CHECKING GAS CONNECTIONS
WARNING: Test all gas pip-
ing and connections, internal
and external to unit, for leaks
after installing or servicing. Cor-
rect all leaks at once.
WARNING: Never use an
open flame to check for a leak.
Apply a noncorrosive leak
detection fluid 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
fireplace. See guidelines under
Connecting Fireplace to Gas
Supply, page 15.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect fireplace with its main gas valve
(control valve) and equipment shutoff valve from
gas supply piping system. Pressures in excess of
1/2 psig will damage fireplace 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 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 fluid to all
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. 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 17).
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.
