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.
a
WARNING: Never use an
open flame to check for a leak.

nal regulator has been installed
between propane/LP supply and
fireplace. See guidelines under
Connecting to Gas Supply,
pages 16 and 17.
Pressure Testing gas Supply Piping
System
Test Pressures in Excess 01112 PS1G (3.5 kPa)
I. Disconnect appliance with its appliance main
gas valve (control valve) and equipment
shutoff valve from gas supply piping system.
Pressures in excess of 1/2 psig will damage
heater 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 or opening main gas valve lo-
cated 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 fit-
tings for leaks.
Test Pressures Equal To or Less Than 1/2 PS1G
(33 kPa)
I. Close equipment shutoff valve (see Figure 24).
Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve lo-
cated on or near gas meter for natural gas, or
using compressed air.
3.
Check all joints from gas meter to equipment
shutoff valve for natural gas or propane/LP
supply to equipment shutoff valve for propane/
I,P(sce Figures 25 or 26. page 19). Apply non-
corrosive leak deteelion fluid to all joints.
Bubbles forming show a leak.
