Superior DRT4036TEN Installation And Operation Instructions Manual page 16

WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap/drip leg in supply line
as shown in Figure 22, page 15. 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 equipment 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.

CONNECTING FIREPLACE TO GAS SUPPLY
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not provided)
1. 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.
2. Attach flexible gas line from gas supply to control valve (see Figure
23).
3. Check all gas connections for leaks. See Checking Gas Connec-
tions.

5. Reconnect fireplace 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 24).
2. 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.
3. Check all joints from propane/LP supply tank or gas meter to
equipment shutoff valve (see Figure 25 or Figure 26, page 17).
Apply noncorrosive leak detection fluid to all joints. Bubbles form-
ing show a leak.
4. Correct all leaks at once.
