INSTALLATION INSTRUCTIONS
THIS PRODUCT MUST BE INSTALLED AND SERVICED BY A PROFESSIONAL SERVICE
TECHNICIAN, QUALIFIED IN POOL HEATER INSTALLATION.
Waterco strongly recommends that all vents, pipes and exhaust systems be initially and
periodically tested for proper operation. This testing can be accomplished by using a hand-
held carbon monoxide meter and/or by consulting with a gas professional.
Pool heaters must be used in conjunction with carbon monoxide detectors installed near the
pool heater. The carbon monoxide detectors must be periodically inspected for proper operation
so as to insure continued safety. Broken or malfunctioning carbon monoxide detectors must be
replaced immediately.
HEATER DESCRIPTION
Figure 1 is a diagram of the heater showing how it operates. Precisely matched orifice plates
meter the air and gas into the mixer. The blower draws the air and gas through the mixer and
forces it into the burner’s flame holder. A sealed heat exchanger surrounds the flame holder,
discharging exhaust gases out the flue.
Five (5) cm PVC water piping connects directly to the manifold/ header on the heat exchanger
using 5 cm PVC slip unions provided with the heater. The outer manifold remains cool; no heat
sinks are required. A thermal regulator and an internal bypass regulate the water flow through
the heat exchanger to maintain the correct outlet temperature. The heater operator control
panel board assembly is located on top of the heater.
