AQUA PLUS indirect-fired water heaters — Product Manual

Water heater filling and start-up

The installation and water chemistry must meet the requirements below. Failure to comply could result in damage to the water heater, causing possible severe personal injury, death or substantial property damage.

Start-up checklist

❏❏Verify that T&P relief valve is properly installed and piped as directed in this manual and per local code requirements.

Boiler water restrictions

•Thoroughly flush the boiler system (without water heater con- nected) to remove sediment.

•The water heater heat exchanger can be damaged by build-up or corrosion due to sediment.

•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 sys- tems. Inhibited propylene glycol is recommended.

•Follow boiler manual instructions for antifreeze usage.

•Do not use automotive, ethylene glycol or petroleum-based antifreeze. Do not use any undiluted antifreeze.

Maximum boiler-side flow rate

•Select the boiler-side circulator carefully. The flow rate through the boiler side of the water heater must not exceed the values below. Higher flow rates could result in an input above the rating of the T&P valve.

•Models AQUA PLUS-32, 42 and 52 — do not exceed 12 GPM.

•Models AQUA PLUS-80 and 105 — do not exceed 16 GPM.

Filling the domestic water tank

1.Fill the domestic water tank with fresh water that meets the chemistry requirements above.

2.Do not exceed a fill pressure of 70 PSIG.

When the water supply pressure is higher than 70 PSIG, make sure that a pressure-reducing valve is installed on the cold water supply line to prevent leakage from the T&P relief valve. A thermal expansion tank is also required.

3. Vent the piping as necessary to remove any trapped air.

❏❏Verify that the DHW tank and boiler-side piping are complete and are filled with water and pres- surized.

❏❏Verify that all air has been bled from both domestic and boiler water systems.

❏❏Verify that cold and hot water lines are correctly connected to domestic water system.

❏❏Verify that supply and return piping from boiler is correctly connected to water heater.

❏❏Check all fittings and piping for leaks.

❏❏Verify that all wiring is installed correctly.

❏❏Set water heater thermostat according to system requirements. See “Water heater temperature ad- justment,” page 24.

❏❏Start boiler according to the Boiler Manual.

❏❏Verify that the boiler and water heater are operating correctly, per “Water heater temperature adjust- ment,” page 24.

❏❏Review the following sections with the homeowner or system operator:

•Water Heater Start-Up

•Adjusting Water Heater Temperature

•Water Heater Maintenance

Start-up and operation

1. Follow the “Start-up checklist,” page 23 to prepare for start-up.
