Benef i ts that make it last. ..
• Maximum Heat Exchanger Performance
- Durable cast Iron primary heat exchanger extends product life -it is
not uncommon for cast iron boilers to last in excess of 40 years.
- Corrosion resistant stainless steel condensing secondary heat exchanger, Increases efficiency
up to 5% by recouping heat energy from exhaust normally wasted when vented from the building.
• Reliable Boiler Design
-Unlike most high efficiency boilers in the industr)( the WM GV90+ has extra-wide waterways (over 2")
allowing sludge and debris, often present in older systems, to flow through easily. This limits
scale build up, which reduces boiler efficiency, performance and can lead to premature boiler failure.
-Down-fired, counterflow boiler design improves boiler efficiency The GV90+ offers (5) pass design in
the primary heat exchanger and (2) pass design in the secondary heat exchanger maximizing heat
transfer and optimizing boiler efficiency.
• Smart Circulator Strategy
-Built-in dual circulator strategy provides boiler protection- it can accept low return water temperatures
(down to 60° F) with no additional mixing valves, pumps, wiring and installation labor- a savings of over $500.
-The lower water temperature also allows homeowners the flexibility to add radiant heating for kitchens,
baths or other living spaces without the added cost of special return temperature controls.
• Proven Control Strategy
-The control platform features error-proof, labeled, snap in connections. Tested at over 100,000 cycles,
and boasting a failure rate of less than 1% over 20 years, it is sure to provide years of worry-free operation.
- Unlike traditional cast iron boilers, the GV90+ offers a unique control design allowing easy integration of
outdoor reset to take advantage of low water temperatures and improve overall system energy cost savings.
Benefits that conserve ...
• Exceeds Energy Star requirements with efficiency up to 92%
• Boiler sections made from recycled metals
• Lower emission levels than most boilers
... the GV90+ is one of the greenest cast iron boilers on the market

• Eligible for most utility rebate programs- check you r local area for details and c urrent rebate am ounts.
• GV90+ is the first cast iron gas boiler vented with PVC- saving 90% over the cost
of stainless steel venting material per foot
• Simple diagnostics significantly reduces troubleshooting time by using flashing LED
lights to communicate errors - no need to decipher codes or read lengthy manuals . liiil
