WARNING:
Products of combustion must not be allowed
to enter the return air ductwork or the circulating
air supply. Failure to prevent products of
combustion from being circulated into the living
space can create potentially hazardous
conditions including carbon monoxide
poisoning that could result in personal injury
or death.
All return ductwork must be secured to the
furnace with sheet metal screws. For
installations in confined spaces, all return
ductwork must be adequately sealed and joints
must be taped. When return air is provided
through the bottom of the furnace, the joint
between the furnace and the return air plenum
must be air tight.
The floor or platform on which the furnace is
mounted must provide sound physical support
of the furnace with no gaps, cracks, or sagging
between the furnace and the floor or platform.
Return air and circulating air ductwork must
not be connected to any other heat producing
device such as a fireplace insert, stove, etc.
Doing so may result in fire, explosion, carbon
monoxide poisoning, personal injury, or
property damage.
For *RA installations: The return air ductwork may be
connected to any or all of the following: left side return, right
side return, or bottom return.
NOTE: Do not use the back
of the furnace for return air. Table 2 in the front of these
instructions, contains the airflow data for this furnace
model. Where maximum airflow is 1800 CFM or more, two
openings must be used for return air.
GAS SUPPLY AND PIPING
General
This furnace may be installed for either left or right side gas
entry. A typical gas service hookup is shown in Figure 22.
When making the gas connection provide clearance between
the gas supply line and the entry hole in the furnace casing
to avoid unwanted noise and/or damage to the furnace. All
gas piping must be installed in compliance with local
codes and utility regulations. Some local regulations
require the installation of a manual main shut-off valve and
ground joint union external to the furnace. The shut-off
valve should be readily accessible for service and/or
emergency use. Consult the local utility or gas supplier for
additional requirements regarding placement of the manual
main gas shut-off. In the absence of local codes the gas
line installation must comply with the latest edition of the
National Fuel Gas Code (ANSI Z223.1) or (CAN/CGA
B149.1 or .2) Installation Codes.
If desirable an 1/8 inch NPT tap must be installed in the
gas line to the unit for use when measuring the gas supply
pressure. The tap should be readily accessible for service
use. A drip leg should be installed in the vertical pipe run
to the unit. Table 5 lists gas flow capacities for standard
pipe sizes as a function of length in typical applications
based on nominal pressure drop in the line.
IMPORTANT NOTES:
1. Gas piping must not be run in or through air ducts,
chimneys, gas vents, elevator shafts, etc.
2. Compounds used on threaded joints of gas piping
must be resistant to the actions of liquefied
petroleum gases.
3. The main manual gas valve and main power disconnect
to the furnace must be properly labeled by the installer
in case emergency shutdown is required.
