STEP 6.
To place furnace into position, grasp furnace and lift so furnace flue
vent and header plate vent opening engage. Do not use burner or
gas control to lift heater. Lift furnace upward and swing bottom into
wall opening until legs rest on floor plate and are flush to finished
wall. For proper combustion, level heater front to back and side to
side. Nail legs to studs.
DO NOT BEND LEGS
as this will put the
entire unit into a bind and cause expansion noises.
(See Figure 9-A)
STEP 7.
A drip leg and a manual valve equipped with a 1/8 N.P.T. plugged
tapping accessible for test gauge connection should be installed
immediately upstream of the gas supply connection to the appliance.
Some codes and ordinances require that the manual valve be
located outside the appliance.
STEP 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.
STEP 9.
For wall thermostat units, see “Wiring” section for thermostat
connections. Make sure all connections are correct and connector
stems are not touching.
STEP 10.
To fasten front panel to furnace, be sure exposed portion of header
is free of debris. Place outer panel over furnace with top of panel
about one inch above header and centered in opening. Keep front
panel flush to finished wall and slide down until rear flange of top
outer panel is wedged tight against the front of the plaster ground
channel and flush with wall.
CAUTION: DO NOT HANG FRONT
PANEL BEHIND (OVER FRONT LIP) THE PLASTER GROUND
CHANNEL AS THIS COULD RESULT IN EXCESSIVE NOISE.
Open bottom door of front panel and place sheet metal screw into
locking latch. Secure top of front panel to header plate with screw
provided. This will hold front panel securely to wall.
See Figures 7-B and 7-C (on page 10) and 9-C (to the left).
