Enclosure
The cabinet that encloses the refrigerator
is built by the RV manufacturer. Depending
on cabinet depth, height, and width certain
baffles may be present when cabinet
clearances exceed installation guidelines and
specifications.
Baffles
Baffles prevent hot air buildup “pocketing”
between the refrigerator cabinet and the
enclosure walls and/or ceiling. An enclosure may
be fitted with:

An absorber baffle and a condenser baffle

Side baffles

Vertical top baffle

Vertical angled baffles

Box baffle

Or a combination of any of the above.
Air Intake Vent
Ventilation and combustion air flow through the
air intake vent, which also serves as the service
access or door.
The air intake vent needs be kept clear of
obstructions that may restrict the flow of fresh air
into the enclosure. Figure 4-1 illustrates a typical
air intake vent installation.
Roof Exhaust Venting
In a roof exhaust venting warm air and
combustion gases flow out of the enclosure
through the roof exhaust vent. See Figure 4-1.
The vent has a non- removable metal mesh
screen to prevent leaves, birds, rodents and/or
debris from entering the enclosure.
Roof cap
The roof cap fits over exhaust vent. The sloped
end always faces the front of the RV. It is held
in place by four 2-1/2" long Phillips head screws.
