Joints in the Flue Pipe must not be situated with the joist space.
2. Joints in the Flue Pipe must be a minimum of 150mm below the ceiling
Pitched Roof Assembly Procedure:
Generally where conditions allow, the simplest assembly procedure is as follows:-
1. Position the Boiler, check water connections are possible.
2. Mark Flue position on ceiling.
3. Move Boiler away from position and cut the ceiling neatly, keeping the opening size in the plaster board as
close to the round Ducts of the Flue Terminal as practicable (say 10mm all round).
4. Cut the opening in the roof, allowing more than 50mm clearance on all sides from the timber joists.
5. Create 3-4 sided timber framed box for the Support Plate (S).
6. Bolt Joist Sleeve (R) (optional) to Support Plate (S) and screw onto timber frame.
7. Cut opening in the pitched roof allowing more than 50mm clearance on all sides from timber.
8. Remove the top rear panel of the boiler and fit the appropriate blanking plate to the rear panel using the
nuts and washers provided.
9. Fit the boiler offtake gasket to the four studs and clamp it in place with the vertical offtake spigot with the
four nuts and washers provided. Ensure the combustion test point screw remains accessible.
10. Ensure the flue exhaust seal is in position and undamaged.
11. Fit the vertical flue plate to the rear top panel of the boiler and fit the assembly into position over the
vertical offtake spigot.
