11. If a header bolt is stripped in the process of
reassembly, drive it out of the header plate
and replace it (see Section 6, Parts List).
4F. Automatic Flow Control Valve
The automatic flow control valve has only one
moving part, normally requires no service, and will
withstand normal pool water for many years. Ex-
tremely high acid or chlorine concentration or hard
water could damage valve parts.
To determine if the valve is stuck open:
1. Shut off the filter pump.
2. Remove the flow control cap.
3. Make a visual inspection of the disc. If the
disc is not properly seated, or does not move
smoothly back and forth on the shaft, disas-
semble the valve and overhaul it
(see Fig. 29).
4. If parts are pitted due to corrosion by exces-
sive acid or chlorine in the pool water, they
should be replaced (see Section 6, Parts List).

This product must be installed and serviced by
a professional service technician, qualified in
pool and spa heater installation and
maintenance. Improper installation and/or
operation can cause nausea or asphyxiation
from carbon monoxide in flue gases which
could result in severe injury, property
damage, or death. Improper installation and/
or or operation will void the warranty.
When installing a new pool heater that will
connect to existing flueing, some adaptation of the flue
system will be required. This is due to variations in
flue centerlines with the replacement heaters. Refer to
the heater installation instructions for details of the
required flue system and appropriate standards.
5B. Installation Procedures
Zodiac Pool Systems, Inc., ships the LG heaters
with the low-profile top for an outdoor installation. To
install either the Jandy draught divertor (required on
all indoor installations) or the external flue terminal

1. Remove the top plate, stamped "HOT", by
slipping a fine-blade screwdriver into the slot
and prying it up (see Fig. 30).
2. Remove the top by removing all eight screws
connecting it to the jacket (see Fig. 31).
