Flame Guard^® Safety System

Recent changes in industry standards require that certain gas-fired water heaters feature Flammable Vapor Ignition Resistant (FVIR) technology, to prevent the ignition of flammable vapours. With over 4 billion hours of outstanding performance in the field and more than 800,000 installations in homes across North America, John Wood Flame Guard^® safety system gas water heaters are the only Flammable Vapour Ignition Resistant (FVIR) compliant water heaters on the market with more than five years of proven technology that you can trust.

With its patented TankSaver^® design and sacrificial magnesium anodes, the tank life of our John Wood indirect water heaters is significantly extended. Manufactured with a double-glassed main seam weld, factory-installed nipples and T&P valve, our indirect water heaters also feature a glass-lined coil that won’t lose heat transfer efficiency.

Extensive research and development by GSW engineers has resulted in the creation of an innovative new approach to atmospherically vented gas water heaters, the GSW Direct Vent water heater design. A proven performer with ten years of laboratory testing and field trials including nine winters in the extreme cold, the Direct Vent operates quietly with no need for an electric fan or external power supply. The balanced flue design with a side wall vent termination allows installation in locations without a chimney. The sealed combustion chamber and coaxial vent uses fresh air taken from outside rather then pre-heated air from within the home. Quiet, reliable and efficient operation in a quality design: the GSW Direct Vent water heater.

Polaris^® is the natural choice for quiet and efficient water and space heating or to meet large hot water demands. Our models are easy to install and service with full accessibility from the front.

The stainless steel tank with a submerged combustion chamber allows for quiet operation. Always flexible, power direct venting for our Polaris models is available using 2 or 3” PVC or CPVC pipe.

Polaris^™ – High-Efficiency Residential:

Technology that blends water heating and residential space heating into a single, super-high efficient water heating system.

Boasting super efficiency of 95%, our Polaris models are ideal for homes with higher water requirements. Polaris can also be used for forced air hydronic space heating with potable hot water, as well as radiant hydronic heating.

The Power Direct Vent is designed with a sealed combustion chamber, ultra quiet blower and state-of-the-art Robertshaw^® gas control for highly accurate temperature control. The Flamable Vapour Ignition Resistant (FVIR) design prevents flammable vapours from entering and igniting. All combustion air is brought in from outside – rather than heated air from indoors. The Power Direct Vent can be vented with 3″ ABS, PVC or CPVC up to 60′ horizontally through the wall or vertically through the roof.
