i - introduction

This appliance is a gas-fired direct vent modulating cast aluminum
hot water boiler. A revolutionary cast aluminum monoblock heat
exchanger means better heat transfer and thermal storage than
similarly sized cast iron boilers, which results in higher efficiency.
The heating system water absorbs large amounts of heat from the
cast aluminum heat exchanger, cooling the flue gases and causing
condensation. Sealed combustion, premix gas burner, and low flame
temperature means drastically reduced CO and NOx emissions,
which contribute to a cleaner and healthier environment.
This appliance, unlike normal residential atmospheric and induced
draft units, takes its combustion air directly from the outdoors
(sealed combustion) 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 burns. 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 inexpensive and
readily available PVC and CPVC pipes. ULC S636 Material must be
used in Canada.
Keep this manual near boiler and retain for future
reference.
