Vitorond 200, VD2 Series 320 to 1080 Installation
All necessary parts to assemble the heating boiler are
packaged and shipped in the carton labeled "Boiler
Accessories".
The heat exchanger block consists of a rear section with
mounted flue gas collar, a front section with mounted
combustion chamber door, and depending on the size
of the boiler, the appropriate number of intermediate
sections.
Individual cast iron sections are sealed by inserting
glass fiber rope gaskets which are glued into the pre-
cast groove system on each section to seal the flue gas
passageways.
The water side seal between the sections is achieved with
cast iron push nipples.
IMPORTANT
Observe directional arrows on cast iron sections. See Fig.
3, as well as step 7 on the following page.
