water heaters are highly efficient, low maintenance systems.
• Complete thermal exchange technology means no fuel is used for warm-up or idle time and no energy is lost through
conversion or exchange.

• Water conditioning is not required.
Common options:
• Gravity drain (without a transfer pump)
• Standard (consistent incoming water temperature) or modulating burner actuator
• Natural gas or propane fuel
• Remote or integral tank
Other available options include:
• Skid-packaged heaters
• Performance matched components
• Ultra-low NOx emissions
• Non-standard fuels
• Storage tank heating element
Peripheral components:
• Digital mixing valves
• Variable frequency drive pump
• Hose stations
Optional services:
• Turn-key installation
• Installation project management

The information in this manual generally uses
a 5 million Btu/hr unit and is intended to be typical. Illustrations are not intended to be complete or correct in every detail.
System-specific drawings, including wiring schematics, are provided with each unit and should be referred to when installing
and operating your system.
Note:
Armstrong provides separate IOMs for the burner, blower, and for optional components. Consult the appropriate document for
