

All models can be installed in either a horizontal or vertical

position Horizontal installs must have the gas line positioned on

top, vertical installs must have vent located at the floor and gas

line on the right side.



Always install furnace exhaust system through an exterior wall.



DO NOT install furnace near tilt-out rooms, slide-outs, doors or

other projection that could obstruct furnace exhaust.



Locate furnace near midpoint of coach for single furnace

applications.



Installation must provide accessibility if any repairs are necessary

to the furnace. Failure to meet this requirement will create

additional labor costs that will be the responsibility of the installer.



DO NOT install vent in areas where projection or door openings

come within 6" of vent opening.



DO NOT install furnace in an area where wires, pipes or other

objects will interfere with installation or removal for servicing or

operation of furnace.



DO NOT install furnace on material that restricts return air, such

as directly on carpet, or soft material (like vinyl). If you must install

furnace on carpet or soft material, install furnace on cleats, or on

a wood or metal panel extending the full width and depth of

furnace plus minimum clearance to combustibles requirements.



DO NOT use petroleum or citrus base cleaner on plastic parts, as

damage may occur.



NOTE: The exhaust temperature of this furnace could discolor or

warp some materials. You should verify that the material used on

coach door, panel, or covers will not discolor, warp or burn from

the exhaust temperature whenever placed directly in front of vent.



CAUTION: Due to the differences in vinyl siding materials this

appliance should not be installed without first consulting with the

manufacturer of the siding or cutting the siding away from the

area around the appliance vent.



A gas-fired furnace for installation in a residential garage must be

installed so the burner(s) and the ignition source are located not

less than 18 in (457mm) above the floor and the furnace must be

located and protected to avoid physical damage by vehicles.



DO NOT use petroleum or citrus type cleaner on plastic parts, as

damage may occur.

CLEARANCE TO COMBUSTIBLES

Floorboards, walls & similar combustible building materials must

maintain clearances given and must be provided the full length and

width of the unit. Spacing is given based on the installed position of the

furnace.



Spacing of 1/4" to ducting within 3 feet of furnace must be

provided unless UL listed wire bound vinyl ducts are used. All

ducting material must be rated for continuous use at minimum of

200°F.



Clearances are specifically for plywood or similar building

materials surrounding the furnace (i.e. Furnace should not be

located under furniture or in a closet space where clothing or

other material could be located).



Furnace efficiency rating is a thermal rating determined under

continuous operating conditions, independent of any installation.

Efficiency rate is given at 76% minimum; actual efficiency rating

may be higher.



Return air is supplied through openings in and around the

furnace. All return air passages must be kept clear for furnace to

function properly.



The total unobstructed return air opening size must not be less

than specified in these instructions. Failure to meet minimum

return air requirements nullifies furnace warranty.



To install without the additional 16 in

supply blower side of unit with 2" clearance full height length and

width of the unit.

REQUIRED DUCTING

All ducts in the table are four-inch ducts except for front discharge as

noted. Two-inch ducts cannot be used in place of one four. A front

discharge system using a five-inch duct requires no other ducts

maximum length 12".

Optional five-inch to four-inch adapter ducting can be purchased to

allow four-inch duct in addition (1) four-inch or (2) two-inch ducts must

also be used when using four-inch front option. Front duct must not

exceed 12".

FOR OPTIMAL PERFORMANCE:

Use the following ducting recommendations. Top Duct is used only in

addition to these requirements and is not allowed to be used until

these requirements are met. Additional ducting when added will reduce

the airflow through the ducting and improper ducting could cause poor

heating and or cycling on high temperature limit.

 Horizontal or Vertical 4" Ducting; when using 4" ducting one

duct from each side must be used. Unless the front discharge is

used with either the 5" duct and grill or optional 4" ducting.

 'No Bottom Discharge system allowed".
