3. On the outlet flange of the circulator pipe

 

install a 1” NPT nipple and shut-off valve.

Handling Instructions

Use pipe dope sparingly to allow removal

ier to handle and maneuver once removed from

 

the shipping carton and pallet.

 

To remove the shipping carton and pallet:

a.Remove the shipping straps and open the top of the shipping carton to remove the wood shipment insert.

b.Lift the shipping carton over the unit to remove. If ceiling height is limited the carton maybe cut open using care not to damage the exterior jacket of the unit.

c.Remove the front burner hood to pre- vent damage prior to lifting the unit from the shipping pallet.

WARNING

When lifting or moving the unit do not use the burner or its components as a means of a handle. Hand-truck the unit from the rear only.

d.Discard all packing materials.

Hydrostatic Pressure Test

BEST PRACTICES

Prior to permanently connecting water, gas supply or electrical supply, perform a pressure hydrostatic test of the outer tank to ensure all piping connections were not damaged during shipment.

Hydrostatic Test Preparation

NOTICE

To avoid getting water onto the unit and/or surrounding area additional pip- ing from the shut-off to a catch bucket or drain may be required.

4.Connect a hose to the primary circuit drain valve located per Figure 45 page 68, Item 2 and connect the other end to a fresh water supply. Ensure the hose can be used as a drain hose upon completion of the test.

Hydrostatic Test Procedures

1.Open the shut-off valve installed on the outlet flange of the circulator.

2.Open the fresh water supply valve and then open slowly the primary circuit drain valve to fill the outer tank with water.

3.When the water within the outer tank reaches the shut-off on the primary supply, close the primary circuit drain valve.

4.Close the shut-off valve, on the top of the circulator.

5.Slowly reopen the primary circuit drain valve until the test pressure on the temper- ature / pressure gauge reaches 10 psig maximum. Close the primary circuit drain valve.

CAUTION

1.Mount the circulator on the supply pipe as shown in Figure 11 page 23.

2.Temporarily plug the primary return con- nections as shown in Figure 11 using a 1” NPT pipe plug. Use pipe dope sparingly to allow removal of the plugs upon comple- tion of the test.

To prevent damage to the inner tank the test pressure must not exceed 10 psig.

6.Allow the test pressure to remain for 10 minutes.
