FOREWORD

The Advanced Modular (AM) Series P o o l H e a t i n g s y s t e m represents the latest in high
efficiency pool heating applications. The AM Series Pool Heaters are comprised of an AERCO
AM Series boiler, shell and tube heat exchanger, pump, expansion tank, air vent, and fittings for
makeup water connections, all factory configured and installed on a skid. The AM Series boiler
used in these systems features a unique modular design that provides exceptional reliability,
serviceability, and fuel savings from 399 to 1000 MBTU. Each boiler is comprised of between
two and four independent thermal modules firing up to 250 MBTU, and as low as 50 MBTU. This
allows for superior temperature control and low-cycling operation. High efficiencies and low vent
temperatures mean the unit can be vented in PVC, CPVC, Polypropylene, and AL29-4C vent
materials. The front-access design of the boiler also means the unit is very simple to maintain and
service.

AM Series Pool Heater Features:
•
Circulation pump: the pump circulates water through the piping loop, as well as the boiler and
heat exchanger.
•
Low Water Cut-Off: An LWCO is provided to prevent boiler operation in case of insufficient
boiler water flow.
•
Expansion tank: A rugged diaphragm type expansion tank protects the boiler water piping loop
from excessive pressure and keep the pressure below relief valve setting.
•
Air vent: The boiler is provided with an air vent to automatically purge the unwanted air in the
closed boiler water loop.
•
Makeup water connections: Connections are provided for the inlet of makeup water to the
boiler water loop for fast fill and to contain the pressure reducing fill valve, as well as the shutoff
valve.
•
Factory Configuration: All components are piped together and secured to a carbon steel
support base for ease of handling and installation.
