A2 Water heater piping  continued

Domestic water piping

Boiler water

•Union on domestic hot water outlet should be piped at a higher elevation than domestic water drain valve. This will make draining water heater easier.

•Install unions for easy removal of water heater. Use dielectric unions or couplings to protect hot and cold water fittings from corrosion when connecting dissimilar materials such as copper and galvanized iron pipe.

•If copper pipe is used for domestic water connections, first solder pipe to a threaded adapter, and then screw adapter into cold water inlet on top of water heater. Inlet contains an internal plastic dip tube rated at 230°F, which can be damaged by heat from soldering.

•When the supply pressure is higher than 70 psig, install a pressure reducing valve on cold water supply line to prevent water loss through T&P relief valve.

•If water heater will replace tankless coil in boiler,` disconnect piping to coil or remove coil from boiler and replace with a cover plate. Allow water to drain from coil. Do not plug tankless coil.

Plugging tankless coil inlet and outlet will result in severe personal injury, death or substantial property damage.

•Boiler water (including additives) must be practically non-toxic, having toxicity rating or class of 1, as listed in Clinical Toxicology of Commercial Products.

•If antifreeze is used in boiler system, local codes may require a backflow preventer on cold water supply line. Use antifreeze specifically intended for hydronic heating systems. Inhibited propylene glycol is recommended.

Do not use automotive, ethylene glycol or petroleum-based antifreeze. Do not use any undiluted antifreeze. This can cause severe personal injury, death or substantial property damage.
