INSTALLATION MANUAL
This appliance is a gas-fired direct vent modulat-
3
ing cast aluminum hot water boiler. A revolutionary
4
cast aluminum monoblock heat exchanger means
4
better heat transfer and thermal storage than simi-
larly sized cast iron boilers, which results in higher
5
efficiency. The heating system water absorbs large
6
amounts of heat from the cast aluminum heat ex-
9
changer, cooling the flue gases and causing con-
densation. Sealed combustion, premix gas burner,
and low flame temperature means drastically re-
duced CO and NOx emissions, which contribute to
a cleaner and healthier environment.
This appliance, unlike normal residential atmo-
spheric and induced draft units, takes its combus-
tion air directly from the outdoors (sealed combus-
21
tion) and does not compete with building occupants
for fresh air. Sealed combustion (also known as
"direct vent") is the safest and best way to obtain
plenty of clean combustion air. The forced draft fan
draws in the outside combustion air to mix with gas,
which flows into the pre-mix burner and combusts.
The fan then forces the resulting flue gases from
the boiler unit and provides a positive removal of
the flue gases from the building through inexpen-
sive and readily available PVC and CPVC pipes.
