Installation Requirements
Cozy heat exchangers can be mounted in one of two
configurations: either flat on the ground, or vertically. Reference
Figure 64.
• Supply ventilation cross-sectional area of at least 29in
2
(74cm
2
) must be supplied to each heat exchanger.
• Do not supply heat exchangers air which is drawn from the
bay areas.
• Return air should be drawn from the same room the heat
exchanger is heating.
• The anti-freeze and water heating solution must flow in
through the bottom of the heat exchanger, and out the top
(reference Figure 77).
• The Aqua-Hot 125D is designed to work with up to 3
thermostatic heating zones.

AC Electric Connection
Connecting the Aqua-Hot to AC Power
The following section will detail how to connect the Aqua-
Hot to the vehicle’s AC electric system. Connect the 3-pin Molex
connector to the coach-side AC electric system in order to utilize
the Aqua-Hot’s AC heating element.
The Aqua-Hot utilizes Molex 19403 and 19045 series
connectors for the AC electrical circuit. These are self-contained
connectors which can be readily purchased from your choice
of electronics supplier. Listed below are three different mating
connections.

• Installation must be performed by a qualified professional
according to current national regulations. Reference
A119.2/NFPA 501C Standard on Recreational Vehicles
1993 Edition.
• The boiler must be connected to a 120V AC supply
permanently and be protected with a 20A breaker
(minimum). The 120V AC must be separate from 12V DC.
• It must be possible to disconnect the power to the boiler,
either an easily accessible plug or a circuit breaker.
• Please refer to the schematic on page 53.
