1.Close domestic water drain valve.

2.Open domestic water isolation valves for water heater.

3.Vent air from inner (domestic water) tank by opening nearest hot water faucet. Fill domestic water tank completely by allowing water to run until there is a constant flow of water.

4.Close hot water faucet.

•Inner tank must be completely filled and pressurized before pres- surizing outer tank.

•Never use water heater unless inner and outer tanks are completely filled with water.

1.Close boiler water drain valve at boiler water outlet of water heater.

For proper operation of the water heater, always leave vent cap unscrewed one full turn.

The boiler-side piping must be equipped with a diaphragm- or bladder- type expansion tank, NOT a closed-type expansion tank.

4.Follow instructions furnished with boiler to fill with water.

5.When tank is full, air will stop escaping, and air vent will close. If air vent does not seat properly (i.e., water leaks out), remove cap “A”. Briefly push in valve “B” (see above) and release it to clean valve seat. Screw cap “A” on completely, then unscrew one turn.

6.If antifreeze is used in boiler water, check concentration. Boiler water (including addi- tives) must be practically non-toxic, having a toxicity rating of Class 1, as listed in Clinical Toxicology of Commercial Products. Inhibited propylene glycol is recommended. Follow antifreeze manufacturer’s instructions.

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 if ignored.
