INSTALLATION
1. The BTU output capacity of the furnace proposed for installation should be based
on a heat loss calculation made according to the manuals provided by the Air
Conditioning Contractors of America (ACCA) or the American Society of Heating,
Refrigeration and Air Conditioning Engineers, Inc. (ASHRAE).
2. This furnace is equipped with orifices sized for operation with natural gas. For
conversion to Propane Gas see instruction MG-814 in Gas Conversion Kit supplied
with furnace.
3. These Category Type IV furnaces are shipped completely assembled and wired
(internally). See the Dealer Receiving and Freight Claim Procedure Section of the
price guide for parts shortage or damage. The furnace and duct system must be
adjusted to obtain a temperature rise of 40°F to 70°F through the furnace after
installation. (See rating label located on separator panel inside the furnace
vestibule). The installation must conform with local codes, or in the absence of local
codes, with the National Fuel Gas Codes (ANSI Z223.1 or latest edition) and with
these instructions.
: This furnace is not to be used for temporary heating of buildings or
structures under construction.
Many of the chemicals used during construction, when burned, form acid bearing
condensate that can substantially reduce the life of the heat exchanger.

conjunction with any fossil fuel burning appliance. The CO alarm shall be installed
according to the alarm manufacturer’s installation instructions and be listed in
