Installation /Owner’s Manual 17
Ventilation Requirements
WARNING:
The completed installation must:
- Make sure there is sufficient intake of fresh air for combustion.
- Make sure the living space is completely isolated from the combustion system of the refrigerator.
- Make sure there is complete and unrestricted ventilation of the flue exhaust which, in gas mode, can produce carbon
monoxide. The breathing of carbon monoxide fumes can cause dizziness, nausea, or in extreme cases, death.
- Make sure the refrigerator is completely isolated from its heat generating components through the correct use of baffles and
panel construction.
Certified installation needs one lower intake vent and one upper exhaust vent. Install the upper exhaust vent either through the roof or
through the side wall of the vehicle exactly as written in this manual. Any other installation method voids both the certification and the
factory warranty of the refrigerator.
The bottom of the opening for the lower intake vent, which is also the service access door, must be even with or immediately below the
floor level. This allows any leaking propane gas to escape to the outside and not to collect at floor level.
While there are no maximum clearances specified for certification, the following maximum clearances are necessary for correct
refrigeration:
Bottom
0mm min.
0mm max.
Each Side
0mm min
3mm max.
Top
0mm min.
6mm max.
Rear
0mm min.
25mm max.
These clearances plus the lower and upper vents cause the natural air draft that is necessary for good refrigeration. Cooler air
comes in through the lower intake vent, goes up around the refrigerator coils where it removes the excess heat from the refrigerator
components, and goes out through the upper exhaust vent. If this air flow is blocked or decreased, the refrigerator will not cool
correctly.
