We recommend that you install a sediment
trap/drip leg in supply line as shown in Figure
28, page 17. Locate sediment trap/drip leg
where it is within reach for cleaning. Install
in piping system between fuel supply and
burner system. Locate sediment trap/drip leg
where trapped matter is not likely to freeze.
A sediment trap traps moisture and contami-
nants. This keeps them from going into burner
system gas controls. If sediment trap/drip leg
is not installed or is installed wrong, burner
system may not run properly.
CONNECTING STOVE/BURNER
SYSTEM TO GAS SUPPLY
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not
provided)
1. Open lower door panel.
2. Route flexible gas line (provided by install-
er) from equipment shutoff valve to burner
system (see Figure 29). Route flexible gas
supply line and attach to valve.
3. Check all gas connections for leaks. See
Checking Gas Connections, column 2.

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 flame to check for a leak.
Apply noncorrosive leak test so-
lution to all gas joints. Bubbles
forming show a leak. Correct all
leaks at once.
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
systems. Pressures in excess of 1/2 psig
(3.5 kPa) will damage burner system gas
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 burner system or open-
ing main gas valve located on or near gas
meter for natural gas burner system, or
using compressed air.
4. Check all joints of gas supply piping sys-
tem. Apply noncorrosive leak test solution
to all gas joints. Bubbles forming show a
leak. Correct all leaks at once.
5. Reconnect burner system and equipment
shutoff valve to gas supply. Check recon-
nected fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure
30, page 19).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas burner system or opening
main gas valve located on or near gas
meter for natural gas burner system, or
using compressed air.
