PVG & SCG

High Efficiency Direct Vent and Sealed Combustion Cast Iron Water Boilers

Unbeatable Efficiency & Value!

Burnham’s PVG & SCG boilers offer a unique combination of high efficiency and value to homeowners. Available in direct vent (PVG) or sealed combustion (SCG) both models utilize either 3 or 4-inch stainless steel vent pipe to direct the flue products out of the building. This eliminates the need to install a liner in an existing chimney – which is often a major expense when replacing an older boiler.

PVG and SCG series boilers are simple to install, and require very little service and maintenance –especially compared to higher-efficiency condensing boilers. This can save homeowners hundreds of dollars in up-front installation costs, as well as several hundred dollars a year in maintenance and tune-up’s. Factoring in installation, annual service, and fuel usage - over time the operating costs of the SCG and PVG may be well below those of condensing boilers. While low temperature radiant heat systems are becoming more popular in newer buildings, many still utilize baseboard heat, convectors, air handlers. & indirect water heaters - which generally require higher water temperatures. Cast iron boilers are the best choice for these applications. The PVG and SCG deliver the winning combination of efficiency and durability in high-temp heating applications.

Reliable Cast Iron Heat Exchanger

PVG & SCG boilers have rugged cast iron heat exchanger sections that are poured in Burnham’s own state-of-the-art foundry in Zanesville, Ohio. This means that Burnham is able to control the quality of this vital component from the time that it’s poured to the time that it’s installed and tested in the boiler. The heat exchanger itself is designed for efficiency. Round pins on the outside of the exchanger increase the surface area which increases heat transfer. Inside, dimpled waterways promote turbulence as water flows

through the castings. This helps to thoroughly mix cooler return water with the water inside the heat exchanger. As a result, PVG and SCG boilers are more resistant to thermal shock and condensation than other comparable boilers. Steel nipples are used to join sections together. This vital component is impervious to petroleum-based chemicals (like antifreeze) which can break down the rubber gaskets that are used by competitors.

A Better Burner Base Thick Insulation

The burner base in the PVG & SCG has been engineered to deliver on Burnham’s ongoing commitment to safety, reliability, and durability. Underneath it’s simple two piece design sits stainless steel burner tubes which are secured by lock-in burner slots. A 1/4” pilot tube provides an ample flow of gas which contributes to reliable burner performance. An isolated combustion area beneath

the burner tubes optimizes airflow and keeps floor temperatures low beneath the boiler. The combustion chamber itself is lined with thick 1” insulation on the sides and 1-1/2” insulation on the rear. This keeps the heat generated in combustion directed upward toward the heat exchanger, not out into the boiler jacket and surrounding area.

Safety Without Compromise

Burnham’s reputation for building safe products is an ongoing commitment that is taken very seriously. Many additional safety features have been built into the PVG & SCG.

•Blocked Vent Switch

Safely shuts the boiler down if a chimney or vent blockage is detected.

•Flame roll-out switch

If an internal flueway restriction is detected, this device will automatically stop the flow of gas to prevent combustion gases from seeping into the home.

•Concealed Controls

All boiler controls are safely hidden under the jacket to prevent damage & tampering.
