Specifications

In order to prevent property damage or injury,
ensure that the wiring is handled and routed
carefully so as not to cause any damage to it.
Additionally, be careful not to create any kinks in
the water pressure switch copper tubing when
handling the header.
CAUTION
An d'empêcher des dégâts matériels ou des
blessures, assurez-vous que le câblage est
manipulé et installé soigneusement de manière à
ne pas l’endommager. De plus, vous devez faire
attention à ne créer aucune imperfection dans la
conduite en cuivre de l’interrupteur de pression
d'eau en manipulant la tête.
ATTENTION
8. For an existing installation, remove the coupling
nuts from the header and disconnect the water
supply from the heater.
9. Remove the 10 bolts and washers from the inlet/
outlet header and remove the header from the tube
assembly.
10. Remove the 10 bolts and washers from the return
header and remove the header from the tube
assembly.
11. For an existing installation, remove the tube
gaskets and clean the header's mating surface of
any corrosion or debris. Replace the tube gaskets
with new ones. Do not use any metal tools on the
header surface. Scratches may compromise the
seal integrity.
12. Place the inlet/outlet header over the bolts and
gasketed tubes on the left side of the tube assembly.
Align the bolt and tube holes in the header with
the bolts and tubes in the header bar and slide the
assembly together. Refer to Figure 9.
NOTE Do not reverse the position of the bypass.
13. Thread on the 10 bolts and washers and hand
tighten.
14. Place the return header over the bolts and gasketed
tubes on the right side of the tube assembly. Align
the bolt and tube holes in the header with the bolts
and tubes in the header bar and slide the assembly
together.
15. Thread on the 10 bolts and washers and hand
tighten.
16. Use a torque wrench to tighten the bolts on each
header to 4 ft-lbs. The bolts must be tightened in
the sequence indicated in Figure 11.
4. Remove the return header side cover plates, top
and bottom. See Figure 10.
5. Disconnect the blue "HiLimit" two-pin connector
from the Power Interface board on the raceway.
Clip any wire ties attached to the harness. Feed
the "HiLimit" two-pin connector and wiring back
through the way it is routed to the header so that
the harness hangs free from the header, outside of
the cabinet.
6. Disconnect the two "WATER TEMP" temperature
sensor leads from the Power Interface board on the
raceway. Clip any wire ties attached to the harness.
Pull the wires out of the cabinet so that they hang
free from the header, outside of the cabinet.
7. Disconnect the yellow "Water Press" two-pin
connector from the Power Interface board on the
raceway. Clip any wire ties attached to the harness.
Feed the "Water Press" two-pin connector and
wiring back through the way it is routed to the
water pressure switch so that the harness hangs
free from the water pressure switch, outside of the
cabinet.
