WATER PIPING

Always follow good piping practices. Observe minimum 25
mm (1") clearance to combustibles around all uninsulated
hot water pipes or when openings around pipes are not
protected by non-combustible materials.
On a hot water boiler installed above radiation level, the
boiler must be provided with a low water cutoff device at
the time of installation by the installer. (see Figure 15 for
piping arrangement)
1. Supply and Return
For tapping sizes see dimensions on page 2. Shut-off
valves are recommended.
2. Circulating Systems
When Victory II boilers are equipped with a water
circulating pump mounted to return the water into the
boiler, this pump location is appropriate for residences
of one or two stories. The alternate pump location
shown in Figure 15 is required in large, multi-story
building installations, especially when high-head pumps
are used.
3. Air Control System
Diaphragm type compression tank is used to control
system pressure. It must be installed at the boiler or
between boiler and supply main pump(s).
