RRGG- SERIES
;,_;; ;„ �•--F` Heats with gas, cools with electricity, provides year-

fy� ` . .
•= a COMPACT because all components are housed in a
single cabinet. The combination unit is completely
wired—with color coded wire—and factory assem-
bled. The units are completely dehydrated, charged
and tested before leaving the factory. Minimum field
work need be done—just connect the ducts, electri-
cal-gas supply and thermostat.
• CERTIFIED PERFORMANCE The design is certified
by the American Gas Association and Canadian Gas
Association for natural and L.P. (propane) gases. All
models carry the Air Conditioning and Refrigeration
Institute seal of certified capacity.
