Installation
Smith Boilers are designed for ease of installation in new construction or existing structures. Follow the instructions provided in the manual for efficient installation.

Optimal Performance
Ensure maximum thermal efficiency by utilizing the larger heat transfer surface and cast-in heat transfer pins. The integral flue gas collector enables quieter operation.

Trouble-free Maintenance
To ensure a longer service life, regularly access the boiler for service and maintenance as needed. Smith Boilers designs products with easy servicing in mind.

Return Temperature Stabilizer
Utilize the Return Temperature Stabilizer to prevent service calls and extend the boiler lifetime. It equalizes water temperatures to minimize stress and ensure optimal performance.

Ease of Installation

For new construction or existing structures, Smith Boilers has built generations of experience into saving time and effort during installation.

Efficiency [in both the short and long term]

Simplified installation and enduring performance are our hallmarks. When plans require an eye on value over time, and call for less hands-on operation and maintenance, Smith Boilers will get you there. Proven in decades past, proving it for decades to come.

Optimal Performance
Larger heat transfer surface and cast-in heat transfer pins allow for maximum thermal efficiency—during the course of its lifetime, the boiler pays for itself several times over. Additionally, our integral flue gas collector enables quieter operation.

Trouble-free Maintenance
Smith Boilers designs products with the needs of the contractor and end-user in mind. Easy access for service and maintenance provides a longer service life.

Design

[in keeping with your vision]

An architect or specifying engineer can’t control how effectively a boiler is assembled on site or how it will be maintained over time. That’s OK—Smith Boilers has done that for you.

1. Machined Feet
   Smith Boilers ship with their own steel floor rails that match section feet assembly; no need for shims or field adjustments. Sections are drawn together pair-by-pair to reduce stress for simplified, no-jack connection

2. Indestructible Port Connectors
   Precise sectional alignment accommodates graphite port connectors that permanently withstand exposure to flue gases and water pressure up to 80 psi, and any water pH factor

3. Heat Transfer Rods
   Deep sections and precision machining allow for the placement of heat transfer rods between sections to maximize thermal output

4. Continuous Seal/Integral Smokehood
   The exact alignment of the sections allows for a convenient continuous ceramic rope seal, as well as a cast-in smokehood in order to reduce the operational noise

Return Temperature Stabilizer

Preventing Service Calls & Extending Boiler Lifetime
Commercial applications cycle-off when a facility is unoccupied. Re- introducing cold water causes uneven boiler expansion/contraction. This material stress can lead to failure. Smith Boilers’s flexible iron in combination with our Return Temperature Stabilizer equalize water temperatures to minimize stress and extend boiler life.
