Installation

R99 and R99I automatic air vent valves are usually installed

on each type of manifolds, at “high points” of the pipes

where an air pocket could form, on wall heating boilers or

ground-floor boilers, near unit heaters or heat exchangers.

The automatic air vent valves must be installed vertically,

with the plug facing upwards. The installation is advisable

in places that can be easily inspected.

WARNING. Close the cap of the air vent valve when rinsing out and filling

the system, to prevent impurities from entering the mechanisms of the valve

and damaging it.

 NOTE. It is possible combining a R160 shut-off valve in sizes 1/4”x3/8” and

1/4”x1/2”, to the automatic valve R99.

without emptying the system.

This combination (valve R99 + valve R160) can be also purchased and it is

distinguished by the product series R99I in sizes 3/8” and 1/2”.
