III. GENERAL INSTRUCTIONS AND CLEARANCES – READ BEFORE START OF
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-815 in Gas Conversion Kit provided
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  for  the  50  series  and  50°F  to  80°F  for  the  75  series.  (See  rating  label
located on separator panel inside the furnace vestibule).  The return air temperature
must  be  above  55°F  to  prevent  condensation  of  flue  products  in  the  primary  heat
exchanger. 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.

4.    It  is  recommended  that  a  commercially  available  CO  alarm  be  installed  in
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
accordance with the latest edition of the UL Standard for Single and Multiple Station
Carbon Monoxide Alarms, UL 2034, or the CSA International Standard, Residential
Carbon Monoxide Alarming Devises, CSA 6.19.

5. The installer shall be familiar with and comply with all codes and regulations
applicable to the installation of these heating appliances and related equipment. In
lieu of local codes, the installation shall be in accordance with the current provisions
of one or more of the following standards.

a. Federal Manufactured Home Constructions & Safety Standard (H.U.D. Total

24, Part 280.)
