Certification and Code Requirements
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 ventila-
tion 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.
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.
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.
exhaust vent. Install the upper exhaust vent either through the
roof or through the side wall of the vehicle exactly as written in

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.

American Gas Association/Canadian Gas Association (AGA/
CGA) certification allows the refrigerator to have zero (0) inch
minimum clearance at the sides, rear, top, and bottom. While
there are no maximum clearances specified for certification, the
following maximum clearances are necessary for correct
refrigeration:
CGA) certification allows the refrigerator to have zero (0) inch
minimum clearance at the sides, rear, top, and bottom. While
there are no maximum clearances specified for certification, the
following maximum clearances are necessary for correct
refrigeration:
Bottom
0 inch min.
0 inch max.
Each Side
0 inch min
1/8 inch max.
Top
0 inch min.
1/4 inch max.
Rear
0 inch min.
1 inch 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.
