CONNECTIONS
1. Open equipment shutoff valve (see Figure
16, page 13).
2. For natural gas open main gas valve
located on or near gas meter. For pro-
pane/LP gas open propane/LP supply
tank valve.
3. Make sure control knob of heater is in the
OFF position.
4. Check all joints from equipment shutoff
valve to thermostat gas valve (see Figure
17 or 18). Apply a noncorrosive leak de-
tection fluid to all joints. Bubbles forming
show a leak.
5. Correct all leaks at once.
6. Light heater (see
Operating Heater

CONNECTING TO ELECTRICAL
SUPPLY)
WARNING: Fan accessory
must be grounded. Fan comes
with a three-prong, grounding
plug as shown in Figure 19. The
plug is your protection against
electrical shock. Plug it into a
standard, three-hole, grounded,
outlet. If cord needs replacing,
use only a cord with a three-
prong, grounding plug.
CAUTION: Label all wires
prior to disconnection when
servicing controls. Wiring errors
can cause improper and danger-
ous operation (see page 26).

EXTENSION CORD
Use extension cord if needed. The cord must
have a three-prong, grounding plug and a
three-hole receptacle. Make sure cord is in
good shape. It must be heavy enough to carry
the current needed. An undersized cord will
cause a drop in line voltage. This will result
in loss of power and overheating. Use a No.
16 AWG cord for lengths less than 50 feet
(15.24 m).
CAUTION: Verify proper op-
eration after servicing.
