3. Remove the hose from the primary drain valve when draining is complete. 4. Remove the plugs, nipple, shut-off valve and any other piping unless they will remain for use in the system piping. 10 Domestic Piping SECTION IV - Domestic Piping General Piping Requirements • All plumbing must meet or exceed all local, state and national plumbing codes. • Use pipe dope or tape suitable for potable water. • Use isolation valves to isolate system components. • Install unions for easy removal of the ELI

Failure to install a heat exchanger could lead to premature failure of the outer tank and void any warranty claim. WARNING Radiant heating system piping should include a means of regulating the boiler return water. The return water temperature to the unit should be maintained at 130.F or higher. Failure to prevent low return water temperature to the unit could cause premature failure of the unit and it’s burner system resulting in severe personal injury, death or substantial property damage. Siz

WARNING Failure to apply pipe dope as detailed above can result in severe personal injury, death or substantial property damage. WARNING Use a two-wrench method of tightening gas piping near the unit and its gas valve. Use one wrench to prevent the gas valve line connection from turning and the second to tighten adjacent piping. Failure to support the gas valve connection piping could damage the valve and the gas line components. Fig. 15: Recommended Gas Supply Piping 28 Fuel Piping Pipe Sizing
