1.6. Transport and Storage
Please remove the packing materials and examine the
consignment for correctness, completeness and possible
transport damage. The equipment is to be transported and stored
only in its original packing. Interim storage of Hoval gas boilers
should only to take place in weather protected rooms and only in
the original packing. The ambient conditions for storage must be
within the following limits:
•
Air temperature: -10°C - 50°C
•
Air humidity: 50 - 85% relative humidity
•
No condensation
1.7. Installation. Location requirements
The installation site of the boiler cascade should allow proper
connection of the flue duct work to all the boilers in the cascade.
In addition, there should be adequate room for maintenance and
air circulation around the cascade of boilers.
The boiler cascade must be set up in a separate installation
room.
A floor standing boiler cascade must be installed on a flat, or level
fire proof floor.
All boilers must have a minimum clearance of 500mm at the front
for preventative maintenance and commissioning work to be
carried out.
