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.
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 30
).
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 31 or Figure 32
)
. Apply
noncorrosive leak detection fluid to all joints. Bubbles forming
show a leak.
4. Correct all leaks at once.

PRESSURE TESTING FIREPLACE GAS CONNECTIONS
1. Open equipment shutoff valve
(see
Figure 30
).
2. Open propane/LP supply tank valve for propane/LP fireplace
or main gas valve located on or near gas meter for natural gas
fireplace.
3. Make sure control knob of fireplace is in the OFF position.
4. Check all joints from equipment shutoff valve to gas valve
(see
Figure 31 or Figure 32
)
. Apply noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak. Correct all leaks at once.
5. Light fireplace
(see Operation,
Page 28
)
. Check all other internal
joints for leaks.
6. Turn off fireplace
(see To Turn Off Gas to Appliance,
Page 33
).
FINISHING FIREPLACE FOR INSTALLATION
DRL4543 series fireplace come with the rear panel semi-installed.
If you will be using the fireplace for a one sided regular application,
you will need to finish the installation of the rear panel. If you will be
upgrading the fireplace to a see-thru, the rear panel will need to be
removed (See Upgrading DRL4543 Series to See-Thru Application
Page 29).
1. Using self-tapping screws provided and holes on rear panel as a
guide, screw the rear panel to the fireplace as shown in
Figure 33,
