18.1 health &
safety
18.2 boiler
assembly
Care should be taken when handling or moving the boiler parts as they are extremely heavy and fragile.
Ensure sufficient persons are available to move and handle the parts. Protective footwear and gloves must
be worn. Be aware that individual boiler sections weigh approximately 150 Kg each.
18.2.1 assembling boiler body
Ensure nipples and nipple seatings are clean and free from any surface
rusting. Lightly clean as necessary using steel wool or emery cloth.
To aid the assembly of the boiler body it is suggested to consider to
position the boiler on 2Nr flat strips of steel (min 100mm wide) this will allow
the section to move more easily into the final mounted position (see fig. 1).
18.2.2
Insert woven glass fibre sealing rope into deep groove around the
periphery of one side of each section.
18.2.3
Position and support the rear section of the boiler.
Lightly coat the nipples and nipple seatings with Linseed oil jointing
compound or red lead jointing compound and insert nipples into seatings.
It is important to ensure that the nipples are carefully and accurately
centred.
Lightly drive nipples home using a mallet and a block of wood (see fig 1.).
Do not use a hammer on the nipples.
Ensure any splintered wood is removed from the sections and nipple bores
as the boiler is progressively built.
18.2.4
Clean and lightly coat the nipple seatings of an intermediate section with
jointing compound and offer up to the rear section (see fig 2.). Carefully
engage the nipples into the seatings and temporarily secure the sections one
to another by hammering using a mallet and a block of wood.
