INSTALLATION
Continued
We recommend that you install a sediment
trap in supply line as shown in
Figure 14,
Page 14
. Locate sediment trap where it is
within reach for cleaning. Install in piping
system between fuel supply and appliance.
Locate sediment trap where trapped matter
is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them
from going into appliance controls. If sediment
trap is not installed or is installed wrong, ap-
pliance may not run properly.
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting
it to gas piping and/or fi ttings.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an
open fl ame to check for a leak.
Apply a noncorrosive leak detec-
tion fl uid to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply
and appliance. See guidelines
under Connecting to Gas Sup-
ply, Page 13.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply piping
system. Pressures in excess of 1/2 psig
(3.5 kPa) will damage appliance regulator.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
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 noncorrosive leak detection fl uid to
all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect appliance and equipment
shutoff valve to gas supply. Check recon-
nected fi ttings for leaks.
Test Pressures Equal To or Less Than 1/2
PSIG (3.5 kPa)
1. Close equipment shutoff valve
(see Fig-
ure 15).
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
natural gas or using compressed air.
3. Check all joints from gas meter to equip-
ment shutoff valve for natural gas or
propane/LP supply to equipment shutoff
valve for propane/LP
(see Figure 16 or
Figure 17, Page 16).
Apply noncorrosive
leak detection fl uid to all joints. Bubbles
forming show a leak.
4. Correct all leaks at once.
