SAFETY REQUIREMENTS

Recognize safety information. This is the safety- alert symbolZ.l_. When you see this symbol on the furnace and in instructions manuals be alert to

the potential for personal injury.

Understand the signal words DANGER, WARNING, or CAUTION. These words are used with the safety-alert symbol. DANGER identifies the

most serious hazards, those that will result in severe personal injury or death. WARNING signifies a hazard that could result in personal injury or

death. CAuT__Nis used t_ identify unsafe practices that c_u_d resu_t in min_r pers_na_ injury _r pr_duct and pr__erty damage.

Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should

install, repair, or service heating equipment.

Untrained service personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be

performed by trained service personnel. When working on heating equipment, observe precautions in the literature, on tags, and on labels attached

to or shipped with the unit and other safety precautions that may apply.

Follow all safety codes. In the United States, follow all safety codes including the current edition National Fuel Gas Code (NFGC) ANSI

Z223.1-2002/NFPA No. 54-2002. In Canada, refer tothecurrent edition of the National Standard of Canada Natural Gas and Propane Installation

Code (NSCNGPIC) CSA B149.1-00. Wear safety glasses and work gloves. Have fire extinguisher available during start-up and adjustment

procedures and service calls.

These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances, these instructions

exceed certain local codes and ordinances, especially those that may not have kept up with changing residential construction practices. We require

these instructions as a minimum for a safe installation.

INSTALLER: Affix these instructions

on or adjacent to the furnace.

CONSUMER: Retain these

instructions for future reference.

CondensateDrain Trap This furnace removes both sensible and latent heat from the products of combustion. Removal of the latent heat results in condensation of the water vapor. The condensate is removed from the furnace through the drains in the plastic transition and the vent fitting. The drains connect to the externally mounted drain trap on the left or right side of the furnace.
