Handling Instructions
The PERFORMANCE PLUS is generally eas-
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.
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
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
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.
3. On the outlet flange of the circulator pipe
install a 1” NPT nipple and shut-off valve.
Use pipe dope sparingly to allow removal
of the fittings upon completion of the test.
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
c i r c u l a t o r.
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.
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.
