The near boiler piping, that is the piping around the boiler,
must be considered as part of the boiler for proper water
level control, and to produce dry steam. Correct near boiler
piping is crucial to the proper operation of the boiler and
the heating system. Follow these recommendations carefully
1 Place boiler in selected location, as near chimney as
possible.
2. Install the pop safety valve, using the furnished 3/4"
coupling, into the 3/4' pipe nipple on the top of the boiler.
Make a discharge pipe, using 3/4' pipe (not furnished}
to carry the water or steam to a nearby drain. Do not
connect the discharge pipe directly to a drain but leave
an air gap. The downstream end of the discharge pipe
must be unthreaded. No shutoff of any description shall
be placed between the pop safety valve and the boiler,

or on discharge pipes between such safety valves and
the atmosphere. Installation of the pop safety valve shall
conform to the requirements of the ANSI/ASME Boiler and
Pressure Vessel Code, Section IMThe manufacturer is not
responsible for any water damage
This boiler is equipped with two 2V2' supply connections
and two 2V2" return connections, one each on both the
left and right sides of the boiler. Unused connections must
be plugged with the 2V2" plugs (furnished}
Recommended near boiler piping for gravity return
systems is shown in Figure 5. This configuration uses one
supply and one return tapping. This setup can be used
on any size boiler in this series. The supply and return
connections may be piped both into the same side (either
left or right} or one into each side of the boiler.
