	WATER PIPING
	Always follow good piping practices. Observe minimum 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 boil-
	er 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
	Victory II boilers are equipped with a water circulating
	pump mounted to the return water connection on the
	boiler. This pump location is appropriate for most installa-
	tions. It may be desired and proper to locate this pump to
	the alternate pump location shown in Figure 15, especially
	when applied to larger systems using high-head pumps.
	When the pump is removed there is a 11/2" FPT tapping
Figure 11b.
	that the return pipe may be attached to.

3. Air Control System

Diaphragm type compression tank is used to control sys- tem pressure. It must be installed at the boiler or between boiler and supply main pump(s).
