3. Adjust the air temperature rise range to the midpoint or
slightly above. Low air temperature rise can cause low vent
gas temperature and potential for condensation problems.
4. Set the thermostat heat anticipator or cycle rate to reduce short
cycling.
Air for combustion must not be contaminated by halogen com-
pounds which include chlorides, fluorides, bromides, and iodides.
These compounds are found in many common home products such
as detergent, paint, glue, aerosol spray, bleach, cleaning solvent,
salt, and air freshener, and can cause corrosion of furnaces and
vents. Avoid using such products in the combustion-air supply.
Furnace use during construction of the building could cause the
furnace to be exposed to halogen compounds, causing premature
failure of the furnace or venting system due to corrosion.
Vent dampers on any appliance connected to the common vent can
cause condensation and corrosion in the venting system. Do not
use vent dampers on appliances common vented with this furnace.

ADDITIONAL VENTING REQUIREMENTS

A 4" round vent elbow is supplied with the furnace. A 5 inch or 6
inch vent connector maybe required for some model furnaces. A
field-supplied 4 inch to 5 inch or 4 inch to 6 inch sheet metal
increaser fitting is required when 5 inch or 6 inch vent connector
is used. See Fig. 34-46, Venting Orientation for approved vent
configurations.
NOTE: Vent connector length for connector sizing starts at
furnace vent elbow. The 4 inch vent elbow is shipped for upflow
configuration and may be rotated for other positions. Remove the
3 screws that secure vent elbow to furnace, rotate furnace vent
elbow to position desired, re-install screws. The factory-supplied
vent elbow does NOT count as part of the number of vent
connector elbows.
The vent connector can exit the door through one of 5 locations on
the door.

1. Attach the single wall vent connector to the furnace vent
elbow, and fasten the vent connector to the vent elbow with at
least two field-supplied, corrosion-resistant, sheet metal
screws located 180° apart.
2. Vent the furnace with the appropriate connector as shown in
Fig 34-46.
3. Orient the door to determine the correct location of the door
cutout to be removed.
4. Use aviation-type tin snips to remove the correct U-shaped
cut-out on door.
Personal injury can result form sharp metal edges, etc. Be
careful when removing parts. Gloves and safety glasses
should be worn when servicing equipment.
An accessory Vent Guard Kit, KGAVG0101DFG is REQUIRED
for downflow applications for use where the vent exits through the
lower portion of the furnace casing door. Refer to the Vent Guard
Kit Instructions for complete details.
The horizontal portion of the venting system shall maintain a
minimum of 1/4-in. upward slope per linear ft and it shall be
rigidly supported every 5 ft or less with metal hangers or straps to
ensure there is no movement after installation.

SIDEWALL VENTING

This furnace is not approved for direct sidewall horizontal venting
without the use of an add-on power venter.
In the U.S.: Per the NFGC, any listed power venter may be used,
when approved by the authority having jurisdiction.
In Canada: Only power venters approved by the appliance
manufacturer and where allowed by the authority having jurisdic-
tion may be used for sidewall venting.
