STREBEL CIS BOILERS
BOILER INSTALLATION INSTRUCTIONS FOR STREBEL CISM BOILERS

INSTALLATION INSTRUCTIONS

General Instructions:

The STREBEL CIS & CIS boilers are special boilers for light oil or gas­fired (forced) burners. They can be fitted in hot water heating
installations or low pressure steam installations, depending on the type.

Operating Conditions:

Hot water Heating installations boiler type STREBEL CIS
STREBEL CISM

Maximum high limit temperature 110ºC
Maximum Operating Temperature 95°C
Maximum working pressure 4 bar

Please note all relevant instructions when assembling the boilers.

The Installation: The connecting and initial setting in operation should
be carried out by a qualified heating specialist.
The boiler base is to be constructed in accordance with our diagrams.

Advantages of the STREBEL CIS AND CISM:

1. Long life of cast iron boiler body.

2. High efficiency of operation. Efficiency of combustion is higher
than 90.5 % for all kinds of fuels.

3. Possibility of delivery with burner.

4. Modern design.

5. Signalling of operation and defect of boiler.

6. It is possible to order a special variation of the boiler allowing a
water temperature of 115ºC (standard delivery is with boiler
water temperature up to 95ºC).

7. The ability to use a modular arrangement of connection.

8. Delivery fully assembled or in part form according to customer
requirements is available.

9. Door can be mounted to swing from either side (must be
specified in order).

10. Easily visible sight glass for viewing flame or for reading
combustion chamber pressure.

ASSEMBLY TOOL

A bar Pulling up tool, which is returnable after assembly has been successfully
completed, is made available for assembling the boiler block.
The complete pulling up kit CIS/CISM consists of the following:

1) Pulling up flange at the top rear section

1) Pulling up flange at the bottom rear section

1) Pulling up flange at the intermediate section

1) Pulling up flange at the bottom front section

4) Pulling up flange at the top front section

5) Pulling up piping

2.1) Basic bar

2.2) Extension

2.3) End piece

Case containing press tool

3.1) Free running ratchet spanner

3.2) Stop pins

3.3) Pulling up nut with thrust bearing
Items needed for construction: flat chisel, mallet, brush, small round smoothing
file, emery cloth, cleanser (e.g. petroleum), inspection lamp, spanner.

Advice on the use of the pulling-up tools.

1) The pulling up flanges at the rear section are screwed onto the boiler flow
and return connections.

2) The basic bars are inserted through the openings of the press flanges and
ports so that the screw ends are situated out of the ports at the front. (The
basic bars can be extended, as necessary.)

3) The pulling up flanges at the intermediate section or front section are pushed
over the basic bar screw end from the front.

4) The Stop pins are inserted at the back through one of the transverse borings
of the pulling up bar.

5) The pulling up nuts are screwed onto the basic bar screw end, from the front
until they take up the slack on the pulling up tool flanges.

6) The free-running ratchet spanners are put on the starting nuts.

Boiler base

The boiler base is to be constructed in accordance with our base plans. The boiler
block may stand on an iron frame set in concrete. The boiler base must stand on a
level, non combustable base which is capable of supporting the weight of the
boiler, water content and any ancillary equipment. These dimensions provide a
50mm excess around the boiler jackets.
