Safety Information
DANGER
Danger of explosion.
There are circumstances in which odorant used with LP/propane gas can lose its scent. In case of a leak, LP/propane gas will settle close to the floor and may be difficult to smell. An LP/propane leak detector should be installed in all LP applications.
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause property damage, person- al injury or loss of life. Installation and service must be performed by a licensed professional installer (or equivalent), service agency or the gas supplier.
CAUTION
As with any mechanical equipment, personal injury can result from contact with sharp sheet metal edges. Be careful when you handle this equipment.
Certifications
EL280DF units are CSA International certified.
In the USA, installation of gas furnaces must conform with local building codes. In the absence of local codes, units must be installed according to the current National Fuel Gas Code

Clearances
Adequate clearance must be made around the air open- ings into the vestibule area. In order to ensure proper unit operation, combustion and ventilation air supply must be provided according to the current National Fuel Gas Code. Vent installations must be consistent with the National Fuel Gas Code venting tables (in this instruction) and applicable provisions of local building codes.
This furnace is CSA International certified for installation clearances to combustible material as listed on the unit nameplate and in the tables in figure 13. Accessibility and service clearances must take precedence over fire protection clearances.
Installed Locations
For installation in a residential garage, the furnace must be installed so that the burner(s) and the ignition source are located no less than 18 inches (457 mm) above the floor. The furnace must be located or protected to avoid physical damage by vehicles. When a furnace is installed in a public garage, hangar, or other building that has a haz- ardous atmosphere, the furnace must be installed accord- ing to recommended good practice requirements and cur- rent National Fuel Gas Code.
NOTE − Furnace must be adjusted to obtain a temperature rise within the range(s) specified on the unit nameplate. Fail- ure to do so may cause erratic limit operation and may also result in premature heat exchanger failure.
This EL280DF furnace must be installed so that its electri- cal components are protected from water.
Installed in Combination with a Cooling Coil
When this furnace is used with cooling units, it shall be installed in parallel with, or on the upstream side of, cooling units to avoid condensation in the heating compartment. With a parallel flow arrangement, a damper (or other means to control the flow of air) must adequately prevent chilled air from entering the furnace (see figure 1). If the damper is manually operated, it must be equipped to pre- vent operation of either the heating or the cooling unit, un- less it is in the full HEAT or COOL setting.
