Boiler base
The boiler base is to be constructed in accordance with the base
plans. The boiler block may stand on an iron frame set in
concrete but is not essential. The boiler must stand on a level
non-combustible base which is capable of adequately supporting
the weight of the boiler, water content and any ancillary
equipment. (Dimensions for optional TICO Sound reducing
framework shown opposite).
(Fig 2.2 & Fig 3.2 are for RU 2s
and Fig 2.3 & Fig 3.3 are for RU 3s).
Important Assembly Advice:
Please read through before starting the assembly!
The boiler is normally delivered in individual sections, which are
assembled on site as a boiler block using tapered nipples.
The individual weights of the boiler components are as follows:
Rear section
approx. 195kg
Intermediate section approx. 185kg
Front section with burner door approx. 285kg
Front section without burner door approx. 192kg
Burner door approx. 93kg
Flue gas collection housing approx. 39kg
NOTE: Weights for RU 2s (Fig 1.2) & RU 3s (Fig 1.3) are
shown in appendix at rear.
The watertight joint between two boiler sections is a high-
precision press fit between the boiler nipple and nipple port. The
block assembly must be carried out accordingly with precision.
The following points should be observed during assembly:
No damage to the nipple and borings should be apparent.
Before a nipple is inserted and a section fitted, the nipple and the
boring should be inspected. Any damage, e.g. to the face of the
boring, destroys the nipple seal and leads to leakage.
Attention! Slight damage (transport damage) to the faces of the
boiler nipple or to the nipple ports (A) can be corrected with a
small smoothing file and emery cloth without affecting the water
tightness of the joint.
−
The accompanying nipple jointing oil sealing compound
serves as a lubricant as well as a waterproof seal and
must be used.
−
During the assembly no dirt should be allowed to remain
on the nipples or in the boring. These should be inspected
during each assembly phase, but particularly before fixing
on the pulling-up flanges. Particles of dirt, which are not
removed, can lead to leakage.
−
During the boiler block assembly take care that the various
boiler sections are fitted to the various positions,
depending on the model.
−
Boiler nipples and nipple ports must align exactly at all
stages of the assembly. An inclined inserted nipple leads
to leakage.
In addition, certain specific points should be observed at each
stage.
