NOTE: For proper combustion, make sure units are level front to back and side to side.
RECESSED UP TO 9-1/4" INSTALLATION
1.
Cut out floor plate between 2x4 studs, so heater will set flat on floor.
2.
Make electrical connection of 115 V. wiring into junction box provided on top of header
plate.
3.
Attach the base plate (purchased with the vent pipe) to the header plate using two No.
8 sheet-metal screws through the pre-punched holes. See Figure 12.
4.
Square up and nail header plate in place between 2x4 studs placed on 16" centers
(14-3/8" between studs). For distances from top of header plate to floor, see Figure 10.
5.
Remove double ceiling plate between studs. Install one ceiling plate spacer across the
cut out in ceiling plate. Install vent pipe into position, be sure to lock bottom of vent pipe
into the base plate. Nail second ceiling plate spacer in place. See Figure 12.
6.
If the vent continues through additional stories within the 2x4-stud space, then fire stop
spacers must be installed at the second and subsequent ceiling levels. See Figure 13.
7.
To place furnace into position, grasp furnace and lift so furnace flue vent and header
plate vent opening engage. Plug power cord from top of heater into receptacle on
bottom of the header plate, see Figure 7 (on page 9).
Run thermostat wire through a drilled hole into an adjacent stud space. Do not route it
behind the header plate. To do so may cause the thermostat wiring to chaff resulting
in the appliance operating continually. Connect thermostat wire with thermostat wires
extending from top of heater. Lift furnace upward and swing bottom into wall, see
Figure 11.
Secure furnace in place using the two holes provided at the bottom of the casing.
8. Make gas connection using connector the same size as gas connection of furnace.
CHECK ALL CONNECTIONS FOR GAS LEAKS WITH LEAK DETECTOR SOLUTION.
DO NOT USE OPEN FLAME.
9.
Replace and fasten front panels to furnace.
FLUSH TO WALL INSTALLATION
1.
After locating furnace, cut 3-1/2"x12" rectangular hole in ceiling between ceiling joists.
Make sure gasket is in position on the top of the furnace casing around the flue vent
opening. Remove vent collar from top of header plate and place over flue extension
and fasten to matching holes in casing top, using screws from header plate.
Install B vent type base plate (not supplied) to top of vent collar. Install ceiling plate
spacer to back wall, centered between studs. Install B type vent to top of furnace,
terminating at least 12' above the floor and at least 2' above the roof line.
2.
Fasten furnace to wall. To secure top of furnace to wall, loosen top screws on back
casing and raise tabs up. Tighten screws. Screw through hole in top of tabs into anchors
(not provided). Secure bottom using two holes provided in bottom of casing. (Optional)
Cover exposed vent with a vent enclosure kit, Part Number 16VE-A or 36VE-A (not
included).
3.
Make electrical connection of 115 V. wiring into receptacle box (not provided) mounted
on a wall. Plug power cord from top of heater into receptacle. Connect thermostat
wire with thermostat wires extending from top of heater. According to installation
instructions with thermostat, do not run wires in same stud space with vent system.
Thermostat should be a minimum of 4' from heater and 5' from floor.
4.
Make gas connection using connector the same size as gas connection of furnace.
CHECK ALL CONNECTIONS FOR GAS LEAKS WITH LEAK DETECTOR SOLUTION.
DO NOT USE OPEN FLAME.
5.
Replace and fasten all front panels.
