Another Space-Saving IdeaLochinvar’s technology not only makes our water heaters and boilers more efficient, it means they also have a smaller footprint. So they save space as well as operating costs.

And now there’s a way to get greater flexibility and reliability, save even more space, and get a system that’s perfectly matched to a facility–thanks to the use of a Stack Frame from Lochinvar.

Match Load And CapacityWith this versatile stand, you can stack almost any combination of our Armor®, Knight®, Copper-Fin®, Copper-Fin II®, Noble® and SolutionTM water heaters and boilers. So you can achieve the perfect Btu/hr capacity for each application.

For example, a facility needs a Copper-Fin II boiler with a total capacity of 1.6 million Btu/hr. Instead of installing an oversized CHN1802 unit or a smaller CHN1442 model, now you can combine two units – CHN992 and CHN652 models– to exactly match the facility’s needs.

Plus, the total footprint of this combined system is just over 10 inches wider than the CHN652 unit alone, making it smaller than either the CHN1802 or CHN1442 model. No Assembly Required

Lochinvar’s Stack Frame is fully factory assembled and shipped in one piece. The frame is welded using square steel tubing by certified welders ensuring integrity for the life of the frame.

Added System BenefitsThis modular design provides two other important benefits. First, it allows for system turndown for greater efficiency when demand is lower. Second, it ensures against system failure by utilizing two independent but complimentary units.For residential and light commercial needs or commercial applications of up to 4 million Btu/hr, the Stack Frame gives greater flexibility without a significant increase in stack size or overall system dimensions.

Once you’ve determined a facility’s requirements and the exact models needed, utilize the charts provided to calculate total system dimensions.

NOTE: Stack Frames are for indoor applications only.

Two Lochinvar 990,000 Btu/hr Copper-Fin II models stacked for a total capacity of almost 2 million Btu/hr.

Pre-Assembled Welded Construction – No Field Assembly Required

Stack Frame

Our compact Armor Commercial Water Heater (AWN151-286) requires even less space when stacked on a Stack Frame.
