2.2 Location
I:
This boiler/water heater is for indoor installation only.
II:
For service access to the Riello control box, condensate drain “U” trap, and gas
train, refer to the clearances indicated on the boiler/water heater rating plate. Note
that some jurisdictions may have their own clearance requirements. In such cases
refer to all applicable local codes.
III:
The boiler/water heater can be placed in a basement or utility room. It should not
be placed in an unconditioned area where the unit and condensation could be
subject to freezing temperatures.
IV:
For reduced installation cost, locate the boiler/water heater as close to an outside
wall as possible.
V:
Flue gases can be vented out directly through a wall, or in case of retrofit
installation, the flue gas duct can be extended into the existing chimney
.
VI:
Keep boiler/water heater area clear and free from combustible materials, gasoline,
flammable vapors and liquids.
VII:
Ensure that inlet to the blower is kept clear of any obstruction so that combustion
air can flow freely through to the air intake blower.
VIII:
A resilient pad to separate the boiler/water heater from floor IS NOT REQUIRED.
2.3 Relief
Valve
A pressure relief valve is supplied as standard equipment. The relief valve is extra protection
against damage that could be caused by excessive water pressure. Either, mal-functioning of
controls, or creation of steam pockets due to water stagnation in some parts of the coils, may cause
such excessive pressure. This latter condition could arise if one or both coils are not properly
purged.
The pressure relief valve should be connected to a suitable water drain. The drain pipe MUST
pitch down from the valve and its internal diameter should not be less than that of the relief valve.
The end of the drain line should not cause any restriction to the water flow, and should be
protected from freezing. There should not be any valve of any type installed between the pressure
relief valve and the end of the drain line. Similarly, there should not be any instrument installed
anywhere along the length of the drain valve, between the relief valve and the end of the drain line.
The relief valve is installed in vertical position and should remain in that position at all times.
