Introduction
Boiler is designed for use in closed heating systems where
all steam is returned as condensate and make-up water is
minimal. Boiler is not designed for or intended for use in
open systems using 100% make-up water.
Prior to Installation
• Verify correct boiler for type of gas being used
natural or propane. See Rating Plate.
• Verify boiler size and dimensions. See Figure 1 page 2.
• Verify ratings and capacity data for natural gas. See
Table 1 page 3.
Installation Requirements
• Supply boiler with correct gas (natural or propane),
fresh air for combustion, and suitable electrical supply.
• Connect boiler to adequate venting and piping
systems.
• Provide boiler with properly located and adjusted
thermostat.
Installation of boiler in building under construction, use
precaution to insure clean combustion air supply during
construction process. Airborne particulate from construction
materials can clog burner ports and cause incomplete
combustion and sooting.
Complete all steps for safe and proper heating system
operation.
