water to virtually eliminate radiant heat loss

from chamber

• Direct spark ignition

• Spiral heat exchanger keeps hot burner gases

swirling, uses centrifugal force to maximize

efﬁciency of heat transfer to water in tank

• Spiral heat exchanger reduces lime scale

from forming on water-side surfaces, which

maintains energy efﬁciency over time

• ASME Construction

POWERED ANODES STANDARD ON ALL

MODELS

• Provides long-lasting tank protection in varying

water conditions

• Powered anodes are non-sacriﬁcial

• Automatically adjusts output needed to

properly protect the tank

PERMAGLAS

coating technique to ensure uniform coating

• Heat exchanger coil is glassed both externally

and internally for optimum protection

MECHANICAL VENTING VERSATILITY

• Conventional power venting or direct venting

• Vents vertically or through a sidewall

• Front located exhaust and condensate

connections allow for easy install and access

terminate separately outside building or

through single opening, using concentric vent

assembly

• Canadian installations require ULC S636 PVC/

CPVC, ULC S636 Polypropylene and AL29-4C

stainless steel pipe for intake and exhaust

HIGH EFFICIENCY MODULATING
