B: Installation of water heater with integral flange
1. Protect the side wall with masking tape or other suitable means to insure that
it is not damaged while installing the water heater.
2. Position the water heater so that the front edge extends from the opening
approximately 2" and insert the door flange into the housing.
3. Permanently attach the flange to the housing using stainless steel screws or
stainless steel rivets with recommended grip range of .188" to .129" and hole
size of .129" to .133".
4. To prevent water leaks apply a good amount of caulking or butyl tape on the
sidewall around perimeter of the opening that will be covered by the flange
and along the front edge of the housing that will contact the mounting frame.
5. Slide the water heater in place into the opening and press the door flange
against the sidewall.
6. Secure water heater housing unit to the vehicle using No.8 – ¾" flat head
screws through each hole in the door flange (Figure 4). Verify that a tight seal
exists between the side wall and the flange. If not, repeat above steps.
C: Installation of 12VDC Power and Mode Switch
1. SET THE POWER SWITCH TO THE "OFF" POSITION and
connect the power wires to a 12VDC circuit from the
DC panel protected with a 10 amp fuse. The Red wire is
positive (+) and the Black wire is negative (-) and is
internally connected to ground.
2. To install the remote Mode Switch (Figure 5), connect one
pole of the switch to the High/Low wire (green) and the other pole
to ground.
