3. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for
natural gas or using compressed air.
4. Check all joints of gas supply piping system.
Apply a noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected
fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see
Figure 18).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for

3. Check all joints from gas meter for natural
gas (see Figure 19) or propane/LP supply
tank for propane/LP gas, to equipment
shutoff valve (see Figure 20). Apply a

WARNING: Fan accessory
must be grounded. Fan comes
with a three-prong, grounding
plug as shown in Figure 21, page
15. 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 27).
