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 Gas Modulation
Control (GMC)
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. Connect black
wire to a ground connection. The Red wire is positive (+)
and the Black wire is negative (-).
2. Determine location of the Gas Modulation Control
(GMC) Dial. Drill a 1-3/4" hole.
3. To install the remote Gas Modulation Control/GMC
(Figure 5), connect the GAS MOD Box wire from the Water
Heater to the White wire from the GMC and Black wire
from the GMC to any accessible Ground wire/Ground
connection of the vehicle. Be careful not to break wire
connections on back of dial.
