Burner Connections
The burner comes pre-assembled, but the direction of the
supply or return connectors can be modified if needed.
Please reference the instructions below and the image in Figure
46.
• The O-rings must be clean and lubricated prior to installation
on the burner.
• Install the O-rings in place on the burner.
• Mount the connector housing in the retaining plate and
fasten with a 15mm self-tapping screw, torque to 5 lb-ft.
• Verify the inlet and outlet ports on the burner prior to
installing hoses. The correct direction of the coolant flow
must be determined. The heater has flow arrows on the top
(see Figure 47).
• Secure hose connections using hose clamps, tightened
with a torque of 40 lb-in.

Plumbing Requirements
The plumbing lines are how the fluid is transferred from the
Aqua-Hot to the burner and back to the Aqua-Hot to transport
heat to domestic water and to the interior of the RV.
Properly installing the coolant hoses to the Aqua-Hot from the
burner are integral to the correct and safe operation of the
heating system.
Reference the requirements below to ensure the plumbing lines
are properly installed.
• Hoses used in this installation must comply with SAE 20 R3
specifications.
• The plumbing hoses should avoid any bends or dips as
these can cause excess air in the lines, not allowing the
flow of coolant to properly flow.
• The hose clamps must be tightened with a torque of 40
lb-in.
• Reference the plumbing diagrams below for an example of
how the burner should be plumbed with the 125DN.
