LOCATION REQUIREMENTS & CONSIDERATIONS

•If the furnace is used in connection with a cooling coil unit, install the furnace upstream or in parallel with the cooling coil unit. Premature heat exchanger failure will result if the cooling unit is placed ahead of the furnace.

•If the furnace is installed in a residential garage, position the furnace so that the burners and ignition source are located not less than 18 inches (457 mm) above the floor. Protect the furnace from physical damage by vehicles.

•If the furnace is installed horizontally, ensure the access doors are not on the “up/top” or “down/bottom” side of the furnace.

•Do not connect this furnace to a chimney flue that serves a separate appliance designed to burn solid fuel.

•On Counterflow Installations, the air conditioning coil must bedownstreamonthesupply(positive)sideofthefurnace heat exchanger.

•Counterflow Installation over a noncombustible floor. Beforesettingthefurnaceovertheplenumopening,ensure the surface around the opening is smooth and level. A tight seal should be made between the furnace base and floor by using a silicone rubber caulking compound or cement grout.

•Counterflow Installation over a combustible floor. If installation over a combustible floor becomes necessary, use an accessory subbase (see Specification Sheet applicable for your model for details.) Aspecial accessory subbase must be used for upright counterflow unit installationsoveranycombustiblematerialincludingwood. Refertosubbaseinstructionsforinstallationdetails.Follow the instructions with the subbase for proper installation. Do not install the furnace directly on carpeting, tile, or other combustible material other than wood flooring. (NOTE: The subbase will not be required if an air conditioning coil is installed between the supply air opening on the furnace and the floor.)

CLEARANCESANDACCESSIBILITY

Installations must adhere to the clearances to combustible mate- rials to which this furnace has been design certified. The minimum clearance information for this furnace is provided on the unit’s clear- ance label. These clearances must be permanently maintained. Clearances must also accommodate an installation’s gas, electri- cal, and drain trap and drain line connections. If the alternate combustion air intake or vent/flue connections are used additional clearance must be provided to accommodate these connections. Refer to Vent/FluePipeandCombustionAirPipe 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.

H orizon tal

Afurnace 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 Specification Sheet applicable to your model for minimum clearances to combustible surfaces. One of the ventila- tion openings must be within 12 inches of the top; the other open- ing must be within 12 inches of the bottom of the confined space. In a typical construction, the clearance between the door and door frame is usually adequate to satisfy this ventilation requirement.

FURNACESUSPENSION

If suspending the furnace from rafters or joists, use 3/8" threaded rod and 2”x2”x1/8” angle iron as shown in the following diagram. The length of rod will depend on the application and the clearances necessary.

NOTE: When an existing furnace is removed from a venting sys- tem serving other appliances, the venting system may be too large to properly vent the remaining attached appliances.

The following vent testing procedure is reproduced from theAmerican

NationalStandard/NationalStandardofCanadaforGas-FiredCentral FurnacesANSI Z21.4, CSA-2.3 latest edition 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 connected to the venting system are not in operation:

1. Seal any unused openings in the venting system;
