2.1 Introduction
• Boiler is certified in accordance with ANSI Z21.13
American National Standards Institute) and CSA
(Canadian Standards Association) 4.9.
• This appliance is a gas-fired direct vent modulating cast
aluminum hot water boiler.
• Cast aluminum monoblock heat exchanger allows better
heat transfer and thermal storage than similarly sized
cast iron boilers resulting in higher efficiency.
• The heating system water absorbs large amounts of
heat from the cast aluminum heat exchanger, cooling
flue gases and causing condensation.
• Sealed combustion, premix gas burner, and low flame
temperature means reduced CO and NOx emissions,
which contribute to cleaner and healthier environment.
• This appliance takes its combustion air directly from
outdoors (sealed combustion) and does not compete
with building occupants for fresh air.
2 - INTRODUCTION
• Sealed combustion (also known as “direct vent”)
is safest and best way to obtain plenty of clean
combustion air.
• Forced draft fan draws in outside combustion air, takes
cooler flue gases from boiler unit and provides positive
removal of flue gases from the building through readily
available PVC and CPVC pipes. Canada use ULC S636
Material.
• These low pressure gas-fired hot water boilers are
design certified by CSA International for use with
natural gas and propane gas.
• Boilers are constructed and hydrostatically tested
for maximum working pressure of 50 psig (pounds
per square inch gage) in accordance with A.S.M.E.
(American Society of Mechanical Engineers) Boiler and
Pressure Vessel Code Section IV Standards for heating
boilers.
