• Air Ducts must be installed in accordance with the
standards of the National Fire Protection Association
“Standards for Installation of Air Conditioning and
Ventilation Systems” (NFPA 90A), “Standard for
Installation of Residence Type Warm Air Heating and Air
Conditioning Systems” (NFPA 90B), these instructions,
and all applicable local codes.
• Install this unit only in a location and position as specifi ed
on page 7. This unit is designed only for outdoor
installations and should be located with consideration

specifi ed on page 8.
• Never test for gas leaks with an open fl ame. Use a
commercially available soap solution to check all
connections (See page 17).
• Consult Table 10 (page 25), and the rating plate for the
proper circulating air fl ow and temperature rise. It is
important that the duct system be designed to provide
the correct fl ow rates and external pressure rise. An
improperly designed duct system can result in nuisance
