High Performance Gas Fired Commercia l Pool Heaters

6/08 Part #P1-355

the Perfect Combination of Accurate Control,

Efficiency, and Long Life

MegaTherm
®
is packed with performance features designed specifically
for the commercial, institutional, and large residential pool market.
The primary/secondary pump and control (Models 500–1825) feature
an electronic controller with a solid state sensor and adjustable
differential for accurate temperature control. Inlet water is preheated
to eliminate condensation, and a constant velocity in the heat
exchanger increases tube life. The diverter valve has been eliminated
in the pool circulation line, resulting in lower installation and operating
costs. And, inlet and outlet thermometers with ±1% accuracy allow
precise set-up and temperature rise monitoring.

Additional Design Advantages Include:

• Control system includes automatic temperature control, temperature
limit, gas pressure regulator, redundant electric gas valve, water
flow sensing, electronic flame safety supervision and manual gas
shut-off valve. The standard control system operates on 24 VAC
with a 120 VAC power supply. Standard units are intermittent
(spark) ignition.
•Working pressure of 160 psi complies with Section IV of the ASME®
Boiler and Pressure Vessel Code. Units are registered with the
National Board of Boiler and Pressure Vessel Inspectors.
•
Pressure relief valve is ASME
®
rated and is selected to provide
discharge capacity in excess of unit heating input.
•
Combustion chamber is cast refractory with a 2000° F (1093° C)
working temperature.
• Burners are atmospheric type constructed of AISI alloy 430 (models
500–1825) or AISI 439 (models 2000–5000) stainless steel.
• Chassis and jacket parts are of galvanized steel meeting ASTM®
Standard for G90 coating. Exterior is finished with acrylic paint,
thermoset at 325° F (163° C).
•
Integral flow control valve on models 2000–5000 accepts flows
up to 300 GPM.
