CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply and
fireplace. See guidelines under
Connecting Fireplace to Gas
Supply, page 14.
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 21).
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.
3. Check all joints from gas meter to equipment
shutoff valve for natural gas or propane/LP sup-
ply to equipment shutoff valve for propane/LP
(see Figures 22 and 23). Apply noncorrosive
leak detection fluid to all joints. Bubbles form-
ing show a leak.
4. Correct all leaks at once.

CONNECTIONS
1. Open equipment shutoff valve (see Figure 21).
2. Open main gas valve located on or near gas
meter for natural gas or open propane/LP
supply tank valve.
3. Make sure control knob of fireplace is in the
OFF position.
4. Check all joints from equipment shutoff valve
to gas control valve (see Figures 22 or 23).
Apply noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light fireplace (see Operating Fireplace, page
17. Check all other internal joints for leaks.
7. Turn off fireplace (see To Turn Off Gas to
Appliance, page 18).
