The coach vent system must be able to provide
a way to direct the hot air, produced by the
action of the cooling unit, out away from the
installation of the refrigerator.
(23)
In a good installation there should be as little
open space as possible surrounding the sides
and top of the refrigerator to achieve proper air
flow. All potential dead air pockets should be
blocked or baffled to insure that heat from the
cooling unit won’t be trapped in these spaces
and reduce efficiency. In addition, the cooling
unit should be at least one inch from the
nearest surface made of combustible materials.
Please follow the installation manual for proper
dimensions and clearances.
RVIA requires that the refrigerator be
installed in such a manner as to provide
complete separation of the combustion system
and the interior atmosphere of the recreational
vehicle. This regulation requires all seams and
joints in the enclosure be sealed. The under-
counter installation is different. The addition of
a metal chute the width of the enclosure, that
extends from the upper side vent, will help
eliminate the possibility of dead air pockets. It
helps direct the hot air out the exhaust vent.
The best method for venting the absorption
refrigerator is with a lower side vent and a roof
vent. Using proper Dometic vents will give you
sufficient intake and exhaust areas for ventila-
tion

Heat application to the boiler section of the
cooling unit must be within the designed BTU’s.
Never oversize the heating element on AC or
DC power source. Always use the proper size
orifice for gas modes. As explained earlier, any
deviation will cause a potential cooling unit
failure.
