Installer’s Guide
▲! CAUTION
To prevent shortening its service life, the furnace should not be used as a “Construction Heater” during the finishing phases of construction until the require- ments listed in item 9,
▲! CAUTION
Do NOT install the furnace in a corrosive or contami- nated atmosphere.
▲! WARNING
EXPLOSION HAZARD!
PROPANE GAS IS HEAVIER THAN AIR AND MAY COLLECT IN ANY LOW AREAS OR CONFINED SPACES. IN ADDITION, ODORANT FADE MAY MAKE THE GAS UNDETECTABLE EXCEPT WITH A WARN- ING DEVICE. IF THE GAS FURNACE IS INSTALLED IN A BASEMENT, AN EXCAVATED AREA OR A CONFINED SPACE, IT IS STRONGLY RECOM- MENDED TO CONTACT A GAS SUPPLIER TO IN- STALL A GAS DETECTING WARNING DEVICE IN CASE OF A GAS LEAK.
NOTE: The manufacturer of your furnace does NOT test any detectors and makes no representations regarding any brand or type of detector.
LOCATION AND CLEARANCES
The location of the furnace is normally selected by the ar- chitect, the builder, or the installer. However, before the fur- nace is moved into place, be sure to consider the following requirements:
1.Is the location selected as near the vent and as cen- tralized for heat distribution as practical?
2.Do all clearances between the furnace and enclosure equal or exceed the minimums shown in the Table 1.
3.Is there sufficient space for servicing the furnace and other equipment? A minimum of 24 inches front acces- sibility to the furnace must be provided. Any access door or panel must permit removal of the largest com- ponent.
4.Are there at least 3 inches of clearance between the fur- nace front panel and any closed panel or door provided?
5.Are the vent pipe and combustion air inlet pipe within vent table lengths? Will the pipes remain unobstructed?
6.Allow sufficient height in supply plenum above or below the furnace to provide for cooling coil installation if the cooling coil is not installed at the time of this furnace installation.
7.A furnace shall be installed so electrical components are protected from water.
8.If the furnace is installed in a residential garage, it must be installed so that the burners and the ignition source are located not less than 18 inches (46 cm) above the floor and the furnace must be located or pro- tected to avoid physical damage from vehicles.
IMPORTANT:
The furnace must be installed level. The only allowable variation would be slightly to the left and/or forward in up- flow installations or slightly toward the front in horizontal in- stallations. This is necessary for proper condensate drain- age.
