not less than 18 inches (457 mm) above the floor. Protect
the furnace from physical damage by vehicles.
• If the furnace is installed horizontally, the furnace access
doors must be vertical so that the burners fire horizontally
into the heat exchanger. Do not install the unit with the
access doors on the "up/top" or "down/bottom" side of
the furnace.

LEARANCES AND CCESSIBILITY
Installations must adhere to the clearances to combustible mate-
rials to which this furnace has been design certified. The mini-
mum clearance information for this furnace is provided on the unit's
clearance label. These clearances must be permanently main-
tained. Clearances must also accommodate an installation's gas,
electrical, and drain trap and drain line connections. If the alternate
vent/flue connections are used additional clearance must be pro-
vided to accommodate these connections. Refer to Section IX,
Vent Flue Pipe and Combustion Air Pipe for details. NOTE: In
addition to the required clearances to combustible materials, a
minimum of 24 inches service clearance must be available in front
of the unit.

Upflow
A furnace installed in a confined space (i.e., a closet or utility room)
must have two ventilation openings with a total minimum free area
of 0.25 square inches per 1,000 BTU/hr of furnace input rating.
Refer to the Specification Sheet applicable to your model* for mini-
mum clearances to combustible surfaces. One of the ventilation open-
ings must be within 12 inches of the top; the other opening must be
within 12 inches of the bottom of the confined space. In a typical con-
struction, the clearance between the door and door frame is usually
adequate to satisfy this ventilation requirement.

If suspending the furnace from rafters or joists, use 3/8" threaded rod
and 2"x2"x1/8" angle iron as shown below. The length of rod will de-
pend on the application and the clearances necessary.

XISTING URNACE
NOTE: When an existing furnace is removed from a venting system
serving other appliances, the venting system may be too large to prop-
erly vent the remaining attached appliances.
The following vent testing procedure is reproduced from the American Na-
tional Standard/National Standard of Canada for Gas-Fired Central Fur-
naces ANSI Z21.47·CSA-2.3 Section 1.23.1.
The following steps shall be followed with each appliance connected to the
venting system placed in operation, while any other appliances con-
nected to the venting system are not in operation:
a. Seal any unused openings in the venting system;
b. Inspect the venting system for proper size and horizontal pitch, as
required by the National Fuel Gas Code, ANSI Z223.1 or the CSA
B149.1-05 Installation Codes and these instructions. Determine that
there is no blockage or restriction, leakage, corrosion and other defi-
ciencies which could cause an unsafe condition;
c. In so far as practical, close all building doors and windows and all
doors between the space in which the appliance(s) connected to the
venting system are located and other spaces of the building. Turn on
clothes dryers and any appliance not connected to the venting sys-
tem. Turn on any exhaust fans, such as range hoods and bathroom
exhausts, so they shall operate at maximum speed. Do not operate a
summer exhaust fan. Close fireplace dampers;
d. Follow the lighting instructions. Place the appliance being inspected
SIDE
in operation. Adjust thermostat so appliance shall operate continu-
ously;
e. Test for draft hood equipped spillage at the draft hood relief opening
after 5 minutes of main burner operation. Use the flame of a match
or candle;
f. After it has been determined that each appliance connected to the
venting system properly vents when tested as outlined above, re-
turn doors, windows, exhaust fans, fireplace dampers and any other
gas burning appliance to their previous conditions of use;
g. If improper venting is observed during any of the above tests, the
common venting system must be corrected.
Corrections must be in accordance with the latest edition of the Na-
tional Fuel Gas Code ANSI Z223.1 and/or CSA B149.1-05 Installation
Codes.
If resizing is required on any portion of the venting system, use the
appropriate table in Appendix G in the latest edition of the National
Fuel Gas Code ANSI Z223.1 and/or CSA B149.1-05 Installation
Codes.

HERMOSTAT
The thermostat should be placed approximately five feet from the
floor on a vibration-free, inside wall in an area having good air
circulation. Do not install the thermostat where it may be influ-
enced by any of the following:
•
Drafts, or dead spots behind doors, in corners, or under
cabinets.
•
Hot or cold air from registers.
•
Radiant heat from the sun.
•
Light fixtures or other appliances.
•
Radiant heat from a fireplace.
•
Concealed hot or cold water pipes, or chimneys.
•
Unconditioned areas behind the thermostat, such as an
outside wall.
