and look for light on the floor or surrounding walls (this is best done in a dark room). If light appears out of
the boiler, reseal between the sections.
Boilers which were split for installation will need to be hydrostatic pressure tested in accordance with
Section IV of the ASME Boiler and Pressure Code at a pressure equal to 1-1/2 times the maximum
allowable pressure on the boiler nameplate.
Caution: Do not hydrostatically test the boiler with any controls installed. Damage to
controls can occur due to over pressure.
Warning: Do not leave boiler unattended during hydrostatic testing. Cold water fill could
expand as it warms causing excessive pressure, resulting in severe injury, death or substantial
property damage. Leaks, if found, must be repaired immediately. Failure to do so can damage
boiler, resulting in substantial property damage.
Boiler Trim Piping
1. Install the ¾” aquastat immersion well in upper right side tapping of the rear boiler section. Install the
temperature sensor all the way into the well until it hits bottom and fasten in place with the retaining
clip as provided.
2. Pipe in pressure relief valve with ¾” street elbow and with the ¾” x 3” nipple in upper left side of the
rear section. Relief valve discharge must be piped to a safe place of discharge. See system piping.
3. Pipe in boiler drain with ¾” coupling and the ¾” x 6” nipple in the lower left side rear section.
