12. Lift out and rotate the heat exchanger (12).
Make sure the insulation strips that were under
the header bars stay in position.
13. Rotate the conduit assembly and attach it to the
switch box (11). Tighten the compression nut on
the other end.
14. Reinstall the screws (10) through the hold-down
clips at each corner of the heat exchanger. Put
the insulation back in the corners.
15. Reinstall the drain extensions (8) and 1/4" plug
(9) in the positions shown in Figure. 5.
16. Straighten the siphon loop tubing (7) and install it
in the header at the original position of the 1/4"
drain plug (see Figure 5).
17. Remove the vent blades (13) from both gap
spacers. Reinstall the vent blades using the
previously unoccupied holes in each of the gap
spacers.
18. Replace the gap spacers (6) on the opposite side
of the heater from their original position.
19. Reinstall any previously removed rubber
grommets and replace siphon loop cover (5).
20. Replace the heat exchanger end baffles (4).
21. Reinstall the flue collector assembly (3).
22. Replace the top assembly and fasten it in place
with the eight screws (2) previously removed.
Install the inner stack
23. Reinstall the inner stack (1). Install the chimney
cap assembly, or barometric draft control if one
was removed.
5.5 Connections at Heater
Connect the inlet and outlet piping to the
universal flange couplings on the heater as shown in
Figure 12. The inlet and outlet ports on the heater are
clearly marked with arrows on top of the control
cover.
The flanged couplings accept either threaded iron
pipe, 1-1/2" NPT, unthreaded 1-1/4" iron pipe, or
1-1/2" copper tubing (see Fig. 12).
Connect the pool heater between the pump and
filter and the pool or spa. If the system flow rate
exceeds 60 gpm (227 lpm), install a manual bypass
valve between the heater inlet and outlet (see Figure
9). If the flow rate is below 60 gpm (227 lpm), the
automatic, built-in bypass valve will maintain the
proper flow through the heater.
If a manual bypass is required, see section 7.6 of
this manual for the proper procedure for adjustment.
Install a check valve and heat sink pipe in the
heater inlet if any part of the piping or filter system
uses plastic materials (see Figure 9).
