Appendix A: Gas Pipe Escutcheon Installation and Analyzer Probe Location

APPENDIX A: GAS PIPE ESCUTCHEON INSTALLATION
Required Parts: P/N 467107, Gas Pipe Escutcheon (PVC), P/N 270114, Phillips Retention Screw (#8)
1. IMPORTANT! Turn off the electrical supply to the heater and turn off the pump.
WARNING! Risk of fire or explosion. Never test for gas leaks with an open flame.
The following escutcheon installation instructions are intended for new pool installations
only, not for retrofit purposes.
2. When installing the ¾" pipe into the gas valve, place the gas pipe escutcheon over the pipe so that the
larger circle is facing the heater's service panel and the smaller circle with the screw is facing away
for the heater service panel (toward the union) as shown in Figure 1.
3. Install the gas pipe as described in "GAS CONNECTIONS" on page 14.
4. Slide the escutcheon flush against the outside of the heater service panel and the gas pipe opening.
Be sure to completely cover large gas pipe opening in the panel to prevent rodents to gain access to
the inside of the heater.
5. Hand-tighten the retention screw to secure the escutcheon in place.
6. Safety check the gas pipe for leaks as instructed in GAS CONNECTIONS, PAGE 14, and BASIC
SYSTEM OPERATIONS, PAGE 32.
SERVICING: GAS COMBUSTION ANALYZER PROBE TESTING
A standard combustion analyzer probe will not fit in the openings in the top of the exhaust vent cover. The vents
have been reduced in size to limit rodent access. Do not force the probe in from the top of the exhaust vent cover,
use the 3/8-in hole on the lower right side of vent. See Figure 2.
