pipe. To assemble the inner stack, remove the tape
and small envelope from the sheet metal coil. Expand
the coil until the holes on each end are aligned. Use
the two screws supplied in the small envelope to
secure the ends together. Install the inner stack, 7"
(18cm) diameter, on the collar of the flue collector
before attaching the vent cap (outdoor installation) or
vent pipe (indoor installation) as shown in Fig. 4. The
XL-3 can be installed with the water connections on
either side. Water Pik Technologies ships the heater
with the water connections on the right side, but
changing the connections to the left side could simplify
the installation or improve access for service and
maintenance. Make the change before locating and
connecting the heater.
Follow these step-by-step instructions and
Figure 3 to reverse the heat exchanger:
1. Remove the control compartment door.
2. Remove the chimney cap assembly, or
barometric draft control if one is installed, and the
inner stack (1).
3. Remove the eight screws securing the top
assembly (2) and lift off.
4. Bend back retaining tabs and lift out the
wire guard (3). Take off the four V-baffles
(2 each side).
5. Lift out the flue collector assembly (4).
6. Remove the siphon loop cover (5) located on the
right side of the heater under the In-Out header.
7. Remove both gap spacers (6).
8. Disconnect the siphon loop on the header (7).
Remove both drain cocks (8) (one at each end of
the heat exchanger).
