DOWNFLOW WARNING (*RL Models):

The design of the downflow furnace is certified for natural or propane gas and for installation on non-combustible flooring. A special combustible floor sub-base is required when installing on a combustible floor. Failure to install the sub-base may result in fire, property damage and personal injury. The special downflow sub-bases are fac- tory supplied accessories, part number 902974, 902677, 904108 and 904165. Part #904108 is an adjustable sub-base kit and it can be used on all cabinet sizes. When the furnace is installed on a factory or site-built cased air conditioning coil, the sub-base is not necessary. However, the plenum attached to the coil casing must be installed such that its surfaces are at least 1” from combustible construction.

A gas-fired furnace installed in a residential ga- rage must be installed so that the burners and the ignition source are located a minimum of 18” from the floor.The furnace must be located or protected to avoid physical damage by vehicles.

Location

The furnace must be installed on a level surface, and as close to the center of the air distribution system as possible. See Table 3 for overall di- mensions to determine the required clearances in hallways, doorways, stairs, etc. to allow the furnace to be moved to the installation point.The furnace must be installed so that all electrical components are protected from water.

Minimum clearances to combustible materials are listed in Table 4. Access for positioning and servicing must be considered when locating the unit. Twenty four inches is the minimum required clearance for servicing the unit. Thirty inches is the minimum required clearance for positioning the unit. Thirty six inches is the recommended clearance from the front of the unit. Please note that a panel or door can be located such that the minimum clearance on the rating plate is satis- fied, but that panel or door must be removable and allow the appropriate clearance for your installation.
