prevent property damage from condensate spillage. The switch should be wired to the auxiliary device
proving switch terminals on the low voltage connection board.
Condensate from the Triumph SS will be slightly acidic, typically with a pH from 3 to 5. Install a neutralizing
filter if required by local codes. If the boiler is not supplied with acid condensate neutralizer, a siphon
loop must be fitted on the condensate drain in order to avoid flue gas leakage.
5.7 Safety relief valves (SRV)
See the operation instructions for more details on SRV
SRV need to be installed so that no significant loads are placed on the outlet. Testing and occasional
weeping can create condensate. Drip pan elbows are recommended to handle these issues during
installation. Safety valves are shipped loose because they are vital to safe operation and can be
damaged during transport.
SRV are installed to prevent operation of the boiler above maximum allowable working pressure. It is
good practice to manually open the safety relief valves on your boiler monthly. This is done by lifting and
releasing the handle provided on the valve. Refer to the maintenance section for details on use of these
valves.
5.8 SRV discharge piping
A discharge pipe shall be used. It’s internal cross sectional area shall be not less than the full area of the
valve outlet or of the total of the valve outlets discharged therein, shall be as short and straight as possible,
and so arranged as to avoid undue stress on the valve or valves. A union may be installed in the discharge
piping close to the valve outlet. When an elbow is placed on a safety or safety relief valve discharge pipe
it shall be located close to the valve outlet downstream of the union.
The discharge from safety relief valves shall be so arranged as to minimize the danger of scalding
attendants. The safety or safety relief valve discharge shall be piped away from the boiler to a safe point
of discharge, and there shall be provisions made for properly draining the piping. The size and
arrangement of discharge piping shall be independent of other discharge piping and such that any
pressure that may exist or develop will not reduce the relieving capacity of the relieving devices below
that required to protect the boiler.
The discharge piping should be supported so that loads (piping weights and dynamic forces during
operation) transmitted to the relief valves are minimized. The weight supported by the valve should not
exceed the weight of a short elbow and drip pan or comparable weight of a direct connected free hanging
discharge pipe. Installations requiring long discharge piping runs should not have those discharge piping
runs directly connected to the valve. The valve manufacturer should be consulted if the weight to be
