Mounting the Gas Header
Attention!
All lines/piping must be mounted free of tension. The weight of all the components should be supported
separately from the boiler so there is no force on the connections.
Attention!
During mounting of the gas header group, it is very important that the position of the support beam as well as
the support brackets of the headers allow for some play (tolerance) for a neat installation. After finishing the
installation, the support beam and brackets can be tightened.
1. Mount the support beam(s) for the hydraulic and gas header group loosely between the legs of the L-stands.
2. Mount the support brackets for the gas header at nominal height. See also Figure 7.2.
3. Place the gas header(s) on the support brackets and fasten it (them) loosely with the U-bolts. Make sure
that the connections for the corresponding connecting sets are at the upper side of the header(s).
4. Next mount the boilers on the frame. See chapter 10.
