* The CSA design-certified equipment shutoff
valve may be supplied with the appliance or you
can purchase it from your retailer.
We recommend that you install a sediment trap/drip
leg in supply line as shown in Figure 32. Locate
sediment trap/drip leg where it is within reach for
cleaning. Install in piping system between fuel
supply and fireplace. Locate sediment trap/drip
leg where trapped matter is not likely to freeze. A
sediment trap traps moisture and contaminants. This
keeps them from going into fireplace gas controls. If
sediment trap/drip leg is not installed or is installed
wrong, fireplace may not run properly.

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 detection fluid
to all 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 fireplace and its individual equip-
ment shutoff valve from gas supply piping
system. Pressures in excess of 1/2 psig (3.5 kPa)
will damage fireplace gas regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas fireplace or opening main gas
valve located on or near gas meter for natural
gas fireplace or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak. Correct
all leaks at once.
5. Reconnect fireplace and equipment shutoff
valve to gas supply. Check reconnected fittings
for leaks.

Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not pro-
vided)
1. Open lower louver door panel by gently
pulling forward.
2. Route flexible gas line (provided by installer)
from equipment shutoff valve to fireplace.
Route flexible gas supply line through one
of the access holes on side of fireplace.
3. Attach flexible gas line from gas supply
to control valve (see Figure 33).
4. Check all gas connections for leaks. See
Checking Gas Connections.
