Installing the

Diesel-Burner’s

Fuel Lines,

continued

4.  Install and tighten the appropriate fuel fittings into the Aqua-Hot’s Fuel Ports, as well  

 

as the two selected ports of the Fuel Filter; reference Figures 27, 28A, and 28B.

5.  Connect the 

Supply 

and 

Return 

lines to the Aqua-Hot’s fuel port connections;  

 

reference Figures 1 and 27.

6.  Cut the 

Supply 

line at the Fuel Filter mounting location and connect the Fuel Lines  

 

as illustrated in Figures 28A and 28B.

3.23   Overview and Installation of the Aqua-Hot’s Exhaust System

WARNING: 

The Aqua-Hot’s exhaust is 

hot 

and must be kept away from any heat  

 

 

sensitive material.  

DO NOT 

direct exhaust downward as a fire may result  

 

 

when parked in dry, grassy areas.  In addition, the exhaust must not  termi- 

 

 

nate beneath the vehicle or beneath an openable window or vent.  Refer to  

 

 

“Internal Combustion Engine Exhaust Pipe Termination” Section 3-4.3 in the  

 

 

RVIA Standards Manual for additional exhaust system information.

A.  The exhaust must be able to freely exit away from the vehicle without any 

 

obstructions.

B.  Run the Exhaust Pipe to the driver’s side of the vehicle and ensure that the exhaust  

 

fumes 

cannot 

enter into the passenger compartment.

NOTES:

 

1. 

The Exhaust System 

MUST NOT 

terminate beneath the vehicle.  Failure to  

 

 

conform will void the Aqua-Hot’s UL listing.

 

2. 

Angle the Exhaust Pipe towards the rear of the vehicle so that the exhaust 

 

 

fumes will naturally move away while the vehicle is in motion.

C. 

DO NOT 

terminate the Exhaust Pipe within the awning area of the Motorhome, if 

applicable.  Be sure to keep the exhaust away from the slideout areas.  Reference 

RVIA’s ANSI/NFPA 1192 Handbook for additional information.

D.  From the Aqua-Hot’s 1-1/2 inch (F) NPT Exhaust Port, use a 1-3/4 inch I.D. (Inside  

 

Diameter) Exhaust Pipe; reference Figure 29.

NOTES:

 

1. 

Be sure to use standard Automotive Type Exhaust piping and avoid bends, if  

 

 

possible.

 

2. 

The total length of Exhaust Pipe should not exceed 

12 feet

.  Should your 

 

 

particular application require more than 12 feet of Exhaust Pipe, please contact  

 

 

Vehicle  Systems’ Product Application Support Department at 1-800-685-4298 

 

 

for assistance.

 

3. 

A maximum of two 90° Exhaust Pipe bends is allowed.

E.  A condensation drain must be provided in the exhaust system.  This can be

 

accomplished by drilling a small hole (approximately 1/8 inch diameter) at the  

 

Exhaust Pipe’s lowest point (slightly sloping the Exhaust Pipe away from the   

 

Aqua-Hot will achieve the same results); reference Figure 29.

F.  Be sure to secure the end of the Exhaust Pipe to the vehicle with the proper Exhaust  

 

Hanger/support hardware.
