PLACING & FITTING THE BOILER

CONSIDER THE FOLLOWING

Prepare the Boiler for mounting on a non combustible surface. Determine the positions for the flow

and return pipes using the suspension bracket (see next page) or a suspension frame, if any. When

marking the holes, ensure that the suspension bracket or frame is level. Drill the holes for the flow

and return pipes if required then hook the heating boiler (the Boiler is Heavy see table on page 7.

To avoid injury consider the weight of the appliance) onto the bracket or place it upon the frame.

The Boiler must be level.

NON ROOM SEALED BOILERS Ventilation to BS6644 (2005) BS5440 (2000) IGE/UP/10 (ed 2)

SEE CURRENT REGULATIONS

ROOM SEALED BOILERS (Type C as defined by B.S 6644 2005 ) Installation in a boiler room.

The ventilation provided shall be adequate to ensure that the boiler room temperature meets the

requirements as follows: The air supplied for boiler room ventilation shall be such that the maxi-

mum temperatures within the boiler house shall be as per current regulations:

— 25 °C at floor level (or 100 mm above floor level);

— 32 °C at mid-level (1.5 m above floor level); and

— 40 °C at ceiling level (or 100 mm below ceiling level).

Ventilation shall not be less than 2 cm² free-area per kW of net heat input at high and at low level

or as current regulations.

Before mounting and installing the boiler the following connections should be considered:

 Flue gas system and the flue gas pipe connections Notes on page 11 &12

 Air supply system and connections

 Flow and return pipe connection

 Condensate and pressure relief valve drainage notes on page 6

 Power supply (preferably the power connection positioned above the boiler)

 Fire resistant mounting wall or structure

When using multiple SCB Boilers on a common flue, the flue should be in negative pres-

sure, if not contact Strebel for advice on a cascade system. SCB Boilers 60kw to 120kw use a

co-axial flue. Twin pipe flue utilises an adaptor at extra cost. Boilers 150 and 180kW use parallel

flues. i.e. one air inlet tube and one exhaust tube. All Boilers can be used in a room sealed applica-

tion or, if the boiler room or fitting space complies with the relevant ventilation requirements, boilers

can be non room sealed i.e. exhaust only, providing ventilation complies with current regulations.

See pages 9 and 10 for flue connection details. Install horizontal exhaust Flue parts with at

least 5.2% fall in the direction of the boiler (more than 5 centimetre for every linear me-

tre).

Determine the position of the flow and return pipes and condensate pipes. Use the included suspension brack-

et or a suspension frame (when supplied) for positioning While marking the holes, ensure that the suspension

bracket or frame is perpendicular and the boiler does not lean forward. If necessary adjust the position with

the adjusting bolts at the lower rear side of the back panel (see drawing next page). When the adjusting bolts

aren’t sufficient enough, shim the gap behind the bolts to get the boiler in position. The exact boiler position

lies between the boiler hanging level and hanging slightly backwards.

The boiler should not lean forward in the mounted position.

Lock the suspension bracket with the security cover before making any other connections to the

boiler. This security cover will prevent the boiler from falling off the bracket.

Don't use excessive force during the mounting of the boiler connections. Work safely
